Query: Eggcrate Wheelchair Cushion With Back 18" x 32" x 3"

As was stated by another buyer this is very deceptive. They are not remotely the same as two I bought a few months ago, Duro-Med Convoluted Foam Chair Pads with Seat, Blue, here on Amazon and was VERY pleased; they were shipped by Global Surgical Supply. http://www.amazon.com/gp/product/B000HM34LS/ref=oh_details_o03_s00_i00 I was very pleased with those but needed another seat and bought from this company because the picture seat shown appeared identical. However, It is NOT the same seat at all. Duro-Med's seat has an extra 3-4 inches of dense foam under the sitting egg crate area (which does appear in the picture shown here too, but does NOT exist on the real product shipped. This seat does NOT have the additional 3-4 inch padding under the sitting layer at all and does appear to be cut from the cheaper thin egg crate top layer only.
