I got the 1.5" Memory Foam mattress topper for my office bed. I find my self or guest sleeping in the office every once and a while. The mattress is really old and I can't afford to replace the bed in the office.  The topper made such a difference. It felt like I was sleeping on a brand new mattress. It has been holding up a lot more than i thought it would. its quality is worth the small price it cost to make a bed more comfortable to sleep on. And it does not make my bed a lot hotter. I highly recommend getting the mattress topper.
