Duolift lifting door systems, a combination of the design experience of Defne Koz and Marco Susani and Samet's technology, have been specially designed for double door mechanisms. Duolift and Monolift have been developed through innovative solutions enabling much more comfortable use of furniture. Duolift prevents accidents, such as trapped fingers, with the help of Samet's high technology. For Samet, Defne Koz and Marco Susani developed Monolift and Duolift lift-up door mechanisms, that produces striking and esthetical effects on furniture in two different colors, white and grey. This design was developed to touch the hearts of users.
