  • Sleep Sync 12 inch King size mattress, great bed!

    This is our first night sleeping on this mattress, it's very firm and supports every part of your body. My husband has back problems and so far he is in love with it! When we first opened it out of the box it's a good thing we already had it in our bedroom, as it began to open up and rise VERY quickly, and it is heavy so you might want to make sure that you open it in your bedroom so you don't have much moving to do. There was no smell, as we had been told memory foam mattresses had a smell, and it rose quickly and was ready to lay on in minutes. Buying it through was a great deal as we saved hundreds of dollars. Very happy with our purchase.
