I've been using an Airtouch by Steelcase for about 4-5 years now. So, years ago, they were redecorating our offices and the woman in charge of it asked a few of us if we could help pick out a desk. Back then we were still in traditional cubes and they were changing the entire office around and starting with the IT department. We went to the main office/showroom of a Steelcase vendor, we were on a tour, after a while everything looked the exact same to me. Anyway, as per usual, I had a lot of coffee that morning and I split off to find a restroom, got lost and I stumbled into the engineering department and I found they were using those Airtouch desks.
When I got back to the group they were all standing around and they said "well what do you think, have you seen anything you like?" I said "yeah, can I show you?" When I took them to the engineering department they had blueprints all over, etc. and the lady guiding the tour said "well but this is actual work office though, this isn't part of the showroom." I said "yeah, I know but I really like this desk, it's exactly what I want."
So me and two other guys in IT had that desk for about a year or so, then finally the entire department got them. Fast forward to this year, the entire company has sit to stand desks, they had a company come in and convert the existing desks to electric adjustable desks. I would say about half the company takes advantage of them.
What I like most about it, is that I can't stand when someone walks up to my desk and hovers over me. I like to look someone in the eye so I always stand up, raise my desk and speak with people that way. I don't know why but it makes me very uncomfortable to sit in my desk while someone stands over me. I do really like the sit to stand thing though, I would say I spend 65% sitting and 35% standing.
