These are essentially some huge blocks of high density foam. They just happen to have a vinyl covering that trucks have been using as a cushion. Breaking down the price of high density foam by volume, this stuff goes for $.90 per board foot (1"x12"x12") online, so we're cutting that price in half, making these HUGE blocks $.45/ board foot. The pieces are 1'x2'x9'6" and 1'x2'x7'9". We have 2 of the 9'6" pieces and those are $100. We have 4 of the 7'9" pieces and those are $85 a piece.
