Ergonomic R-Go Arm Rest for Desk - Adjustable Wrist & Elbow Support with Soft Sponge Padding - Pain Relief Keyboard Tray for Office & Home Workspace - Easy Clamp-On Design (Black) | Perfect for Typing, Gaming & Computer Work

I've been using this on a relatively thin sit-stand desk from Ikea. For a couple of reasons, I've ended up taking this off for now.Installation is easy, with a couple of clamps at either end securing the wrist rest to the desk. However, if you place any weight on the rest, it does have a tendency to lean down. I don't feel like it'll come off, but it certainly doesn't have a sturdy feel to it.The padding is good the support it provides is definitely better than not having anything at all. It's a good replacement for the padded type of wrist rest that sits next to your keyboard.One big issue for me is that, as I shuffle around in my chair throughout the day, my knees are at risk of bashing into one of the two clamps underneath which secure it to the desk. I do rearrange myself quite often throughout a workday, and would painfully bash one of my knees on a clamp at least 3-4 times a day. After having enough of that, I ended up removing the wrist rest from my desk and went back to a traditional desktop rest instead.Bottom line: sturdiness will depend on your desk's thickness probably, and get some padding for the clamps to save your knees. You may find more value spending less for a desktop wrist rest if you have the space for one.
