    Pressure gauge for roho

    Do they make the pressure gauge for setting up a roho correctly? My spinal unit seems to think there is one but I can't find one anywhere on the Internet. This business of putting your hand under the cushion to make sure its inflated correctly is ridiculous in my opinion. This cushion has been around for years, it's about time they had a failsafe way of setting it up probably instead of guessing which is what you are really doing since you can't see your hands under your arse

    I guess failsafe would be to go in for a seating clinic and find how much air minimizes the pressure.

    But, gain/lose some weight, and that changes. Extreme temperature difference? Changed.

    On the other hand, knowing that the "proper" amount of air is just enough to keep you from bottoming out, and unless you want to carry around the pressure pad from a seating clinic, measuring with your hand is indeed the best way to do this.

    My 2 cents. I switched to a ride cushion :P

      Given the same air pressure in a Roho cushion, the distance between your ischial bones and the chair platform will be different depending on your weight and how much surface area your bottom has.
      Nevertheless, I agree there should be a way to set the thing up correctly, and to check that it remains correct. In particular, an alarm when the thing bottoms out would be very helpful ... perhaps electrical contacts within the cushion between finger top and base?
      We presently have problems with a cushion that leaks only when it's being sat upon, so I haven't been able to locate the leak by dunking the thing in the tub.

        Richard........ over inflate the cushion tremendously. Then stick it in water, you should find it.

          I guess I was afraid of damaging it... but overinflation wouldn't put any more pressure in it than sitting on it! Duh.
          I'll try that. Thanks.

            use blood pressure cuff guage....will tell you press in cush...pull guage off cuff, stick rubber tube from pump between guage and valve

              overinflate, then rub with dishsoap/water solution - 1:3 -- then the hole will blow bubbles. That's how we find the leaks on tires in the shop.

                not sure if that is what you are looking for
                And only $120 for the basic model.

                  I think that gauge will tell you if your cushion is losing pressure, but it won't actually tell you when the cushion is set up correctly unfortunately. If roho pooled their fingers out of their backsides, they could come up with something quite easily I think. You just need something that attaches to the valve when you are sitting in it. You could turn and seal body weight and then let it determine when the pressure is correct. It would probably cost quite a lot of money but what price do you you you put on your health?

                    Just found it says it replaces the finger under your arse method. It doesn't go into enough detail of how it actually knows when the cushion is inflated enough. And why aren't roho selling something like this?, probably because it isn't as good as it says it is.

                      The secret to the Roho cushion is not the pressure inside the cushion (which will vary with the butt and body weight) but the amount you sink into the cushion. The more you sink in, without bottoming out, the better the pressure distribution away from the vulnerable bony areas like the ischiums. There was a little fill gauge that Roho used to provide, but it never worked well, and much research has validated the preferred method of over inflating, then deflating slowing until you have 1 fingertip of space plus 1/2"-1" "wiggle" between the ischial bone and the wheelchair seat.

                      The Roho is a "high maintenance" cushion. If you don't have the patience or cannot make a daily fill check part of your routine, or if you have a lifestyle which would subject it frequently to risks for puncture, then it is probably not the right cushion for you.

                        Found & fixed 2 small pinholes in the fingers today! I should have read the repair instructions before - they say to overinflate it so much that the 4 corners touch.

                        I don't see that a pressure monitor would help much at all; particularly with the quadtro select, which has 4 sectors. The actual pressure differential between an inch of clearance and no clearance at all is probably pretty small, and as KLD says, the pressure varies a lot from person to person.

                        As far as pressure distribution goes, I sometimes see a row of pink marks on my wife's thighs corresponding to the Roho fingers; odd, because we're following the instructions for proper inflation (so I think!).

                          w00t!!

                          I get the line across my butt with my ROHO - I figured out why today when my snap on my cover came off and smacked me in the rear. When I'm at work, I slide forward in my seat which causes my cushion to roll up in the back. The bottom rubber actually rolls up and hits me across the rear.

                          Keep a close eye on how she's sitting and any movements shes' doing during the day. It didn't dawn on me til today, and it took a snap blowing to show me why. Later in the day, I lifted myself back and put me on the cushion right, but then slid a little and ended up on that rubber piece again. I know in my case more dump will help with the problem I have. But, that's the next chair.

                          As for proper pressure. Once a week or so, I will sit on my hand and wiggle the fingers to make sure I am still at 1/2" between my rear and the bottom. I don't think I've put air in it since Sis was here in April. I am rough on my cushion too. It shoulda busted by now based on how I treat it.

                          I guess I am due to wash my cushion & cover.... nah. I'll wait til after camping this weekend.

                            I have found my roho's to be amazingly durable. When my cat was little she actually used to sleep on one of them. We would go to bed and she would climb over in my chair and sleep next to the bed.

                              DITTO....my cat actually tends to knead on my Roho...I try to keep her from doing it, but alas, she's still a kitten and she kneads on anything soft and cushy. I am quite happy that Smokie hasn't taught the new kitten Talle to knead with her razor claws on my cushion AND that Smokie's claws have yet to puncture my Roho. I know it's probably just a matter of time, but I have been REALLY rough on it...They are quite durable. YEAH!!!

                              RD: pressure in them, it's VERY individual, the only way to really guage the "proper" pressure is to figure out what is "proper" for yourself and do what someone suggested with the blood pressure guage to check your pressure, however the pressure would be different for different people.
