The Sprung Lounge Chair is designed to meet the needs of my client, Ariel Coello. Posture, knee relief, comfort and support are the four most important components of the chair.  The challenge was to take a rigid, angular and sharp material, plywood, and transform it into a soft, comfortable and relaxing piece of furniture. This was achieved with ergonomic flowing lines contoured to the shape of Mr. Coello’s body and the installation of a spring system at each “slat” spaning the length of the chair which allows for manueverabilty and bounce as extended periods of sitting will be expected.
