A 3D knitted chair design that changes the mood and tone of itself once seated. The extension of threads of different colours create the motion which the effects of two pigment is mixed. Our weight creates this effect of changing shades especially if we move. The gap between threads are created once we sit; which result in the increase of air ventilation. In the market there are no chairs that are designed to interact with the user - in which Grotta is capable of doing so.
