Bests & Worsts Reviews from Amazon

I just got this today, but I'm really impressed so far. I read hundreds of reviews on every mattress in the sub $250 range on here. I agonized for two weeks over which was more likely to fail based on the number of people with bad experiences. I ended up getting this one because I had already tried it out at a friend's place and because it's so cheap. I figure I can buy a topper for it if it's too thin. But I unpacked it this afternoon, it inflated instantly (before I could get the plastic off really), and it's already at full size after only 7.5 hours. It also barely has a smell to it. Only detectable if you put your face in it, and a t shirt on the bed is enough to cover that up. I'm going to sleep on this tonight and see how it is - will update this soon with impressions. Oh, it also doesn't seem to be overly firm or soft. I'm a 6' tall 180 pound guy and I can't feel the ground underneath (currently have it on my carpet) while laying on my side. Seems pretty comfortable and the foam rebounds quickly after being pushed in (but I can feel myself sinking in ever so slightly when lying down). Update 3/25: I did let this air out for a day just to be sure, and I slept on it last night. I didn''t want to get up this morning - the mattress is very comfortable. The memory foam is a little too thin, such that I could feel my shoulder touching the harder foam underneath. But when I got to sleep I didn't notice this at all. However, the foam being thin is totally expected and I plan to buy a high-quality memory foam topper for this to fill it out. Update 4/25: Aftertrying this out for several weeks it ended up being really disappointing. My back started aching terribly; I have never had back pain before and knew it must be from the mattress. The basefoam on this simply does not provide the support that you need. I ended up getting a full refund on this, so props to Amazon.
