***We cut all our foam on a computerized CNC machine. Also when we cut a quantity of foam with the same dimensions they are cut at the same time out of a single block of foam. Each cut is recorded by the computer using your order # for tracking purposes. Our foam is shrunk down to save on shipping cost. Please open as soon as you receive it for at least 24 hours to avoid malformation to the foam. To get the air back into the foam you sometimes need to shake the foam like a sheet, or if you have access to a steam machine; apply a minimum amount of steam. This will restore you foam to the proper dimensions. If you feel the measurements are incorrect when you receive it, you are welcome to return the foam for inspection. If at that time we find that our cutting is at fault we will refund your return shipping and ship you new foam. Your satisfaction is very important to us.
