Taking the impetus and strength of climbing as a reference, the K models of Sancal are a compact and dependable project. It has the clean lines of a basic family, suitable for all kinds of environments in any of its versions. The integrated back cushion strengthens the design and gives a relatively deep seating with a compact overall depth. K is a fully modular product that, when combined with different designs for arms and legs, produces three models, each with their own personality: K1, K2 and K3. The K3 model can incorporate an aluminium or regenerated leather arm-tray.
