Gravity Chair
A positioning system to provide postural and sensory support for a range of different individuals.
The Gravity Chair provides a stable, comfortable and supportive sitting environment, a great alternative for users who might otherwise spend time on the floor for relaxation. The chair also provides a snug and safe feeling for users who benefit from increased proprioception feedback to assist with management of sensory processing. The Gravity Chair provides a great base from which a range of different therapy activities can be performed.
The Gravity Chair’s appealing look and neutral colour wipe-down covers make it fit into the home or school environment just like all the other furniture.

Functional benefits
Supported Sitting
A comfortable and supportive alternative to time on the floor or sofa in asymmetrical postures, especially important for those that are unable to sit independently. The low centre of gravity and stable base provides a secure but relaxed seating position, giving care-givers peace of mind.
Scriptable Accessories for Tailored Support
Optional medial thigh support, tray table and foot support available for all sizes to ensure the user receives the support they need.
Postural Management
A great alternative seating solution designed for support during relaxation as part of an individual’s 24-hour postural care program. Protection of posture during this time can enhance a person’s wellbeing, independence and participation in everyday life. The relatively narrow back support allows for good lateral postural support, assisting with mid-line positioning whilst the seat base flares at the front to assist with good hip positioning.
Alternative Relaxing Chair
The Gravity Chair can be used as an alternative relaxing chair. Whilst providing comfort for the child, it also gives the care-giver peace-of-mind, knowing that their child is supported correctly.
Proprioceptive and Calming Benefits
Deep sided support and close body contact increases the proprioceptive feedback the body receives, which can be calming for those who are easily overwhelmed by sensory stimuli and help control responses to these stimuli. The snug fit is great for users with sensory and intellectual disabilities who benefit from this close body contract which helps with raising self awareness and providing a calm, safe space.
Lateral Control
The width is relatively ‘narrow’ allowing good lateral posture and control. This helps to ‘hold’ the user in a mid-line position. The raised position of the arm supports also help to 'bolster' the user laterally, facilitating free breathing to enable increased blood oxygen.
Absorbs Spasm Tension
For users who experience extensor spasms or posturing, the foam properties in the Gravity Chair gently absorb the tension generated by the body, then once the user relaxes, the resilience of the foam brings the user gently back to the original supported posture.
Breathable or Wipe Down Cover Options
A fully wipeable cover option is available to assist with hygiene and cleaning where needed. Where management of temperature and thermoregulation is needed, the breathable cover option exists for maximum ventilation behind the user.
In both cases, a comfortable and breathable liner is provided as standard to assist with thermoregulation and moisture management.
Light and Portable
Lightweight design provides ease of movement within any indoor environment for maximum practicality
Adjustable Tilt
The standard tilt wedge can be used to achieve a more reclined or upright sitting position depending on the user and their goals. The wedge can be changed easily throughout the day to suit the activity at hand.
Added Growth for Increased Use
Width and depth liners are available for all sizes, providing opportunity to provide growth in the gravity chair, or to reduce the depth of the seat for users who find this too deep or uncomfortable.
Wedge Accessory
The Gravity Chair comes standard with a foam wedge that can be placed underneath the chair to allow tilting of the chair, forwards, backwards, and even sideways. This provides a nice way to position and stabilise the user’s head and body such as those with Scoliosis or limited head control.

Archer’s Gravity Chair
Archer is not only grounded and calm when seated in his Gravity chair, he is accepting and able to concentrate so much more than in a normal seated position.
It has been a blessing during lockdown and home schooling.
We love seeing the change its continually making, thank you Medifab.

Jack’s Gravity Chair
Thank you for an amazingly comfortable chair for my little Jack to grow up in! I suspect we will be purchasing every size to come! It’s the only chair where he can just relax comfortably, so we are very grateful! Thank you!

Teagan’s Gravity Chair
The Gravity Chair has made a tremendous difference in improving the quality of life of our handicapped daughter, Teagan. It is by far the most comfortable chair she owns; it’s like a big, soft hug around her. Not only is she relaxed and happy in the chair, it is low to the ground, allowing her to interact and play with her younger brother. We credit the Gravity Chair with the fact that her brother now walks up to her, strokes her hair, and kisses her on her cheek. That is priceless.
Teagan’s Mum
The Gravity Chair has made such a positive impact in Teagan and her Family’s life! As a Physical Therapist, one of our main goals is to achieve optimal positioning, with the use of equipment, for the health of many body systems including respiratory, neurologic, musculoskeletal, cardiovascular, renal, immune and digestive systems. The Gravity Chair easily assures we are addressing these medical needs for Teagan. The Gravity Chair allows Teagan to be in a comfortable, upright and supportive position which not only helps her medically and physically, she is able to participate socially with her one year old brother, Simon, as well as have more access to her toys, people and sensory experiences to advance her cognitive and communication skills. The chair itself is designed to give head, lateral and pelvic support without the addition of bulky, obtrusive trunk laterals, chest harness, pelvic straps, etc.. as Amanda expressed “it’s like a big, soft hug around her”. It is also so nice to have only one safety belt for ease of transfers, a mobile base and incline when needed.
I really appreciate all that you have done for Teagan and her Family! Without sharing Teagan’s specific medical needs in the testimony, the Gravity Chair has been a “life saver” for her.

Special chairs work wonders!
At Hamilton North School, it’s not unusual for the special-needs students to become agitated, sometimes for the smallest of reasons. And thanks to a grant from the Mazda Foundation, teachers have a new tool to counter that agitation, helping children to become focused again. Teacher Daina Brown calls them gravity chairs, special sensory chairs made out of contoured layers of foam that give the upset child a squeeze, similar to a hug. Brown said just five minutes in the chair can make a world of difference. Brown said the chairs conform tightly around the body, and the tightness allows the pupils to relax.
“At morning circle times, it keeps students calm and focused, so that they can participate.”
She said the chair moulds to the student, and there is a wedge underneath that enables the chair to recline to provide a calming sensation.
“It’s all about the pressure, that’s what gets them to relax.”
The smallest change in these children’s routines can disrupt them for the rest of the day. Brown said something as small as taking a different route to school, arriving late, or a change in staff member can upset them. She said in one instance, a child who usually comes to school on the bus came in a car. By the time he arrived, he was crying hysterically. She popped him in the chair and after 10 minutes, he was settled.
“The mum was able to leave and the student was able to carry on with the rest of their day.”
Brown said the majority of her students are nonverbal, but it is obvious by their expressions and body language that they love the chairs. The school’s paediatric physiotherapist, Susie Nyika, said students with disorders such as Rett Syndrome, ASD or Fetal Alcohol Syndrome may bang their heads, rock or hide under tables, which is not only distressing for the child, but can disrupt the rest of the class.
“One of the biggest challenges when educating the children is their sensory systems being completely out of sync, affecting their ability to focus.”
Nyika said the chairs provide a sensory break, calming them. Hamilton North School received close to $4500 from the Mazda Foundation last month to purchase two chairs.

How the Gravity chair makes a difference in Mauri’s life
Mauri has a diagnosis of Quadriplegic Cerebral Palsy. For some time we have wanted to find a chair that would provide Mauri the support that he needs, while also allowing him to be relaxed and restrained as minimally as possible.
The Gravity Chair has been ideal for this. Due to its design, Mauri is able to be positioned safely in the chair with only a lap belt holding him. Mauri uses his Gravity Chair multiple times every day. He is able to be fed in it, both orally and tube fed.
It is ideal for interactive activities such as reading and games. It is also a comfortable relaxing place for him to watch his Wiggles DVD’s in.
I find the Gravity Chair to be very light and portable, and I really appreciate finding a product that is both simple and functional.
I would recommend the Gravity Chair to any parents and caregivers with children who have a disability.
Mauri’s Mum
Siera’s Gravity Chair
We would like to say a huge THANK YOU, to Wilson Home Trust for buying Siera’s gravity chair.
We appreciate it very much. Siera is very comfortable in it & even fell asleep in it today & is now watching tv in it.
It is very well made, soft yet supportive. Family & friends have commented on how awesome it is.
A thank you also to Claire at Mckenzie centre & Hayden at Medifab for helping make this available to us.
Anything we can do to make her day a little more comforty is well worth it.
Thank you once again, The Wilson Home Trust, you have given us a great start to the year.

Alex’s Gravity Chair
Alex is my very precious 6 year old son who has severe spastic quad/dystonic cerebral palsy. Over the past 6 years we have been inundated with a lot of supportive equipment inorder to meet all of his physical needs. Medifab’s Gravity Chair is one Alex’s latest pieces of equipment and to be honest I don’t think I can really call it equipment. We call it Alex’s ‘lazy chair’. It meets his physical needs perfectly but with 100% comfort. Allowing him to truly relax and look relaxed!
As a parent, I love not having to strap him down like I have to with so much of his other equipment. In his Gravity Chair he only has one lap belt which I pull his shirt down over it so he looks totally strap-free! For kids that are constantly strapped into equipment, this almost strapless feature is very important!
Alex spends a lot of his afternoons and evenings in his Gravity chair watching his DVD or having books read to him. He gets extremely tired with his morning schooling and therapy so he spends his afternoon relaxing. Alex got his Gravity Chair is an alternative for him wriggling about on the floor. Alex relaxes in a very bad posture when he is left to freely move on the floor so sitting up is just like cruising on the couch in a physio-friendly way! We have found him to have far less pressure spots in his Gravity chair than in any other equipment to which has been a big bonus. It has also been good during those long nights when he is unwell. He can be reclined to keep his airways safe whilst he sleeps on and off in comfort.
Another huge benefit we have found with the Gravity Chair is that friends and family can get nice and close to him when they visit without bulky hard chair parts getting in the way. It might not sound important but when your disabled child gets too big to sit safely on your knee, having hard metal between you and your child isn’t so nice. Lovely soft chair arms make it very easy to snuggle up!!
If you are looking for a chair for your child that promotes excellent posture and structural support and that also meets their need to relax and not be stuck down by strapping, then I highly recommend the gravity chair. My only regret is not getting one sooner!
