Joan, I used a j foam for a few years and was never as comfortable as I am with a roho. I've never had one go flat fast, it is a sneaky thing. I find that I add air once every 4 to 6 weeks. It doesn't take a lot of air since it doesn't involve air preasure, its more air volume that makes it work. The quatro is even better because it doesnt let air shift when you lean the way the old one did. That causes an empty side and an over inflated side and I think that was the big complaint about early roho's. The j foam was stabnile but you needed preasure relief a lot. I've actually spent 32 hours on a roho without getting a breakdown from it. john -----Original Message----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [email protected] Sent: Wed, 24 Jan 2007 2:22 PM Subject: [QUAD-L] Pressure mapping
Thank you all for the input on pressure mapping. I have been somewhat reluctant to go to a Roh0 cushion as I am afraid that I will lose the stability of my J. cushion. We live on the side of a hill/mountain, and nowhere do I have much level ground. I have an Omega Trac wheelchair which is absolutely awesome and I can get around everywhere safely. By the way, I brought my Omega Trac on eBay. It was in Hong Kong and I paid $2300., which included shipping to United States. I had it sent to Teftec in Texas for an overhaul. They went over the entire chair, painted, put the new electronic system on it, and then had it shipped up to me. Ironically, the shipping from Texas was more than the shipping from Hong Kong! So back to the Roho cushion, how stable is it going over bumps and curbs and things? If it does spring a leak, how quickly does it go flat? I have absolutely no control of my upper torso, and have a chest strap that goes under my clothes to hold me in the chair. That is why I am somewhat concerned about the stability in the chair with the Roho. I would notice if the air was leaking out on one side or the other, but I would not notice if it were leaking out evenly, unless it went down an inch or so, for then I would feel it with the added pressure on my shoulders. Both arms are Velcroed to the armrests. Someone just brought up the problem of the vinyl cracking on the armrests -- I like to have my armrests covered in commercial velvet, we use spray adhesive and cut the velvet to fit. It makes them less slippery, and also not as hot in the summer. I am at least two months away from buying a new cushion, but I would like to explore my options now. Well, that's enough for this e-mail, I'll write more later. Joan, C4 1990. ________________________________________________________________________ Check out the new AOL.
