Due to Covid-19, hygiene and safety reasons, O Mattress does not accept O Mattress mattresses in return once the box has been opened. Many other companies do accept returns and resell the returned mattresses to new customers. Our policy is to always provide our customers with a 100% brand new Hybrid “O” Mattress with an industry leading 20 year warranty, which clearly shows we stand behind our product. Many thousands of Canadians love their O Mattress mattresses and prefer the comfort of an amazing mattress warranty!
