I really don't know how this topper is getting any good reviews. Firstly, it's NOT even close to being 4" thick. It's 2" MAX!!! The stuffing feels just like cotton batting. It eventually compresses even thinner where you lay on it and it doe not rebound. It is soft, but not even close to as thick as it is described or pictured. Secondly, it took a very long time to ship to me - almost 2 months?? Because it is made and shipped FROM China! So not impressed with that either. I wanted to give it a chance but I wish I had just returned it because it has ended up being a huge waste of money.
