Detailed Review

Assembly demands patience: multiple adjustment mechanisms, hydraulic piston alignment, numbered hardware bags—45 minutes with two people recommended. Light grey Denmark mesh immediately professionalizes workspaces; 136.5 cm height cradles occipital perfectly.

Suspended seat cushion revolutionizes comfort: wave spring memory foam bounces without bottoming, 5cm depth slider accommodates thigh lengths precisely. Twistable backrest lumbar adjusts height/tension independently—thoracic/lumbar support follows spine curvature dynamically. 4D armrests perfection: rotated for side work, narrowed under desk, raised typing, depth-matched elbows.

Tilt system excellence: 107° productivity lock, 123° relaxed reading, 132° brief recline—tension knob calibrates resistance perfectly. Aluminum seat pan distributes weight evenly; 5 premium casters glide silently. Extended testing confirmed breathability (cool at 85°F), adjustments smooth, foam resilient. Minor: vacuum mesh weekly; crank lumbar initially stiffens.
