If you're into the idea of a standing desk but don't necessarily want to get rid of any desks or tables to make room for one, or if you don't have that kind of budget right now anyway, you might look into getting a standing desk converter like this one, which you simply place on an open surface to grant standing desk functionality to your existing workspace, corner desk, kitchen table, or wherever else you need such a thing.

The u-shaped top surface of the largest desk (42") is large enough to easily hold a pair of 27" iMacs or dual monitors, while the lower surface is where your keyboard and mouse/trackpad or even a 17" laptop can go. The whole thing can adjust from 4.7" to around 19.7"–19.9" tall (depending on which desk size you buy), so you have a good amount of wiggle room to get the perfect height.

Shown here are the specs for the large 42-inch desk converter.

They've got a range of sizes and colors to choose from, running between $99 and $199.
