I have tried numerous mattress toppers. All of them break down shortly after purchase leaving me with a sore back. This topper has not broke down and my back is happy!
I am a side sleeper and was waking up at night with sore hips, having to change position often and not sleeping well. My mattress is old so I thought I'd try a mattress topper. I squished several demo pads in stores, liked the temper pedicure best, and ordered this one online. I've been very happy with it, my hips are much more comfortable and I'm sleeping better. I had read online some people had trouble with sleeping too hot with foam pads, but that has not been a problem at all. I like my topper and am happy with my purchase.
I cannot say yet if I like the product. I have problems with sciatica and can only lay on one side. I find turning kind of hard so wait and see till my back improves. It almost seems too soft and makes me think of laying on a water bed. ( My daughter and son-in-law had one of those. Sorry for this comment.
This "3 inch topper" is only 2 inches thick when measured. It is advertised as medium firm; it is not. It is extremely soft. If you sleep close to the edge, DO NOT BUY THIS! You will fall/roll right off in the middle of the night because this thing doesn't have any edge support. Basically if you want to sleep on what feels like a thick comforter, this is for you. However if you are like me and have the ache and pains that come with being middle aged, don't waste your money on this. I have had this thing less than a week and I'm hurting all over.
