The Cooler Master Caliber R1 is a mid-range gaming chair built around a breathable PU leather exterior, offered here in a Black/White colourway. It's rated to support users up to 150kg and reclines through a wide 90° to 180° range via a Class 4 gas-lift height adjuster, letting it go from an upright working position to nearly flat for a break. The armrests are height- and width-adjustable, the backrest measures roughly 82-83cm tall by 57cm wide, and the seat sits on a 70-72cm-diameter base rolling on 60mm casters. A head pillow and a lumbar support pillow are both included as standard for neck and lower-back support during longer sessions. Cooler Master and South African retailers list this model with a 2-year warranty, and it has a net weight of about 21.5kg. Note: this exact model has since been listed as end-of-life on Cooler Master's own site, though equivalent Black/White units remain available through South African retailers such as Wootware.
