The wheelchair package is a foldable seat with backrest that allows to convert the Rollz Motion from rollator into wheelchair. The Rollz Motion is always delivered including the wheelchair package, but this part can also be purchased separate when you have lost it. When ordered as a spare part, the wheelchair package does not include footrests, so make sure to order these too if lost. NOTE: This version of wheelchair package fits the Rollz Motion and the Rollz Motion Rhythm. Contact us if you need a wheelchair package for the Rollz Motion Performance.
