Basically you can send these guys your skateboard and you get sent back a bench.
Here is the quote from the etsy page regarding the skateboard bench:
Send us your old skateboard decks and we will build you a Custom Deckbench using your broken boards!
The new and improved deckbench is expertly crafted from 100% reclaimed and recycled broken skateboards. Like the deckstool, the legs of the deckbench are attached to the long, popsicle-shaped seat using skateboard trucks. Two steel support beams running the length keep this baby rock solid, so you can bring a friend...or two.
