I bought this mattress based upon other online reviews and the presentation video by the manufacturer.  As a large and tall man I needed something better than bargain basement matresses of my past. I'm 300lbs and 6'2" and this matress only sinks at my hips about 3" with the rest of my pressure point only dropping 1"-2". Unbaging was a new experience and watching vidoes helped get it right the first time. I experienced minimal foam smell which reminded me of new car not a chemical plant. The cover is soft yet seems to be durable and after 48 hours I'm sleeping more comfortable than I've had in a long time. So if your a big person or couple than this is it if your under 150 I'd say your taking a chance. It's about time the world took notice of the needs of big people and made them an accessible non exclusive option.
