Skil-Care Bed Bolsters are designed for people who may roll off the side of the bed. Bolsters protect people from falling out of bed without the use of restraints. A person is not substantially impeded from getting out of bed. Designed to fit standard twin and hospital-style beds. Attached straps secure bolsters to bed. Bolsters measure 34" (86cm) long x 7" (18cm) wide x 7-1/2" (19cm) tall and are covered with durable, washable non allergenic vinyl.
