Replace H straps for a firmer, more comfortable trunk support. Yokes have straps for attachment to back wheelchairs, travel chairs and strollers. Quick release buckles on each side of the chest support make a double opening front. A short strap mounts to the side or back of the chair. The lap belt has pivotal mounts so the pull at hips comes at the desired angle.
