Your desk might soon be getting a lift: Ergonomically minded office-furniture designers are giving your seat the boot — at least for part of the day — with desks that are meant for both standing and sitting behind. California-based GeekDesk makes an electronically adjustable desk that can go from seat height to standing height with the push of a button. The desk enables you to give your back a break and give your body some variety, and proponents swear the ability to switch from seated to standing during the day makes them more productive. $800, geekdesk.com
