Designer
The unique backrest design is one of the most interesting and fascinating elements of the 4ME product range. Besides the design itself takes inspiration from the branches of a tree, it also provides the ulitmate back support.
The most characteristic feature of 4ME is its unique backrest. The shape of the backrest fastening is not only about interesting design – it is also an important functional element. Thanks to the inner structure, the backrest can follow every move of its user easily. The four-point support ensures even distribution of force when leaning back and the specially designed spherical handles provide additional shock absorption as the backrest moves.
