Better Support Seat Cushion – Built to Last: 55D high-density foam resists collapse. Too soft cushions feel cozy at first but sag within months. Ours is deliberately supportive – it holds your posture, resists sinking, and prevents the "numb bottom". Backed by BS EN 1335, BIFMA X5.1, and a TÜV‑tested Class 4 gas lift. Built to last, ensure years of comfortable use, protecting your posture and investment. Adjustable Seat Depth: Our 5-position sliding seat (1.97"/5cm travel, instant lock) adapts to your leg length – a feature rare in this price range. Whether you’re 5‘4“ or 6’0”, you can finally rest your whole thigh on the cushion, eliminating dangling legs, knee pressure, and the numbness that comes after 8 hours of working. Most computer chairs ignore leg health. We don’t. Ergonomic 3-point Support: Aligns head, back, and lumbar for natural curve. The lumbar support adjusts 2.36" vertically and 0.8" depth to fill the gap, while breathable mesh keeps you cool.Your productivity partner for remote work & long coding sessions 8+ hours of focused comfort.Tusted by remote professionals, programmers, and designers. Tailored Fit for Your Body Type: Designed for users within 5‘4“ – 6’0” and under 220 lbs. Compared to one‑size‑fits‑all ergonomic chairs, EC200 delivers up to 30% better body contouring within this range. For the best fit, we recommend this range.
