Good purchase

I purchased this 4” mattress topper to go on top of a very uncomfortable, old, hard mattress. It has made a world of difference. I no longer wake up feeling aches and pains. The mattress topper comes conveniently already inside the cover, and expands as promised within the cover. The topper and the cover seem to be of a good quality. I would recommend this product as a good purchase.
