Great mattress topper! It came less than a week so that was really awesome! Definitely recommend buying a fitted sheet with deep pockets because it is so thick but totally worth it. Only reason I didn't give it 5 stars was because you can't really feel the cooling gel... But it is very "breathable". I used to sweat a lot when I slept and now I sleep so much more comfortably!! The reviews were very helpful when making a decision for buying this product
