Cooler Master Caliber R2C Ergonomic Gaming Chair

The Cooler Master Caliber R2C is designed for gamers and professionals who spend extended hours seated and want to stay comfortable without overheating. Its standout feature is Cool-In Technology, a breathable fabric integrated into key contact areas of the chair that actively dissipates body heat — addressing one of the most common complaints about PU leather seating. Combined with an adjustable neck cushion and lumbar support, the R2C encourages proper spinal alignment while keeping you cool throughout the day.

Built on a sturdy metal base with five competition-grade casters, the chair rolls smoothly on hard floors and carpet alike while supporting up to 330 lbs. The 90-to-180-degree recline range lets you sit upright for focused work or lay fully flat for a quick break, and the 2D adjustable armrests accommodate different arm positions for typing or gaming. While it may lack some of the premium adjustability found on higher-tier chairs, the Caliber R2C delivers a well-rounded package of ergonomic features and thermal comfort at a competitive price point.
