I have recently bought a pillow top mattress, but I underestimated how FIRM it would sleep once I got it home. I found that I was waking up with stiff shoulders and a stiff back upon occasion. While I still need the support of a firmer mattress, I needed more SOFTNESS. I bought this mattress topper based on customer reviews alone off the overstock site, and feel it's my turn to leave mine. This mattress topper is EXACTLY what I needed to make my bed feel like the most luxurious softest bed ever! It feels like I'm sleeping in an expensive bed when I'm not! I sink into it with a grateful sigh EVERY night after work now, I sleep hard and better than I did before purchasing it. My daughter wouldn't LEAVE my bed the first night we crawled into it to watch a movie! What's nice about this purchase is the zipped up cover for it. The fabric is soft and sturdy, and it has elastic corners to tuck it onto your bed like fitted sheets so the mattress topper won't displace or shift off the bed! How wonderful is that!! Some people report a smell to it for a while once removing it from the packaging, I did not notice this at all. It does NOT sleep hot, it's cool and comfortable, and wonderful. I highly recommend purchasing this item if you feel your bed is lacking the comfort factor or it no longer feels as good as it used to. trust me, you won't be sorry!
