I've ordered two Twin XL mattresses.One of them has a damaged memory foam layer.
It's two inches thick on one side and just a half inch on the other side, along the long side of the mattress. Basically it's lopsided, giving a slanting surface when you lay on it. The mattress is useless. Of course it's a "no return" type order.
Don't buy from this company or anything from GroupOn what is a "Final Sale" item, because they will send you junk. I learned the hard way. I do not recommend either companies or the product to anyone anytime.
It was a discounted item for a reason.Stay away.
