In the library, I was leafing through a book on Arts and Crafts furniture, and came across an armchair that was similar to the one I built, but with a back that could be adjusted to tilt at several different angles. There were two versions, both had the back attached to the seat frame with hinges. One had pegs to support the back, with three sets of holes into the sides of the armrests. The other version had a wooden bar that fit into three different sets of slots. These were very interesting, and I could incorporate either of these ideas into my chair later, but at this stage of my life I need a chair that the children can't slam down on each other, or run away with essential components.
