Markus Johansson named the Coquille Sofa after the French word for "shell", which is often associated with a scallop shape.
"I toyed with inspiration found among mussels and shells, and I've been working with different levels of softness and hardness to render Coquille as comfortable as possible," he explained.
The designer attached curved pieces of polyether foam to the wooden frame to make the ribs around the base and back.
Layers of soft padding were added on top, creating gently rippled contours like the exterior of a shell.
The sofa is upholstered in a light grey fabric and patterned by the shadows that fall across the surface of the undulating form.
It will be displayed at Salone Satellite, part of the Salone Internazionale del Mobile taking place next week from 8 to 13 April.
