I've had this topper for almost 2 weeks now. I put it on a matress that's about 1 year old. The matress was firm, but the padding on top of the mattress didn't provide enough comfort to sleep in the same position for more than a few hours. I would routinely wake up with either a sore spot or because my arm fell asleep. I can sleep in pretty much any position throughout the night now and not have any aches. The topper releives all of the pressure points that existed with just my mattress. It is a little warmer, so I'm not sure how well that will work in the summer. I'm very happy with the purchase, especially with how well memory foam products are priced on Overstock.com.
