strap-o-lounger
n.— «Jail and prison employees call it the “strap-o-lounger.”…They are referring not to the electric chair, but to a restraining device that has led to many serious abuses, including torture and death. Belts and cuffs prevent the prisoner’s legs, arms, and torso from moving.» —“The Devil’s Chair” by Anne-Marie Cusac The Progressive Apr., 2000. (source: Double-Tongued Dictionary)
