Your desk height was decided by the desk. Your hands should not have to agree with it.

Almost every desk sits at roughly the same height, and almost nobody is that height. So the keyboard ends up a little too high, the shoulders come up a little to meet it, and the wrists bend back over the front edge for eight hours.

A keyboard tray fixes that by moving the keyboard instead of the desk. This one bolts to the underside of your desk and carries the board below the desk top - down to 8.7 in (220 mm) lower - so you set the typing height to your elbows and leave the desk where it is.

It is a steel-framed tray, not a stick-on shelf. The frame is Q235 carbon steel, the board is MDF with a molded wrist rest along the front edge, and the whole assembly weighs 10.25 lb (4.65 kg). It screws on, and that is the part worth reading about before you order.

Down, and tilted away from you

Two adjustments do the real work. The bracket sets the height anywhere from level with the desk down to 8.7 in (220 mm) below it, and the board tilts from +6 deg up to -25 deg down.

That negative tilt is the one people underestimate. Tilting the far edge of the keyboard up - which is what those little flip-out feet under a keyboard do - bends the wrists further back. Tilting it down and away lets the forearms and the backs of the hands run in a straighter line. On this tray the down-tilt is the larger of the two ranges, which is the right way round.

A knob at the bracket sets the angle and locks it. It is a mechanical joint - you set it once and forget it, not something you nudge between emails.

Push it in and the desk is a desk again

The board rides on a linear rail with 9.5 in (241 mm) of travel. Pulled out, the keyboard is in your lap-line. Pushed in, it disappears under the desk top and you get the whole surface back for paperwork, a laptop, or dinner.

The mount also swivels 180 deg, so the board can be angled left or right rather than being locked square to the desk - useful if you sit off-center, or if you want the mouse platform to fall somewhere other than straight ahead.

Read this before you order: it screws on

This is not a clamp and it is not adhesive. The steel frame is screwed into the underside of your desk. You mark the holes, drill pilot holes, and drive the screws with the wrench in the box.

So the desk has to be able to take screws. That means a solid underside in wood, MDF or particleboard, with a flat, clear area of at least 14.2 x 6.1 in (360 x 155 mm) for the mounting frame, and nothing in the way - no drawer, no crossbar, no cable tray where the frame needs to sit.

It will not work on a glass desk, and we would not put it on a thin hollow-core top or a desk you are not willing to drill into. If your desk has a shallow drawer under it, measure the clearance first: the frame and rail need room, and the tray then travels below whatever is up there.

Everything you need to fix it is included except a drill and a bit. Budget half an hour and a second pair of hands for holding the board up while you start the first screw - it weighs over ten pounds.

What actually fits on the board

The platform measures 25 x 9.8 in (635 x 250 mm) - wide enough for a full-size keyboard with a number pad, with the separate mouse platform carrying the mouse alongside it rather than crowding the keyboard.

The front edge is a molded wrist rest, formed into the board rather than a foam pad that slides off, and two small raised strips on the surface stop the keyboard creeping forward when the board is tilted down.

The rated load is 11 lb (5 kg). A keyboard and a mouse are nowhere near that. It is not a shelf for a monitor, a laptop docking station or a stack of books, and it is not somewhere to lean your body weight - it is rated for what you put on it, not for what pushes down on it.

What a keyboard tray does, and what it does not

A tray lets you put the keyboard at your elbow height with your wrists straight instead of bent back. That is a posture and comfort change, and for a lot of people it is the difference between a comfortable afternoon and a stiff one.

It is not a medical device and we are not going to tell you it prevents or treats an injury. If you already have wrist, hand or shoulder pain, that is a conversation with a clinician, not a purchase.
