Simple modern straight black retro sofa

This sofa boasts a full, high backrest with a thoughtful ergonomic design to support all parts of the body. The integrated headrest accommodates various sitting and lying positions, making it feel like a second "bed." The frame is made from imported larch wood, which resists deformation and enhances structural stability. The use of spring webbing provides secondary elasticity, adding to the comfort and complexity of the design.
