This product offers a secure fit around the lower back, with an adjustable lumbar support design that accommodates different body types.
## '3D Lumbar Support' for a Precise Fit
The chair features a 3D structure that supports the back and waist from three directions—left, right, and center—distributing physical pressure. It is fully adjustable both vertically and horizontally.
## '4D Armrests' for Optimal Positioning
Equipped with 4D armrests, users can adjust height (8cm), depth (5.5cm), width (4cm), and angle (33°). This design helps relieve unconscious tension in the shoulders and neck.
## Ergonomic Design Features
- S-curve Backrest: Designed to follow the spine's natural curve, promoting an ideal sitting posture.
- Adjustable Headrest: Height (5cm) and angle (30°) adjustable for optimal neck support.
- 3-Stage Reclining Lock: Users can lock the backrest in three positions, ranging from upright working to relaxed lounging.
## Breathable Mesh Material
The backrest and seat are made of highly breathable mesh fabric, ensuring comfort throughout the seasons. The seat uses urethane for added cushioning, and the polyurethane casters are designed to be floor-friendly.
The product is available at Tansu no Gen's official store, Rakuten, and Yahoo! Shopping.
