I am impressed and I am very particular.  My husband and I were sleeping on a tempurpedic  mattress but on a full size bed.  We loved it and didn't want to move to a queen or king size bed because of the cost of another memory foam mattress. I bought this for the queen size mattress in the guest room and after moving to that bed  we are both so happy we are now sleeping on that bed with the topper and are sleeping much better than the full memory foam mattress.  I am thinking about getting another for the second spare bedroom,.  You wont be disappointed!!!
