Does The O Mattress™ have an odour when first opened?

We use high-grade materials that do not have chemical off-gassing. They typically have very little to no odour.  Our premium quality foams, specifically our OmniFoundation™ Compression Foam, OmniEvolution™ Luxury Foam, OmniCool™ Cooling Gel Memory Foam do not contain any harmful chemicals, heavy metals or have any impact on air quality.

Should you smell a faint odour it will dissipate within a few hours.
