Length: 4:11 Mins
Add some ergonomic goodness and/or free up some desk space with this handy keyboard tray.

I'm not a very handy person, but I installed this between 30-40 minutes, which included fetching what tools I do have out of the garage, measuring three times, installation and final setup of keyboard and mouse on the tray.

The product description says this can be installed without "tools". I don't know how they could do that unless they consider a Phillips screwdriver not a tool. Other than my electric screwdriver there wasn't much more I needed for this.

Fits standard keyboard and mouse fine. As you can see my video a gaming keyboard hangs over the side several inches, but that didn't impact me from using those additional keys.

Nice firm wrist pad.

Everything sticks/velcro's down so no shifting around of your keyboard, mouse or wrist pad.

Easy adjustable single knob for tilt and height.

Item seem real metal and hard plastics that will last.

I'm very happy with this item!!

It's a very solid product. Installing it was fairly easy; they include a paper template so you can easily figure out where to drill the holes under the bottom of your desk.

The tray height and tilt (both forward and back tilt) is controlled by one knob; you loosen the knob a little, reposition the tray, and then tighten the knob. Adjusting the tray angle can be a little tricky, but you won't have to do it often once you find an ideal position; from then on you'll just slide the tray in and out (if you slide it at all).

Back-and-forth swiveling action is not adjustable, it's just pretty stiff, so the tray won't swivel unless you definitely intend to swivel it, which I think is good!

The tray includes a gel wrist rest that extends across the entire front, as well as a "3M Precise Mousing Surface" piece of plastic that's about 6x7". Both are optional things you stick onto the tray, adhesive strips are included (though I used carpet tape to attach the wrist rest because it was thinner). I did stick on the mousing surface thing, but I am pretty sure I could have skipped it without missing it.

My only minor complaint is that there is no ridge along the backside of the tray; if you tilt the tray away from you (which is ergonomically recommended), too much tilt could cause your mouse to slide off the back of tray (but on the other hand, if there had been a ridge along the back, the keyboard probably would have had to sit further towards the front of the tray which wouldn't be good either).

The tray is 1/2" thick and made of some kind of very solid composite material. It's about 25.5" wide, and about 11.5" deep in the middle; it tapers so the front is slightly curved and the depth at either end is about 9".

I'm used to other keyboard trays that are adjusted with a handle, so it took me a bit of time to get used to this tray's unique ways of adjusting its position. However, it is a superbly adjustable keyboard tray. It can tilt anywhere between -15 degrees and +10 degrees. Negative tilt is ergonomically best for most people. Even better, the level of the mouse tray is separately adjustable from the keyboard tray, so after you set the keyboard tilt the way you like, you can make the mouse tray level again. Many other keyboard trays will not do this and on such trays, the mouse may roll on its own in synch with the keyboard tilt. I rarely like wrist rests, but they feel great on the 3M, with the tray adjusted ergonomically.

If your desk isn't too short relative to your personal height, you can slide the tray out and then up high enough to turn your sitting desk into a sit-stand workstation. Working while standing at times during the day is very helpful to your long-suffering back. When you're done working, you can reposition the tray to slide all the way under the desk. (Slide your tray out all the way and read the newly revealed label if you're having trouble figuring how to do that; this stumped me for awhile until I found that label.)

The keyboard tray can be adjusted from side-to-side a few inches if it wasn't centered the way you like after installation. It also rotates in an arc side-to-side if you just move it that way.

The keyboard tray has a very solid feel. It's heavy and well-constructed and feels like it will last for years. It's remarkably well engineered.

HOWEVER--this keyboard tray loses one big star from me for one of the lamest Owner's Manuals I have EVER seen from any big corporation. This manual needs a total redo.

Having used many keyboard trays throughout the years, I would rate this one at the top of the list. The 3M gel pads are unsurpassed by any other brand I have used and do make a difference in helping to fight fatigue. Unlike some other trays I have used, this one is very sturdy and resists vibrating, moving when typing or mousing. When you consider the cost of this product compared to others, it should be a clear winner.

I have been experiencing shoulder pain for several months because of poor workstation design, and despite slight adjustments to my positioning, the pain continued. I was also losing some flexibility. I finally spent the money to buy this keyboard tray and I am very glad that I did. My pain has lessened and my flexibility has improved. I'm not back to 100%, but the keyboard tray definitely helped. One tip: Be sure the paper template is 1/2" back from the edge of the desk. You have to drill another pair of holes that are not on the template, and if you drill too close to the edge of your desk, the wood will split.
