I started with this design:
- Used only bolts, no screws (other than for the keyboard tray). The Lack table is hollow, so screws are not very secure. Home Depot had bolts of a perfect length. I recommend using washers to avoid crushing the Lack's hollow wood legs.
- I bolted L brackets to the back legs to act as mount points.
- I used mini-vices to mount the brackets to the table. These are cheap at Home Depot. I think they look neat and they also act as additional cable management!
- I padded all feet and brackets so as not to damage the table underneath (so it's a low commitment if you don't like it).
- I also used non-slip material between the padding and the desk, such that the combined effect is a stable, non-slip, quiet structure.
- Later I added the second Lack table for another monitor. I didn't need to secure it, as it doesn't physically interact with anything else.
- Finally, I also added extra legs (not shown) to my Galant desk. The default Galant uses T-legs (seen below), which can rock when significant leverage is applied. You'd be surprised how much leverage you can generate while simply typing. So I bought a couple of additional adjustable legs from Ikea (this links to chrome, I found them in a color that matched the Galant legs in the store). I added them to the front of the desk. I didn't need to screw them in, as when tightened appropriately with some non-slip material between, the pressure holds them in place and keeps the desk from rocking and made everything more stable.
I found that even the best commercial standing desks can suffer from "wobble". With this design, the key is to get monitors with really good stands -- preferably ones that adjust! The dual high-end BenQs shown in the top picture are excellent. I suppose my reasoning is that if I'd rather spend $1000 on monitors than on a desk.
While standing, I wear Crocs (but never outside of my house). I also have a balance board and a foam balance pad. I can easily swap between standing surfaces by kicking them out of the way. Changing surfaces and footwear throughout the day is key to remaining comfortable. I also have a drafting chair, although I never really use it. One of the most surprising things about switching to a standing desk is that I rarely have the desire to sit.
- Cheap, cheap, cheap.
- Totally customized for individual preferences.
- Properly offset monitor and keyboard tray. Many retail standing desks center the keyboard tray relative to the center of the both monitors, which makes no sense. You want one monitor directly in front of you and the other off to the side (right or left). Google images for "standing desk dual monitors" to see some bad examples. Here's an example of what you do NOT want:
- Added bonus is that the 2nd level that the Lack desk creates above the keyboard tray is incredibly useful. I use it to hold my drawing tablet, as well as tea cups, pens, notepads etc.
- Multi-level design. While the lack of adjustability is a con, it creates the opportunity to organize lots of stuff vertically. I have my laptop and a laser printer under the monitors, as well as a USB hub and all my cables etc.
- Not easily adjustable. I have two of those red shelves, so I can adjust 1cm up or down fairly easily. And my monitors have adjustable stands. Otherwise I vary height by standing on different things (which is beneficial anyway). However, if you share this desk or computer with someone else (who isn't a clone of you), then this becomes a major consideration.
- If you're taller than 5' 10", I don't recommend this design. I'm exactly 5' 10", and I think some of the design limitations of the parts used here would make it less ideal for taller people.
- Finding a drafting chair that's tall enough. You need a surprisingly high chair to match the height of the desk. This is where adjustment would be beneficial. Although, shorter people will have a much easier time with this.
- Tweaking. I tweaked mine for a couple weeks after I built it. For example, I added the non-slip material to stop the legs from moving around etc. Minor, but worth noting.
- For the first week or maybe two, you'll be sore and unconvinced that standing is a good thing. For me it was my trapezius and shoulders that needed to adjust to "not slouching" or "persistently shrugging" (check your shoulders right now, are they up around your ears?) :-)
Overall I'd say standing desks are worth it, regardless of which solution you choose. This is a cheap way to try it out before spending thousands on a big heavy piece of furniture. Currently I have no plans to "upgrade", but I'd say any such desk is worth the money. Just watch out for those commercial models with the keyboard tray centered between two monitors. That's a deal breaker IMHO.
