TRALT Office Chair Ergonomic Desk Chair with Lumbar Support Black, 1

About this item
High-Resilience Molded Foam Seat – Won’t Flatten After 1 Year – Instead of budget foam that hardens and sags within months, the seat is built with high-density, high-resilience molded foam that bounces back day after day. It maintains its shape and cushioning far longer, preventing the “bottoming out” discomfort common at this price point
Adjustable Lumbar, Not a Fixed Afterthought – Unlike flimsy plastic supports that crack or lose tension, this chair features a durable lumbar mechanism that adjusts depth to match your spine’s natural curve. Genuinely relieves lower back pressure during long sitting sessions
Breathable Mesh Backrest – No Peeling, No Heat Buildup – Say goodbye to flaking faux leather. The high-tension mesh back promotes continuous airflow, keeping you cool in warm environments and eliminating the mess of peeling upholstery. Mesh holds up significantly better over time and looks professional years later
Anti-Sink BIFMA Certified Gas Cylinder – A common failure in budget chairs: the pneumatic cylinder loses pressure and slowly sinks during use. Our Class 3 BIFMA-certified gas lift is built to hold its height reliably, so your chair stays exactly where you set it—year after year. No more sudden drops or mid-work adjustments
Heavy-Duty Metal Core Base (330 lbs Capacity) – Thin plastic bases can crack under stress, especially near the cylinder hub. We use a reinforced nylon base with a metal core, providing the durability and peace of mind you need. Smooth-rolling, 360° silent casters glide across hardwood, tile, or carpet without scratching or catching
Perfectly Sized Seat for All-Day Comfort & Ideal Fit – The generously wide 19.7″ seat provides ample room without feeling restrictive, while the 17.3″ seat depth is carefully calibrated to support your thighs while leaving the recommended 2–4 finger gap behind your knees — protecting circulation and reducing pressure. The 17.7″–21.7″ seat height range comfortably fits users from approximately 5’4″ to 6’2″, allowing your feet to rest flat on the floor for proper posture
