Minecraft wiki entry for Furniture, associated text: You can also make a working chair, using a minecart, rail, stair, 2 signs, any full block, a piston, and a lever. First place a piston 2 blocks above where you want your chair to be (facing down) and place a lever on the side of it, next place a full block with a rail on it where you want your chair to be, then place a minecart on the rail and break the block below the rail, after that place a stair where the rail was, finally activate the lever, it should push the stair block into the minecart, now break the piston and lever and place signs on the sides of the chair. To make a cool desk chair you could use a Red Nether Brick Slab instead of a stair, spruce or dark oak trapdoors instead of signs and 2 more trapdoors behind the chair as the back, and a red banner on the top back trapdoor hanging into the seat (you could also make a working a couch using this method). IMPORTANT: if you touch the chair while moving, it could mess up the minecart. there are 2 ways to fix this, the first is taking apart the chair and repeating these steps, the second can also also prevent this but requires cheats, for the second one you can either enter the command: /tp @e [type=minecart,c=1] (replace this with the cordinates of the chair) facing (replace this with the cordinates 1 block to the left or right of the chair), or place a repeating command block under the chair set to 600 ticks in delay and always active with the same command as before. Ex. if your chair is at coordinates 176 85 293 and facing north then the command is: /tp @e [type=minecart,c=1] 176 85 293 facing 176 85 294(Note: the last number could be 294 or 292).
