Features
Legendary Micro-Woven Cloth Surface
The QcK Heavy uses SteelSeries' micro-woven cloth technology to provide consistent mouse tracking across a wide range of sensitivity settings. The high-quality cloth surface is designed for smooth movement and reliable sensor accuracy during both competitive and casual gaming.
Extra-Large 900 x 400mm Layout
The XXL format provides an expansive desktop surface with space for both keyboard and mouse. Its generous dimensions are especially useful for low-sensitivity gaming setups that require large sweeping mouse movements.

Thick 4mm Construction
The 4mm-thick QcK Heavy design provides more cushioning and stability than thinner mouse pads, helping create a comfortable surface for long gaming or productivity sessions while also reducing the effect of minor desktop imperfections.
Stable Non-Slip Rubber Base
A durable rubber base grips the desktop and helps prevent unwanted mouse pad movement during fast swipes and intense gaming sessions, providing a stable foundation for consistent control.
Optimised Sensor Tracking
The micro-woven surface is engineered for accurate tracking across both low- and high-DPI settings and works with modern optical and laser gaming mouse sensors.
Durable and Washable
The QcK Heavy is designed for long-term use and can be cleaned when required, helping maintain a consistent gaming surface over time.
- The XXL format is suitable for combined keyboard and mouse placement.
- The mouse pad does not include RGB lighting or electronic components.
- Surface feel may vary depending on the mouse skates and sensitivity settings used.
- Allow the mouse pad to dry fully after cleaning before use.
