Specifically calibrated for users 5'4"–6'0" and under 220 lbs to deliver a proper ergonomic fit. Engineered with 3-point support: adjustable lumbar, high-tension mesh back, and 3D headrest that follows your natural spine curve, trusted by ergonomic experts for all-day comfort and focus during 8+ hour sitting sessions.
Lumbar adjusts 2.36" in height and 0.8" in depth to fill your lower-back curve and prevent slouching, staying supportive whether upright or reclined. Seat depth slides independently through 5 positions with 1.97" of travel
High-density 55D foam resists collapse and sagging through years of daily use, holding posture and preventing "bottoming out." Backed by BS EN 1335 and BIFMA X5.1 standards, paired with a TÜV-tested Class 4 gas lift for safety and long-term durability.
Four lock positions: 90° for work, 105° for reading, 120° for calls, and 130° for relaxation. A tilt tension knob lets you fine-tune recline resistance so the chair adapts to every moment of your workday — from focused typing to leaning back between tasks.
Assembles in about 20 minutes with included tools and a visual guide. The compact footprint is designed to fit bedroom corners and studio apartments, and the ProtoArc support team stands by to answer any question after purchase.
