Seat Depth

ACTA-Relief and ACTA-Relief LTS
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 Power Mount Hardware assembly, including spacers. Back support foam thickness varies by model and size and therefore is not
included in seat depth 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 configuration 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 configurations 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.
