Seats

From BackYardWiki

Since the first of our ape-like ancestors decided that crawling around on all fours wasn't for them and started walking bipedal-style, we've been looking for places to sit down. Seats provide this basic human requirement and range in their level of comfort from very comfy, wonderfully thick-stuffed sofas to a seat in a McDonald's restaurant which is one small piece of padding removed from sitting on a rusted spike.

Some seats swivel, and are called swivel chairs (for obvious reasons).
