OPTIMAL STRUCTURE The structure of the chair was based on some principles for minimum-weight frameworks. The minimum-weight design of a frame structure is such that external loads are balanced by a system of internal axial forces that are withstood by the struts and the ties of the framework. Optimal arrangement of such a framework consists of members that form a system of orthogonal and tangential curves. There are three basic geometric concepts to comply such principles - the involute, envelope and evolute of a curve. All three concepts were used in the chair in some ways to create a minimum weight design for balancing external load of weight of sitting person. As result it can sustain a weight over 100 kg with its own weight less than 7 kg.


PROCESS OF MAKING The frame of chair was made from plywood. This material was chosen because of its pertinent features like strength, respect for environmental and cheapness. 4-mm sheets of plywood were cut on the stripes 6 sm wide. These stripes were joined to the final form and glued layer by layer. Surfaces of the chair were made from cotton ties. Technology of making allows to use materials without any significant leftovers. In combination with structure of the chair based on mimimum-weght design it enables to expend only 2.3 sq m of plywood and 0.3 kg of ties upon the whole chair, which means less than 1/30 of one tree. As a final touch the chair was covered by colored wood wax finish. All materials are eco-friendly, completely biodegradable and were produced from renewable natural resources. Even the glue is environmentally friendly and does not contain any toxic substances.


ERGONOMIC Actual form of surface of the chair was choosen also taking into consideration requirements of comfort by using it. There is no doubt that it is extremely important for a rocking chair. The central part of the back and the middle of the seat were reinforced by additional layers of threads so it gives the best support for a sitting person. The surface of the back of the chair has curved form to retain a waist. The whole form was carefully measured and constructed according human proportions to provide the best functionality. The threads surface by itself also satisfy this purpose because it can change form under the pressure what make the chair extremely comfortable for people with different width of back.


USE IN INTERIOR Despite the prototype was made in white colour, it is possible to change not only colour of the frame, but also colour of threads that makes the chair very versatile and suitable for different types of interiors. Gracefulness and eye-catching form of the chair can make a wonderful contrast with brutality of industrial interior, or support simpicity and adjusted proportions of minimalistic one, or add a touch of modern art to a room decorated in classical style and so on. The chair attracts attention, like a sculpture, it induces to explore it, look at it from every side and look through it. But furthermore, it also has a function and can be used in everyday life with a great comfort.
