Thread: ZR and ZRA Owners?

  1. #1

    ZR and ZRA Owners?

    I'm thinking of ordering a ZRA with 17" seat depth instead of my usual 16" depth. Can this be done without adding length to the frame?

    Depends on the chair you are using now. Top End for example, has their frame 1" longer than the stock Tilite. My ZRA with the same seat length is 1" shorter than My T/e Crossfire

    I ws shown, that we need at least a two finger space between the back of the leg behind the knee to the front edge of the cushion.

    "without adding length" to the frame, I think it's impossible.

    mine has 18 seat depth.

    Pat,I have a Quickie Ti with 16" seat depth. I was told that as rule of thumb,you should never have more than two fingers width from end of seat to the back of your knee. There is four fingers depth on my Quickie Ti and the same with the ZRA. My old Quickie GPV with 16" seat depth was a perfect fit as there was only room for two fingers between seat and back of my knee.
    I love the tight turning radius of my Quickie Ti which I've used since '03.I think adding an inch of seat depth will will allow me to have my body weight more evenly distributed,but I don't want to compromise my tight turning radius if possible. Will probably stay with 16" depth if pressure mapping is good.

    chriZ,you are probably right. I did have a '92 Quickie GPV that allowed one to add an inch of seat depth w/o changing frame length.

    I think the two finger distance came in with the steeper degree angle of the front ends. With the old Motion Designs(Quickie) rigids, the angle was around 75 degrees. So, there was no issue really of the back of the knees rubbing on the seat sling. Now with the angles much steeper, the back of the knee became an issue.

    I agree HW, 4 fingers is kinda out there for me also. If that's the case, you could more than likely go with a 17" and still have the same frame length.

    Out of curiousity, After the chairs you've had, you more than likely have the dump in your chair figured out. Being a C/8 (T/1), your dump is more like four inches right. Why not go with a ZR or TR rather than the ZRA. The COG and back is still adjustable and they are both much lighter. The TR is lighter than the ZR.

    I've had mostly non adjustable chairs for a long time. I have a ZRA now just for the fact that I was trying different cushions and wanted to vary the seat height to accomadate the different thickness cushions. It is a great chair, no complaints but I'm going back to a non adj. now that I've got that figured out. I've ordered a TR.

    hi Patrick,

    The TR's are a little bit lighter than ZR, TR's are made with 1" tubes instead 1.25" of ZR.

    But is another frame category, is a "box" rigid frame, and ZR or ZRa is cantilevered.

    Cantilevered frames is better to put in a car trunk, less space. IMO.

    Thanks Chris. I use a van and my wife has a Subaru so I wasn't too concerned about an open frame again. I like looks of the TR over the ZR or Crossfire was the basic reason I went with the TR.

    could you get a cushion with a longer depth?

    That's what I did, wtf. I questioned whether it was a good idea, but my seating specialist said it was a good way to get an extra inch without going longer in the frame. I wanted a smaller footprint so I went with it. I'm perfectly happy with it. Guess one wouldn't want to go any more than 1 inch probably tho.
