Minecraft wiki entry for Furniture, associated text: Chairs can be made similarly to sofas, but the 'sitting' area is only 1 block wide. There are many variations of the chair listed below. You could just place 1 stair block for a simple chair. You could also put 1 stair block down, and put blank signs on the side for an armchair. You could also put down 1 slab, with blank signs on the sides and the back for a cool-looking armchair.
