Campbell Chair

A custom chair build derived from Open Chair by James Tooze.

The client provided specific dimensions and design constraints for a home office chair, which I then constructed based on the construction method described for Open Chair. This provided a good basis for design, however the design soon developed quite far from the origin in that weight reduction was of utmost importance. This meant slimming down all the cross sections and building out of pine offcuts rather than ply. We also added some armrests. A significant challenge was achieving torsional rigidity between the front legs while leaving the opening entirely free for the user's legs to swing under, as requested by the client. This was eventually done by beefing up and tapering the cross member directly beneath the seat.
