    • sleep on a cloud.

      This was purchases for a 73 year old who couldn't sleep through the night due to back pain. What a life changer. She was resistant to the idea- and told me she didn't want a soft mattress. I ordered SOFT- she loved it.

    • This mattress is comfortable according to my son.

      Not what I expected - it's a thick piece of foam. No fabric, no coils. That being said, my son thinks it's very comfortable and it seemed reasonably priced.

    • Very Comfortable!

      This mattress was so much better than I expected. It was very comfortable and was meant to be the mattress on a trundle bed but my daughter loved it more than the current mattress so we switched them! Highly recommend.

    • Great mattress

      We bought this to go on the trundle bed we bought through overstock because reviews recommended XL mattress (for top part). They were correct! It fit perfect.

    • Memory Foam Mattress

      I have a craftmatic bed and needed a new mattress size twin XL. This mattress is so very comfortable. I was having morning back pain, and this mattress has eliminated that pain. I did not go with the softest, but went up one step. I'm very happy with the amount of firmness in the mattress. This mattress bends well when I raise the head and foot of the bed and goes back to it's shape when the bed is horizontal again. I was able to unload the mattress from the wrapping by myself and put the mattress on the box spring, but I'm not sure I could have done this if it was a larger size mattress. It is rather heavy.

    • Nice mattress for the money

      Mattress was delivered as ordered. I got the soft which I'm glad I did because it isn't extremely soft. I got soft based on other reviews. Very comfortable. XL is 6" longer than standard which is great and regular twin sheets fit it as well.

    • Very happy

      After having slept on this bed for a few weeks now, I completely agree with all of the positive comments everyone else has made. I purposely chose this particular model because it allowed me to choose the firmness. I chose the soft and for me, it was perfect; not too soft, not too hard and oh so comfy. I was also amazed that I could actually get this mattress mailed to be in a tidy package and easily unroll it on my own and have it ready to use. I actually look forward to sleeping on it every night. It has made a difference in my mood when I wake up and it has certainly helped with all of those little aches and pains and stick neck issues. I was nervous to make an expensive purchase over the internet, but I'm really glad I did.

      We purchased this product for my husband who suffers from a disease called R.S.D. What we actually did was replace the horrible plastic mattress that was on his hospital bed with this one. My husband suffers terrible pain all day and night and the mornings are particually hard on him from staying in one position due to the need of a CPAP machine for sleep apnea. He would actually cry when first moving in the mornings but with this mattress it has helped to make his mornings just a little more bearable and we are so thankful for that. I even love to get a chance to just lay down on his bed for a short nap since I have a bad back and neck problems myself and helping him move around and pushing and getting him into and out of his wheelchair is difficult. It arrived so promptly and we had a great laugh watching it rise after unpacking it, lol.

    • Comfortable

      This mattress is very comfortable. Since I started sleeping on it I don't have near as many body aches as before and that was on a $1000 mattress. I have another bed that is needing a new mattress so I will be buying another of these

    • Good Mattress

      I ordered my mattress as "soft", but it was not quite as soft as I had expected. If you want a bed that is soft enough to "sink" into, you should probably go with something else. However, if you are on a budget and you need one with the perfect amount of support, look no further.
