This mattress topper is great! When we first unpacked it, it was hard to believe that it would spring back to be the size we ordered. But after a few hours it was perfectly smooth, no folds and fit the mattress perfectly! When you lay on it, it is like sleeping on a cloud. My kids are so excited about the comfort it provides. And, the cool gel makes it cooler to sleep on. It is like having a new mattress. Definitely worth the cost. Try it, you will not be disappointed.
