A chair having a pair of restraints against a sitting user's knees. Each restraint is a J shaped bar having an end that curves around in front of the chair, such that the user may sit with each knee in the space between the curved end of the restraint and the front of the chair and the back supported against the back of the chair. The device thereby maintains the lower end of the spine in an erect position. The restraints are adjustable to accommodate various sizes of the users. The restraints are spring loaded for additional comfort to the user. In another embodiment, the seat includes a seat hingeably supported on a base such that, in one version, the seat moves forward to provide additional support when the user sits down. In another version, the restraints are pulled back against the knees when the user sits down.
