Model 77 Mechanism/Materials

AeroFusion open-frame mechanism

Model 77 is built around Pelicanwork’s AeroFusion open-frame mechanism, a visible under-seat movement system designed to replace the bulky black-box mechanism found on many office chairs. The open structure gives the chair a lighter, more architectural look while making the engineering part of the visual identity.

The multi-axis synchro-tilt system helps the seat, backrest, and armrests move together as you recline. This coordinated motion helps the chair support posture changes more naturally, especially when you move between upright focus, reading, video calls, and relaxed desk work.

The full mesh seat and backrest are central to the comfort experience. Instead of trapping heat like dense foam chairs can, the breathable mesh construction helps maintain airflow through long work sessions while keeping the chair visually light.
