GRAVITY CHAIR

Medifab recommends that a clinician such as an Occupational Therapist be consulted to
determine if the Gravity Chair is appropriate for the user. To avoid injury, read, understand
and follow all instructions and warnings in this manual before installing and using the
Gravity Chair, particularly the Safety Precautions. Please note colours are subject to
change.

Introduction

What makes Gravity Special?

SUPPORTING THE ARMS in a position

with elbows forward, so shoulders are at
a natural, relaxed position, means high
muscle tension is milder

Narrow shape

SUPPORTS THE
BODY in a good

position

The angle of the knee is

LESS THAN 90°

POSTERIOR/ANTERIOR
TILT can be adjusted by

the tilt wedge

1. Head Support: Ergonomical wave-shaped foam keeps the head position stable and
prevents the head from falling sideways

2. Cover: Classic version has air-breathable fabric on user contact surfaces and
rear back panel, with wipe-down in all other areas. Wipe-Down version is fully
wipe-down, including internal contact surfaces where client is seated

3. Seat Liner: Air mesh fabric with quilted cushion inside keeps the back dry and
comfortable

4. Spacer: Located beneath the cover under the hips. Can be removed to make
sitting position deeper if necessary

5. Side Pocket: Store this user manual and other small belongings inside

6. Tilt Wedge: Use to recline the chair to the most appropriate position for the user

Reclined seat and back mean
that both sides of the chair keep
the user’s POSTURE STABLE
without the use of belts and pads

INSTALLATION & USER MANUAL

Supportive Seating: Recline of the main body keeps the user in a stable position, and as the seat and back are always at
right angles, the user’s hips take the weight.

Soft: Because there are no hard parts at all, there is no pain in the body areas, which have contact with the chair.

Stable: Though the Gravity Chair is soft, it guarantees a stable seating position because it distributes pressure and

movements, and the trunk is supported according to the body form.

Ability to absorb movement: Sudden movements caused by muscle tension or extensive stretching are absorbed, because
the seating unit follows the movement by deformation. After the deformation it turns slowly and automatically to its original
position.

Lateral support: In spite of an insucient positioning control of the patient he/she will get into a good seating position due
to the adjusting form of the chair. The narrow design of the chair leads the sitting person nearly always to a symmetrical
position, especially, when the muscles are relaxed.

Easy adjustment: The Gravity Chair can be adjusted easily for patients with deformities and contractions by grinding away
the foam.

Lightweight: The Gravity chair is light and easy to move around.

A great way to sit: If a client is always lying down during the day, step by step the times in a lying position can be reduced

and the problems of permanent lying can be avoided when introducing the Gravity chair.

The aim is relaxation: Using the Gravity Chair as an
alternative seating system makes life not so monotonous
and the disadvantages of a permanent position are
avoided.

This positive feeling becomes even more intensive,
when the position inside or outside the Gravity Chair
is often changed. Relaxing increases the possibility to
communicate and makes it easier for the patient to have
a good relation to his/her environment.

Four sizes for children to adults: Choose the size using
the seat depth, which should be approximately 2 cm
shorter than the length of the upper leg of the client. If
the seat width is too small, it’s easy to grind in the foam if
necessary. If the seat width is too big, just use an additional
cushion beside the user.

Upholstery cover care: The cover is comfortable and soft.
It is made of 100% cotton and can be removed from the
chair and washed in the washing machine. The specific
material of the seating cushion infill absorbs sweat etc,
and this can be washed also.

Gravity Chair Characteristics

GRAVITY CHAIR

Reclining is the most important factor of a Gravity Chair to keep optimum sitting position.
The tilt wedge is easy to adjust and use to control the seating position. Recline the chair
until the head and upper body become stable.

WARNING

Pay attention to those who have tonus and reflex movements. Special caregiver
attention is required to prevent user slipping.

Posterior Tilt

Anterior Tilt

If the user has an insucient postural balance to the left or right, tilt can be adjusted
using the tilt wedge.

WARNING

Use caution to ensure that chair is in a stable position.
Tilt wedge cannot be used in conjunction with the mobile base.

INSTALLATION & USER MANUAL

Safety Precautions

A Gravity Chair can be referred to as the user’s “second chair” to relax in - if the “primary
chair” is used for dining, playing and studying. It is recommended that you alternate
sitting patterns between the Gravity Chair and the users “primary chair”.

WARNING

More than 30 minutes in the same position may cause the user pain. It is
recommended to change sitting position regularly and/or get out of the chair every
30 minutes. For users who have diculty changing their position themselves, special
attention by the caregiver is needed.

WARNING

Never use the Gravity Chair close to fire, cigarettes, lighters or heaters.

WARNING

During usage, do not leave the user unsupervised. The user could lose balance which
could cause dangerous situations.

WARNING

Do not use the Gravity Chair for other purposes than the original intent. Do not use
it as a Car Seat. Do not play with it nor use it as a step stool. This may cause harm.

Maintenance and Cleaning

Use mild detergent to wipe o dirty covers and seat pad, or dry in the shade after washing
with water. Seatpad is made from 100% polyester and Cover (main body/tilt wedge/
headrest/pocket) is made from 100% cotton.

WARNING

Pay special attention when you close the Gravity Chair Zipper.
Do not force the zipper, to bit the edge of the inside urethane
foam as this results in sticking and/or derailed zipper in the
worst case (see Figure 1a).
When closing the zipper, pay utmost attention and zip it up very slowly and carefully

pushing urethane foam edge inward wby fingers in order for the zipper not to bit the
foam edge. Take special attention at the corners (see Figure 1b).
