Chill Out chair for Chace

Chace is 6yrs old and has cerebral palsy. He us unable to walk or sit independently. We would like to be able to purchase for him a Chill Out chair. This chair will give him someplace other than his wheelchair to sit. The Chill Out chair provides support and propper positioning for children, such as Chace, that are unable to sit up by themselves. Thank you in advance for your support and kindness.
