This was a horrible experience. I've had many mattress toppers throughout the years and finally took the leap and ordered the cloud topper. First, the topper cover came bunched up with glue spilled on it, apparently to attach the labels, and I was told just to wash it. I haven't had a decent nights sleep since I bought it. The sheets don't stay on, it's at least 3" too narrow, and it slides off the mattress. My back pain is worse than ever from twisting around in the middle of the night trying not to slide off the bed. Like many others here, I did not know that the topper was excluded from returns. I definitely wouldn't recommend it.
