    Solid seat measurement question

    My ZRA is 17"x17+1. I thought it my dealer had ordered a 17"x13" active ADI back. Since day 1 the back digs into my ribs. I told the dealer, he said for $75 he'd adjust it. I was a part-time M.S user, I've been using a pillow on my lower back whenever I use my chair for long periods of time. I just came home from a 3-month hospital/rehab stay after 3 back to back strokes. Now a full-time user, hemiparesis/partially paralyzed, PT told me I need a taller back. I called ADI to verify what was ordered for me and sure enough the dealer ordered the wrong thing, he ordered a 16x10" active ADI back.
    I'm looking at the Roho Agility Mid back, I like the idea of an adjustable air back and sides that support me but I'm nervous because my current ADI's 2 1/2" set up digs, I figure that's because it's a 16" on a 17" back, but I don't see a 17" back offered by Roho, I see 16" or 18".
    I think my dealer also seems to have measured for a cloth not solid back. My COG was set based on the middle of the chair, but w/my back on it pushes me up a few inches and my arms were nowhere near the center of the wheel. A dealer at my SNF took pity on me and moved the COG up so my arm is in the right spot, but now I only have 1 3/4 inch before I hit the center bar, much less room for brakes or the tire hitting my casters. Will I have room for a 4" deep back? If the back can be ordered in 17 or even 18" I think the "hugging part" will go around me. If it has to be 16" it will just dig into me even more and I'd lose more seat room.
    Thank you so much for your expertise. I can't afford, in more ways than one, to have this get screwed up again.

    Find a PT seating specialist in your area, try and get a recommendation from other wheelchair users in your area. They should be able to adjust your chair and get you a back to trial from the DME before you go with it and share their expertise as far as what backs may work best for you. Yet to find a dealer DME that finely adjust chairs well.

    Thank you NW-Will, that's an ATP right? Other than booking a seating eval. in a hospital would you suggest another way of going about finding a seating specialist?
    The ATP I called asked if I had a letter of medical necessity written for a chair back/cushion. While my PT recommended a taller back and Roho cushion, she said a doctor wrote up letters of medical necessity... I thought PT's were doctors?
    My first chair took me down the seedy path of kick backs from the person writing the letter and the DME company. I don't know how it's supposed to be done.

    PTs are not physicians. Some may have a doctorate in PT (DPT) but that is not the same as an MD or DO.

    The physician must sign the letter of medical necessity (justification), but normally the PT or OT who does your seating or chair evaluation actually writes the letter for the physician to sign.
