Mount-It! Under Desk Keyboard Tray, Adjustable Slide-Out Keyboard & Mouse Platform, 26.5" W × 10" D, Ergonomic Wrist Rest, Height Tilt & Swivel, Heavy-Duty Bolt-On Keyboard Drawer

Perfect for my narrow tall standing desk. My desk is only 18 inches deep, so in lieu of installing it the Track the “normal way”, I installed it horizontally / sideways. This allows me to move the tray Left to Right instead of in and out, which is great for centering the tray within my workspace. The product came in perfect condition, easy to follow instructions, an is very well made - albeit a little bulky at the bottom. The single lever to adjust the unit vertically is super easy. This was definitely a great purchase

I've been looking for a tray for my taller than normal floating desk and I needed something that could go low enough while sitting and tall enough for me while standing. Took me 2 hours to install it but the process was seamless. Things to note of you have a desk made of MDF or substitute wood: - reinforce the plate/rail with a 1/2 inch thick wooden board - spread thin layer of gorilla glue on one side of the wood and press onto the underside of the table (in my case an IKEA countertop) - drill the guide holes into the wooden board - fasten the plate/rail with some stronger wooden screws that are long enough to penetrate both the board and table - finish assembly I have more confidence that the tray won't fall on my thighs and feet now. I'll update this review in the future. Its heavy but looks sturdy and be aware of the length of the rail. You may need to cut the length to accommodate the depths of some tables.

Mine came in not right condition (Amazon gave a discount for the damage) but there are a lot of issues. For the big one, I am not sure if it is only mine or if maybe I was missing a piece but the slide was big enough that rocking it at all in the slide resulted in it falling out of the track. This thing is heavy enough that it dented my floor. If my foot had been over about an inch I would be in the hospital. I was able to mount it so it wont happen again with some extra hardware but I really don't like it. Now for the issues I am sure aren't caused by missing hardware. First is you have to have this thing way back unless you want to be sitting way back from your desk. Other reviewers have noted this as well. This would be way more usable if the tray also rotated as you would really have a lot more adjustabilty. The keyboard tray is okay but every move makes you readjust. I recommend against this one.

This has been a great tool for adjusting my keyboard from sitting to standing, or just from one angle to another. Works be nice if there was an additional swivel to adjust a little more, but I tried multiple ones and this one was the best for me.

I had to remove the center drawer in order to have a solid base to mount the tray, but love it. It allows me to easily move from sitting to standing positions.

Can't say I'd recommend this. It came in pretty shoddy packaging just thrown in a box. The tray itself is bent slightly. The whole thing is crazy big and heavy. The tray wobbles after installing it. It's also hard to slide in and out. Unfortunately it's the only thing I can think of working for my desk setup. If I find something similar in the future I'll be looking for that.

Finally not feeling carpal pain. Working from home w/ the desk level use of keyboard is not good for anyone who spends many hours a day on keyboard. Your wrists should not be bent upwards, but downwards! With the addition of this tray, I can finally sit comfortably w/ my hands in front of me at waist level w/ slight downward tilt so my hands are straight, not bent upwards. This helps w/ anyone who has carpal tunnel syndrome and has fixed the pain I've been getting from working home remotely now that covid has us all quarantined! Even though I have an adjustable desk platform, I don't use it. With this keyboard tray and simple $20 monitor arms, I am easily able to adjust in 10 seconds my position from sitting to standing for both monitors. Plenty less expensive than buying a Varidesk and more ergonomic.

Been waiting to write a review after using it for several months. The only complaint I have is that I need to grease it because it squeaks a little bit from turning, but that is expected and normal. There are moving, functional components, which will always require preventative maintenance from the owner. When extended, you cannot put your full body weight on it without it flexing a little bit, but that is not why we bought it. It is extremely useful for our situation and we’re very pleased with it.
