I've had other fiber beds/toppers that I've paid quite a bit more for, and this is a good alternative. First of all, the polyester fiber beds are for those of us who don't like the feathers and unevenness of down (had those too). So if you're in the market for a poly fiber bed or topper the keys are the amount and evenness of the fill. This topper has substantial fill (I think 120 oz) and it is well distributed with the "baffle box" design that keeps the fill from clumping. At first it appeared and felt a bit lumpy but it evens and smooths out when used. It is soft and cushioned without swallowing you. I'm using it in a new memory foam mattress I also bought from Overstock to offset firmness and it is working well. I took a risk on buying this with no reviews so I wanted to get the ball rolling hopefully to help others. Definitely recommend. Sure, there are better ones out there but for the price this more than meets the need!
