‘NAP’ developed by danish designer kasper salto for fritz hansen, is a functional chair focused on well being and comfort. the new chair design not only fits into fritz hansen’s range of furniture icons, but also seeks to meet the demands of modern lifestyle and business. the name of the chair stands for normal, active and passive and is a reflection of salto’s personal attitude. normal means sitting up straight, all the way back into the seat. active is when we are leaning forward to listen or speak, eat or work at a table. passive means leaning back and relaxing.
