Bought the twin mattress for my son bedroom. I am very impress with this mattress. The mattress take less than 1min to expand to it mattress frame but we did listen to the manual instructions to give 3day for mattress to complete expand. The mattress is wonderful and my son and I have sleep on this mattress for many days already. I weight 110lb and with my son this mattress provide great support. This is a 10inch twin matrress that is above average twin  mattress thickness. The medium firmness of the mattress met my expectations. The softness of the pillow top, the quality and the elegant look of this mattress is well worth the price. I wanted to buy again but item current out of stock. The only thing I did not like is the strong oder of this mattress for the first few day.
