I would give 5 stars but unfamiliar with foam mattresses. I was very pleasantly surprised by the price and the speed at which it was delivered...just 2 days as promised! It fit my sofa bed perfectly and is so much more comfortable than the original coil spring mattress the sofa came with. My biggest hope is that it will last longer than the original one which was under two years old. My sofa bed is used nightly for my 9 year old grandson. He is sooo happy and I can tell by his position in the morning that he is sleeping more peacefully and more comfortably. This is my first experience with Wayfair and I will be happy to use this site again. I am glad it was recommended to me by a friend.
