The Kore wobble chair, sized for every age
Kore Design makes one type of chair across more sizes than any other active sitting brand we carry. The wobble chair, with a patented rounded base that lets the seat rock in any direction while you sit. Sized for ages three through adult, with adjustable models that grow with kids across multiple school years.
The brand is the one teachers, parents, and ergonomic specialists reach for when active sitting needs to fit a child or a classroom alongside an office.
What a wobble chair does
The patented rounded base lets the chair rock and shift in any direction while you sit. Your body responds with small constant movement that engages your core, supports your posture, and keeps your lower back from settling into the slumped position a static chair lets you fall into.
For kids who fidget, the chair gives them a way to channel that energy without leaving their seat. For adults at a desk, it adds movement back into a day that mostly involves sitting still.
The full Kore size range
Kore covers a wider age and height range than any other wobble chair brand we carry.
- Pre-school sizes start at a 12-inch seat height for kids aged three to five.
- Elementary and middle school sizes climb through 14, 16, and 18.7 inches.
- Adjustable models in the middle of the range grow with kids across multiple school years.
- Teen and adult sizes adjust from 18 inches up to 31.5 inches, with the largest model reaching standing desk height and supporting up to 350 pounds.
Matching seat height to user is the most important Kore decision. Feet flat on the floor, knees at roughly hip level.
Why Kore is so widely used in schools
Kore wobble chairs are listed by the manufacturer as proven options for students with ADD, ADHD, and autism. The constant micro-movement gives kids a way to release energy without disrupting the room, which usually translates into better focus during seated work.
That's why active sitting from Kore shows up in IEP and 504 plans, in general classrooms looking to support restless students, and in special education programs across pre-school through high school. The full classroom selection sits in Classroom Active Sitting.
