These plans are for a two-level platform that sits on top of an existing desk to bring the height of the main surface to a comfortable standing height. My original desk is 28½” high, and the first platform raises this up 14¼” so the primary surface becomes 42¾” from the ground. This results in my forearms (I’m 6’ 3" tall) resting parallel to the ground when I’m typing at a keyboard. The second platform holds one or more LCD monitors at eye level and sits on top of the first.
The primary surface is ¾” birch plywood, wrapped with a thin strip of wood. This is supported by a frame of 1 x 4” rails and 1½” tapered legs. The rails and legs can be joined with mortise and tenon joints, dowels or pocket screws (I used 5/16” dowel pins, two in each side of the rails). The monitor stand is similar, but with 1 x 2” rails.
My standing desk is finished with several coats of amber and superblonde shellac, then waxed with a good paste wax.

I used a circular saw with a plywood cutting blade to cut the plywood tops and to rip the trim I used to wrap the edges of the plywood. The legs and rails were cut to length using a Millers Falls Langdon miter box, and I used a Henry Peace rip saw to taper the legs. The tapers were cleaned up with a Stanley #6 corregated sole hand plane. Dowels were located with a self-centering dowel jig and drilled with a power drill. I used Titebond III to glue the legs to the rails, and fastened the tops to the rails using small corner brackets.

Last Thursday afternoon, I set up a laptop on the side of my desk, at a height reasonably comfortable for working while standing (see the photo on the right). Over the past couple years I’ve seen several articles on the Internet advocating standind desks as a way to keep a person awake and alert throughout the day. Two weeks ago there was a story in the New York Times Magazine entitled Is Sitting a Lethal Activity?, and the Internets (and NPR on Monday) have been all over the story. The punchline from the Times Magazine story:
Sitting, it would seem, is an independent pathology. Being sedentary for nine hours a day at the office is bad for your health whether you go home and watch television afterward or hit the gym. It is bad whether you are morbidly obese or marathon-runner thin. “Excessive sitting,” Dr. Levine says, “is a lethal activity.”
Last Friday was my first full day at my temporary standing desk. I worked from 6:30 until around 12:30 primarily standing (I’d say around 80 - 90% of the time), and after that I started sitting around half the time because my feet and lower back started to hurt.
Day number two was similar to the first day: after about six hours on my feet, my heels and lower back started hurting. I continued standing until I’d been on my feet for a full eight hours and then spent an hour or so sitting. My neck, shoulders, and right wrist were a little tired at the end of the day, but I think all of this has more to do with using a laptop than standing. The screen is at arm level, so I’m looking down on it all day, and because it’s smaller than my normal monitor, I think there is a bit more hunching to get close. I don’t have my usual trackball either, which probably contributes to the wrist discomfort.
The third day (Tuesday) was rough. I stood the entire day, and migrated off the laptop setup to using my regular computer (v0.2). I also rode my bicycle to work, so my legs were already tired. I made it through the first four hours without any issues, but my back started hurting about then, and by the end of the day the heels of my feet were really killing me. Part of the issue may be that I was in my slippers, and standing on the anti-static mat rather than the carpet because of the new setup. Hopefully shoes with some padding, and possibly an anti-fatigue mat will lessen the pain on my feet.
On day four I wore running shoes and removed the anti-static mat so I was standing directly on the carpet (over concrete). Both of these things helped, but again, between four and six hours into the day, my lower back started to hurt, as did the heels of my feet. But it really didn’t seem as bad as Tuesday, so I may be getting used to it. The new setup with the monitor at an appropriate height, plus a real keyboard and trackball also helps.
Thursday I woke up with a stiff neck and rode my bike to work, so I expected that standing all day would be pretty brutal, but it really is getting easier. The heels of my feet are still a little tired for the last couple hours of work, and my lower back hasn’t quite gotten used to the additional load, but it’s not affecting my concentration like it was in the beginning and I’m starting to be pretty comfortable working at the computer in this position.
Update: It’s now been a couple weeks since I started this experiment. The heels of my feet still hurt a little after a full day of work, and I occasionally experience some lower back pain during the day, but I can feel the benefits already. I’m less tired outside of work, I feel like I’m more productive at work because I am always moving around, and I don’t doubt that the setup will provide long term health benefits over sitting at work and at home for most of my waking hours. The other thing I’ve noticed is that my posture is much better in a standing position and that’s helping to relieve some of the neck stiffness I’d been living with for the past several years. It seems much easier to keep good posture while standing, than having to think about sitting up while in a chair.
All that’s really left to do is make the setup more permanent by building something to set things at the right height and getting an anti-fatigue mat for the floor in front of my keyboard.
