This is the best mattress topper I've ever owned. I bought a $200 queen size mattress that expands when you take it out the box. I'm just in a studio apt so I figured there's no need for me to be super fancy at this stage in my life. Well it turns out I do have a few standards and comfort is one. I slept on this mattress topper for the first time last night and I imagine this is what people mean when they refer to sleeping on a cloud.
