The ancient art of coopering, used to make classic oak barrels, is employed during the construction of the deeply curved headrest. Six billets of timber are accurately angled and then glued up in pairs before being finally glued up into a single piece. The main structural advantage of using this method of coopering is to keep a long grain to long grain glue-joint throughout the top of the chair which is the strongest bond in woodworking. This also significantly reduces wood movement.
Both the seat and headrest billets are cut from the same plank to ensure a natural grain flow and improve stability. These are the two biggest parts of the chair and act as a canvas for showcasing the beautiful grain of the wood. The sweeping headrest curve means that the backbraces can be installed to follow this curve and so fit the contours of your back more closely.
Finally, the headrest is double-drilled to create a hidden ‘inner pocket’ that accommodates the forward movement of the top of each back brace during rocking. This means the back braces move freely at all times so they flex without ‘binding up’ inside the chair.
