Dang it I was about to post that. Haha... FOAMfotable

 

I have a pillow top but it sucks now...It was great when I got it but its sunk in where I sleep...I have to get it exchanged for Warranty...However, it has to be sunken in at a minimum of 1 1/2" - 2", which when I called them a year ago, it was almost at 1 1/2" so they didn't take it back...
