Rating this was hard for me. The good- it is comfortable. Especially if you like a soft topper. You sink right into this. I am very happy with the comfort. The bad- I don't think the quality is that good. If you grab ahold of it to move it too hard it will rip pieces off of it. I guess you could say its somewhat fragile, which I wasn't expecting. So, that being said, I am also concerned with how long this will last without smashing down flat and becoming useless. It doesn't seem like much more than a piece of soft foam to me. I would not label this memory foam, it is mostly just a piece of 4" soft foam. Don't confuse this with a Tempurpedic type material, cause I owned a Tempurpedic and this is nothing close to that material. If you want to add softness to your bed, and don't mind the price, I would say buy it, it will add comfort. If your big on quality and are looking for a true memory foam topper, you might not be satisfied with this. I just hope its not flattened out in a few months. If it retains its shape and comfort I'll be very satisfied with it, in the mean time I will be concerned.
