I have a question and wasn't sure where to post. I'm hoping someone may know or can point me in the right direction. I have a 27 year old sister who has cerebral palsy and is wheel chair bound. My mom had to make a harness to hold her into the car seat, she drives an 04 accord. I was curious if anyone knows if something like a sparco or bride seat would be good for someone in her condition. She has no strength to hold herself up, she has to be strapped in and upright. She's maybe 5'2" and 70 lbs. Do they make smaller sized seats for smaller people? Are the seats adjustable? Or would she be better off just getting an after market harness?

Any help will be appreciated. It is becoming more of a hassle to transport her for my mom and I'd like to see her be able to get out of the house.

Thanks
