The SCRW's striking design is brilliant. No matter how tall you are or what table you're sitting at the chair adjusts with just a turn to exactly the right height.
Designed by Manuel Welsky, the chair's seat is a big piece of cork with threads that screw into an aluminium frame. When your tall friend comes over for dinner, just turn the seat till it's at the right height. Those of you who play drums -- or are familiar with drums, anyway -- might recognise similarities to the screw-seat design of a drum throne.
At $US660, the SCRW is pricey, but that's OK because it really shouldn't be the only piece of beautiful adjustable furniture out there. Someday, hopefully, all chairs will be this brilliant. [Welsky via FastCo Design]
