Cooler Master Caliber R3C Gaming Chair with Cool-In Technology — Black

The Cooler Master Caliber R3C is a premium gaming chair built around proprietary Cool-In Technology. The formaldehyde-free, cat-scratch-proof, and dust-repellent Cool-In fabric features a perforated breathable design engineered to feel 1–2 °C cooler than standard upholstery, reducing heat buildup during extended gaming sessions.

Beneath the fabric, a steel frame and base provide a robust structural foundation, while memory foam filling in both the seat and the included headrest and lumbar pillows ensures lasting ergonomic comfort. A Class 4 gas lift delivers smooth, reliable seat-height adjustment.

With a recline range of 90°–180° and a maximum user weight of 150 kg, the Caliber R3C accommodates a wide range of body types and sitting preferences. The 2D adjustable armrests add further adaptability to the setup.
