I just received my gel memory foam mattress topper and I gave it one less star because I paid for a 5.5 topper and received a 4 inch topper with a m atress pad that doesn't add up to anything so I actually paid for a 4" topper..decieving a bit..all together with the pad they give, it might equal 4 and 1/4"..soft though..not going to send back because way to much trouble..also comes all crunched up but not to worry it warms up and comes to form.
