    • So comfy
      Verified Purchase

      My husband and I both love this bed. He has back and knee problems and the support of this bed help him sleep much better and wake up without pain. I have a curvy back and hips so I need the support for my back and the softness for my hips. This bed provides both. The first few nights we slept on it, it seemed a little hard. I don't know if it has softened up over time or if we've gotten used to it, but it's great now. I recommend to anyone that has purchased this bed to give it a try for at least week because it really did seem to change over time for us.
