Made my hard mattress softer. I honestly love this thing it saved my 1200 mattress from being replaced. Now my husband and I no longer wake up with back pain. The fitted sheet that goes over the mattress topper is very easy to clean and lightweight. I have a 3.0 cu ft portable washer and it’s not a problem to wash.

Update four years later: It has been four years since I purchased this topper, and it is still strong. It has stretched a little, but it is intact and comfortable. The fitted sheet covering the topper and mattress is still in great shape. I did a lot of research before buying this, and I can say it is one of the best purchases I've made in my life. Your back will thank you.
