Improve neuromuscular coordination

Ideal for actively aging individuals who want to improve or maintain functionality, as well as athletes looking to take their performance and agility to the next level. Balance training improves the communication between the brain and the muscles.

Reduce back ache and improve posture with dynamic sitting

Back pain is often the result of having weak stabilizing muscles supporting your joints. Without muscular support, your joints simply collapse. The Stability Cushion is effective in rehabilitating your back because it strengthens and develops the core muscles that help to stabilize the spine. Through dynamic sitting, challenge your core to support the spine and maintain balance on the cushion.

Add dynamic challenge to your workouts

The Stability Cushion adds challenge to your workouts by providing a plane of instability that forces joints and muscles to react to maintain your balance. Enhance your stability, strength and balance while performing exercises in standing, sitting, kneeling or laying down on your back or stomach.

Use in rehab and physical therapy of knee and ankles

The Stability Cushion can be effectively used in post-rehab exercise, ideal for those suffering from sprained ankles, arthritis, knee injuries, post-knee surgery, following joint replacement surgery and collateral knee ligament injuries.

Help kids stay focused

Occupational therapists, teachers and parents of special needs children have found that Stability Cushions help children with sensory needs stay focused. The small muscle adjustments needed to balance help kids develop core strength while the movement stimulates the brain enough to create focus in the classroom.

Highly recommend this product!

By , ON, CA on February 22, 2018

I am a registered physical therapist and recently purchased an this product for my husband who has been experiencing significant back pain when driving in his car. The cushion has been fabulous and now enables him to drive in comfort. It seemed that no matter what he previously did with adjustable car seat....he would get crippling leg pains. He also uses it when he sits on kitchen chairs - where it works to ensure ‘active sitting’. Highly recommend the cushion for those individuals who can’t seem to get comfortable in their seats!

Sanity saver - helps me stay focused to complete work

By , ON, CA on March 06, 2017

Have been using this cushion for three years - gave mine to my elder parent to ease their discomfort and realize i cant live without one! it has helped my elder father immensely with the normal discomfort of sitting or being in bed more than one would want! helps with comfort, and especially with settling the fidgets that set in when trying to complete something boring but which requires focus and stamina! thank goodness!!!
