Very fast shipping, I placed my order on Saturday and the bed arrived by Thursday. Our previous mattress was a 12” Lucid hybrid which was too firm, after about three years I began to have issues with pressure point pain and back pain so we decided it was time to try something else. This mattress is THICK, my bed frame is a platform with headboard and it just about disappeared between the mattress height and my pillows. It appears to have fully inflated within 24 hours. Without sheets and a mattress protector the bed has much more of a plush, sink in feeling however, upon adding a protector and cotton sheets it feels more medium with a bit less give (which is to be expected). Overall
