We had company coming and knew the original mattress for our pull out sofa would not give them a good night's sleep. I saw this mattress on wayfair and thought it would be a good idea to try. The mattress was delivered on the anticipated date. I opened it up to let it get its form. It did not have nearly the odor that most memory foam mattresses have at first. Our company gave it two thumbs up! This memory foam mattress was the perfect solution to the dreaded pull out sofa problem!
