SUNNY HEART Computer Adjustable Arm Rest for Desk, Ergonomic Wrist Rest Support for Keyboard Armrest Extender Rotating Mouse Pad Holder for Table, Office, Chair, Desk, Black

I bought 2 for both sides. It felt very comfortable and firmly adjusted at the beginning. After several days of using it became a bit shaky and bending. Fingers crossed, that the plastic will not break. I will write another review after couple of months.

Easy to install and works great! My elbow was hanging off my desk when I used my mouse and I was having upper arm pain as a result. This supports my elbow and really helps!

This thing is a piece of s***, the vault that's supposed to lock it in place is plastic like the rest of it and cheap ass plastic and top it off it has no grip on it it looks like a f****** 5-year-old toy interpreter done to this. And when you rush your arm on it you feel like it's going to break. I would not buy this again and I don't recommend it to anyone. Honestly I want my money back.

These really help my shoulders and back.

This product is much cheaper than other ones here on amazon. I'm surprised it worked perfectly. It's decently sturdy. Don't put your whole bodyweight on it and it should be fine...... hopefully. The clamp is padded so it shouldn't scratch anything. The bottom screw isn't padded, but it's plastic so it shouldn't be hard enough to scratch anything. You can cut off a piece of the cardboard from the box it came in as padding.

It's not the highest quality, but it will be good enough if you don't put your whole body weight on it. It made a big difference in reducing my shoulder pain from long hours at my desk. I would repurchase if my current one breaks, which I bought about two years ago, and it's still working well. The only thing is thin foam padding to protect the desk from the plastic has fallen off.
