Gewa Floor Protection Universal

I much prefer this pin stop than the ones that that attach to the chair with straps.

This one you just plonk down on the floor and find the right hole for the particular chair you're sitting on. The ones that attach to the chair with straps need constant adjusting for every different chair you use it with.

Only criticism is that because it's a long piece of wood folded in half, it's not quite as portable as the strap kind.

But it's still my favourite pin stop.
