User Guidelines
The Stability Chair is a sophisticated piece of equipment that,
when used properly, can facilitate many Pilates exercises safely and
effectively. However, care and caution must be taken as there are
some inherent dangers when using any exercise equipment – especially
when spring resistance is involved.
For inexperienced or first-time users, the Stability Chair should
only be used under the supervision of a trained professional.
This manual includes general guidelines for setup, usage and safety.
To get the most out of your Stability Chair, Merrithew Health & Fitness
offers a full range of instructional DVDs and manuals. Personalized
training is offered through our Corporate Training Center and
LicensedTraining Centers.

Care & Cleaning
Wipe vinyl surfaces with a mixture of water and tea tree oil, a natural
disinfectant. Add 5 ml or 1 tsp of tea tree oil to a 1L or 1qt spray
bottle of water. A mixture of mild soap and water may be used to
remove more persistent dirt. Ensure cleaner does not leave an oily
residue, or make surfaces slippery. Clean all metal surface areas
as required, using a soft cloth and gentle cleaner.
If necessary, hinges can be cleaned with a cloth and window cleaner,
(spray cleaner onto the cloth first, not directly on the equipment).
It is not necessary to lubricate the hinges.
Mechanical
Safety Check
We recommend a monthly inspection
of the following elements:
Daily
wClean all surface areas after each use as per

Weekly
wCheck all springs for wear and damage and replace as needed
Monthly
wEnsure all nuts, bolts and screws are securely fastened
Every Two Years
wReplace all springs
FAILURE TO PERFORM RECOMMENDED SAFETY CHECKS, OR
USING THE MACHINE WITH IMPROPERLY ADJUSTED, BROKEN
OR WORN PARTS, COULD RESULT IN SERIOUS BODILY INJURY.
CAUTION
IMPROPER USE OF EXERCISE EQUIPMENT MAYCAUSE
SERIOUS BODILY INJURY. TO REDUCE RISK, PLEASE READ THE

Safety & Usage
Full instructions on proper set-up and execution of each exercise
is provided in the STOTT PILATES®Complete Stability Chair Manual.
Thefollowing are general guidelines only.
FOR SAFETY REASONS: DO NOT LIFT CHAIR FROM CHAIRSEAT,
GRIP METAL FRAME INSTEAD.
wBe careful that skin does not get caught when attaching and
detaching springs.
wEnsure springs are securely hooked on the eyehooks.
IF A SPRING IS NOT SECURE, IT MAY UNHOOK AND DETACH
WITHHIGH FORCE.
wWhen changing springs, always leave one spring on while moving
the desired spring into place to ensure the pedal does not fall.
wCare must be taken when seated or standing on the Stability
Chair, ensuring there is sufficient surface area available to maintain
balance during the exercise.
wIn exercises where weight is displaced away from the Stability Chair
(e.g. Spring Eagle), a trained professional must sit on the Chair to
provide counterbalance.
NEVER STRETCH OFF THE SIDE OF THE CHAIR OR SWING FROM
THE HANDLES AS THIS MAY CAUSE IT TO TIP.
wBe careful to not place fingers or toes underneath the pedal
or on top of the metal base of the Stability Chair.
wTake care when attempting any new exercises, as the pedal may
propel the exerciser forward or leave them in a precarious position
without sufficient support.
wWhen hands or feet are on the pedal, ensure they are secure and
will not slip. IF THE PEDAL IS RELEASED SUDDENLY, THE FORCE OF
THE SPRINGS MAY CAUSE INJURY, OR THE EXERCISER MAY LOSE
BALANCE AND FALL.
wGripper Mats may be used to prevent slipping.
wProper fitness apparel (including sticky socks) is recommended
whileusing this equipment.
wBe careful to keep fingers, toes, clothing and hair away from the
space between the two pedals on the Split-Pedal Chair.
SPRINGS
Four springs in two tensions and three spring tension locations make
the Split-Pedal Stability Chair highly versatile and easily adjustable to
accommodate each user’s abilities and strengths.
wWhen attaching springs, hook them to the pedal first, then
to the vertical frame. During regular use, change springs
by unhooking them from the vertical frame only.
wSprings should remain attached to the pedal at all times.
wAlways attach the heavy springs to the inner eyehooks and light
springs to the outer eyehooks.
wWhen changing springs, always leave one spring on while moving
the desired spring into place to ensure the pedal does not fall.
wDo not have any weight on the pedal(s) when changing springs.
SPLIT-PEDALS
The Split-Pedal Chair has two pedals that can move independently or,
locked together, form one pedal. Splitting the pedals allows you to
work bilaterally, unilaterally and reciprocally to rebalance muscle and
challenge core stability.
wTo join pedals: loosen both star knobs and rotate lock,
ensuring it completely hooks onto metal shaft of star knob.Tighten
both star knobs.
wTo split pedals: loosen both star knobs and lift open side
of lock from shaft or star knob and rotate so it is completely under
one pedal.
wWhen splitting pedals, make sure a spring is attached on both
sides, as pedal will fall if unsupported.
MOVING THE STABILITY CHAIR
Grasp the handles and tilt the side with the wheels towards you.
HANDLES (for models with handles)
Handles provide support in some standing and sitting exercises.
They are easily inserted and lock securely into place. Handles can be
purchased separately and installed later by the user.
wTo insert or adjust handles: Loosen 3-prong star knob.
Pull pop-up pin and insert chair handle into chair handle receptacle.
Ensure bolt head faces away from the seat vinyl. Release pop-up
pin at desired height and tighten 3-prong star knob to secure
handle in receptacle.
wWhen performing exercises with the handles, ensure pop-up pins
are securely inserted into handles and both star knobs have been
fully tightened.
wNOTE: Do not tighten pop-up pins.
Pedals lock together for use as a single pedal.
