I would take my review with a grain of salt. I have never had a memory foam anything before, and was used to much lower quality box springs and futon beds. I did my research however and this bed met the specifications I wanted. Low cost, light weight, good user rating, and I did want to try out memory foam.-----Since the mattress is not 100% memory foam it will only contour so far against your body. If you stand on it, it will contour almost to the ground with about 2 inches of thickness between you and the base support. I still cannot feel the base support though so that is great. If laying on it, it feels very firm. I liked this because even though it feels firm it still contours to your body. Laying on my back I feel like I am laying on a very firm level board without the worry of certain 'parts' of my body raising my spine up in unusual ways.-----I do however sleep on my side and can notice it feel more resistant to the extra weight, which leaves me feeling uneven. I find myself actually sleeping on my side/stomach and sleeping peacefully. I believe if it was closer to 60% memory foam instead of the 1.5-2 inches of memory foam topper I would be sleeping on my side a lot easier. But those get real high in price based on what I can see, so this is very forgivable in my eyes.-----In short, great value for a firm mattress for a back sleeper. If your like me and plan to put this on top of a loft bed one day, I think you would be hard pressed to find another mattress with such a great value, quality, and low weight. I am glad I got the 8 inch mattress versus the 6 inch.-----P.S. it took my mattress 12 hours to go from 6 inches to closer to 7, and after the full 72 hours it's closer to 8 inches (or rather it probably is, but it is hard to measure from dead center above and below at the same time.) I think the review that says it's a light 6 inch mattress did not give it any time to expand beyond it's initial form. Also there was no smell with mine.
