How Ergonomic Design Supports You
An ergonomic chair is designed to follow the natural curve of the spine—from the cervical (neck), through the thoracic (upper back), down to the lumbar (lower back) region.
- Neck (Cervical Spine): The headrest gently cradles the neck, reducing tension from long hours of looking at screens.
- Upper Back (Thoracic Spine): The backrest encourages upright posture, taking pressure off the shoulders and upper spine.
- Lower Back (Lumbar Spine): Built-in lumbar support fits the curve of the lower back, easing stress on the discs and helping prevent back pain.

More Support Where It Matters
Compared to other chairs, Sihoo chairs offer noticeably better lower back support.
The secret lies in our ergonomic design: a W-shaped seat cushion that encourages healthy hip alignment, combined with a spine-friendly backrest that follows the natural curve of your lumbar spine.
Together, they cradle your lower back, reduce pressure, and help you sit longer—without the pain.
No matter the space, your comfort always comes first.
