i have back problems also but have been able to play in the chair i posted i did make a couple of modifications 1st being a large guy i hand trouble getting in
and out of the chair because of the center steering/joystick holder i solved this by removing the 4 bolts and putting 2 hose clamp on front it now tilts
forward i can get in and out easy.then i bought a small clip board from the dollar store and slid it in the 1 inch gap in the holder clip part in srping holds it in
makes perfect mouse pad. working on keyboard mount next for now it sits on computer back.orderd a wall mount swivel out tv monitor holder holds up to 40 inch
will swivel monitor to 1 foot infront of joystick i think even if my eyesight fades i will still be able to kill you.
