A shell, almost a capsule, that houses and protects without closing itself off. The Martha armchair, designed by Roberto Lazzeroni for Poltrona Frau, achieves the difficult task of combining comfort and lightness. Soft forms and contrasting materials for an airy, relaxed, modern elegance. The design of the Martha armchair is based on the encounter of the two main elements of the frame, both in moulded rigid polyurethane. The seat and armrests form part of a single sinuous open profile, the two extremities projecting outwards. The curved and slightly padded backrest appears to float in the air but is actually fixed to the frame with a hidden system. The entire product is supported by a triangular-section wooden easel structure. The seat’s slight incline towards the back ensures optimal comfort and emphasises the armchair’s dynamic design. The four-legged base is made from solid ash available in the Wengé and Moka finishes. The colour effects and material combinations emphasize the fluidity and lightness of Martha. The outside of the frame is upholstered with a rich shell of Saddle Extra Leather while the inside can be covered in Pelle Frau® leather or fabric. The combination of the two materials is emphasised by the elegant visible-contrast hand-stitching. A soft seat cushion with removable cover in Pelle Frau® leather or fabric completes the product.
