A separate cover for the R82 x:panda back rest extension. Back rest extensions add height above the standard back to support a taller trunk or a head control setup, and this is the replacement cover for that section.
Covers on the upper back take a lot of contact from the head and neck, so they soil and wear faster than the rest of the chair. Ordering the extension cover on its own means you can freshen that section without replacing the extension or taking the chair apart.
It is also worth having a spare where a client drools or is fed in the chair, so the seating is never off the road waiting on a wash.
