The first step toward realizing this dream was taken with a concept presentation to Ersa by a design team consisting of Ece Selamoğlu Yalım, Oğuz Yalım and Feride Toprak. Sketches, which began with two symmetrical and separate pieces, resulted in the first model of the product. After calculating the correct angles and dimensions which would make the chair more comfortable and ergonomic, the product with a mass image was given light metal footing which streamlined the angular lines of the seats. The final step for the development of the product prototype was the selection of proper materials. In this stage, materials were integrated with the design and the basis of it all was comfort. Dust-proof, non-allergenic, wipeable felt cloth offered colour options for those who wanted to emphasize the fun aspect of the product and minimal chromium or dyed metal footing supporting the light-look were used. After ergonomic revisions were made to the prototype, serial production was initiated. During the 4-month product development process the opinions and preferences of not only the ''guests'' but also of interior architects were taken into consideration. Twins' character was targeted not to compete with the style of architecture to which it belongs but to contribute to visual integration and provide motion.
