After seeing a lot of articles online about how terrible sitting all day is for your body, I decided to try a standing desk. And since most of the articles I read also said that standing all day was no fun, I didn't want to make the transition permanent. I looked for adjustable monitor mounts from Ergotron and Kangaroo, but ones with dual monitors and keyboard trays were $400-600. Plus, reviewers commented that the keyboard trays had a tendency to bounce since they're cantilevered. I knew I could do better for cheaper.
Monitor Parts list:
18"-24" full extension, self-closing drawer slides, depending on your height (2)
1.5" angle brackets (4)
1" black iron pipe
1.5" long 3/8" dia. lag bolts (4)
1 1/4" drywall screws
a gate latch, I found this one at Lowe's. It's nice because the two sections are the same size.
Keyboard Parts List:
pine stair tread
1/5" square table legs (4)
magnetic drawer catches, non-locking (4)
1.5" wide hinges (4)
bronze folding table leg brackets
Estimated cost: $150
NOTE: Stain and varnish all wood before construction. I did it the other way around and it took much longer than necessary, but I was too eager to put the parts together first.
