Plain ol' chairs, couches, sofas, and similar furniture take up too much space and can be too costly, but you've gotta sit somewhere. The easy solution? Cut some holes in your floor and say that you've made an OOoo Chair.
The idea for the OOoo Chair comes from the folks at design firm Decker Yeadon. They thought that it's perfectly logical to expect people to stick their legs through holes in a floor in order to conserve space, money, and materials.
