A (still small) collection of design criteria along with examples that can be considered when designing furnitur and larger structures.

The design process is always a trade-off between different desirable criteria. Otherwise, design woudl be easy–-and boring.

Reconfigurability

• using parts in different configuration/contexts
• the more generic, the more versatile (Lego)

up <-> down
