      Take your time looking it all over. Compare it to the order form line by line. Do not just presume it's right. Even take along your tape measure. After you've checked it all out, take it for a ride before you sign. Remember once you've signed for it, you get to live with it at least five years, so take your time checking it out.

      I love my AeroZ - hope you do, too.

      • I received my chair last week. The DME spent about an hour with me fine tuning some adjustments. I had him lower the rear seat height so I'm more "in" the chair instead of "on" the chair.. it felt forward tipy before. I would considering even going a bit further.
        He also moved the wheels forward to make the chair more tippy. I can get into a wheelie now if i lean back and move the wheels back and forth some. I feel like I may end up moving that a little bit further forward, dependin on how my learning progresses. Currently I cant seem to pop up the front casters if im already moving forward, such as to try to lift them up over a bump in the sidewalk. I have to stop, lift up the casters, and then move forward again. I'm not sure if that's just a learning curve thing though, so I will give it awhile and see how I do.

        • Looks Great! Enjoy

          Popping your casters up on the move may or may not come to you with practice. I cannot do it, but I have dysmetria in my arms (jerky/unstable movement).

          • ~Lin, elarson, Jim, and (last, but certainly not least) chasmengr -- you beautiful bastard -- thanks for your continued help.

            Believe you me, I will be going over this thing with a fine tooth comb, should I actually ever get it. I don't remember what all I said last time I was here -- I know I could just go back and read it, but meh, haha -- but something is up with this process. I don't trust this people one bit, but so much time and effort has gone into this that I am at least going to see it through to the end. If it's all correct, good. I'm not assuming that will be the case, though, and I'll tell them to shove it up their asses.

            My first appointment was the last week of May, and they told me they'd have it finished and delivered by the first week of September. I knew there was no way that would happen, but that's fine. It's now November. At one point, the woman I've been in contact with had something happen -- my presumption is surgery of some sort, chemo, or had a baby -- and apparently has been working from home. She contacted me and said she would send me the final version of the order form to approve before submitting it. A month went by. I contacted her (I've been doing it all via email so it's on file) and asked what was going on. She wrote back that she was waiting to hear from me that everything was OK; she'd order it now. I replied saying I never got anything. She basically said, "Oh, whoopsies! I thought I sent it."

            So, there was a month in total wasted. A similar instance happened after that and another week and a half were wasted. It was then she told me that she had been working from home and having emails forwarded there, and she wasn't getting them all. Well, if you know there is a problem and you aren't getting all your emails from work, stop forwarding them. Or double and triple check with people.

            I don't mean to take it all out on her, because she's been very nice and the only person to really answer my questions, but it's pretty indicative of how this entire process has gone.

            And thus commences rant # God only knows about this.

            On a final note, congratulations, k4olin! I'm glad everything seems to be going well with your new chair. One question: Matte black and the "Black Lava" are not the same color, correct?

              • yup.. i had ordered matte black, but somewhere things got confused and i ended up with the shiny what i think they call "Wet black".
                but i wasnt gonna grump about matte vs. shiny when they had gotten everything else right

                • This weekend I moved the casters to a different hole in order to raise the front a touch.
                  And i lowered the rear seat height as low as it would go.
                  And then adjusted the brakes accordingly.
                  Also lowered the back a bit.
                  It feels a lot better now. Like I'm more "in" the chair.
                  Though the cushion does still sometimes feel too close to the backs of my knees.. but im trying to get used to that.
                  I know that a lot of the problem in getting the angle right has to do with how overweight I am..
                  I'm working on that! and having mobility will help!

                  now i need to resolve an issue with the sideguards being about an inch too short.. but im working on that.

                  I also have to learn how to grab the handrims without killing my hands. I have not figured out what exactly im doing wrong. Hopefully this is just a learning curve kind of thing.


                  This is my first chair.. so i'd love any feedback or tips

                  • Looks like you could actually use a little lower RSH. Is it possible to make any changes to get lower? Seems as if you were measured wrong if not.... And I can tell you from personal experience the extreme difference it makes once you're finally low enough. In my current chair I physically couldn't get low enough, and then I tried out an Icon and finally could. I can't wait to receive my Icon. (which is becoming an epic saga, horrible horrible service from NuMotion and I didn't have a choice of the DME due to voc rehab)

                    What issues are you having with how you grab the handrims? It might be the type of handrim itself. For me I need natural fit LTs. The regular size is too large and hurts my hand, and using handrims without thumb rings hurts my thumbs at the base where they connect to my hand. But I also wear wrist splints that affect the way I grab the rim.

                    • Ive got the height set on the lowest possible setting. so there is no way I know of to change it. Though someone else may know of some kind of hack to lower it further.
                      But I agree. I sat in it with no cushion and bring that much lower felt better. So I may need to figure out something to keep most of my butt practically on the seat webbing but angled up to keep the knees higher.
                      Otherwise im guessing I'd have to change from 25" to 24" tires. Which isn't in the budget right now.

                      The measurements must have been quite off as it was originally set about 2.5-3" higher than where it sits right now.



                      Handrim wise. I think the problem is my instinct is to fully grab that wrapping my fingers all the way around them. So then I often get them squished when one of the hand rim tabs comes up while I'm trying to initially grab the spinning wheel.

                      • When I needed to lower my RSH a bit more, my PT provided an adjustable cushion, and we adjusted the rear a bit thinner and the front a bit thicker: Comfort Company Standard Adjuster. I was able to lower my RSH about 1".



                        Switching from 25 to 24 wheels will likely decrease your pushing efficiency. It sounds counter-intuitive, but when you study the details, it's true:

                        The rule-of-thumb 'ideal' of fingertips touching your axle was derived from a research study (attached: Seat-Height propulsion effects highlighted.pdf) that identified the best elbow-angle range for pushing (ie., 100-130 degrees with good posture and hands resting top dead center on the push rims). Switching from 25 to 24 wheels will lower your RSH 1/2" and lower the top dead center of your push rims 1" because 24 wheels have smaller diameter push rims than 25". Thus your shoulders would be 1/2" farther away from top dead center of your push rims (in the pic 16-1/2 for 24 versus 16 for 25), increasing your elbow angle, which looks too obtuse already in your pics. Only accurate measuring of your elbow angles would reveal the facts.

                        • So I think what you're saying Chas is
                          A. based on where my arms are hitting... wheels should stay at 25"
                          B. based on where my arms are hitting RSH is correct or already lower than optimal
                          C. i should try to adjust my cushion to get the air to distribute lower in the back (i have a Varilite Evolution.. so i can let it air up and then sit down and let the air out some while really putting weight on my butt and not my legs to see if that helps.

                          • A. yes.

                            B. No. I'm guessing from the fingertip-on-axle rule-of-thumb that your RSH should be lower, but measuring your elbow angle is the true indicator (100-130 degrees).

                            C. Maybe. Lowering your RSH by thinning the rear of your cushion (not changing wheel size) should be considered if your elbow angle is too obtuse (i.e., greater than 130 degrees). I doubt the Evolution will allow uneven inflation, but just letting air out may thin it all over; a folded towel beneath the cushion's front could then raise the FSH back up. (I have no experience with the Evolution.)

                            BE CAREFUL: I forget whether or not you're susceptible to pressure sores - be very careful if you are - consult a seating specialist - get mapped again with the thinner cushion. (I am not susceptible to pressure sores.)

                            • When I couldn't get my rsh lower, I went UP to 25" wheels. My reasoning was if I couldn't get any lower into the wheels, bringing the wheels higher up to me (relatively between the axle and my hand) would assist. I posted a few different times here with my theory, intially people disagreed later people agreed and after I went for it I was GREATLY pleased and will never go back to 24s. And in fact since then I've also seen others here on the forum make the same change for the same reason with good results. So definitely do not drop down in wheel size. While that drops your actual rsh, that makes the issue of wheel access for pushing efficiency WORSE. I've seen that happen to a member here, I can't remember her user name but her real name is Mimi. They dropped her to 22s because her rsh couldn't get low enough in 24s. Later, she got a new chair and went with 25s like I did and has been MUCH happier. You have to remember that the correct measurements are all for a reason, like rsh for pushing efficiency. Purely dropping rsh for the sake of dropping rsh without considering how it will affect your pushing efficiency is going in the wrong direction.

                              I also use a vicair cushion, the vicair vector myself and similarly much lowered the back and raised the height to increase my dump and get lower in the chair. I succeeded in getting as low as possible, probably 1" off the sling while being in the most comfortable cushion I've used so far, however I move around in my seat frequently, which shifts the air cells around so sometimes I have to lift myself up and punch things back into position or transfer out to reshape the cushion, because its made up of a bunch of different sections with individual air cells inside. I'm getting a stimulite pediatric cushion with my new wheelchair which I'm anxious to try out.

                              You can definitely try out lowering in the varilite and a towel in front. But yes if pressure sores are a concern you need to consider this! If it works and helps things out, you can purchase foam to raise the front of the cushion. Varilite I believe even sells a foam wedge, but its greatly overpriced. I'd get some firm foam from a sewing/craft or upholstery shop and cut it how you want (electric carving knife, or even kitchen knife depending on the type of foam and going slowly) and use some stick on velcro to attach it to your seat and cushion where you want it.

                                Really nice looking chair!!! And so good that you are able to make the adjustments. From my limited experience, I am surprised that 25" wheels were ordered for you. I was told that fingertips should easily touch QR button, and yours are significantly above. Perhaps someone who is in the opposite position would trade parts with you?! I think the Natural Fit handrims would be far more safe for you if you are bashing your thumb or fingertips.

                                chasmengr, you seem to know a great deal about these things and I really appreciate your posts!
