Like anything new, the OTTY mattress may have a slight odour when first opened. After all it was tightly sealed in a plastic wrap before we delivered it! But don’t worry - this will disappear in a day or two. We recommend leaving the window open in the bedroom while the mattress is expanding for the first day or two, after which the smell should be gone. Some people love the smell and miss it when it goes!
The smell is a standard odour created by foam and memory foam products and is not harmful or toxic in any way.
