The tiltable table 45° 'T45' was developed by Kylian K. Keimel during Prof. Wolfgang Wimmer's Ecodesign Class and embodies radical material efficiency. Its geometry offers five distinct height settings that accommodate various postures and body sizes. This makes it both an ergonomic tool and an adaptable spatial element. The table consists of just one material and can be manufactured with nearly zero waste. Originally designed as a studio tabletop for dynamic, posture-friendly work, the T45 transcends its initial purpose, inviting reinterpretation across different contexts.
