School Chair (SC-100/200/300) Instructions
TherAdapt®School Chair (SC-100/200/300) Instructions: Page 2 of 5
Packing List:
(1) Basic chair with slip-resistant seat (flat or angled) and vinyl back
(1) 1” wide pelvic strap with (1) side release buckle and (2) double slotted rings
(2) Knobs with ¼ - 20 stem bolts
(4) Leg height adjustment pieces with (1) ¼ - 20 T-nut each / (4) total
(4) 1 ¾” ¼ -20 Allen head bolts
(8) 1 ¾” ¼ -20 hex head bolts
(8) Thru-knobs with ¼ -20 inserts
(10) Nylon washers
(1) Metal seat support bracket (SC-300)
The basic School Chair comes pre-assembled but it should be adjusted properly to the individual
user to provide a customized fit. To adjust the chair the following steps should be followed:
1. Adjust the seat height. Remove the bolt-knob
assembly from the front and back legs, select the height
desired, and re-insert the bolts. Tighten the knobs
securely. Note: Use the same-paired holes on both the
front and back legs.
2. Adjust the seat angle. The School Chair comes
standard in a flat-seat position. To switch the seat to a
7° angle position remove the (2) ¼-20 Stove bolts at the
back of the seat/side rail assembly and lightly loosen
the (2) ¼-20 Stove bolts at the front of the seat/side rail
assembly. Lift up the back of the seat and align the seat
with the upper pre-drilled holes and reinsert the bolts.
Tighten all (4) ¼-20 Stove bolts securely. Note: Arms
must be removed first.
3. Adjust the seat depth. Loosen the two knobs with
stem bolts under the seat. Adjust seat depth so as to
leave 2” – 3” of space behind the bend at the knee and
the front edge of the chair, when the hips are all the
way back in the chair.
4. Adjust the pelvic positioning belt. The 1” adjustable pelvic belt with side release buckle should be
positioned in the notch created by the bend of the lap between the thigh and the pelvis, and tightened
snugly. Note that the double slotted rings on each side of pelvic strap have the loose ends of the straps
threaded back through. This prevents the strap from slipping, makes the belt completely adjustable and
allows the belt to snap closed at any location
