II. Five Core Reasons (Product Highlights)
1. 135° Recline + High Back Support → True Spinal Protection
Scientific angle: 135° is a proven “zero‑gravity” posture, reducing lumbar pressure by nearly 40% compared to upright 90° sitting.

Scientific angle: 135° is a proven “zero‑gravity” posture, reducing lumbar pressure by nearly 40% compared to upright 90° sitting.
High back design: Extends above the shoulder blades, providing continuous support for the cervical, thoracic, and lumbar spine – no more hollow lower back.
Nap ready: Recline during breaks for a quick rest – no need for a separate folding bed or lounge chair.
2. Adjustable Headrest + S‑Curve Backrest → Effectively Relieves Neck & Shoulder Stiffness
Adjustable headrest: Slides 5–8 cm vertically and tilts 15°–30° to support your head and neck, preventing forward head posture.
