A reader wrote in to ask what kind of desks we’re going to be using for the new office.

The ergonomics experts always want you to have your feet flat on the floor. So you have to adjust your seat height first. Then, your arms are supposed to be horizontal while you’re typing. This means you need an adjustable-height keyboard.

Most of the adjustable height keyboard trays are extremely annoying… they’re floppy, flimsy, and limit the keyboard to one location. Therefore we decided to get desks where the entire worksurface can be raised and lowered.

Finally, a lot people praise the benefits of standing up for a part of the day, even if you spend the whole day at a computer, so we wanted desks where the worksurface could rise all the way to “counter height” so you could stand and work. And if you are going to be standing up and sitting down it’s best to have a desk with a pushbutton, electric motor so you don’t get lazy about doing it.
