    Quickie just released a different stye of adjustable upholstery on the GT which has more elasticity in the straps and has a neoprene type of cover. IMO it is better than their Jay Precision back upholstery.
    Thanks Scott ... I will look into this. The bottom velcro straps seem to be the same set up as their old upholsetry.

    While this started out as a way to give the top edge of the upholstery more support, there turned out to be other advantages that were purely serendipity. They include:

    - The backrest ears don't slide off the back post.

    - The resilience of the bungee's allows the back pad to spring back providing better lumbar support and controlling posterior pelvic tilt.

    - Because the lower straps are gone, I can now fold the back without removing the sideguards after only minor modifications.

    Not bad for around $7.

    Sweet! Your post could not have come at a better time for me, as I am specing out a ZRA and had just decided to go with the strap adjustable back.

    Where does one procure mini-bungee cord? A link would be much appreciated.

    What keeps the lower two bungees in place vertically where they loop the posts? The original straps look as if they had Velcro tabs to attack to the back, obviously the bungees don't. Any issues there? What are the yellow things?

    Even though the chair had 3 straps below the backrest ears, my ZRc has the standard Velcro adjustable upholstery. The tension adjustable by straps version has D loops on one ear with corresponding Velcro straps sewn into the opposite ear to connect them.

    They are 12" "Ball Bungee" canopy tarp ties. I bought them at Home Depot for $5.97.



    To get the ball off, I squeezed it in a vice until it cracked.

    The bungee's black fabric covering sticks to the hook Velcro on the back upholstery.

    There is a plastic sleeve on each canopy tie inside the ball. I used two of them on each bungee to reduce the gap between the portions of the loop on each side of the back posts so that the upholstery fits better.

    Mind you I have a 12" high back, good trunk control, and do not put much stress on this area. The lower bungees would probably not provide enough support on a taller back or with a heavier cushion.

    Does your back have holes for the back posts? The pictures look like fabric completely covers the back posts. My posts stick out about 1/2 to 1 inch and stabs me in the back...it really hurts. I'm fighting the place I got the chair about it now...I keep telling them there is no way quickie would do this...I must have a back for someone with a chair with handles.

    That upholstery has an opening for back posts with push handles, but also has a "pocket" sewn into the inside portion near the top which fits over the top of the back posts when no push handles are used.

    We searched for the pocket and could not find one.
    We have the hole with the openings and behind that a hole that goes most of the way to the top...we tried that opening but there was some stiching in the way where the metal screw holes were located.

    You are telling me the hole with the openings also has a flap? This is the quickie adjustable back?

    Update 2010

    To avoid derailing my first ZRA S2 thread, here are the mods I made to my ZRc (Series 1) to be able to fold my backrest down without removing my side guards. I no longer need to shim the panel my panel outward, but most of the hinge hardware needed significant reconfiguration and modifications in order to function properly...

    Thanks for the details. I ordered aluminum folding side guards with a solid seat pan, and a fold-down, lock-down back on my new AeroZ (to arrive soon). I'm hoping if it will all work right together because it's factory assembled . . . we'll see.

    You won't be able to fold the backrest down with side guards in place without extensive mods with the Aero Z locking back mechanism. See issues I experienced with that design here...
