We have slept on it for the past 2 nights (I know that's not long) but so far so good. The support is great, we aren't sleeping to hot and haven't felt like we are sleeping in a hole so it has dispelled the two biggest issues we were concerned with.   We are pleased with the product, the price was very good and it shipped and arrived exactly as indicated. This was our first purchase on Wayfair and we give it two thumbs up!
