UniMouse + Balance Keyboard + Wrist Rest, Wireless
An Evidence-Backed System for Wrist, Forearm, and Shoulder Pain
The UniMouse, Balance Keyboard, and Wrist Rest combo is a three-piece ergonomic system. Each piece addresses a different cause of pain at the desk. UniMouse holds your hand in a vertical handshake position, reducing forearm pronation during pointing. Balance Keyboard's narrower width keeps the mouse closer to your body's centre line, easing shoulder strain. The matched Wrist Rest supports your palm during typing pauses.
The pieces are designed to work together. The Balance Keyboard Wrist Rest is sized and shaped to pair with the Balance Keyboard at matching height. Per OSHA, CCOHS and ANSI/HFES 100 guidance, height alignment is what makes a wrist rest work. A rest at the wrong height forces the wrist into extension or flexion during keystrokes, raising pressure on the carpal tunnel area.
Why You'll Like It
• UniMouse's vertical handshake grip reduces forearm pronation from approximately 80–90° (flat mouse) to 28–42° depending on angle (Quemelo & Vieira 2013; Aarås et al. 1999).
• Patented hinge sets the mouse angle from 35° to 70°. 5-way thumb support adjusts in/out, up/down, forward/backward, tilt and rotation.
• EMG studies show reduced forearm extensor and upper trapezius muscle load during pointing with vertical mice (Chen & Leung 2007; Ullman et al. 2003).
• Balance Keyboard's narrower-than-standard width reduces the side-reach to the mouse, easing shoulder strain.
• Balance Keyboard Wrist Rest designed to pair with the keyboard at matching height (per OSHA, CCOHS and ANSI/HFES 100 guidance on wrist-rest alignment).
• A 36-month follow-up of 67 VDU workers (Aarås, Ro & Thoresen 1999/2001/2002) showed sustained reduction in reported pain in the wrist, forearm, shoulder and neck.
• UniMouse wireless: up to 6 months battery. Balance Keyboard wireless: up to 12 months on AAA. Compatible with Windows and macOS.

Getting Started
Frequently Asked Questions

Contact Support
Pain at the desk has multiple causes: forearm pronation from holding a flat mouse, shoulder reach to the side, wrist extension during typing, and contact pressure on the carpal tunnel area when a wrist rest sits at the wrong height.
The UniMouse, Balance Keyboard, and Wrist Rest combo addresses all four. Vertical mouse for the pronation. Narrower keyboard for the shoulder reach. Adjustable negative keyboard tilt for the wrist angle. Matched-height wrist rest for the contact pressure. Each piece does its job.

Wireless on both devices. 6-month UniMouse battery, 12-month keyboard battery on AAA.
Designed for Your Comfort
What This System Does Differently
Vertical Handshake Grip
Vertical mouse design holds your hand in a natural handshake position, reducing forearm pronation. Multiple peer-reviewed studies show vertical mice reduce both forearm pronation and forearm-extensor muscle load (Quemelo & Vieira 2013; Chen & Leung 2007).
Adjustable for Your Hand
Patented hinge sets the mouse angle from 35° to 70°. 5-way thumb support adjusts in/out, up/down, forward/backward, tilt and rotation. Right- or left-handed versions, fits any hand size.
Narrower Keyboard, Less Shoulder Reach
Balance Keyboard is narrower than a standard full-size keyboard, with a compact layout that still includes a full numeric keypad and navigation shortcut keys. The narrower width reduces the distance to reach the side-mounted UniMouse, easing shoulder strain.
Matched-Height Wrist Rest
The Balance Keyboard Wrist Rest is designed to pair with the Balance Keyboard at matching height. Per OSHA, CCOHS and ANSI/HFES 100 guidance, height alignment is what makes a wrist rest work and what makes a mismatched one counterproductive.
Long-Term Pain Relief
A 36-month prospective study of 67 VDU workers (Aarås, Ro & Thoresen 1999/2001/2002) showed sustained reduction in reported pain in the wrist, forearm, shoulder and neck after switching to a vertical mouse.
Designed Together, Aligned Together, Adjusted to You
From spreadsheets to design work to email triage, the UniMouse plus Balance Keyboard plus Wrist Rest combo keeps your wrist in a vertical handshake, your shoulders relaxed, and your palms supported between bouts.
Five years of 8-hour workdays and it's still going strong. The angle and thumb support adjust to my large hands — when this one stops, I'll buy another.

FAQs
Got questions? We’ve got answers!
Yes. The Balance Keyboard Wrist Rest is designed to pair with the Balance Keyboard at matching height. Height alignment is critical: per OSHA, CCOHS and ANSI/HFES 100 guidance, a wrist rest that does not match the keyboard front-edge height forces the wrist into extension or flexion during typing, raising pressure on the carpal tunnel area.
Yes. UniMouse's patented hinge lets you set the angle anywhere from 35° to 70°, and the 5-way thumb support adjusts in/out, up/down, forward/backward, tilt and rotation. Right-handed and left-handed versions are available, sized to fit any hand.
Balance Keyboard is intentionally narrower than a standard full-size keyboard, while keeping a full numeric keypad and navigation shortcut keys. The narrower width reduces the distance to reach a side-mounted mouse like UniMouse, which reduces the shoulder strain that comes from sustained side-reach. If you prefer a full-size layout, the new Balance Full-Size combo is also available.
The combo works on Windows and macOS, plug-and-play. UniMouse and Balance Keyboard are both available wired (USB-A on UniMouse, USB-A on Balance) or wireless. The wrist rest is passive and works with any setup.
UniMouse Wireless: up to 6 months per charge. Balance Keyboard Wireless: up to 12 months on 2× AAA replaceable batteries. The wrist rest has no battery.
