Overview
An inflatable PVC balance disc, 14 inches across and about 3 inches tall, that doubles as a wobble trainer for core work and as a seat cushion for posture. A hand pump ships with it so firmness is adjustable.
The dual textured surface gives you a choice of raised massaging bumps or a smoother side, and standing or kneeling on it forces small stabilizing corrections through the core and ankles. One buyer who tried it as a driving seat found it too narrow for a bucket seat, so treat the seating use as a supplement to exercise rather than a full replacement for a cushion built for that job.
- 14 inch diameter, 3 inch height PVC disc
- Hand pump included for inflation
- Raised bumps on one side, smoother texture on the other
- Weighs 2.2 lbs for easy transport
Who it's for
Fits people doing balance drills, seated core activation at a desk, light physical therapy, or even balance work with a dog. Adults hoping for a wide car seat cushion should look elsewhere; reviewers found this one too narrow for that.
What buyers say
From Amazon customer reviews.
Buyers used it for sensory and posture work with kids, balance training for dogs, and skating practice, and called the construction sturdy. One reviewer found it too narrow to use as a seat cushion in a bucket car seat, and another suspected their unit had a small pinhole leak near the pump valve.
Strengths and trade-offs
Drawn from this product's published specifications.
- Comes with its own hand pump
- Dual textured surface for different feedback
- Light enough at 2.2 lbs to travel with
- Works for both kids and adults
- Too narrow to use as a full driver's seat cushion for larger adults
- One buyer received a unit with a small puncture
Performance notes
The disc inflates with the included hand pump and can be set softer or firmer depending on how much air you add. Standing or sitting on the unstable surface recruits the core and lower body to hold balance, and the two textured sides give a choice between a firmer massaging grip and a smoother feel.

Questions about the ProsourceFit ps-2142-bd-grey
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How firm can the ProsourceFit Core Balance Disc be inflated?
It comes with a hand pump so you can add or release air to set the firmness anywhere from soft and wobbly to fully inflated.
Can adults use it as a seat cushion in a car?
One reviewer found it too narrow for a bucket driver's seat and ended up sitting over the sides, so it suits a wider chair better than a tight bucket seat.
Is the ProsourceFit disc suitable for kids?
Yes, reviewers used it with children, including for sensory input and seated focus activities, and found it held up well to daily use.
