Under Desk Keyboard Tray 20in x 11in - Ergonomic Sliding Tray

Our review of the Under Desk Keyboard Tray looks at how this compact 20in x 11in undermount tray performs for people who need to free desk space and improve posture. The tray's single-knob control, 17.75in short track and 360 swivel with 15 degree tilt make it an attractive option for home offices and small workstations where a full keyboard arm would be too large. It is best suited to users with an 18.75in x 24in clearance and at least 27.75in from floor to desk underside, and the review focuses on real-world installation, comfort and build quality.

Key Features

• Compact track: The 17.75in track is short enough to fit smaller desks while still allowing the tray to slide in and out smoothly for daily use.
• Adjustable angle: The tray tilts up to 15 degrees, helping users set a more ergonomic wrist and forearm position to reduce neck and shoulder strain.
• 360 swivel: Full swivel gives flexibility for shared workstations or when switching between mouse sides without moving the whole chair.
• One-knob control: A single control knob simplifies height and tilt adjustments so changes can be made quickly without tools.
• Solid construction: Heavy-duty 1/8in steel arm and MDF tray materials provide a sturdy platform that feels durable during everyday typing.
• Wrist support: The included PU leather wrist rest offers a soft contact point to improve comfort during longer typing sessions.

Who It's For

The Under Desk Keyboard Tray is a practical solution for home office workers, students and anyone with limited desktop space who needs an ergonomic typing position. It is particularly useful for smaller desks thanks to the 17.75in track and compact 20in x 11in tray size.

Users who need a very large keyboard or an extended mouse area, or those with nonstandard desk undersides that do not meet the 18.75in x 24in clearance and 27.75in height requirement, should look at larger or different mounting systems. Likewise, people who rely on textured mousepads or heavy desk-mounted accessories may find the tray surface less suited to those setups.

• Good build quality from heavy-duty steel and MDF gives confidence in daily use.
• One-knob adjustments and swivel/tilt range deliver practical ergonomic control.

Cons
