We all know sitting on our butts isn't exactly a boon for our health. But while that knowledge might (just possibly) entice us to swap some of our sofa time for a round of jumping jacks at home, we've got far less flexibility when it comes to work. Enter the Stir Kinetic Desk ($3,890). This smart workspace can be programmed to rise and lower to ideal heights for both sitting and standing, adjusting from one to the other at the push of a button. It even reminds you when it's time to swap positions.
