Ergonomic Backrest Tension & Tilt
Synchronized tilting allows the seat and backrest to recline at different angles, ensuring natural lumbar alignment and continuous ergonomic support.

B. Multi-Limited Tilt Range Adjustment Lever
Premium Mechanism
Developed over six years, the Ultimate Sync Tilt mechanism incorporates 138 precision components, delivering top-tier engineering that virtually eliminates backrest shift for seamless, natural motion.
Ultimate Sync Tilt – Movement that Fits the Body
In conventional chairs, reclining can create a gap of more than 0.6" between the backrest and the body as the hips shift forward. The T90 reduces this gap to just 0.12", enabling the backrest to move in unison with the body like a recliner, delivering exceptional comfort. A: T90 B: Previous Model * Patent No. 10-1533650

Flexible Backrest
High-comfort cushioning combining memory foam and MDI foam delivers stable seating. The backrest naturally responds to movement, reducing shoulder strain.
Forward Tilting

The seat can slide forward and backward to accommodate different body types.
Adjustable Headrest
With 2.8" height adjustment and 65° rotation, the headrest can be precisely set to reduce strain on the head and neck, ensuring lasting comfort even during extended sitting.
4D Panoramic Armrests
The 4D armrests allow fine adjustment in height, depth, angle, and pivot, helping each user find their optimal ergonomic position. Their soft elasticity distributes shoulder and arm pressure evenly, maintaining comfort during long hours. * Height adjustment: 2.8" / 7 steps, Depth adjustment: 2.0" / 5 steps * Arm pad rotation and slide: 35° inward–230° backward
Gentle Waterfall Edge

Cloud Foam Cushion
High-density Cloud Foam delivers stable comfort, while a patented scooping process contours the seat to the body’s natural shape.
Two Premium Finish Options
The double-layer mesh features two air layers that provide excellent breathability and durability, while stain- and water-resistant treatment offers superior protection against wear. The premium genuine leather finish delivers a natural texture and refined ambiance, adding a premium touch to any space.
