The pipe–joint system used in tents and outdoor gear is composed minimally according to the flow of load, separating linear members from point-based connections, and is well suited for repeated assembly and disassembly.

The seat and backrest are formed without rigid panels, using Cordura fabric inserted into the pipes. Tension generated through the relationship with the frame creates a planar surface. The pipes and joints function as the minimal structure required for this, and the assembled frame is locked with the final bolt fastening, completing a stable state with maintained tension.
