Bought this 4-in topper so that it could be cut down to a size that would fit in my camper, which is not a standard size bed. It's made a big difference in the comfort level for sleeping

So comfy and I now wake up without a backache!

Very pleased with the purchase of this Gel Foam mattress topper. It made our guest bed so much more comfortable! It completely wraps around the mattress like a deep-pocked sheet and it stays in place.

I think it's not 4 inches. The 2 pieces together are as thick as my middle finger is long and i have small hands. I thought the foam was going to be 4 inches thick with a ¼ inche or less toper. Well the Topper is ¼ inch but the foam is around 2 inches. Its my opinion this should be advertised as a 3 inch at the thickest. Other than the false advertising it is quite soft and comfortable. I don't yet know If it's cooling or not.

Arrived stained and thinner than described online.
