I am extremely satisfied after purchasing this gel memory foam mattress from wayfair.com. I purchased this mattress in October of this year after having major abdominal surgery, and I have slept comfortably every night since. I replaced my innerspring mattress with this one and would never think of sleeping on an old style innerspring mattress again. My cats even sleep on my new bed all of the time now. Thank you wayfair for selling me a quality product with prompt and friendly service.
