How Do I Get Rid Of Memory Foam Smell? (Fast Methods)

Why Does Memory Foam Smell? (Off‑Gassing Explained)

Memory foam is made from polyurethane foam with added chemicals to give it viscoelastic properties. When the pillow is manufactured, volatile organic compounds (VOCs) — primarily dimethylformamide, methylene chloride, and toluene — become trapped inside the foam cells. When you unbox a new pillow, those VOCs slowly release into the air, creating a "new foam" smell. This is called off‑gassing. The smell is harmless for most people (CertiPUR‑US certified foams have low VOC levels), but it can be unpleasant and may trigger headaches in sensitive individuals.

Fast Method #1: Air It Out (24–72 Hours)

The simplest and most effective method. Unwrap the pillow from all plastic. Place it in a well‑ventilated room with windows open. Position a fan to blow across the pillow to speed up off‑gassing. After 24 hours, the smell should be 50–70% reduced. After 48–72 hours, it should be barely noticeable. If the weather is warm and dry, you can also air it outside in the shade — never in direct sunlight, which degrades foam.

Fast Method #2: Baking Soda (12 Hours)

Baking soda neutralises odours by absorbing VOCs and moisture. Sprinkle a generous, even layer of baking soda over the entire pillow surface. Let it sit for 12 hours (or up to 24 hours for strong smells). Vacuum thoroughly using an upholstery attachment. This method is especially effective for removing the chemical smell. Repeat if needed. Do not use scented baking soda — only plain, unscented.

Fast Method #3: Activated Charcoal Bags

Place the pillow inside a large plastic bag (or seal it in a spare room) with 2–3 activated charcoal bags. Charcoal absorbs VOCs much faster than airing alone. Leave for 24–48 hours. Charcoal bags are reusable — just place them in the sun monthly to recharge. This method is excellent for strong off‑gassing or if you cannot ventilate the room.

What NOT to Do (Common Mistakes)

• Do NOT machine wash: Water destroys memory foam structure and traps moisture, leading to mould.
• Do NOT use fabric softener or dryer sheets: They coat the foam and trap VOCs.
• Do NOT use bleach or harsh chemicals: They react with foam and create toxic byproducts.
• Do NOT put in direct sunlight: UV rays break down foam cells, causing yellowing and crumbling.
• Do NOT use scented sprays or candles near the pillow: They add more chemicals without removing VOCs.

How Long Should the Smell Last Normally?

For a high‑quality, CertiPUR‑US certified memory foam pillow, off‑gassing typically lasts 3–7 days. The strongest smell occurs in the first 24–48 hours after unboxing. By day 5–7, it should be completely gone or only detectable if you put your nose directly on the pillow. Cheaper, non‑certified foams may off‑gas for several weeks.

Is Memory Foam Smell Dangerous?

For most people, no. CertiPUR‑US certified foams have been tested for VOC emissions and meet safety standards for indoor air quality. However, people with chemical sensitivities, asthma, or MCS (multiple chemical sensitivity) may experience headaches, nausea, or respiratory irritation. If you are highly sensitive, look for natural latex pillows or organic cotton pillows instead. If you already bought memory foam, air it out for 1–2 weeks before sleeping on it.

When to Return the Pillow

If the smell does not significantly decrease after 7–10 days of continuous airing and baking soda treatment, or if you have persistent symptoms (headache, dizziness, nausea) after using the pillow, return it. The pillow may be made from low‑quality, non‑certified foam with unsafe VOC levels. Buy from reputable brands that display CertiPUR‑US or Oeko‑Tex certification.
