Review: This is a good keyboard/mouse tray. - Overall I am satisfied with this keyboard/mouse pad tray. I do question the need for assembling the tray part that your keyboard sits on. This was the most time consuming part of assembly and I think it could have been built in one piece. Other reviews emphasize the need to check for and measure under the desk for any obstructions that might prevent attaching the tray to the desk and for tray moving distance. Also measure the thickness of the edge of the desk that the clamps go on to. I think, but am not sure, that the maximum thickness is 1.75" s. Both of these suggestions are good ideas. You will end up with a few extra screws when you are done. NOTE: Look for the L and R marked on clamps and track rails. Also, during assembly, you can choose between two options for how far the tray extends from under the desk. Once the tray is assembled attaching it to my desk was easy. Soft plastic pads prevent the clamps from marring the desk top. It is sturdy BUT you should not lean on it. It seems to be good value for the price and should fit just about any desk. My mouse pad has all the space beside the keyboard that it needs. I feel that it looks good, seems to be of good quality, and works as advertised.
Review: Very Sturdy; Probably Too Low to Fit Over Legs But Makes a Great Shelf/Drawer - I needed a clamp on drawer, but unfortunately my IKEA desk has a metal support bar lengthwise underneath that means only 6" for the drawer to slide back. I couldn't find any long skinny drawers (I need something that can hold rulers) or ones with a lot of clearance but saw this. It's fantastic! I think it would suck as a keyboard tray for my setup because it would jam against my knees or thighs (I sit high enough to use a keyboard on the actual desk). However, putting it off to the right as a rimless drawer keeps it nicely tucked away. And it is *solid*. Heavy metal and wood parts, very well machined. It slides fairly well though one glide is a little stickier than the other. It has enough clearance even with the back plate to slide back under the support bar. It holds very firmly to the 3/4" desk edge. While it's not a complete match to my pale maple veneer desk, it's tonally close enough. Now I have room for my cat's fleece pad in front of my right monitor and can still get at my organizer box of office supplies. Plus my new left monitor has a remote that sits on the sliding shelf where I won't lose it. I even put it together myself despite not being very strong or tool savvy. The instructions were nice and clear with a good mix of illustration and text, and a phillips head screwdriver is easy enough to use. I did position it over my computer so now it's slightly awkward to press the power on switch, but even though I have a huge tower there's still plenty of room especially as I generally only need to press that button once a day. Things that would make it even better: Black clamps and hardware to blend in more with my chair, keyboard, mouse pad and monitor base. Being one big shelf (it comes in two halves that bolt together with a backplate, which maybe gives it more center support, who knows, but that means the two halves don't match in grain or exact hue). Having some sort of grip underneath center front to help pull the shelf out -- needn't be big enough to jam into legs for someone using it for a keyboard, could even be a smoothly polished groove -- my hands are steadily seizing up and losing grip so even a smooth little ridge or bump on the bolted on back plate's edge near the tray front would go a long way. Having a tiny bevel at the bottom front; it currently has a sharpish edge that presses into my fingers when pulling the shelf out from under the desk. All of these are minor quibbles, none of them worth docking a star.

### ⭐⭐⭐⭐ Minor fixes made this perfect for my use.
*by I***K on November 24, 2025*

This is a nice keyboard tray. There is a known issue of the tray walking away from you as you type. My fix was to purchase a Barrel Bolt Latch and mount it on each side to keep the tray from doing that. The extended pin prevents it from walking. Had this come with something like that, they'd have gotten five stars. The width accommodates my keyboard and my rollerball mouse, along with a wrist rest for each. My desk is a lesser cost up/down desk so I needed to take into consideration the measurement of the space allotment under the desk so it didn't interfere with the up/down drive pin. This works and I can move the keyboard at a whim, not locking me into a specific position at the desk. Value for the money I think is very fair. Drill accuracy was good, very easy to assemble. The ease of use is great. Put a lock mechanism into play on this and you have a great tray. I am very well pleased with this set-up. I don't need the tray to tip forward as the pad I have it on does this. I adjust the height of the desk for ccommodating my wrist/hand tilt. Ergonomic perfection? Nop[e. But it works for me.
