    Verified Purchase

    We recently bought a bed that is quite high so we needed a thinner mattress to be able to get in and out of bed without a ladder. I was worried that a thin mattress would not provide the support. However, that was not the case, it is very supportive but also the comfort you expect from a foam mattress.

    Verified Purchase

    This is not comfortable because it is too thin, when we measured the thickness of it one week later it only expanded to 3.5 inches thick not what I purchased!

    Verified Purchase

    We were very surprised when this king-sized mattress arrived in such a small box. We opened it up immediately, and within a few hours it had expanded into shape. There were a few places along the edges that looked misshapen though, and we were concerned. We waited the 48 hours as recommended, and it completely straightened out! It looked terrific! We actually purchased this item to cut into cushions for our smalll RV which will reassemble into a king-size bed at night. I am not quite finished covering all the cushions, so I cannot honestly evaluate the comfort at this point. I can honestly say that I am very pleased with how it feels when we just lay down on it. We have a memory foam mattress on our home bed (I have back trouble), and I felt this would be a good choice for travel. I am looking forward to using it!
