Ask HN: Standalone Keyboard Tray/Stand

Hello, all.

I currently have an under desk keyboard tray that isn’t the correct height, and the desk is also not the correct height for my mouse/keyboard. I have been looking around for a keyboard try sized stand that I can adjust the height on. Everything I have found is not the correct dimensions (not wide enough or is essentially a table) or the lowest height is too tall. I found an excellent office chair via past Ask HN threads and was hoping to crowd source a solution to my current ergonomic problem.

Thanks so much!
