LEM Piston stool by Shin and Tomoko Azumi for Design Within Reach, $750

The classic LEM—shown in a lacquered wood version—is tricked out with all the bells and whistles we like to see in a bar stool. It swivels to make sliding in and out easy. The sleek seat toggles between counter height (26 inches) and bar height (31 inches). Plus, the footrest is on the same vertical plane as the deep seat’s edge—a must for balance.
