I bought the Night Therapy 10 inch Pillow Top Spring Complete Mattress Set-Twin for our guestroom. Of course I had to try it out first though! I absolutely love this mattress, so much so that I purchased a queen size one for my own bedroom. The pillow top is thick and soft, but there is still a feeling of firmness from the mattress. I don't like my mattress to be too cushy, which would give me a back ache. The pillow top creates balance between the firmness of the mattress and the comfort of the pillow top. I sleep like a baby every night on this mattress. Any time guests stay over they always tell me they slept great, like they were at home. This mattress is a very good value and I highly recommend it. Comfort I have tried many mattresses in the store and this beats them all. Support It has just the right amount of firmness. I am a side sleeper mainly, but I do turn on my back sometimes and this mattress offers great support in both positions. Durability This mattress hold its firmness and doesn't wear down easily.
