I got this for my mom since she's got a bed that literally is uneven and she complains that her back hurts.  I pulled it out of the box thinking no way in heck this will work but it totally does!!  You have to let it expand after pulling it out of the box and taking the plastic wrap off.. it literally almost doubled in size and was so comfy I wanted to sleep on it all night lol
I'm going to get one for my queen bed next!! This has a very nice cover too. 
I'll recommend this to my family and friends looking for a nice thin but comfy top for their mattresses.  I really love the quality and the feel of this and would be happy to recommend this!!
