This was a replacement mattress because the first 1 I ordered was too firm even though it said it was a pillow top...but this memory foam is even harder ...it does not feel like a medium mattress at all...I cant send it back because I won't get a full refund because I will have to pay the return, being as I already sent the first 1 back....Dont buy a mattress unless you have tested it yourself..  I have a bad back as it is and I am getting no sleep at all now exept on my settee
