Synchronised Tilting

An ergonomically engineered mechanism allows the seat and backrest to tilt at different angles, moving in harmony with the body’s motion to deliver greater comfort.

S-curve Backrest Design

The back plate is designed in an S shape, which is the natural shape of the spine, to properly distribute the weight and support the back naturally.

Adjustable or Fixed Armrests

The adjustable armrests allow changes in height, angle, and forward/backward positioning, ensuring a natural alignment from the elbows to the shoulders for added comfort. Soft-touch padding enhances usability.

Adjustable Lumbar Support (Optional)

The upgraded lumbar support offers both height and depth adjustments to provide stable seating comfort. It gently supports the lower back without discomfort, ensuring comfort for all users.
