Real lawn furniture

I don't know if this is cool or stupid (the line so fine sometimes, isn't it?), but here, from Gizmodo, is the grass armchair.

It's a corrugated cardboard frame that you place on your lawn, pack with soil, and sprinkle grass seed on. Before you know it, you have an immovable chair that is part of your yard.

I do know this: You will drive the person responsible for cutting the grass completely insane with a few of these!
