These trapeze bars are designed to help patients independently sit up and reposition themselves in bed. They have a free standing base that allows for easily adjustments to better meet the patients needs. They can be tucked under the patients bed to take up very little space or be placed next to a bed to allow wheelchairs to easily fit between the base's legs. The frames are made out of durable angular carbon steel with a polyester coated finish. Their high stress areas have been reinforced in order to reach a weight capacity of 500 pounds for the P260 and 700 pounds for the P270; some easy tool free assembly required.
