I bought one of these toppers for each of our girls for Christmas. We put them on their beds in the morning after they opened them and they couldn't wait to try them out Christmas night! Even at ages 17, 16 and 12 years old they were excited to have this Christmas gift almost more than any other. My only problem is that they don't want to get out of bed, they love them. I just wish I could have gotten one in a queen size for my bed.
There are too many baffles, this feels akin to sleeping on a mogul ski slope. Once the baffles do wear down, there is not much padding. This forces you to move to another part and then you're fighting lumps again. In regards to the quality though, this is a well made product. The fiber was thick, and the material nice, just can get over the bumps.
Unfortunately this item arrived with a hole in it and appeared to have been previously used. It did seem to be well made and heavy. I can not comment on the comfort as it was never used by me. I can say the packaging had Serta as the manufacturer. If you manage to get one that hasn't been damaged, it seems to be a quality item. Overstock was very cooperative reguarding the return!
