I bought this (based on the good reviews) for a guest bedroom to put on top of a memory foam mattress to 'fluff up' the look of the bed..it does accomplish that, however what stands out in my mind is how LOUD it is..not to mention it does not cover the entire bed..there is at least a 3-4" perimeter all the way around the topper that it does not cover. I haven't slept on it but i would rate the comfort of it maybe a 2 or 3. I will keep it only because I won't be sleeping on it and return shipping is not free. 

Pros: Fluffy
Cons: LOUD, not as soft/comfy as memory foam or cotton, does not cover the mattress completely
