We've surrounded a core of moldable material with soft foam to create a comfortable chest support that can be formed to follow your body contours. The yoke arms pivot, allowing for tailored adjustments for ultimate comfort. The individual pieces of this support are replaceable, so you can adjust the size or swap worn out pieces for new ones. There are strap attachments on the Yokes for wheelchairs, travel chairs, and strollers. The lap belt has pivot mounts for optimal adjustability. Please see frequently asked questions, #19, for strapping options. If no option is chosen, standard strapping will be sent. Please Note: This product is not a restraint. Please note: Custom colors and/or modifications to any product require up to 7 days for fabrication. Custom and/or modified items are not returnable.
