Click to zoomWHILL Model C2 High Back Seat
A 20" high back seat that turns a standard Model C2 into a high back chair. It adds 7" of seatback over the standard seat, adjusts through a 21.8" to 26.5" back support height, carries four lateral adjuster pads, and bolts to the existing frame.
A 20" high back seat for the WHILL Model C2, adding 7" over the standard seatback, with a 21.8" to 26.5" back support height and four lateral adjuster pads. It fits an 18" or 20" seat.
What stands out
This is the cheaper of two ways to get a high back Model C2, and which one you want depends on whether you already own the chair. If you are buying new, the Model C2 High Back is a complete chair at $4,299 and there is nothing to fit. If you already have a standard Model C2 and your needs have changed, this part gets you there for $399 without replacing a working chair. It installs straight to the existing frame with no cane system, which is the detail that keeps it simple and cheap. What it gives you is a 20" back against the standard one, 7" more height, a back support height running 21.8" to 26.5", and four lateral pads for a deeper contour. It keeps the 90, 95 and 100 degree back support angles. It fits 18" and 20" seat widths, so a 16" Model C2 is out.
Straight talk
Is it right for you?
A good fit if you
- already own a Model C2 and now need more back support
- want support above the shoulder blades rather than a standard seatback
- need lateral contouring from adjuster pads
- have an 18" or 20" seat width
Look elsewhere if you
- have a 16" seat width, which this does not fit
- are buying a new chair anyway, in which case take the Model C2 High Back
- need a backrest specified by a seating clinic, which needs the cane backrest kit instead
