I use Varidesk. Its a ~35 pound adjustable platform you place on top of a normal desk. There are handles on the side so you can easily change the height to a few settings.<p>Specifically, I got the Varidesk Pro Plus 36:

Would monitor/keyboard/mice cables get crushed if you keep the desk down? Can it support two 24"+ monitors?<p>It's incredibly durable (it'd won't tip over short of putting your entire weight on it in the elevated position). Use it for 2-3 hours/day (with a compression mat I got from costco for $20).<p>There are a couple models, and none are that cheap ($300-$400), but I've had back pain and poor posture all my life so I figured I'd invest what is typically 1 month of my living expenses into this.
We give everyone, one of these desks....<p><a href="http://www.ikea.com/ca/en/catalog/products/S49022524/#/S59022528" rel="nofollow">http://www.ikea.com/ca/en/catalog/products/S49022524/#/S5902...</a><p>We had existing desk tops so we just had someone come in and install the legs. They work well and given that we tend to average 4 27" monitors per person they handle the extra weight well. Mechanical riser's are awesome!<p>They also rise fairly high, important when you have someone who is 6'9" on your team:)<p>Just don't forget to buy a standing mat to, ummm, stand on.<p><a href="http://thewirecutter.com/reviews/best-standing-desk-mat/" rel="nofollow">http://thewirecutter.com/reviews/best-standing-desk-mat/</a><p><i></i>EDIT<i></i> Yes, the mat really matters, we've had a few ergonomic experts in and their advice usually varies but they all agree on using a standing mat.
At our office we have Haworth Planes Height Adjustable [1], which I like and many others that visit inquire about them. They are premium but they will last, cost is ~$1,200 [2]<p>Pro-tip, get the wheels; everything should be on wheels, makes all the difference.<p>[1] <a href="http://www.haworth.com/home/resources/design-tools/image-search?searchQuery=Planes%20Height%20Adjustable" rel="nofollow">http://www.haworth.com/home/resources/design-tools/image-sea...</a>

I have an Evodesk, which is the cheaper version of the NextDesk. I picked it because I was able to get a curved work surface without a significant added cost, along with a memory controller (save your height settings and 1 click adjustment from sit-to-stand), and a cable tray.<p>It's sturdy enough for my laptop and 2 monitors from my sit height (~25ish? inches) to my stand height (~46? inches). The cable tray was a bit difficult to fit a surge protector into but I eventually found one that worked. The top is a bit different from normal desks, but it feels fine to rest against and use my laser mouse sans mousepad.<p>Most of my coworkers have some variant of the Geek Desk.
I got this desk earlier this year:<p><a href="http://amzn.com/B00JREVI5G" rel="nofollow">http://amzn.com/B00JREVI5G</a><p>after having tried simply raising a "regular" desk to standing a year or two ago. Standing all day didn't work for me, but the crank-up makes it so I can stand in the morning and then sit for the afternoon. FWIW I use it cranked nearly all the way up and I'm 6'0" -- it might not be tall enough for someone taller than that. The crank is easy to operate and fairly smooth.<p>It's got a large surface for keyboard, notebook, coffee, etc. The second tier comfortably fits two external monitors + laptop.
I use an Ergotron Workfit-S: <a href="http://www.ergotron.com/ProductsDetails/tabid/65/PRDID/378/Default.aspx" rel="nofollow">http://www.ergotron.com/ProductsDetails/tabid/65/PRDID/378/D...</a><p>It's very quick to move up and down, and the keyboard tray and monitor are independent. Not much adjustibility on the monitors, but otherwise I have no complaints.
I built the standing desk on Mint's design blog: <a href="http://www.mintdesignblog.com/2012/08/diy-standing-desk/" rel="nofollow">http://www.mintdesignblog.com/2012/08/diy-standing-desk/</a><p>Cost me about $60. I polyurethaned a plywood top instead of buying an Ikea top. Plus I stacked some books as monitor stands.
Built my own. 4x4s, 2x6s, and plywood. Measured to exactly my height. It's about $80 of wood and ~40 minutes to assemble.<p>The only problem is it's too big to fit through doors so it has to be disassembled to move.
