Taking a stand: my experience working at an elevating desk (
"As a professional journalist and software development hobbyist, I generally spend between eight and eighteen hours a day using a computer. This effectively keeps me chained to my desk most of the day, and sometimes late into the night. To combat the physical discomfort of prolonged computer use, I reinvented my home office environment with a focus on ergonomics.
The first thing I did was purchase a better chairthat's easily the most significant thing that you can do to make your office life better. After that, I started to look at desks. Last year, I became intrigued by the idea of a standing deska surface that is high enough to accommodate working from a standing position. Further research into the subject convinced me to buy a height-adjustable desk that can elevate to a standing position. After using it for most of the year, I doubt I'll ever want to go back to sitting all day."
