TRIUMPHKEY Gaming Chair, Ergonomic Office Chair with Footrest Headrest, Adjustable Computer Lumbar Support, Spring Cushion, Synchronized Armrests, Max 200KG, Obsidian Black

【Wide & Plush – All‑day Comfort】Sink into the extra‑wide 52cm seat with skin‑friendly velvet, high‑density foam, and a built‑in spring pack. It feels cloud‑like without sagging, while breathable velvet dissipates heat quickly. Generous enough for cross‑legged sitting – ideal for long work, gaming, or study sessions. 【Ergonomic Design – Engineered for Pain‑Free Sitting】The detachable headrest and the lumbar support (with adjustable knob) fill the natural gap between your back and the chair. Turn the knob to fine‑tune the support angle, relieving waist pressure and promoting a healthy spine – perfect for late‑night gaming or overtime work. 【Angle & Height Adjustable – Personalise Your Relaxation】Recline the backrest smoothly from 90° to 135° (lockable at any angle), and adjust overall seat height between 43cm and 55cm, suitable for users 150–200cm tall. The built‑in footrest lets you stretch out. Use the separate controls to find your ideal position – whether upright, laid‑back, or napping. 【Breathable | Class 4 Lift | Heavy‑Duty Base | Silent Casters】Breathable velvet keeps you cool. TÜV‑certified Class 4 gas lift supports up to 200kg. The reinforced 5‑star base provides rock‑solid stability, and silent PU casters glide smoothly without scratching floors. 【Versatile for Gaming, Work & Relaxation】Obsidian black with striped stitching fits gaming rooms, offices, studies, or bedrooms. Assembly takes 10 minutes with clear manual and no extra tools. TRIUMPHKEY stands behind every chair with a focus on your long‑term experience.
