Awful product, not as advertised. This was delivered in a gray plastic bag with no branding. Inside the grey bag was the foam folded in fourths and then rolled into a clear wrinkled up bag. There was no decompression after I took it out of the bag and after a couple of hours of letting it breathe on the bed, it basically remained in the original shape out of the bag. This is not orthopedic quality at all. It reminds me of the egg crate foam without the egg crate shape. Truly disappointed in the low quality and sending it back.
