    Seat taper: I did not spec any seat taper.

    9 inch footrest specs: My feet, when together are just under 9" wide. I was thinking that having them confined would keep them more stable. Right now my feet slide all over the place. Of course, much of that is due to the fact that the footrest is about 1/2" too low. Do you still think I need an extra inch? This footrest width measurement is definitely one of those things I'd like to hear from those with experience about.
    Sorry, I saw all the taper references and thought, for some reason, you meant seat-frame taper. I do think you should be careful about getting a footrest that is too narrow. As you probably know, TiLite measures this between the frame a couple of inches above the actual plane of the footrest, so the distance at that plane will be a little less. From my experience that "less" equals somewhere between .5" to 1". So a 9" footrest may actually be 8.5" or less at it's narrowest point. And of course that can be the widest part for some shoes (the sole). I ordered my TR3 with a V-front and a 10.5" footrest (actually measures about 9.5" at the top of the tubing curve), and I have a medium width, size 8 1/2 shoe. I do understand the need to keep your feet from sliding back and forth; I hated that on my first chair. Just be careful if you plan on using wider shoes or boots. My problem is I go with just socks often and also use shoes at times.

      I should also note that the difference between the footrest width measurement and the width at the narrowest point, at the foot plane, can be more or less depending on your seat width and front frame style. With a V-front, the greater the difference between seat width to footrest width--the steeper the "V" angle--the more you lose footrest width in that couple of inches below the actual point of measure. In other words, with an 18" seat width and a 9" footrest, you'll probably end up with slightly less than 8" at the bottom, most narrow point (excluding the curve which can make things even narrower). With the Tapered Style front end there shouldn't be much difference because after the inward frame taper the front end tubes are essentially straight down and parallel. The diagrams below are from TiLite's order form.

        Why frame length added and not seat depth added? I think you need to increase your seat depth, not frame length. (I believe someone else already mentioned that, but wanted to bring it up again)

          Ala:
          I emailed Tilite with the footrest width concern:
          I asked them what measurement I would have to spec 2.5" above the footplate in order to get a 9" wide actual footplate. I suggested 10.5"
          She replied:

          "If you are trying to get the footplate to 9" that would be about right. You can also make a request that the footplate be 9".


          So, I will definitely make a request for a 9" wide footplate... and let Tilite figure out the measurement at the bottom of the frame (before the footrest bars).

          Lin:
          The reason for the frame extension is that the cushion will only measure 18.25" in depth. So I thought rather than having the seat material exceed the cushion,
          it would just end about where the cushion does... and still be able to get the length I need.

          stumpybushman: Thanks for sharing your chair.

          Brianm:
          I am definitely on track to reduce the width to 17" from 18". My hips are just 14.75" so, I really do think I can shave off a cell on my roho cushion.. right now I have
          9 Cells across (16.5") and if i make it 8 cells, that will be 14.75" .. which will pretty much match my hips exactly. I figure, if I add an inch 2 extra space
          ...17" will give me more than enough room for comfort. I suppose I could consider going to 16".. but that might be pushing it. I am going to ask my supplier to let me demo a 17".. and if possible a 16".
          I am considering following your advice about increasing the dump and lowering the rear seat height... at least 1/2". The sling seating does tend to bend after a while... but I suppose it's not the right way to adjust height.

          All:
          Also...after many comments about the footrest height... I went out today and had the bolt fixed... and finally was able to raise it up 1/2". Much more comfortable. And healthier.
          Thanks everyone for your feedback.. it's invaluable.

            .
            I prefer to have a little slack in my sling. I loosened my seat sling to create a nice little bucket shape. Others do this too. Like I've said before, a person's rear end isn't flat, after all. It makes me feel more like I'm sitting in my cushion rather than on it. If you like this also, do it. It's not the "wrong" way to lower your seating position, if it feels right to you. Also, many of us do not like a lot of dump. I don't like more than a 2" difference between front and rear chair heights. Make sure this is what feels good for you, not just what others are saying.

              How about moving to a 19" depth cushion? Have you tried one out? In the photos of you in your current chair it really looks like you need more seat depth.

                As for the suggestion of going to a 19" cushion, keep in mind he is changing the angle of the front of his chair also.

                We all have what we like that may differ from others. For me, if I get too much seat sag my back hurts. When I have them tightened up and my back immediately starts to feel better. I use the cushion for a "dish" for the butt. I have found that with the tension adjustable seat straps they need tightened every couple weeks for the first few months when new. I still think a TRA may be a great way to go, but also don't think you'd regret going down a little.

                I think it is a great idea to try and get both a 17" and 16" chair. This chair is a lot of money and you use it all day, it makes your life much better to have it fit you the best you can.

                I would ask for a clarification on requesting a 9" footplate. My footplate doesn't go all the way to the inside of the bars, the actual plate is smaller than 11", but the width inside the bars is the 11" I ordered.

                I would think an 18.25" cushion would fit the 18" seat just fine in the front by simply letting a 1/4" hang off the back. I have a 17" cushion on a 16" deep seat and it is flush with the front, hangs over in the back.

                Excellent to hear about fixing your footrest height.

                  I completely agree, thats why I ask if its something he's tried. What works for one person doesn't work for the next. From the photos though it looks as if his depth is much too short for his body. It may be his preference and what works best for him, or he may have never tried any more depth.

                    Togs, here's some screen captures of your existing chair. A few guessed dimensions are a bit off (e.g., bottom frame tubing); I will tweak them some. Sorry I'm not further along:

                        I've overlayed your current and new chairs within CAD. I'll make a movie very soon so you can see the comparison better. Meanwhile here are two screen shots of your new chair:

                          Here is a video. As you're watching, check the measurements for correctness. TiLite doesn't publish how they determine caster placement, so I guessed. The new chair is green:

                            Did Tilite change shape of bar along backrest? I see your drawing is mult-angle. I did just receive a new chair a few weeks ago. Has bar like your drawing. However, few years ago when I got my TR3, that was a single oval. As for overall dimension of chair, I do not sit specifically snug everywhere. My primary reason for that is, I do NOT want the chair doing everything for me, that my body may be able to do. This in course of hoping I will be able to walk There are pros and cons to all of these things. Make sure you have evaluated all of them and made your best decision.

                              The standard backrest bar on the TR3 is now oval. The 4" backrest bar (TRSB12) is the old shape (like I drew), which TogsT8 indicated he might want, and which I ordered on my new chair. (My drawings are not perfect, they're for comparison of primary dimensions of a current versus proposed new chair.)

                                You should look at adjustable chairs. If your current chair had one or two measurements that needed tweaking, it would be one thing, but you're so far off that there's very little chance of you "nailing it" with another custom, fully welded frame.

                                Why would you want to sit in a chair that's over 2" wider than your hips? Put two books on either side of your hips, and measure in between - that's how wide your chair should be, and you should get side guards.

                                Seat to floor is a number of inches too high, and your seat looks like it's way too flat.
