Yes, as with all such mattresses, there is an initial memory foam odour on opening the packaging for the first time. While some people find this unpleasant, it is entirely safe, normal and to be expected. It is also amplified to some extent with the vacuum-sealed packaging, which is air-tight. The odour naturally dissipates when the mattress is exposed to air and, depending on the ventilation of the room, usually dissipates significantly during the mattress recovery period (four hours). If required, the mattress outer cover can be removed and machine-washed prior to use.
All Ergoflex mattresses are manufactured to UK BS5852 and BS7177 safety standards and have Certi-Pur and OKEO-TEX 100 certification for complete peace of mind.
