StarTech.com Full-Motion Under-Desk Keyboard and Mouse Tray
340 mm height rangeTilt and swivelWrist restMouse pad
Most keyboard trays give you one height and one angle. This one is full motion: a spring-assisted paddle lets you set the height anywhere across a 340 mm range and lock it there, the platform tilts +15 to -13 degrees, and it swivels 180 degrees either way when the tray is below the desk — so it fits the person rather than the person fitting it. The platform is 670 x 255 mm, sized for a full-size keyboard and a mouse together, with a built-in low-profile wrist rest in soft-touch leatherette along the front and a mouse pad with an anti-slip underside that mounts on either the left or the right. There are ledges at the back of the shelf so nothing slides off when the tray is tilted, and it pulls out to 470 mm from the desk edge. Capacity is 2 kg. In the box: a mounting template, an adhesive foam pad to protect the desk underside during adjustment, and four self-adhesive cable clips.
Compatibility — check before buying:
This is a fitted tray, so measure before you order. StarTech states you need 750 x 147 mm of surface underneath the desk for the mechanism and a desktop of 20 mm thickness to mount into — check for a drawer, a frame rail or a cable tray in that footprint first, and note that a glass or thin floating top will not take the fixings. If you cannot drill, the clamp-on StarTech tray is the alternative and we stock it. Two limits worth knowing. The 2 kg capacity is sized for a keyboard and a mouse, not for leaning on: it is a tray, not a shelf. And the 180-degree swivel only applies when the tray is below the desk — swung up above desk level the movement is restricted, which is why the adhesive foam pad is supplied to protect the underside. On the gaps: StarTech does not publish the product weight or the platform material for this model, so we quote none. StarTech backs it for 2 years with free lifetime 24/5 multi-lingual technical support.
Best For
✓ Desks that are too high to type on comfortably
✓ Shared desks where two people need different heights
✓ Sit-stand setups that need a second adjustment range
✓ Anyone who needs the desktop surface back
✓ Left-handed users, since the mouse pad swaps sides
✓ Full-size keyboards plus a mouse on one platform
Key Features
Height set anywhere in 340 mm
A spring-assisted paddle rather than three fixed notches, so the tray goes exactly where your forearms want it and locks there.
Tilt and swivel too
+15 to -13 degrees of tilt and 180 degrees of swivel either way below the desk — the angle matters as much as the height for the wrists.
Wrist rest and mouse pad built in
A low-profile soft-touch leatherette rest along the front and an anti-slip mouse pad that mounts left or right, so nothing is bought separately.
Nothing slides off
Ledges at the back of the shelf hold the keyboard and mouse in place when the platform is tilted, and four cable clips keep leads clear of the full range of motion.

Frequently Asked Questions
Will it fit my desk?
You need 750 x 147 mm of clear space under the desktop and a 20 mm thick top to mount into. Check for drawers, frame rails and cable trays in that footprint, and note that glass or thin floating tops will not take the fixings.
Can I mount it without drilling?
Not this one — it uses a mounting template and fixes into the desk underside. If drilling is out, StarTech makes a clamp-on tray and we stock it.
Does the mouse pad go on the left?
Yes. The mouse pad mounts on either side of the platform, so left-handed users get the same setup without compromise.
Singular Expert Insight
The height paddle is what separates this from a fixed tray: a shared desk can be reset in a second instead of being a compromise for both people. Just check the 750 x 147 mm footprint underneath before you commit. See our
keyboard accessories and our
mouse pads and wrist rests.
Buyer’s Guide
Buy it if
Your desk is the wrong height, you can fix a tray to its underside, and you want height, tilt and swivel rather than one fixed position.
Skip it if
You cannot drill into the desk, there is no clear space underneath, or you need more than 2 kg of capacity.
Also consider
The clamp-on StarTech keyboard tray if drilling is out, or a wrist rest if the height is already right.
