New memory foam pillows sometimes arrive with a chemical smell. This odour, often called off gassing, usually fades as volatile compounds dissipate. Most are present in tiny amounts and are not harmful in normal use, but the smell can be distracting. This UK guide explains what off gassing is, how to speed it up safely, when to be cautious, and how to choose pillows with lower odour out of the box.
Neck comfort starts with pillows matched to sleep position and consistent loft.
What off gassing is
Off gassing is the release of volatile compounds from new materials. Foams and adhesives used in pillows can trap these compounds during manufacturing and packaging. When you open the bag, you notice the smell because it has nowhere else to go. It is similar to the new car smell and tends to fade quickly with airflow.
How to air a new pillow
Remove the pillow from all packaging and place it in a well ventilated room. Open a window for short periods. Do not put the pillow in direct sun for hours, which can heat foam excessively. If the pillow has a removable cover, wash the cover first. Many smells are on the fabric rather than deep in the foam. For adjustable shredded foam, spread the fill in a clean, breathable bag for a day to increase airflow, then reassemble.
How long the smell lasts
Most odours fade within a few days. Some sensitive noses notice a light smell for a week or two. If a strong odour persists beyond that, contact the brand. Quality control varies. Reputable brands replace items that do not air out normally.
Certifications and low odour choices
Look for foam that meets safety standards such as CertiPUR or OEKO TEX for textiles. These certifications limit certain chemicals and can correlate with lower odours. Latex pillows often have a different, mild rubber scent that fades quickly and may be preferable for sensitive users.
When to be cautious
If you experience headaches or irritation from new smells, air the pillow in another room until it fades. Avoid using strong perfumes to mask the scent, which can make the room feel stuffy. If you have respiratory conditions and are concerned, choose latex or fibre pillows that tend to have minimal odour out of the bag.
Care and long term freshness
Use a breathable protector and wash it regularly so sweat does not soak into the foam. Air the pillow on dry days. Avoid sealing a damp pillow in a bag or under heavy covers, which can trap smells. Replace foam that develops a stale odour even after airing, as it may be breaking down and past its best.
We highlight low odour foam and latex options in our guide to pillows for sensitive noses. Keep the bed feeling fresh with breathable sheets and a protector that washes easily.
FAQs
Is off gassing harmful?
In typical products from reputable brands, odours are low and fade quickly. If you are concerned, choose certified foams or latex and air items before use.
How do I get rid of the smell fast?
Ventilate the room, wash removable covers, and allow airflow around the pillow for a day or two. Avoid heat and direct sun.
Which pillows have the least smell?
Latex and quality fibre pillows tend to have minimal odour out of the box. Certified memory foams with breathable covers also help.
Lower‑odour foams and latex options appear in pillows for sensitive noses. Breathable bedding completes the setup with cool sheets and a quiet mattress protector.
