FLEXX is a modular furniture construction system which is built from standard parts.
Numerous combinations can be made from columns which are 420, 820, 1220, 1620 and 2020mm high.
The overall depth of the unit is 400mm.
The overall length is multiples of 400mm plus 20mm.
For example, a unit which is 3 columns wide would be 3 x 400 = 1200 + 20 = 1220mm long.
