The Silhouette Perfect Chair has been inspired by NASA during the SkyLab program. The recliner places the body in a virtually weightless position. In this physician-recommended posture, the spine, hip, and knee joints are on or close to the balanced midpoint of the muscles. This results in natural relaxation and minimum muscle tension. The Silhouette Perfect Chair gives your neck and back a much-needed breather and allows the body to restore its natural balance. The power recline will bring you into a weightless and relaxing position in under 15 seconds. Available with three choices of wood base color and four choices of premium leather color.
