I have purchased many mattresses online before and it's always been like a roll of the dice on what you get. This time was very different, since i have made many purchases from Wayfair before i knew there is no risk buying from them. This mattress being a Wayfair brand product means that they stand behind the product and will do what it takes to make things right. So no risk. The mattress is like sleeping on air, yet it is just the right amount of firmness so you wake without any stiffness. Wayfair is the way to shop online.
