Ergotron – WorkFit-LX Sit-Stand Single Monitor and Keyboard Arm, VESA Desk Mount – for Monitors Up to 42 Inches, 7 to 25 lbs – Polished Aluminum

Overall, great product. Monitor arm is strong and sturdy. Very easy to adjust back and forth from sitting to standing position. The 360 degree rotation ability provides for very flexible installation options, and configurations.Only drawbacks are the keyboard tray. Its a little flimsy and flexes with just the weight of your hands on the keyboard. Also, the bumper padding for your wrists is a little high, making it harder to type on lower profile keyboards such as Apple wireless keyboards.

I've been using this for over 6 months now, and love it. I wasn't able to mount it so that I can sit down (monitor power cord not long enough to go up the apparatus and then back down, but I could buy an extension cord; and I had to mount it back far enough on my desk that the keyboard doesn't clear the front of the desk), but that is okay as I don't want to sit anyway. I love that I can adjust everything, depending on whether I am barefoot or in heels, or feel like slouching a little. Everything stays where I put it, and I even have to let my ergonomic keyboard hang off the right edge, and it is still ok. I had been worried that the slide-out mouse tray would break, but it is holding strong, and I have a left-handed, ergonomic (bigger and heavier than some) mouse. Love this product and get no arm pain when I stand at my computer rather than sit. I think my legs have even gotten a little more toned from standing.

why is this so expensive? You can buy the lx monitor arm then buy the keyboard arm on ebay and save ~200$$ .Assembly is simple and the range of movement is great. Way higher than any other solution which is fantastic. it's light and you can hook it onto any desk.I knocked 1 star off because the keyboard tray itself leaves a lot to be desired it's small and everything shakes if you have a keyboard that requires a bit more force to make it click.I knocked another star off because the keyboard tray doesn't have any tilt functionality. as it is, it's slightly inclined forwards so my mouse keeps falling off. I haven't found a good solution but will be looking into it slightly sticky mouse pads?? it's really weird to have to deal with this.

I like that the "arm" for both panel and keyboard are able to be moved around to accommodate where I'm sitting. However, there is still limited areas to mount the unit on the desk. And because I have a hutch on my desk, I find that the work station has more limits to its mobility than I originally expected of it - constantly hitting or bumping into the hutch.Also, the keyboard arm is limited by how far it can move from the mounting pole, which puts a great limitation to where the work-center can be mounted on the desk. When I'm sitting, the keyboard arm often bumps into the desk top. It would almost be better if the keyboard arm had an additional "knuckle/bend" to the arm, to allow greater mobility. The tray does not tilt, which I find a severe limitation.Overall when standing, however, I find this work-station to be of benefit.

This is far overpriced. The LX Desk Mount LCD Arm is $127.99. This stand up is basically two of those items on a slightly longer post, with a plate to hold a keyboard instead of a monitor. This should be $270.00 MAX!! Rip off because stand up desk is a trend. KMA!

This arm system is really sturdy and works well. A couple of issues: The tilt adjustment on the monitor arm is really stiff regardless of what you do to the adjustment screw. I was afraid I'd break the back of my monitor because of the force required to tilt it upright. Also, just because of the geometry of the arms, the keyboard arm partly covers the right bottom corner of the screen when it's set close to the desk (I attached the arm system to the right side of the desk). Overall, it's a great system for a sit-stand setup, in my case a room-scale Vive VR system that I also use for sit-down gaming.

Arrived with all parts present and with picture instructions. It is solidly constructed and requires a sturdy workstation. It took a few hours to put together, since I am not mechanically inclined and took my time! Everything fit well and my monitor is new enough that it did not require an adaptation, for which they provide some hardware if that is needed. Take some time upfront to plan positioning, as it takes up some space and need to make sure it will be in the correct position for your work area when complete. In trialing it out the first day, the units moved smoothly and held in position. Hoping it stands the test of time and will update!

I'm using this with a Dell U3421WE. The monitor weighs 15.57 lb without the stand and so is about 10lbs below the limit for the mount. Even so, it's incredibly unstable. Every single keypress makes the screen shake so much that I can't use it.
