Like many new products (new car smell anyone?), mattresses that come in a box have a scent which generally dissipates quickly after unboxing and removing packaging, though it can sometimes take up to a week or more to fully disappear.
If you notice a scent, rest assured that Koala mattress foam is made without formaldehyde, are low VOC (Volatile Organic Compounds), and meet CertiPUR-US® standards for content, emissions, and durability, and are analysed by independent, accredited testing laboratories.
Allowing the mattress to breathe in a well-ventilated space (like open windows, ceiling fan, door open) or vacuuming the mattress on a low setting helps draw out and remove this scent. We know this isn’t always practical (especially in winter!), so if you don’t, just be prepared for the scent to seem stronger or linger for a while longer
