For simplicity, assumptions about chair coordinate system were made. Next was market analysis on the basis of three existing products, all belonging to higher price end. They were compared on the basis of fullfiling the required functions and are accordingly used as basis for later analysis. With help of existing solutions and morpholigic matrix two concepts were made with described work principles. The concepts were graded and better was chosen so calculations can begin. The calculations were done from bottom to top. Crucial part was to determine inputs, that is, loads. In the end finished product is shown with desrcibed working principles.
