Works great for the back and neck issues.
Deb
Been using this keyboard/mouse tray about a month--VERY solid, sturdy, and well-designed unit.
David T. Kalinoski
The installation is easy (and obviously I've installed a "FEW").

The build quality of the product is excellent. I bought 2 of these. One for myself and one for my brother. Combined with an adjustable height chair, the ergonomic adjustments that are possible are phenomenal.

Some dimension specs you probably won't find in any literature which might help in the pre-planning stage should you choose to purchase this product.

Length of arm mounting glide track under desk: 22"
Width of arm mounting glide track under desk: 6"
Depth of arm mounting glide track under desk: 5/8"

Width of tray arm: 4"
Depth of tray arm: 8 3/8" Max(in lowest position below desk)
Max height of tray arm: 3 1/2" (in highest position above desk)

Max forward extension of tray arm from end of desk: 5 1/2"

Keyboard surface: 21" wide x 8 1/2" deep. (Keyboards that are deeper than this may fit if they rise over the 4mm back lip.)

*************

That said, you'll want a desk that is no less than 23" deep (from front to back). And since the unit is sort of heavy, you'll want to mount this on a desk whose top is no less than 1" thick and has a closed back. Otherwise the weight of the unit will cause the center of the table to sag a bit.

Other notes:

1. There is some wobble each time you initially rest your hands on the keyboard tray as the tray settles the spring. None while typing. Lift your hand off and the tray rises 2mm-3mm back to where it was before you rested your hands on it.

2. The mouse tray is 1/2" below the keyboard tray top. And like the keyboard tray, there is initial wobble when you rest you hand on it. It settles almost immediately when you use the mouse but in no way affects mouse use.

This keyboard tray is amazingly adjustable. It can be rotated 360 degrees. Although I haven't measured to be exactly sure, it seems to have between a 18 and 24 inch vertical adjustment range, allowing for the keyboard to be anywhere between 9-12" above or below the desktop surface truly allowing it to be used sitting or standing. My desk had a two inch lip and I can still raise the tray 6" above the surface of the desk.

The keyboard tray is deep and wide enough for any standard keyboard and includes a sized-to-fit non-slip pad on which the keyboard can be placed. I can barely, but stably, place a Microsoft Natural Ergonomic Keyboard 4000 keyboard on the tray. The tray also allows the keyboard to be inclined or declined a fair amount.

The mouse tray slides to either the left or the right allowing its use for right or left handed individuals. The mouse tray's area is sufficiently wide for the range of motion required for mouse movement across two monitors.

The overall quality is great and installation is fairly straightforward. The only reason I did not give this tray five stars is that inclination adjustment knob and surrounding enclosure on the underside of the keyboard tray is fairly large and prevents placing the keyboard extremely close to my lap.

I finally have a keyboard tray that I, being as short as I am, can have at the low height that I need, but others can raise it when they want to use my computer. Anyone who tried using my computer before kept banging their knees into my keyboard tray. This new keyboard tray was exactly what In needed.

I also really like how solid it is. We installed a less expensive one for someone else, and it practically bounces with each keystroke, and is difficult to get to stay in any setting other than its lowest position. So I am very happy with how solid this is. Plus it adjusts to any position and stays there when I need it to.

Another nice surprise about this keyboard tray is that it came with a sheet of non-skid rubber matting to place under the keyboard. It is wonderful to keep the keyboard in place. It's too bad they don't include one for the mouse extension.

I have two minor complaints about this keyboard tray. The mouse tray surface is 1/2 inch lower than the keyboard tray surface. I am used to having the mouse at the same level as the keyboard tray, and this seems to make me reach for the mouse more than I had to before. I am thinking of getting some sort of padding to raise the surface of the mouse tray. Or maybe it is just something to get used to.

My other bigger complaint is that there was nothing in the description telling me how big of a flat surface area is needed for mounting the tray. That mounting plate that the tray attaches to is 6 x 22 inches. I was so disappointed and thought I would have to return the tray because my terminal table that I was attaching it to has a support bar that crosses 16 inches from the front of the table.

The quality of this arm is excellent. It's heavy and well made. However, you must have the right desk for this to work. If your desk has a lip on the front edge, this arm will not work (that is unless you possibly add some wood underneath to help it clear the lip, but that also might interfere with your leg clearance). For this to work best, your desk must not have a lip, and the desk top needs to be solid and sturdy as well. This thing costs a lot to send back (it weighs 22 pounds) so make sure your desk is right for this arm.
