It's really important to move your body throughout the day and I feel great when I can cut down on the hours I spend slumped at my desk. I'm tall, and I generally like being up high; I'm happy as a clam perched on a bar stool. So I already want a tall desk. But one that can move up and down? To pre-set heights? At the touch of a button? SO GOOD.
Mine is the 60”x30” Jarvis from Fully. Keep in mind that you can also purchase the mechanical base and screw on a top surface of your choosing. I have a friend with a huge (and somewhat questionably stable) desktop.
And back when I worked in an office, people generally seemed to like having standing meetings around my desk better than being sort of awkwardly positioned in chairs.
