Artek Stool 60
If you've picked up your copy of Phaidon Design Classics and are looking for a good (and affordable) place to start building your design collection, may we suggest Stool 60?
Stool 60 was designed by Finnish architect Alvar Aalto for Artek in 1933. Since then more than a million have been sold, due almost entirely to its timelesss aesthetic design.
It's not the most exciting piece, but it is a nice looking thing to have around the house, which will likely never date and prove a fairly sound investment. You can pick it up now from Skandium for around £97.
