I did much research and read the reviews from many sites before making the decision to buy this mattress topper. So far, I'm very happy with this purchase. I've only had it about a week now and every day I enjoy it more and more. It truly has made a tremendous difference with my extremely uncomfortable firm mattress. I really have been sleeping better too. I hope in a few months I still feel the same way. I agree with the positive reviews and would highly recommended this particular topper to anyone. It really makes a world of difference.
