Overview
Bouncyband's weighted balance ball chair, a 25.5 inch stability ball with a flat weighted base so it stays put at a desk or classroom chair instead of rolling away.
The weighted bottom is what sets this apart from a standard exercise ball, it's built as active seating rather than a workout accessory. Bouncyband markets it toward focus and fidgeting, particularly for kids, alongside general posture and core benefits.
- 25.5 inch weighted, no roll design
- Rated for users over 5'6 tall
- 400 lb max weight capacity
- Includes pump, 2 stoppers, tape and stopper remover
Who it's for
Works for adults over 5'6 wanting fidget friendly desk seating, and for parents whose kids need movement to concentrate during schoolwork. Less suited to shorter adults or anyone needing the seat to sit level with a standard desk, some reviewers found even the largest size sat too low.
What buyers say
From Amazon customer reviews.
Several buyers, including parents of kids with ADHD doing virtual school, say the constant small movement helped concentration noticeably. Complaints center on the included pump being slow or breaking before finishing inflation, and a few reviewers found the seat height too low for their desk even at the larger size.
Strengths and trade-offs
Drawn from this product's published specifications.
- Weighted base prevents rolling when unattended
- Reported to help kids and adults with focus and fidgeting
- Comes with pump, stoppers and measuring tape
- Included air pump reported as slow or prone to breaking
- May sit too low for some desk heights even at max size
- Best suited to a specific height range, over 5'6
Performance notes
The weighted base is what keeps this from behaving like a typical exercise ball, staying in place when you stand up rather than rolling off. Reviewers who are shorter or have low desks found the seat height sat lower than expected even at the largest size, so fit depends on user height and desk height together.
