Why This Guide Is Different
This guide offers nuance! As a naturopathic physician with training in respiratory health and organic chemistry, I take your concerns about adhesive off-gassing and how to safely deal with it seriously, never using the dismissive “levels are so low they won’t harm you” trope, but also avoiding unnecessary fear. I consider curing chemistry, whether or not natural glues function well, link to helpful research, and then organize the information into a neat visual rating scale you can use when making decisions about home products containing glues.

Keep reading for the full breakdown on the reasoning behind the scale, and how to make smart decisions about adhesives in your home.
Natural/Traditional Adhesives
Are there non-toxic natural glues for furniture?
Yes, several traditional adhesives are made entirely from natural materials and remain available today, though they're less common in mass-produced furniture.
What is hide glue?
Hide glue is water mixed with connective tissue from animal hides. It's naturally VOC-free and was the "original glue" used for thousands of years in furniture making. While not commonly used in manufactured or commercial wood furniture that requires high durability, hide glue remains an option for home projects and lighter-weight work—Titebond still makes it. Hide glue creates strong bonds that can be reversed with heat and moisture, making it ideal for furniture repair and restoration.
Is cellulose glue safe?
Yes, cellulose glue is one of the safest adhesive options. It's simply water mixed with wood pulp and can be used for light hobby woodworking projects. It's biodegradable, non-toxic, and produces no VOC emissions.
Can flour be used as glue?
Yes, flour mixed with water creates a safe, natural adhesive because the gluten in flour acts as a binder. This mixture is actually still used as wallpaper paste for breathable, natural wallpapers. It's completely non-toxic and has been used for centuries.
What is wheat paste wallpaper adhesive?
Wheat paste (also called wheat starch paste) is made by mixing wheat flour or wheat starch with water to create a thick, sticky paste for hanging wallpaper. It's one of the oldest and safest wallpaper adhesives, used for hundreds of years. Wheat paste works best with breathable, natural wallpapers like paper-based or fabric wallcoverings. It's completely biodegradable, non-toxic, and produces zero VOCs.
Is potato starch wallpaper paste safe?
Yes, potato starch paste is another natural, non-toxic wallpaper adhesive option. Like wheat paste, it's made by mixing potato starch with water. It's ideal for people with wheat allergies or gluten sensitivities who want to avoid wheat-based pastes. Potato starch paste is biodegradable, produces no VOCs, and works well with natural, breathable wallpapers.
Where are natural adhesives used in home decor and furniture?
Natural adhesives might be in:
Antique and reproduction furniture (hide glue)
Specialty woodworking (hide glue)
Natural wallpaper installation (wheat paste, potato starch paste, flour paste)
Craft and hobby projects (cellulose glue, flour paste)
Furniture restoration and repair (hide glue)
Water-Based Synthetic Adhesives
Are water-based glues safe?
Water-based synthetic adhesives are generally among the safest modern adhesive options. While they're made with synthetic polymers (plastics), they contain minimal VOCs and toxic chemicals compared to solvent-based alternatives.
What is PVA glue?
PVA (polyvinyl acetate) is the most common type of modern wood glue and furniture adhesive. It's basically water mixed with plastic polymers. This is what Elmer's craft glue, "wood glue," and "carpenters glue" typically contain. PVA glues are some of the least toxic adhesive types even when wet, and they cure by water evaporation rather than chemical reaction, producing minimal off-gassing.
Is wood glue toxic?
It depends on what kind you're using. Wood glue toxicity varies dramatically based on whether it's water-based or solvent-based, and what additional chemicals are included in the formulation. Water-based PVA wood glues are generally quite safe, while solvent-based wood glues can contain formaldehyde, xylene, toluene, and other harmful VOCs.
Are zero-VOC water-based wood glues safe?
Yes, zero-VOC water-based wood glues are truly a relatively non-toxic choice that's effective at holding furniture together. Brands like ECOS make wood glues in this category, and glues with GreenGuard GOLD certification fall into this rating as well. These products cure by water evaporation and create minimal indoor air quality concerns.
What is EVA adhesive?
EVA adhesive (also called "hot melt adhesive") is a mixture of EVA and other ingredients like low-VOC resins and waxes. EVA is short for ethylene vinyl acetate. Even though it contains the word "vinyl," its chemical structure and properties are very different from PVC (polyvinyl chloride, also just called "vinyl"). EVA is not carcinogenic and is generally a much safer plastic-based adhesive choice.
Is EVA adhesive toxic?
Generally, no. EVA is what shower curtains are made of—it's generally inert and non-toxic to people. You encounter it in peel-and-stick wallpaper backing and some non-toxic craft glues, but actual contact is rare (you might touch the adhesive backing once or twice when applying wallpaper, for example). It's not perfectly healthy, but pretty good, and falls under the "water-based, synthetic, zero-VOC" rating.
What is the difference between low-VOC and zero-VOC glue?
Zero-VOC glues contain virtually no volatile organic compounds and produce minimal off-gassing, while low-VOC glues contain slightly more VOCs—you may notice minimal off-gassing during application and curing. Both are significantly safer than solvent-based adhesives.
Where are water-based adhesives used in home decor and furniture?
Water-based synthetic adhesives appear in:
Most modern wood furniture assembly
Peel-and-stick wallpaper backing (EVA)
Some upholstery applications
Mattress construction (in better-quality mattresses)
Picture framing
Solvent-Based Adhesives (Including Formaldehyde-Based)
What are solvent-based glues?
Solvent-based adhesives are the classic, strongly-smelling glues that off-gas intensely. They use chemical solvents to keep the adhesive in liquid form and often contain formaldehyde, polyurethane, xylene, toluene, and other harmful VOCs.
What are solvents in glue?
Solvents are chemicals that keep adhesives in liquid form inside the tube or container—they're one of the main reasons glues off-gas VOCs. They keep substances liquidy and evenly dispersed until application. Solvents evaporate from products as they dry, and inhalation is one of the primary exposure pathways. They can also be absorbed through skin during direct contact.
Are solvent-based glues toxic?
Yes, solvents are one of the priority chemicals to avoid because of their toxic impacts on the respiratory system, neurological health, and links to cancer. Many solvent-based glues contain formaldehyde, polyurethane, xylene, and toluene—all harmful VOCs that off-gas intensely. You'll notice them in cheaper furniture, and they can take weeks to months to fully off-gas.
What is formaldehyde in glue?
Formaldehyde is a gas, or a Volatile Organic Compound (VOC.) It is made in a chemical factory or laboratory by oxidizing methanol. In 2006, 12 million tons were produced, and in 2024, an estimated 51 million tons were made. It is used to make glues (as well as wood finishes, wrinkle-resistant fabric finishes, melamine, plywood, MDF, particleboard, carpeting, foam insulation, and paint, and is the precursor to diisocyanates, which make polyurethane foam. It’s also used in non-home goods, like fertilizers, pesticides, nail polish, hair straightening products, and for purposes like embalming or preserving cosmetics. In short, it is a very popular chemical with many uses.
Why is formaldehyde used in furniture glue?
Formaldehyde makes furniture glue very strong, fast-drying, and resistant to heat and water. It's also inexpensive compared to formaldehyde-free alternatives, which is why it remains popular in furniture manufacturing.
Formaldehyde-based adhesives are also used within engineered wood products like particleboard, plywood, and MDF, where wood particles are mixed with formaldehyde-containing resins.
Is formaldehyde in glue dangerous?
Yes. Formaldehyde is known to be a human carcinogen, as established by the US National Toxicology Program in 2011, and supported by the EPA, the International Agency for Research on Cancer (IARC) and the American Cancer Society (ACS). It is associated with leukemia and nasal cancer.
Because it is used in so many places and because it is so volatile — meaning it evaporates from products into the air very easily— it is considered a major danger to health. It can also cause irritation of the skin, eyes, nose and throat. In some sensitive people, formaldehyde in moisturizers and makeup can cause an allergic skin reaction called allergic contact dermatitis.
How are you exposed to formaldehyde?
The main way you are exposed to formaldehyde is by breathing it in from products that off-gas it into the air.
How long does formaldehyde off-gas from furniture?
Most formaldehyde releases from furniture over approximately two years, but the timeline varies significantly based on the product type and your home's environmental conditions. Off-gassing can take as little as several weeks or as long as several years for formaldehyde to completely finish releasing. The rate depends on how much formaldehyde the product contains and on temperature, humidity, and ventilation levels. Formaldehyde off-gasses faster at high temperatures and high humidity, and lingers longer in poorly ventilated spaces. Off-gassing is most intense during the first few weeks, then slows progressively over time.
How long does new furniture off-gas?
Most formaldehyde and other VOCs are released from products over two years, but depending on the product and the conditions of your home, it can take as little as several weeks to as much as several years for formaldehyde to completely finish off-gassing. The speed will depend on how much formaldehyde is present in the product, and on temperature, humidity, and ventilation of the home it is in. Formaldehyde will off-gas faster at high temperatures and high humidity, and it will stay in the air longer if ventilation is poor. Formaldehyde off-gasses most intensely in the first few weeks, and slows down over time.
Once a solvent-based glue cures, is it still toxic?
Once a solvent-based adhesive has completely cured—meaning it's not only dry but all the chemicals have fully reacted together, making it chemically inert—it off-gasses much less and becomes much less toxic. However, complete curing can take weeks to months for solvent-based glues. If a furniture brand uses standard solvent-based adhesives, the product may have finished off-gassing by the time it reaches you, or it may still be actively releasing VOCs. Ventilate until a neighbor who comes over can't smell it anymore (your own nose adapts and stops detecting it).
How much formaldehyde is in home air?
In older homes without new furniture, fresh paint, or other formaldehyde sources, formaldehyde levels naturally remain below 0.1 parts per million. Some baseline formaldehyde exposure is normal and impossible to completely eliminate, but elevated levels create health problems.
How can I reduce formaldehyde from furniture?
Formaldehyde will naturally be removed from furniture over time through off-gassing, but you can speed this up, or limit how much you’re exposed to, in 4 ways:
Ventilate daily by opening your windows.
Use an air purifier that is specifically able to capture gasses like formaldehyde. Most air purifiers cannot remove formaldehyde from the air, because it’s too small to be caught by a HEPA filter— you can see why visually in this guide. However, some air purifiers do contain formaldehyde-capturing minerals like activated charcoal or potassium, and these can help reduce indoor levels. These are the ones I recommend.
Let new products off-gas outside of the home, like in the garage, shed, or backyard, before bringing them in for use.
Use the bake out method very, very carefully (read more below)
Should I use the bake-out method to remove formaldehyde faster?
The bake out method consists of closing all of your windows and turning up the heat to encourage formaldehyde and other gasses to come out of furniture. Afterward, the heat is turned off, and all the windows are opened to throughly ventilate the formaldehyde (and other VOC) -rich air into the outdoors. The origin of this idea is solid: using infrared technology in a lab setting effectively “bakes out” VOCs from high VOC building materials, and the technique is sometimes done after a new building is finished, before residents move in. These processes are highly controlled and measured, and involve a limited number of building materials, rather than an entire set of products and chemicals that are generally kept in a home. Because of that, the CDC does not recommend using this method on your own. This is valid for 3 reasons:
Inadequate ventilation risk: A DIY home bake-out can raise indoor VOC levels, and the ventilation process afterward may be inadequate to fully remove them. If you do this, be sure you are using ample exhaust fans and thoroughly circulating all air out of the home. Do not rely on windows alone, as simply opening them won’t necessarily be enough to move air out. An indoor air quality monitor can be helpful in monitoring to make sure you do it correctly, if you decide to do a bake out. Although no home monitors are advanced enough to detect formaldehyde as a distinct chemical separate from other VOCs (ignore any brands that say they can— it’s not true!), you will still be able to see an overall VOC reading, and you should wait to go inside until the numbers to go down to ambient levels (usually around 400 ppb).
Chemical reaction concerns: Heating up a room releases not just formaldehyde from a limited number of building materials or particular products— but all VOCs from all products in the home, and these can potentially combine into new, more harmful compounds. VOCs are very reactive with each other and other components of the air, like particulate matter.
Re-absorption problems: Increasing the concentration of VOCs in the air can mean that other products absorb them before the windows are opened, and retain them. Different materials hold on to different VOCs for different lengths of time, so this can introduce new problems.
Overall, there are no studies done to confirm that an at home DIY bake out is effective or safe. If you do so anyway, caution is advised!
Can glue fumes trigger asthma?
Yes, VOCs from solvent-based adhesives are known respiratory irritants that can trigger asthma attacks in people with existing asthma. The solvents in these glues—particularly formaldehyde, toluene, and xylene—irritate the airways, causing inflammation, bronchoconstriction, and increased mucus production. Even in people without diagnosed asthma, prolonged exposure to adhesive VOCs can cause new-onset asthma or occupational asthma. Children are particularly vulnerable because their respiratory systems are still developing and they breathe more air per pound of body weight than adults.
Do adhesive fumes make allergies worse?
Yes, VOC exposure from adhesives can exacerbate existing allergies and increase overall allergen sensitivity. Formaldehyde and other VOCs irritate mucous membranes in the nose, throat, and eyes, making you more reactive to other allergens like pollen, dust, or pet dander. This happens because VOCs cause low-level inflammation in your respiratory system, lowering the threshold at which your immune system reacts to other triggers. Some people also develop allergic contact dermatitis from direct skin contact with certain adhesives.
Can formaldehyde cause headaches?
Yes, formaldehyde exposure commonly causes headaches, along with dizziness, nausea, and fatigue. These neurological symptoms occur because formaldehyde affects the central nervous system. The headaches typically worsen with continued exposure and may be accompanied by difficulty concentrating, irritability, and sleep disturbances. If you notice persistent headaches after bringing new furniture into your home, formaldehyde off-gassing from adhesives or engineered wood may be the culprit.
Are people with chemical sensitivities more affected by furniture glue?
Yes, people with multiple chemical sensitivity (MCS) or environmental sensitivities often react strongly to adhesive VOCs at levels that don't bother others. Even low concentrations of formaldehyde, toluene, or other solvents can trigger symptoms including headaches, respiratory distress, cognitive difficulties, and fatigue. For chemically sensitive individuals, choosing furniture with zero-VOC water-based adhesives or mechanical fasteners rather than glue becomes especially important. If that’s not feasible, let pieces off-gas outside before bringing them indoors, and consider pairing with an air purifier that removes VOCs.
Can adhesive exposure during pregnancy be harmful?
Yes, formaldehyde exposure during pregnancy is associated with developmental concerns. Research links formaldehyde exposure to increased risk of miscarriage, preterm birth, and low birth weight. Other solvents in adhesives like toluene are also associated with developmental effects. Pregnant individuals should avoid prolonged exposure to new furniture off-gassing, particularly furniture made with engineered wood or solvent-based adhesives. Ventilate thoroughly, consider letting new furniture off-gas in a garage or outdoor space before bringing it indoors, and choose NAF (no added formaldehyde) certified products when possible.
Can children be more sensitive to adhesive fumes?
Yes, children are more vulnerable to adhesive VOC exposure for several reasons. Their bodies are still developing, they breathe more air per pound of body weight than adults, and they spend more time close to the floor where heavier VOCs concentrate. Children also have less developed detoxification systems, meaning they can't eliminate VOCs from their bodies as efficiently as adults. Exposure to formaldehyde and other adhesive VOCs during childhood has been linked to increased asthma rates, respiratory infections, and cognitive effects.
Where are solvent-based adhesives used in home decor and furniture?
Solvent-based adhesives (including formaldehyde-based) appear in:
Cheaper furniture and budget brands
Engineered wood products (particleboard, MDF, plywood)
Some upholstered furniture (fabric to foam, foam to frame)
Mattress construction (layers glued together, especially in lower-quality mattresses)
Some area rug backing
Laminate furniture
Lower quality cabinetry and built-ins
Biocide and PFAS -Containing Adhesives
What are biocides in wallpaper paste?
Biocides (also called mildewcides, fungicides, or antimicrobials) are chemicals that kill organisms—including mold, mildew, bacteria, and fungi. They're added to certain adhesives, most often wallpaper, to prevent mold growth.
Why does wallpaper paste contain biocides?
Biocides are added to wallpaper paste used with non-breathable wallpapers like PVC or vinyl. When you install non-breathable wallpaper, it can trap moisture between the wall and the wallpaper surface, creating conditions that promote mold and mildew growth. Biocides help prevent this growth.
Are biocides in wallpaper paste toxic?
Yes, biocides are considered priority chemicals to avoid. They disrupt hormone function and are associated with developmental and reproductive effects, allergen sensitivity, and antibiotic resistance. While they serve a functional purpose in preventing mold, the health trade-offs are significant.
Can I use wallpaper paste without biocides?
Yes, if you're using breathable, natural wallpapers (like paper-based or natural fabric wallcoverings), you can use natural wheat paste, potato starch paste, or flour paste that contains no biocides. These natural pastes work well with breathable wallpapers that allow moisture to pass through, eliminating the mold risk that biocides are meant to address.
What wallpaper paste is safest?
The safest wallpaper paste options are natural wheat paste or potato starch paste used with breathable, natural wallpapers. Peel-and-stick wallpapers with EVA adhesive backing are also a relatively safe option. Avoid wallpaper pastes that list "mildewcide," "fungicide," or "antimicrobial" in the ingredients, especially if you're using PVC or vinyl wallpaper.
Where do PFAS-containing adhesives show up in the home?
PFAS (per- and polyfluoroalkyl substances) are sometimes added to adhesives to provide water resistance, oil resistance, and durability in specialty adhesives used for flooring and carpeting. Carpet backing adhesives and some waterproof laminate flooring adhesives are more likely to contain PFAS than standard wood furniture glues. The presence of PFAS in adhesives is concerning because these "forever chemicals" don't break down in the environment or in your body, and they're linked to immune system suppression, thyroid disruption, increased cholesterol, and certain cancers.
How can I avoid PFAS in home furnishing adhesives?
Avoiding PFAS in adhesives requires asking brands directly, as most products don't disclose PFAS content on labels.
Look for carpets and area rugs that specifically advertise "PFAS-free" construction. Home Depot started phasing out PFAS from their carpets and rugs in 2019, but that process is still ongoing, so you’d have to ask about each specific product.
While PFAS are less commonly used in indoor furniture glue, you can still choose solid wood furniture with mechanical fasteners rather than glued laminate or engineered wood products.
Some certifications like OEKO-TEX Standard 100 for textiles test for certain PFAS compounds, though comprehensive PFAS testing in adhesives remains limited.
Surprising Places Adhesives Show Up in Your Home
What furniture contains glue?
Adhesives appear in far more home furnishings than most people realize. Beyond obvious applications like wood furniture assembly, glues are hidden throughout your home in products you interact with daily.
Do mattresses contain glue?
Yes, most standard mattresses contain adhesives. Glue holds layers of foam together, bonds fabric coverings to foam, and attaches foam layers to the support core (springs or dense foam base). The type of adhesive varies dramatically—high-quality mattresses typically use water-based adhesives, organic mattresses use liquid organic latex or no adhesives (stitching only), while budget mattresses often use solvent-based or formaldehyde-based glues. This is one reason mattresses can off-gas intensely when new— it’s not just the foam. The organic mattresses I rate and rank partly on whether they use adhesives between layers are listed on my Non-Toxic Mattresses page.
Are there adhesives in area rugs?
Yes, most area rugs use adhesive to attach the backing material to the carpet fibers. This backing adhesive can be natural latex (better option) or synthetic adhesives that may contain VOCs. The backing prevents the rug from stretching and helps it lie flat, but the adhesive used varies in toxicity. Although completely organic rugs are the healthiest option, they can be expensive, so I recommend looking for area rugs made with natural fibers and without backings. I have a curated list of non-toxic area rugs here.
Is there glue in upholstered furniture?
Yes, upholstered furniture contains multiple adhesive applications. Fabric is glued to foam cushioning, foam is glued to the furniture frame, and decorative trim, welting, or buttons are often attached with adhesive rather than stitching. The type of adhesive used depends on the furniture quality and manufacturer—higher-end brands typically use water-based adhesives, while budget furniture often uses solvent-based options. I list non-toxic furniture brands that specifically use water-based glues, and many disclose exactly which brand they use, too.
Do blackout curtains contain adhesive?
Yes, many blackout curtains use adhesive to bond the blackout lining layer to the decorative fabric layer. Some blackout curtains use a foam backing that's adhered to the fabric. The adhesive type varies by manufacturer and can contribute to the chemical smell some blackout curtains have when new. Since blackout curtains are most often used in your bedroom, when your body is healing and sleeping, I recommend adhesive-free curtains, especially ones with GreenGuard GOLD and OEKO TEX certification. This is even more true for nurseries, if you’re using them for your baby’s naptime. A full list of the non-toxic blackout curtains I recommend is here.
Are there adhesives in lampshades?
Yes, lampshades typically use adhesive to attach fabric to wire frames or to bond fabric to backing material. Paper lampshades use glue to form seams and attach the paper to the frame structure.
Do picture frames contain glue?
Yes, picture frames use adhesive to attach backing boards, secure glass in place, and bond decorative elements to the frame. Canvas art uses glue to stretch and attach canvas to wooden frames.
Are decorative mirrors glued?
Yes, decorative mirrors use adhesive for mirror backing and to attach frames or decorative elements. Wall-mounted mirrors may also use construction adhesive for installation.
Do artificial plants contain adhesive?
Yes, artificial plants and floral arrangements use adhesive extensively to attach stems, leaves, and petals together. The glue type varies by manufacturer and quality level.
Do decorative pillows contain glue?
Some decorative pillows use adhesive to attach layers, apply trim, or bond decorative elements, though higher-quality pillows typically rely on stitching instead. The presence of adhesive depends on construction quality and manufacturing methods.
Are there adhesives in quilted bedding?
Yes, some quilted comforters and mattress pads use adhesive to bond layers together rather than quilting stitches. This is more common in lower-quality bedding. Higher-quality quilted bedding uses stitching to hold layers in place. Here are the non-toxic and organic comforters and duvet inserts I recommend.
I’ve listed these out individually to demonstrate a theme— sure, the glue in one time may have levels low enough to not harm you, but our house is full of products containing glue, and these exposures add up.
Making Safer Adhesive Choices
How can I tell if furniture uses toxic glues?
Most furniture doesn't disclose adhesive types, making this challenging. While most organic mattress brands will disclose what type of foam and fabric they use on their website, I almost always have to email or call them to find out what type of glues they use. I often ask what brand, but they usually say they can’t disclose that information. This is a them for all furniture! In general, indicators of lower-toxicity adhesives include:
Solid wood construction with visible joinery or mechanical fasteners
"Formaldehyde-free" or "NAF" (No Added Formaldehyde) labels
GREENGUARD Gold certification (this doesn’t mean the entire piece of furniture is non-toxic in every way, but it does limit VOC emissions, including from adhesives)
Made in USA or EU (generally stricter chemical regulations)
Strong chemical smell upon unboxing suggests high-VOC adhesives (though absence of smell doesn't guarantee safety)
When possible, ask brands directly about adhesive types used in construction.
What kinds of adhesives aren't glue-based?
Thread, nails, screws, dowels, and joinery are methods of connecting materials without relying on glue at all. Traditional joinery techniques like mortise and tenon, dovetails, or finger joints create strong connections through interlocking wood pieces. These glue-free assembly methods can often be the most natural and healthy choice for furniture.
What does "low-VOC" mean for adhesives?
"Low-VOC" indicates the product contains fewer volatile organic compounds than conventional formulations, but there's no universal standard defining the term. For meaningful comparison, look for specific VOC content listed in grams per liter (g/L) or products meeting GreenGuard, GREENGUARD Gold, or Green Seal certification standards, which set numerical VOC limits. Water-based products generally contain fewer VOCs than solvent-based alternatives.
Should I avoid all furniture with engineered wood?
Not necessarily— it’s inexpensive and accessible and there are things you can look for to reduce toxic exposures from it. Engineered wood (plywood, MDF, particleboard) made with formaldehyde-free adhesives or meeting strict emission standards can be reasonably safe. Look for:
CARB Phase 2 compliance (California Air Resources Board formaldehyde limits)
NAF (No Added Formaldehyde) certification
GREENGUARD or GREENGUARD Gold certification
TSCA Title VI compliance (federal formaldehyde emission standards)
What certifications matter for adhesive safety?
The most meaningful certifications for furniture and home products regarding adhesive safety include:
GREENGUARD Gold: Strictest VOC emission limits, including formaldehyde
CARB Phase 2: California formaldehyde emission limits for composite wood
NAF (No Added Formaldehyde): Confirms no formaldehyde in adhesives
TSCA Title VI: Federal formaldehyde emission standards
GreenGuard (standard): Basic VOC emission limits
Always remember that marketing terms like "eco-friendly" or "green" deserve skepticism without supporting certifications.
What questions should I ask furniture brands about glue?
When shopping for furniture, ask:
What types of adhesives are used in construction— water-based or solvent based? What brands do you use? Are they verified zero-VOC or low VOC and do they have GreenGuard certification?
Does the furniture contain formaldehyde-based glues?
Is the engineered wood NAF (no added formaldehyde) or CARB Phase 2 compliant?
How long should I expect off-gassing to last?
What furniture glue is safest?
The safest furniture adhesive options are:
No glue (mechanical fasteners like screws, nails, dowels, or traditional joinery)
Natural adhesives (hide glue for appropriate applications, though this is very rare outside of vintage furniture!)
Zero-VOC water-based glues and EVA adhesives
Avoid solvent-based adhesives and formaldehyde-containing glues whenever possible.
