Who is the chair suitable for, and in what environments?

15% wider than standard chairs, with a mid-height gas lift for proper foot support. A 9 cm adjustable headrest makes it suitable for medium to larger builds. Great for gaming and workspaces.

Is the seat and backrest of the chair comfortable enough and does it provide sufficient support?

Our seat cushion combines high-density foam and springs, while the cotton-filled backrest includes an extra lumbar pillow for added comfort and firm support.

Does the chair have various adjustment functions, such as height, backrest angle, armrest height, etc.?

The chair offers a 3.1″ height adjustment, a 3.5″ adjustable headrest, and a reclining angle from 90° to 120°. The linked armrests provide support at any angle.

What to do if my office chair becomes wobbly over time?

Simply tighten the screws connecting the backrest and the seat base — this will eliminate the wobbling and restore stability.

【XXL Throne: 60cm Extra-Wide Seat】 Specifically designed for the Big & Tall, this XXL executive chair features a massive 60cm wide seat and 55cm seat depth—15% wider than standard chairs. Unlike chairs with 52–60cm heights that leave legs hanging, our optimized 49–57cm (19.3″–22.4″) range allows your feet to rest flat on the floor, eliminating under-thigh pressure. Rigorously tested to support up to 200kg（440lbs）, ensuring rock-solid stability and a true “Throne” feeling in your home or office.
【Sofa-Like Comfort: 3D Pocket Spring Matrix】Unlike ordinary foam that flattens quickly, our executive office chair features an advanced 3D Pocket Spring system for responsive, long-lasting resilience. Provides immediate “bounce back” and sofa-level comfort. It effectively relieves hip pressure during long working shifts, preventing fatigue and ensuring the cushion maintains its shape for years.
【Anti-Tipping Safety: 4mm Thickened Chassis】Built with a high-strength 4mm thickened steel chassis and a scientifically calibrated 90°-120°recline system. For Big & Tall users, this is the optimal safety balance point that keeps your center of gravity perfectly over the reinforced base. It effectively eliminates the tipping-over risk found in excessive recline angles, ensuring absolute security while you relax with the retractable footrest and synchronized linkage armrests.
【Full-Body Spinal Support: 9cm Adjustable Headrest, Lumbar Pillow & Retractable Footrest】This ergonomic office chair features a 9cm (3.5″) height-adjustable headrest that fits the natural curve of the spine, delivering customized neck support and fostering a healthy sitting posture for users of all heights. It comes with a slide-out, thickly cushioned footrest to relieve leg pressure and a detachable lumbar pillow for extra lower back support, effectively reducing strain on the entire spine.
【Sturdy, Safe & Easy to Maintain】EN12520 compliant with TÜV-certified gas lift for safety and durability. 360° rubber casters glide quietly on wood, carpet and tile without scratching wooden floors. Includes tools, instructions, 30-day returns and 3-year free parts support. For any issues, please go to “Quick Access Support” – “Your Orders” > Find the Order ID > Click “Contact Seller.
