Extra Large Adjustable Keyboard Tray with Slide-Out Mouse Platform

In this review of the Extra Large Adjustable Keyboard Tray MOUNT-KB07B, the bottom line is simple: this under-desk tray is for people who need to reclaim desktop space while improving typing ergonomics. The tray's roomy surface and separate slide-out mouse platform move the keyboard and mouse beneath the desktop for a cleaner workspace and more comfortable posture. Installation is straightforward for most desks that meet the thickness and clearance requirements, and the tray's tilt and height adjustments make it a practical choice for extended typing sessions.

Key Features

• Save Desk Space: Mounting the tray under the desktop clears valuable surface area by holding the keyboard, mouse, and small accessories below the desk.
• Comfortable Typing Angles: The tray tilts from +6 to -22 and offers 5 in of height adjustment so users can reduce wrist strain with supportive rubber padding.
• Extra Spacious Tray: The 21.3 in to 27 in by 9.5 in surface accommodates most standard and larger keyboards for a flexible fit.
• Slide-Out Mouse Platform: A 5.7 in x 7 in mouse platform slides out to provide a dedicated mouse surface separate from the keyboard area.
• Durable Sliding Track: The assembly slides on a 15.5 in x 5.2 in track that supports forward and backward movement for comfortable reach.
• Simple Assembly: All mounting hardware is included and the tray installs quickly when desk thickness and underside clearance are suitable.

Who It's For

The keyboard tray is aimed at home office workers, students, and anyone using compact desks who wants to free up desktop space and achieve a more ergonomic typing posture. Its generous tray size and separate mouse platform suit larger keyboards and users who prefer a distinct mousing area.

People who should look elsewhere include those with very shallow desk undersides that cannot accommodate the 15.5 in track or desks that cannot safely support the tray's mounted weight. Also consider an integrated sit-stand desk solution if you need dynamic desk-height adjustment rather than an under-mounted tray.

Pros & Cons

Pros

• Sturdy construction and quality materials give the tray a solid, reliable feel.
• Large tray area fits most keyboards and the separate mouse platform improves workflow.
• Tilt range and 5 in height adjustment enable comfortable, customized typing angles.
• Easy to install with the provided mounting hardware for most standard desks.

Cons

• Requires checking underside clearance and desk weight capacity since the track is 15.5 in long and the tray holds up to 11 lbs.
• Clamp maximum thickness of 1.4 in may not fit all thick desktops without alternate mounting options.
