A couple of days ago I bought an ultra-cheap standing desk. I don’t think it’s actually meant to be a standing desk, but it goes high enough that a shortarse like me can use it as one. It has a platform for a mouse on one side and a tiltable platform for a laptop / keyboard / tablet on the other. You can use it left or right-handed. Today I used it all day, and have to say I’m impressed with how sore my arms aren’t. My feet are another story — going to have to get some squishy slippers or a little mat to stand on. But yeah, so far, thumbs up.
