Welcome to Melltorp's official website!
One of the most common questions from new mattress buyers is: “Why does my new mattress smell?” Melltorp’s recent news feature Do you want to dry the new m… highlights common concerns about off-gassing and moisture when a mattress first arrives.
New mattresses — especially those made with memory foam or high-performance materials — can emit a mild odor when first unpacked. This is often from volatile organic compounds (VOCs) released by foams and adhesives.
Air it out: Set up the mattress in a well-ventilated room for 24–48 hours.
Open windows: Fresh air exchange speeds up off-gassing.
Avoid enclosed spaces: Don’t keep the mattress in a sealed room before use.
Use breathable bedding: Natural fibers like cotton help moisture dissipate.
Moisture buildup can lead to odors or reduced comfort. Choosing a mattress with moisture-wicking fabrics or adding a breathable mattress protector can maintain comfort and hygiene.
Practical advice: If you notice persistent smell or moisture, consider reaching out to the brand’s customer service for care guidance — many manufacturers include care tips specific to their materials.
