anyone have a standing desk at work

Love standing - honestly I initially put my computer on an empty paper box, and my keyboard on a stack of manuals. If you do this a lot, consider getting one of those gel-type floor mats to stand on, as hard office floors can make your legs tired pretty quickly. The first few days were wearying, but eventually I was standing all the time.
Since then I have added a tread-desk and a bike-desk. I alternate to prevent overuse injuries.

That sounds interesting. I'd love to have one at work to try out but I know that isn't going to happen. We all share work stations and they all have to be the same. It won't. But I do get up and move whenever I can.

I'd like to hear your feedback on it if/when you get one.

My old job I requested a standing desk for a year, and I finally got it (not adjustable). But it was because my duties really needed a standing desk, I did a lot of work at a filing cabinet, and the standing desk was extremely beneficial, I used to have to pull things from cabinet and have to bend over my old desk to work on it. But with the standing desk, I was able to work comfortably back and forth from the filing cabinet. There is nothing worse than leaning over a desk and looking at work. I also had a lot of movement, I would have to go to copier/printer/other people's area, and the up and down was getting to me.

With the new standing desk, I probably stood/moved a good 60% of the time. And I got a nice high rolling chair, that I was able to use it to sit comfortable at the desk for duties that required me to sit and concentrate on one particular duty.

But since then I got promoted. The girl who has my job, loves "my" standing desk. And I'm back to another sit down desk, but, I would not stand at my current position. I like sitting for what I do now. I make it a point to get up every so often to "run errands". Instead of calling people on the phone, I walk to their desk, etc. I don't think, nor do I want to stand at a desk for the things I do all day now.

In my opinion, if you are constantly up and down for the better part of your day, a standing desk is great. If most of your work is idle, I might think twice.

I have a a varidesk pro and I purchased the imprint standing mat on amazon. I've been using it for several weeks now and I love it. When I have to do something a bit more intense at work, I can easily lower the varidesk to desk level and sit for a bit if need be.

I had an keyboard tray that was adjustable. It went under the desk, could be even with the desk or could come up high enough so I could stand and work. Unfortunately was 3 and 1/2 years ago. I really really miss it. I stand when I work from home, putting the laptop on books and such. I also sit on a fit ball at home too.

I'm contemplating making mine a standing desk. I can sit for long periods of time or be running around doing manual labor. They say standing desks are better for your posture...
