    Photo and first impressions of the chair

    Apologies for the delay in posting the photos. The wife has been extremely busy with work. This photo was taken just an hour ago. I have been using the ZRA since yesterday and had backache. It has disappeared though.

    The backrest is in its original position. I could be mistaken initially for assuming that it was 90 degrees. It looks leaned back. There is some significant play of the backrest when locked in upright position. I am also watching out for signs of the backrest problems other CC members are facing with the ZRA S2.

    I am sitting higher up here as compared to the old chair due to the 2" Stimulite Sport and taut seat upholstery. This will need some getting used to. The cushion, although firmer than I had expected, is comfortable. I don't need to shift my weight that often. The 3.5" dump doesn't feel extreme. I think I can go down to 4" and still comfortable. I may also want to lower the back seat height by another inch from 16.5".

    After SCI_OTR suggested that I should go for longer vertical struts, I put in a note for one with medium-length but this looks short. Nevertheless, I don't think I need to raise the RSH. I am comfortable as it is and am thinking whether I should move it up another 0.5" to go for the 4" seat dump.

    The chair is very stable with 2" COG. There was no tippiness going up a 1:12 gradient incline. I may want to go for 2.5" at a later time. I am also happy with the 85 degrees front angle and the footrest with ABS cover. My legs are tucked back, very comfortable and I am sure they won't be able to slip off the back edge.

    The following are some of the issues with the chair. The anodized aluminium push rims are slippery. I will be wrapping them with the racket tapes to see if I can get a better grip. The aluminium sideguards are great at keeping my pants away from the wheels but they also extend beyond the wheels and that impedes transfers. The brackets are already moved to the 4 frontmost holes. I am looking to have them profiled to the wheels. Likewise, the arm rests are extend out too far to the front. I would prefer them to be 2" shorter for transfer without having to remove them.

    I have 2 questions. SCI_OTR, you mentioned about posterior pelvic tilt with my previous wheelchair. I have a feeling that that I have the same issue with this new chair. Any comment and solution to that?

    The other is that the left caster floats a little when empty but all 4 wheels contact the ground and doesn't seem to pull to one side when I am seated on it. Is there any need to correct this issue?

    Otherwise, I am generally happy with how this chair has turned out. Thank you everyone for your comments and advice. I am going to be even happier when I have it dialed in for that perfect fit.

      the guy in the chair doesn't look anywhere near as happy as the guy in the avatar.
      <sigh> I hope Ti quality improves. Sure makes a guy wonder how they can charge so much. So glad I splurged on my Lasher.

            tooley - I was overwhelmed by the new ride, the good and the issues that came with it. Quality could be better but this rigid is very responsive as compared to my previous folding. But then again, this costs twice as much as the folding. I will be as happy as how I look in the avatar when all the nitty gritty are resolved.

            fuente - Thanks. Yes, I like this cushion. Hopefully, when it breaks in, it will be even more comfortable. I cannot even remember the last time my buttocks felt so pampered.

              "The aluminium sideguards are great at keeping my pants away from the wheels but they also extend beyond the wheels and that impedes transfers."

              I may be corrected, but TiLite has two generic side guards, small and large. It appears to me you have the large. The small would have stopped shorter, but they also would not have went up to the top of the wheel.

              Why not just pull the side guard off when transferring?

                  Peter, if you don't have a grip problem, I'd consider wearing gloves for pushing when you are outside. I use very lightweight batters gloves, and don't even notice them any more. Inside, I don't find the slickness is enough to bother me. If you push using your hand in the same position as in the photo, you might find it easier if you place your thumb along the top of the push rim for a bit of extra "grab".

                  Back when I used armrests, I used to just lift them up and rotate them out of the way for transfers. It *is* a nice looking chair!

                      Great looking chair, and looks like a good fit. Takes awhile to get real comfy. You'll get there. I don't have an answer for the side guards. I second what Brianm says. I ordered the small side guards and they were too short; came below the wheels. Then I had to order regular ones. But I've been able to move these back far enough. But I have the ZRA1

                        jackson - Have you taken delivery of your chair? Should arrive any time soon.

                        Lenny - We can meet up to ogle each other's chair after the CNY season?

                        Aaron - Thanks. Would love to check out your handcycle. That could be my next "project".

                          toto - You have got very sharp eyes. Done! Thanks. I see that you learnt about the yellow cover from fuentes.

                          Brian - I got the large ones. Other than removing the sideguard, I also need to remove the arm rest before transferring. It is such a hassle when I am out as the wife has to remove everything before storing the chair in the car boot. I think we both need to get used to this routine, so different from my previous chair which was basically fold and go.

                          fuente - Looks like drilling holes is a simpler task than profiling but I will need check if the back part of the sideguards are rubbing against the side of the backrest.

                          Don - I wear gloves and it is slippery as well. My leather gloves came with rubber pads for the palm but they got worn out pretty fast and they are very expensive. So now I just use them without the pads. I can't grip the push rims with my thumbs as I don't have strength there. As for the arm rest, I need it to push myself into the car. Need to learn how to do it with this as it flops around when not locked in and too long when locked in. Haha. Thanks for the compliments.

                          jackson - Post up pics when they arrive, hopefully you don't take as long as me to do that though.

                          Lynne - Thanks. I am slowly getting comfortable in it. Need to do a few more adjustments as I go along. I will either profile the side guards or drill holes as fuente suggested. Meanwhile, I am just enjoying the new chair. The best of all, it doesn't creak! The poly casters are uncomfortable on tiled floors though.

                            It looks like your feet may be tucked a little further back than they need to be. If you bring them further forward on the footrest, will your knees be too high or splay out? If so, then your footrest should be lowered a little bit (consult owners manual or search this site for the proper technique to do this without frustration. You can also get rid of that floating caster in the process).

                            I have a question. How much of a gap is there between the back of your knee and the cushion? It is hard to tell from the pic, if there is no gap and tuck your feet that far back, then your pelvis will tend to be pulled forward.

                            Also, when you put your hands down to your sides, where is the hub of the rear wheel in relation to your middle finger?

                            Looking at the pic of your posture in the other chair, you are already sitting better. A few adjustments and a few more posts to go, but it looks like you will get there.

                              The feet can be in a more forward position with just a slight difference to the height of the knee or splaying out. It just felt more comfortable with them that far back. Do you think moving the footrest down another 1/4" or 1/2" could make it better? I am a bit reluctant to do adjustments for the floating caster if it will not pose any problem. You mean to say adjusting the footrest height will eliminate that problem?

                              There is about a 2.5" gap between cushion and back of knee. With the current 3.5" dump and backrest angle, I feel like falling forward and compensate that by sitting slightly forward which makes me slouch. I have not adjusted the straps yet. What would you suggest?

                              Sitting up straight, the middle of my middle finger is at the center of the hub. I understand that the tip should be touching the hub. Please share the logic to this.

                              Other than those issues, I am almost happy with the wheelchair out of the box. It is like what I have expected except it is not as light as I had anticipated.
