Workspace Extender for Mouse Arm Support

The VIVO DESK-EXT09 adds a 5.9 by 9.1 inch platform that clamps to desks between .5 and 3.5 inches thick. It is intended for office workers or home users who want a dedicated wrist and elbow rest for their mouse hand. The unit folds 90 degrees against the desk when not needed.

Rigid Platform Holds 33 lbs Continuously

Reinforced K-shaped brackets keep the tray level while supporting up to 33 lbs during sustained use. The foldable design locks flat for storage and swings out to a fixed horizontal position without spring-assisted movement. Plastic and polyurethane construction resists daily pressure from typing or writing tasks.

Clamp Range Decides Desk Compatibility

Adjustable C-clamps accept desktop thicknesses from .5 to 3.5 inches and cannot mount on lipped or beveled edges. Buyers with thicker tops, glass surfaces or profiled edges will need a different mounting solution. All hardware and instructions are included for hand-tightened installation.

Questions about this item

Does the 6 inch tray generate any heat or noise while I work at the desk all day?

No, the tray is a passive polyurethane and plastic platform with no moving parts, so it produces zero heat or noise.

What desk thickness range must I already have for the C-clamp to fit securely?

The adjustable clamp accepts desktops from 0.5 to 3.5 inches thick and requires a flat edge without a lip or bevel.

Will the 90 degree folding mechanism clear my existing monitor arm that clamps to the same rear edge?

The arm folds 90 degrees against the clamp brackets, so it stays close to the desk back and typically clears other rear-mounted accessories.
