(including DEEP,
CONTOUR and LTS) back supports require the use of
four spacers to connect the back support shell to the
hardware shell bracket. 1.5” of seat depth is used.
ACTA-RELIEF™ requires the use of at least a 1” spacer to connect the back support shell
and shell bracket. 2” of seat depth is used in this conguration which is standard when
shipped with a back support. This allows for the user to still immerse through the shell of
the Acta-Relief™ back support effectively reducing the amount of seat depth used from
that listed.
Extra spacers may be used to increase the available immersion. The possible shell spacer
congurations include 1” spacers only, 2” spacers only, or 1” and 2” spacers combined.
When using a head support with Acta-Relief™, an extra track spacer may be needed for
clearance. This spacer requires an additional .356” of seat depth.
See page 14 when
using shell spacers.

SEAT DEPTH USED = the distance from the base mounting plate to the rear face of the back support shell. This is the distance required for the Compass
