Extremely disappointed at the thickness (or lack of, actually). Your dimensions state 5" thick. I measured it out of the package...and it would have required TWO of them to equal 5"! Very flat - totally unlike advertised. I had too use it with a 3" piece of foam. I did not report my disappointment because the immediate use that was necessary. I have purchased from you before, and all was fine. BIG EXCEPTION with this cushion. Very unhappy. It was necessary to leave a "star" mark - so, I had to define the experience as "missing The Mark. There was no option for anything lower.
