This mattress topper is ok. Maybe it's a little bit too soft, and may not be good for the back. And because of the packing, it is permanently slightly folded in the middle even after its complete expansion. But I would keep it. The quality does not match the price.
I have a memory foam for my cal king, and it's a 2 inch that I paid over $$$ for. It feels great. These, the ones I'm buying from Overstock, they feel just like a normal sponge.. not much memory effect... My son has used it for few weeks now, and he wants it off.. something is not right.. and I don't know what..
This mattress topper is sooooooo soft and comfortable. My spouse and I are finally getting some restful sleep. There is NO oder when we received it and even though it was cold, it expanded to its full size. Thanks for a wonderful product!
