This is exactly what i hoped for....amazingly firm but comfortable..i know that's difficult to grasp for some, but it gives great support. Currently very happy with our purchase, arrived quickly, off gassing barely noticeable (but we have had a few memory foam mattresses and the smell never bothered us too much), quickly expanded to full size and the cooling aspect is effective as well. We find a much cooler nights sleep on this mattress. We have bought ALL our mattresses from Great Offer Stock. Once we went to a mattress store with horrible results. Thanks Great Offer Stock for carrying what we feel is a great product. Will update in future if needed!
