Wheelchair (12603)

I know its specific but I'm hoping someone has a BIG wheel electric or non electric wheelchair that can tilt for an adult size . Unfortunately my daughter has outgrown her wheelchair and waiting for insurance approvals takes forever , i had to borrow one from the loan closet for now but even this one is not adequate she is developing scoliosis curveriture because the chair doesn't have side cushions to keep her in place . If anyone can help me that would be a blessing 🙌
