The idea behind Plana has been to use the curved glass technology to get an elegant and unobtrusive product. The curved glass has been designed to arrange the hinge on the side of the sideboard, so that the main central part – which is the more visible – remains intact and clear. Plana has been developed in two versions, three or four doors; in both of the version, the central doors are made in linear glass while the side doors are made in curved glass.
