The RollerMouse Red Plus and Balance Keyboard combo replaces the stretch-and-grab posture forced by a side-mounted mouse with a centrally-positioned rollerbar sitting flush against a width-matched keyboard. Your shoulders stop reaching. The rollerbar stays clear of your typing. Mousing and typing share the same neutral zone, all day.
RollerMouse Red Plus is engineered for heavy desk users who want the highest levels of precision and pain relief. Balance Keyboard is engineered to pair with it, with a height that matches the rollerbar exactly and a width that aligns with your body's centre line.

Matched width keeps your hands aligned with your body's centre. Centred pointing flows directly into centred typing, with no reach, no strain.

What This Pair Does Differently

RollerMouse Red Plus's patent-protected rollerbar removes the need to reach for a side-mounted mouse, while Balance Keyboard's matched width keeps your typing centred. The combination targets shoulder, neck, wrist and forearm pain at the source.

Adjustable sensor resolution, rubber-dotted rollerbar, and adjustable click force deliver high pointer precision. The aluminium chassis keeps the rollerbar stable under pressure.

Balance Keyboard's height matches the rollerbar exactly, and the smallest possible distance between keys and rollerbar means no unwanted mouse activations during typing. Your hands move smoothly from keystroke to cursor.

Memory-foam wrist rest wrapped in vegan leather supports your palms during long sessions. Balance Keyboard's adjustable negative tilt keeps your wrists in a healthy, natural angle.

Balance Keyboard's narrow width reduces shoulder reach without sacrificing the full 10-digit numeric keypad and shortcut keys. Same productivity, smaller footprint.
Long days at the desk demand a setup that works with your body, not against it. The RollerMouse Red Plus and Balance Keyboard combo keeps every input centred, comfortable, and aligned.

Got questions? We’ve got answers!
Yes. Balance Keyboard is engineered at matching height and width, so it sits flush against RollerMouse Red Plus with no gap or step. The matched height eliminates the accidental rollerbar activations that happen when a taller third-party keyboard forces your fingers to drop onto the rollerbar between keystrokes.
Mousing with a centred rollerbar is different from a side-mounted mouse, but most people adjust within 1 to 2 days. The keyboard uses a standard layout, so typing feels familiar from day one.
The combo works on both Windows and Mac. It's plug-and-play on Windows. For Mac, RollerMouse Red Plus drivers are available from the Contour support pages. Note that Balance Keyboard uses a Windows-standard key layout rather than an Apple layout, so Mac users get full functionality with familiar PC key positioning.
Most desk-related upper-body pain comes from reaching to the side for a mouse and from a keyboard that misaligns your wrists. The combo eliminates the side reach by centring the rollerbar in front of you, and supports your wrists with a memory-foam pad and adjustable keyboard tilt. RollerMouse Red Plus is engineered for the highest level of pain relief and prevention across shoulder, neck, wrist and forearm.
Up to 12 months on the wireless model, with 2× AAA replaceable batteries. RollerMouse Red Plus uses a rechargeable battery via USB-C.
