EUREKA ERGONOMIC Height Adjustable Mouse & Keyboard Tray Under Desk, 28x10'' Large Slide Out Swivel Tilt Computer Keyboard Drawer with Mouse Pad for Gaming Home Office Desk, Dual Mount

This tray is fantastic. I would buy it again in a heartbeat. I just don't think that i'll get to that point. I'll go into a bit more detail. Comfort: This tray is very comfortable. It is very easy to adjust. Adjusting this tray is all done via one knob, which is located under the tray. This knob is the only problem that i have with this tray. This knob allows for the entire tray to be adjusted to fit your needs, which is incredibly simple to use. The problem is not with the ease of use, it's with the location. When i slide this tray over my lap and then i slide my body under the tray, this knob resides exactly where my knee wants to be. Disregarding this unfortunate placement, this tray is extremely comfortable, and even offers some limited negative tilt (which i prefer)! At first, i was concerned by the method that the tray slides back and forth, which is just some sliding plastic on metal rails. After using it for a while, it occurred to me that the design was simple on purpose. It is not easy to slide, which keeps the tray in place without requiring a locking mechanism. This allows me to slide the tray in and out without adjusting any knob, but also keeps the tray in place unless i want to move the tray! Sturdiness: This tray is very sturdy. I am the kind of person that leans on the keyboard and slams on the keys (from learning to type on a typewriter), and this tray doesn't even budge when i type on it. It feels like i'm typing on a desk! It allows for multiple movements, which do not affect the sturdiness of the tray. This tray is incredibly sturdy. I speak about how i mounted it in the next paragraph. Easy To Install: This entire tray was not difficult to install. The tray arm assembly can come out of the rail itself, which makes installing the rail underneath very simple. I installed this using the standoffs, as i have a very complicated situation on the underside of my desk. There are actually more orientations under the desk than are advertised, as there are extra holes in the rail! this made it so the very limited space that i had under my desk could be effectively utilized. I would recommend pre-drilling some pilot holes in your desk to ensure that assembly is easier, but other than that this was a breeze.

Nice product! 4 stars because of the cost, build quality is nice and sturdy and easy to assemble and install, took me less than 30 minutes to finish. I like that it is a big area. I use it for gaming and it works well.

I had previously bought a VIVO Large Keyboard tray. The nice thing about it is that it clamps onto the desk/table. That's basically only the nice thing about it. It was very limited in how much space there was for items on the tray. The table I have has a thick edge, so that left very little space for items to be put on the tray. While it fit a keyboard, it wouldn't even fit a regular-sized mouse. I then became interested in this one, and while I didn't want to get one where I had to attach it to the underside of the desk/table, I bit the bullet. I had only measured the width of the keyboard tray to make sure it would fit underneath my table, but my table was slightly oddly shaped as well as having a thick edge. I had not actually taken a look on the underside of the table to see where I would mount the tray, so after starting to mount it, I realized the flat area was just slightly too narrow for the tray. However, fortunately, the L-shaped mount could be facing in instead of facing out... So even with some limitation to the width, I was able to install it successfully. Then, I realized the tray did not pull out as much as I would like due to the thick edge of the table. But again, I found due to the flexibility of installation, the mounts could not be moved closer to the edge, but the tray could be installed to be closer to the edge. So now, I can pull out the tray to the full extent. And then back to the original reason I wanted to replace the VIVO keyboard tray, this tray is adjustable how much room you want to allow for items on the tray, so I set the tray to the lowest position. It may actually be too low now (so I may adjust it to one position higher)... But it's nice to know I have all this flexibility! The photo is showing the limited flat space I have underneath the surface to install the tray. You can see how on the left side, I'm reversing the mount so that the L-shaped mount is facing inside instead of facing outside like on the right side of the tray. Also, you'll see that the left leg of the table is actually blocking where the back mount would be installed, but with this keyboard tray, there's complete flexibility where to install the mounts, so actually on the left side, I installed the two mounts right next to each other instead of one in the front and one in the back. Still extremely stable! Great job in its design!

The main reason I bought this is that it is adjustable. It worked perfectly on my computer table. Be sure to watch many times the video on Amazon on how to assemble it, along with the minimalist paper instructions. Both help. It is straightforward. We assembled the slide out shelf and then had someone under the computer table hold it in different positions, while someone sat at the table to check the positions suitability. Then we switched. The the person under the table marked where the screws would go in holes in the brackets to attach to the underside of the table. Then we flipped the table over, aligned the brackets to the marks on one side. Drilled only a 1/16 inch deep pilot hole with a 1/16 drill bit. Just a very small hole worked well to get the screw started. Then we did the same on the opposite side, but we used the holes in the brackets not our marks to guide where we put the screws. The product comes with extra screws and the two hand tools you need-allan wrench and small Phillips head screw driver. Took about 2- 2.5 hours, but could take less, if you do not need to test and adjust the position under the table. Seems sturdy and well made. The walnut color matched out desk. Excellent product.

Be aware the keyboard tray is actually 28 1/4" wide. Made a difference to me for a built in desk with chair opening. edited after returning the first purchase and buying it again: First, this is a pretty good tray. Easy to install and pretty sturdy. Some commented that the tightening clamp interfered with your knees. Doesn't seem to be a problem for me. I'd be happy with it, but it's just not as good of an idea with a stand up desk as I thought. I gave up on the built-in desk I tried on my first purchase and bought a stand-up desk. If you want to slide the keyboard under the desk, you have to lower the tray to get it to fit under the bracket with the keyboard. That puts the keyboard about four inches below the desk. I'm tall, so I need the desk all the way up when I stand, and then the keyboard is too low. The other problem is that when I stand, I want to rest my wrists and elbows on the table, but the tray keeps me too far away to lean on the table as comfortably as I was without the tray. So when standing, a keyboard tray isn't that great. I may decide to push in the tray, clear my desk and put the keyboard on the desk while standing. If you're tall and don't mind not being able to rest your arms as well on the desk, you will have to loosen the clamp and raise the keyboard to desk level. Then you'll have to be loosening the clamp and repositioning the tray every time if you want to stow or unstow the tray. This is a comment that probably relates to all keyboard trays with a stand up desk. It's only about 50% as good of an idea as I thought. Great for sitting down, not so great for standing up. My last comment is that the tray isn't quite wide enough for my keyboard. It fits, but the tray would be better with another inch of width.

It took me a bit over an hour to install, and it was worth the effort and expense. It's certainly not inexpensive, but the materials are high quality, the directions clear and thorough, and the results are all I had hoped for. I was concerned about mounting this because my desk has a 1" metal bar supporting the top along the front edge, but the design includes very flexible installation, both in where to position the support arms as well as 3 levels of height adjustment for the tray itself. I also like that the tray is wide enough that I don't feel boxed in, and once it's installed, it looks like it came with the desk, not like an add-on. The in/out action of the tray is super smooth thanks to ball bearings on both sides, and it gently clicks into place when fully under the desk, so it won't accidentally slide out when not needed. The only issue I had during installation was that several of the screws used to attach the unit to the desk almost came through the desk top, which is 1/2". They didn't actually break the surface, but if I look hard I can see very tiny dimples where they are located, so just be aware of that. But otherwise, I'm super happy with the results and would highly recommend this if, like me, you're wanting to free up some desk space and want something that doesn't just clamp on.

Works well for electronic standing desks - it fits over the bars nicely and provides more cable routing support under the desk if needed. A little wobbly left to right but not a huge deal. Its the spacing of the slide device not the tray itself etc. Everything feels solid and is pretty well machined. My biggest gripe with all of these types of under desk keyboard trays is that they never come out far enough. For tall people who like to put their legs up and not have their face right in the screen, they need to come further out. The palm rest for me was extremely hard and caused a lot of pain. I was so thankful it wasn't glued on and could be unscrewed from the bottom. Plus it provided a bad angle for my keyboard, mouse, and chair. Now that leaves three holes in the tray but whateves. It would have also been nice to have had a full tray mouse pad incase you wanted to take the wrist pad off. I've bought a couple full size that I'm going to cut down to size and use double sided tape probably. I am actually considering making a new keyboard tray that is longer since that's probably the easiest modification to get some extension from it. A manufacturer fix could be: they could make the slide metal longer and have a couple stop locks that can be repositioned to allow the tray to slide out longer for people of different heights that need to be a bit further away. Another thing for standing and typing that might be good is an attachable tray wall on the top for negative incline typing. Overall, I am fairly impressed with this keyboard tray and the flexibility of it. I hope they address my concerns for the next version or separate version released. Lastly the adjustment knob underneath, its not the greatest and does hit the knees sometimes and you need to reposition, but not terrible compared to others I've used. I've only seen one other super expensive brand that had a longer metal arm and small adjustment knob on top, but that one itself had tons of flaws. Something like that probably wouldnt work with this design. Another thing to look into if you need more flexibility and ergonomics like me, is using a wireless keyboard and mouse and trays that attach to your chair instead of the desk.

Long review. Short summary: 1. No fatigue or pain after 8/10 hours at the desk. 2. Plenty of space for keyboard and mouse. 3. Adjusts exactly where I need it. 4. Easy to install. 5. More cost-effective than buying a $1000 chair to adjust to your desk. 6. Very happy and would recommend. 7. tray adjustment isn’t as smooth as the very expensive ergonomic trays, but the difference in smooth movement isn’t worth $500. I installed this on my adjustable height desk, 2x4 ft top. I was able to install it over the crossmember on the adjustable height desk without any problem. To minimize fatigue and pain, ergonomic experts suggest that you’re legs should be bent at the knee at 90°. Your upper arms should be bent 90° at the elbow, with your forearms resting on the armrests of the chair, allowing your hands to move free, and your head pointed straight forward. I’m able to obtain the correct settings for my arms and legs with this tray and my $100 big box store chair. I’ve had very expensive ergonomic trays at past companies where I have worked and I wasn’t sure if this cheap one would adjust enough for me, but works just fine. I just leave it in the position where I use it as I have no reason to put it under the table on a regular basis. I use the LARGE Microsoft ergonomic keyboard and the tray has plenty of room for the keyboard and mouse. I posted one picture with my big ergonomic keyboard on the tray and another with a regular size keyboard. A little vegetable oil might help it slide more smoothly when you try and push it all the way underneath the desk, but I didn’t want to try that as I worried it would allow the tray to move while I’m typing. Amazon has some very inexpensive adjustable height desks starting around $130, I would HIGHLY recommend getting one to go with this . A 2’ x 4’ top is plenty of space when you have this tray. It makes it even easier to get comfortable relative to the position of your chair. The only thing I might change would have been to install the tray a little off-center to account for how my 24 inch monitors fit on my desk.
