Overview

The Cooler Master Caliber X1C (CMI-GCX1C-GY) is an ergonomic gaming chair built around a standout feature: Cool-inTech fabric technology. Unlike standard mesh or PU leather gaming chairs that trap heat during extended use, the Cool-inTech fabric actively manages airflow by drawing hot air away from the body and circulating cooler, drier air across the seating surface. The result is a measurable 1-2°C temperature reduction compared to conventional gaming chairs, addressing one of the most common complaints among users who spend hours seated. The fabric itself has been rigorously tested for durability, passing thousands of runs of abrasion and pilling resistance testing, and is made from formaldehyde-free materials.

Beyond its cooling capabilities, the Caliber X1C is built for all-day comfort and adjustability. The chair reclines a full 180°, letting you lean back completely for breaks or naps. The 4D armrests adjust in four directions to accommodate different desk heights and arm positions, while the included lumbar support cushion helps maintain proper posture through long gaming or work sessions. The aluminum base provides a stable foundation with smooth 360° swivel, and the overall construction reflects Cooler Master's focus on durability. At 54.5 pounds with dimensions of 21.3 x 27.6 x 54.3 inches, this is a substantial chair designed for users who prioritize sustained comfort and temperature management.

Key Features

SUPERIOR COOL-IN TECHNOLOGY - Cool-In fabric technology utilizes jade powder particles and unique star-shaped yarn to improves heat dissipation and breathability,providing a temperature 1-2° lower than ordinary gaming chairs. In addition, Cool-In fabric technology is scratch-proof, dust-proof, and easy to clean.

LARGE & FLEXIBLE - The Caliber X1 Series is 10% larger than the Caliber R1 and comes with additional features to provide maximum comfort for all body types. You can always find your most comfortable position by adjusting the seat height as well as the 4D aluminum armrests.

Zero-Gravity Experience: The class 4 gas lift, 330-pound maximum weight capacity, solid steel frame, and aluminum alloy 5-star base were all designed for a weightless experience no matter sitting or lying down. In addition, the exclusive tilt tension mechanism allows you to rock back and forth instantly.

Comfy and Ergonomic: The X1 series has been designed with a thick padded back, cold-molded foam seat, high-density neck rest, and lumbar support to help you reduce neck strain and spine pain during long hours of sitting. In addition, it can roll smoothly with the 360° swivel and 75mm multi-direction PU casters and can be reclined 180° as needed.
