This pad is much SMALLER than the 2'x4' stated in the description

If you read the packaging more closely, you see that it's meant to be used under a 2'x4' rug. The pad itself is smaller by over a foot in width and lacks 4" in height. Mine actually measures 20 x 34.5 inches! From the description, I expected 24 x48. Much smaller than stated.
