    • Great for adjustable beds!

      We bought this mattress and we are quite happy with the purchase. We own an adjustable bed so having a mattress with pocketed coils is a must. But to have foam as well as the coils, shoot, you can't get a better night sleep than this. You've got the support of the coils plus the comfort of the foam. Highly recommend!

    • Great mattress and customer service! Adjustable

      First I want to thank Amanda from customer service. The wrong mattress was shipped to me by mistake. Amanda got right on it and took care of everything. My new mattress, The Nuform Affinity is awesome!! I have pressure point issues with my hips and was not able to comfortably sleep on either side. The pillow top and mattress has made it possible to sleep on both sides and my legs do not ache any more.Amanda actually called me back after it was delivered to make sure I was satisfied and the order complete. The mattress fit perfectly on my twin XL adjustable bed. My new mattress is exactly the same height as my husband's original mattress next to mine.

      We love this mattress, it is so comfortable we sleep great! It is the perfect combination of softness and support. I like that it is made in the USA and the quality is really good. We are using this with the posture loft king size adjustable base and they are perfect together. I sleep so much better now and my husband doesn't toss and turn anymore.

    • Perfect length for my 6ft Tall Son
      Verified Purchase

      I just recently moved and my son who is 6ft tall was in a full bed but his feet still hung over. His new room didn't fit a full so we went with the twin xl. The length is perfect. The mattress itself, come rolled up and a box and as soon as you cut the packaging it "inflates" itself. His mattress is very comfortable. let it sit out overnight before you use it.

      My husband loves this mattress. We have a king size split mattress bed and he chose this when he wasn't able to use the foam mattress that I prefer.

      I bought this to replace a very expensive name brand memory foam, that was just too soft and too hot for me. This one is perfect and fit right into our adjustable frame and is the same height. My husband like his old mattress, but for me, this new one is perfect for a fraction of the price! Thanks Ostock!
