You get a couch, desk, or bed frame, and right away you notice a strong chemical smell in your room. That smell usually comes from your furniture off-gassing, which happens when new materials release chemicals into the air at home. The process is called off-gassing, and furniture is a common source. Those chemicals come from materials like foam, glue, and the finishes used to build the piece.

In this article, we’ll explain furniture off-gassing and how understanding it helps you make better choices for your home and improve indoor air quality.

What is off-gassing in furniture?

Off-gassing is the emission of volatile organic compounds from furniture. Volatile Organic Compounds are usually referred to as VOCs.

Many new furniture pieces release these VOCs at room temperature because of the materials they’re made from.

Along with VOCs found in furniture, there is also another type known as Semi-Volatile Organic Compounds (SVOCs). The difference is that SVOCs take much longer than VOCs to evaporate and may continue to do so throughout the product’s lifetime.

The smell we associate with newly purchased furniture is usually from off-gassing. The sources of these VOCs include glues, synthetic foams, laminates, stains, paints, and any finishing processes applied to new furniture.

One compound has been widely associated with furniture off-gassing: formaldehyde. It’s present primarily in pressed wood products because the adhesives used to make them are resin-based.

Why does new furniture smell so strong?

VOC emissions are usually highest within the first 48-72 hours after unboxing a piece. While it sits wrapped during transit, those chemicals build up inside the packaging, so opening the box releases them into the room.

Temperature is another factor, since higher temperatures can increase emissions and lead to a stronger odor. Energy-efficient homes can make this worse because they ventilate less by design, so the smell may take days or even weeks to clear.

Which furniture off-gasses the most?

High off-gassing: MDF, particle board, synthetic foam

Furniture built from these is more likely to release VOCs, because the materials rely on adhesives and resins that boost durability and cut production costs. Pressed wood is among the most common sources thanks to its formaldehyde-based adhesives.

Low or no off-gassing: solid wood, metal, glass

Wooden furniture with natural or water-based finishes emits fewer VOCs than engineered wood. Metal and glass are low emitters because they’re inert and contain none of the adhesives, resins, or foams that release VOCs.

You can see the same move toward healthier materials in the 2026 home renovation trends, where homeowners are favoring low-emission woods, metal, and glass over engineered products.

Memory foam mattresses and carpets

Memory foam mattresses and carpets are other major contributors, especially when brand new. Memory foam has synthetic components that off-gas in the first few days, and carpets use glues and backings, sometimes plus stain-resistant treatments, that add to emissions.

Is off-gassing from furniture harmful?

Normal exposure to VOCs at home poses little threat to most adults. Still, VOCs from furniture can cause temporary effects, especially without good ventilation: headaches, eye irritation, dizziness, nausea, and throat irritation.

The absence of odor doesn’t mean the air is clear. Many VOCs have no scent, and emissions can persist long after the smell has gone.

The EPA has determined that formaldehyde, which is common in plywood and pressed wood products, is a known human carcinogen. Prolonged exposure to indoor VOC pollution may cause respiratory problems, and some VOCs are linked to liver, kidney, or nervous-system effects at high, prolonged exposure.

More sensitive groups include children, older people, pregnant women, and people with asthma. Babies and young children are the most affected, since their respiratory and immune systems are still developing, and nursery pieces like cribs, changing tables, and drawers can all off-gas. Good ventilation and low-emission furniture in kids’ rooms is well worth it.

Keep in mind that VOC levels vary a lot from one material to the next. Ventilation affects how much you actually breathe in, and higher-quality furniture releases less than cheaper pieces.

How long does furniture off-gassing last?

Most furniture off-gasses hardest for a few days and tapers off over a few weeks. Lower-quality pieces, and some building materials like certain flooring or insulation, can keep emitting at low levels for months. Temperature and humidity both affect the timeline.

Simple ways to reduce off-gassing at home

  • Open windows and doors regularly so fresh air circulates and VOCs clear faster.
  • Remove packaging from new furniture immediately, since pieces release the most VOCs when first unwrapped.
  • Air out new furniture before use, ideally in a garage or covered patio. This is one of the most effective early steps, especially combined with ventilation, humidity control, and other safe methods for reducing off-gassing faster.
  • Higher temperatures speed up VOC release, so keep the indoor temperature moderate. Maintain indoor humidity between 30% and 50% to help reduce emissions.
  • Choose low-VOC furniture and home products wherever you can.
  • Run an air purifier with an activated carbon filter to capture odors and some off-gassing chemicals.
  • Add indoor plants as a supplementary boost to air quality, and clean and dust regularly to limit buildup.

How to choose low-off-gassing furniture

Look for trusted certifications like GREENGUARD Gold, CARB compliance, or FSC certification, which independently verify lower emissions and responsible manufacturing. 

Choose solid wood where you can, since it uses fewer adhesives and synthetics than particleboard, MDF, or plywood. 

Avoid pieces heavy on glue and resin, favor low-VOC finishes like water-based stains and sealants, and ask manufacturers about emission testing and materials before you buy. 

It’s also worth checking whether a brand openly prioritizes sustainable, low-emission production.

FAQs

What is the difference between off-gassing and outgassing? Off-gassing usually refers to chemicals released from everyday products indoors. Outgassing is the broader scientific term for gas release from any material. Both describe the same basic process.

Do flame retardants in upholstered furniture off-gas? Yes, some release slowly into indoor air over time, depending on the chemical used. Good ventilation helps reduce exposure.

Does solid pine furniture off-gas? Yes, but usually far less than engineered wood, since it has fewer synthetic glues. Any smell tends to fade faster.

Can deliberately heating a room speed up off-gassing? Yes, warmth increases chemical release, which can make the smell stronger at first, so ventilation matters if you use heat.

Can furniture be sealed to reduce off-gassing? Sealing surfaces can lower emissions, though it may not stop them completely.

Does off-gassing affect pets? Yes, pets can be sensitive to VOCs and may sneeze or show irritation. Good airflow helps keep them safer.

Conclusion

Off-gassing is a normal part of bringing new furniture home. What matters is knowing what it is and how to limit it. Choosing better materials, keeping rooms ventilated, and following a few simple steps will keep indoor VOCs from building up, and you don’t have to give up new furniture to do it.
