Clean, crisp lines and plenty of attitude. If that’s how you take your space-saving chairs then Ufuk Keskin’s Sheetseat will be a must for you. Made from a single sheet of thin plywood, this mighty-morphing bum rest begs for your attention if not your behind. A prime example of an object that fools you by looking like it’ll be one thing and then proceeds to be quite another.

Update: We missed a fact on this one. Dammit. We failed to give Efecem Kutuk, co designer of the Sheetseat, his due recognition. Our apologies.
