My husband and I love the big bumps. We had the most basic sleep number bed and it was starting to be very uncomfortable! We both had all kinds of pressure points and a lot of night sweating. The topper arrived when promised. We followed the directions. The smell wasn't terrible. We only let it air out for 24 hours and that is when we discovered bliss! Have had nothing but great nights sleep since the first night. No more sweating. No more pressure points. We love it. No more pain!
