I recently found out about another low-cost standing desk alternative that converts any normal desk into a standing desk: the Stand Steady Desk.
The Stand Steady Desk comes in two finishes (Black and Maple), is low-priced (currently $140 on Amazon), and very easy to set up (only three pieces plus screws). Sure it’s simple, but it’s also a bit more elegant than just piling phone books on top of your existing work space. 🙂
