Get great posture with a little help from our posture support cushion for chairs. Your lower back will be properly aligned thanks to micro-beads in the center of the posture support cushion. The base of the cushion also helps support your pelvis. Support is provided for your middle back, which is cradled on both sides to encourage optimal alignment. Use the included loops to add your own tie straps to keep the cushion in place. This back support cushion can be used in recliners, cars, dining chairs and even wheelchairs. 13" W x 2 1/2" D x 17" H.
