I absolutely love this mattress memory foam topper. I have arthritis and spine inflammation that makes sleeping very painful, and this topper is really helpful. It is so comfortable, it literally feels like you are sleeping on a cloud. It comes in a roll in a box, and once you open the package it fluffed up easily in minutes. It’s light and easy to put on the bed, and has made my normal mattress so much more comfortable. Awesome product, definitely worth a try!
