I ordered the Full size for my pull out couch, the problem was, it was to narrow. I called Wayfair to exchange it for a Queen size and they do not take them back for any reason!! I didn't want my money back, I just wanted the right size, and I was even willing to pay to return it myself. Nope your stuck-buyer beware!
They gave me a $37.00 return because they said the price had come down, which was appreciated but I an still stuck with a mattress that is too small.
