Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The molded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
