Slope

Transparent and lightweight, yet extremely stable and surprisingly cosy! Our SLOPE furniture range is versatile, absolutely weatherproof – and a virtuoso of the play on light and shade into the bargain.


Chair, armchair and lounger are stackable, and the barstool cuts just as good a figure in the kitchen as on the patio. The frame of glass-bead blasted, powder-coated stainless steel supports an easy-care polyester fabric weave. We offer a selection of matching tables.
