You need support that actually tracks your spine through the day, not a flat panel you lean against. The Mirae's height-adjustable ratchet back follows your posture whether you're leaning in or stretching back. Four-lever mechanism with seat slide lets you set depth and angle to your body in two pulls. Moulded foam seat stays firm all day — no sinking by afternoon. Five-star base with 50mm hard-floor castors glides on tile, carpet, or concrete without scuffing. Rated to 160kg. AFRDI certified, BIFMA tested. 10-year warranty so it's a set-and-forget purchase
