1. ## Ordering wheelchair... Please comment on measurements

I´m quad, c6/c7, 6"1 and 165 lbs
After measuring and remeasuring for the umpteenth time based on the chair I have been using. I have settled on the following specs for a melrose wheelchair that I plan to order shortly
Rear seat width: 15.5" (no taper)
Seat depth: 16.5"
Front seat height: 19"
Rear seat height: 15.0"
back height: 15.5"
Footrest Width: 10.5"
Seat to footplate: 16"
Overall frame length: ??? I don´t know how i can get this.
Front frame angle: 85 degrees or 80 degrees
COG: 3"(not sure)
Front casters: 4" x 1" alloy
Rear wheel: 25" Spinergy LX
Side guards: Aluminium
Wheel locks: Aluminium scissor lock
Handrims: Vinyl
Front forks:Std.
Camber: 3º
Please comment on the measurements, parts and options. All help is appreciated.

2. which Melrose? Since you're not sure of COG, I presume one of the adjustable ones.
To get overall frame length (when it's not provided), I wrote a spreadsheet using some assumptions and trigonometry. For my chair my calcs were very close (calc'd=32.35"; actual=32.2")

Attached is my spreadsheet. Unless you know trig (e.g., radians, degrees, tangent) and Excel, it's very hard to follow. You need to input the value for the light-blue cells; the white cells are calculated.

3. I nominate this spreadsheet for a sticky.

Good work.

Everything appears reasonable to me. (Personally I prefer hub locks, softroll casters, solid seat pan, and Natural Fit handrims, but that's just me.)

7. 4" of dump? Is that ok, guys? Maybe consider ergo seat? I don't know - I have 2.5" without ergo.

I've been looking for someone to convince me of the benefits for some time (and remember I am not only an end user, but a full-time SCI seating therapist). I still have yet to hear a convincing, medically-sound, rationale.

Top End was the first to offer it and I think TiLite, Colours, and others started offering it because Top End had it (who marketed it like it was the second coming of the Herman-Miller Aeron office chair).

I think the ergo seat has been around long enough, that we would see it on a lot of end user's wheelchairs if it worked as well as advertised.

9. 4 dump with 3 COG makes the chair tippy?

Depends the backrest height and the backrest angle too in how tippy will be the chair, but a 4 dump with 3 cog almost in all chairs will be tippy.
