The idea that a sheet of wood that measures 3/4” thickness can become a usable chair blows my mind slightly, but that’s exactly what the Sheetseat by Ufuk Keskin is.
The Sheetseat looks like a piece of cardboard, but is in fact plywood that is cut so that it can go from a perfectly flat piece of wood to an unfolded chair. This would definitely make for easy storage and transport, as you could stack them up without issue. Take a look at this great space saving idea.
