Wondergel wasn't "Extremely" comfortable
This cushion isn't much more comfortable than the hard seat cushion in my truck that it was meant to soften and certainly not worth the $70-something I paid for it.  I wasn't surprised to find it marked down 2wks later in a truck stop chain for $50-something... still a ridiculous price for something that doesn't work any better than the cheap $20 cushions you see at Wal*Mart. I had high hopes when purchasing and although I was served quickly by the seller, the product doesn't meet the mark it claims to be able to achieve.
