When I took it out of the box I looked at it and thought, this will be going back for sure. I decided to do as the instructions suggested before totally writing it off as a bad purchase. I let it sit overnight and when I checked it the next morning it was perfect. I was very surprised. It is nice and thick and it responded as most memory foam, it forms to your body. As for my arthritis, well I still feel soreness when I am on my side even with this topper but I don't think many mattress/toppers will totally eliminate that. So if you order one, don't judge it by how it looks when you take it out of the box, do as instructed and check it the next day.

Awesome!

This is a great memory foam topper. It was shipped in a Serta box and came in a Serta bag. This is quality memory foam with a little support. It takes awhile to expand so dont pull it apart. Let it expand on its own. I highly recommend!

Good quality, good feel, reasonable price

But a new good name, brand hybrid bed, which was slightly too firm and this mattress topper made it perfect. It's not too mushy. It's just right for my comfort and the whole thing is still firm but soft.
