Abstract
Abstract A seat, which may be chair-like, for patients who must be restrained against leaving the seat, the principal feature being an elongated flexible seat element hung like a hammock but without a swinging function, the buttocks-receiving portion being much lower than the knees-supporting portion so that the patient once seated cannot unassisted pull himself forwardly, while the seat frame prevents escape laterally. There are no straps, bands or other obvious restraining means and virtually no chance of injury to the patient.
