With laif®, we have created energy-efficient, sustainable and environmental compatible on a synthetic basis an actively breathing outer surface which enables the ready transmission of air and humidity, and whose performance values far exceed even those of its natural model, aniline leather. laif® is not a mechanically-perforated, hole-punched or pierced surface, but instead a porous-structured material. Upholstery products covered with laif® make it possible to sit in comfort even for long periods – without the unpleasant feeling of “stickiness” which becomes so obvious with conventional synthetics as a result of their sealed outer surface.
