    That is what I'm afraid of. The chair I have now just barely fits through all the doorways in my house with no room to spare. I can't have castors that stick out really wide.

      If you need to get close to objects for transfers you may wish to consider the TiLite AeroZ w flip up footrests. In some cases you can get another inch or 2 closer for transfers and your insurance will probably pay for the Aero Z. The downside of flip up footrests is you can't use a Freewheel.

        Personally I would avoid a Q7 - 7000 series aluminum is not all it's cracked up to be by marketing (pun intended). Q7's ARE light weight, but achieving a few pounds of weight savings with compromised fabrication methodology (IMO) is not a good choice. I would rather have a slightly heavier, but sturdy, chair.
        I keep hearing that from the Ti Lite lovers but I just dont believe it until I see it personally.

        Ive had a Q7 for quiet a few months now and I dont know how much "sturdier" it could possibly be.

        What, exactly, is wrong with this aluminum?

        I do NOT like the caster setting (the "wide" setting) on my chair though. its dangerous and will kick you out forward at the slightest change of surface. Im actually surprised Sunrise Medical hasnt tried to be sued over this yet in fact.

        To answer the OPs question though, I have the 1.5X4" softroll casters.

          What, exactly, is wrong with this aluminum?
          When the Q7 was first introduced, it was presented as compatible with power assist, which puts extra stress on the front frame and caster mounts because of the forward rolling assistance (when going over obstacles such as thresholds). Then on CCC I saw rumors of cracked frames with power assist. Suddenly (and quietly about 6 months after its introduction) the Q7 order form added this note:


          I deduced that 7000 aluminum is not as sturdy as 6000 (at least when used in thin-wall tubing to save weight).

          Having studied strengths of materials (I'm an engineer), I know a brittle material breaks suddenly with very little (if any) warning, while flexible materials have some give to reduce/warn-of breakage (like an airplane wing or a bridge). I deduce that 7000 aluminum is more brittle than 6000. (These strengths are more complex/detailed, but I won't post a strength-of-materials primer.)

          One significant advantage of titanium over aluminum is that titanium has no bending fatigue (it flexes repeatedly with no molecular damage). Aluminum experiences bending fatigue, thus the 5-yr life expectancy on wheelchair frames, and 30-yr? life expectancy on airplane skins. So, titanium frames don't wear out; 6000Al frames flex but eventually wear out, and will break under heavy stress; 7000Al frames flex and wear out, but break suddenly under moderate stress. If 7000Al were fabricated the with same thicknesses as 6000Al, they would probably perform equally well, but then 7000Al would have no weight advantage.

          So, without math, that's exactly whats 'wrong' with 7000 series aluminum in wheelchair frames. It's not wrong, just less sturdy than 6000Al frames (IMO).

          My guesses are that manufacturers are gambling most users will not over stress their 7000Al chairs, and Sunrise hedged that bet by not approving use of PA on the Q7.

          My AeroZ1 (with wheels) is about 5.5# (30%) heavier than a comparably configured Q7. Weight is not an issue for me, and power assist is likely in my future (my AeroZ is reinforced for it). So that's why I'm sensitive about the Q7.

            I am gonna chime in here. As I have a Q7. ok first off let me say I am lucky if I have a months use on my Q7. I have front caster housing flex. and stress in the metal on mine. so maybe the Q7 is for not so active users. my insurance is sending me back in for another seating eval. the Q7 is a nice looking chair. i'll give it that. but for me its just not working! frame stress and caster housing stress is not what I call good metal. to each their own. for me I will not own another quickie chair as long as I am alive. frustration does not even explain how I feel.

              So what is your defintion of "active user" then? I work a 40 hour week job every week, Im out and about all the time using my wheelchair. im in my chair about 14 hours a day. I just got back from a 7 night cruise to the Virgin Islands. Ive hunted out of it, trained my dog out of it and about anything else and have not experienced a problem yet. I would classify myself as a very "active user".

              It may break in half tomorrow but I just dont understand these problems you are having. I have not yet experienced any of that.

              What exactly is frame stress and caster housing stress? Could you have possibly gotten a "lemon" ? I would be pissed off too.

                I could have gotten a lemon. I donno. trying to get quickie to make it right is like trying to pull a lions teeth while he's awake. I have just given up. on my chaster housing the metal under the paint is stressing and parts of the frame is stressing. I took it to a buddy of mine and asked him to look at it. and he said yes the metal is stressing. he's a metal fabricator. you might be right I could have just got a lemon. oh well! I have been fighting my DME too long.its just not worth it anymore. it happens this guy I spoke to while waiting at the dme said his frame snapped and broke. he's been waiting 6 months for sunrise to fix it.

                  I sure hate to hear you are having so many problems I remember how excited you were when you were waiting to get your new chair.

                  I have heard that Quickies "customer service" is atrocious for sure.

                  Hopefully they make it right for you

                    good sign of metal stress is "spider webbing" in the paint

                      my doctor and case manager and OT are pushing for the ICON witch is a thing.
                      bob my paint spider webbed. its sad.
                      I lost so much weight too so now the seat base don't even fit. my Ot and I both agree I need an ajustable seat base. plus my body is constantly changing so what may work to day may not work a month to six months down the road. sad but true! so we'll see. go to my new seating eval in june. Its been a long road. I hope it ends soon.

                        Thats what I have now and I absolutely hate that kind of footrest. My feet don't stay on them at all they always fall behind the footrests.

                          You may want to try using a calf strap behind your calves and maybe slightly raise your footrests to plant them more solidly. I used to have a Crossfire w angle adjustable footrests which did a good job on keeping my feet in place. I know next to nothing about Q7 but that the few I have seen had caster wings which stick out and would get in my way.
