Active sitting for home and office
A chair that works your core while you work
The Flexi Muscles balance ball chair swaps a static seat for active sitting, so your posture and core get stronger every time you sit down.
Shop the chairWhy a balance ball chair
Sitting still all day is the problem, not the chair
A normal office chair holds you in one fixed position for hours, which is exactly why your back stiffens up and your posture slips by 3pm. The Flexi Muscles balance ball chair fixes that by design: the ball underneath you means your body is always making small adjustments to stay balanced, which keeps your core switched on and your spine in a better position, without you having to think about it. You still get a backrest and wheels for normal desk use. The difference is what happens while you sit.
Engages your core
Active sitting encourages your body to make subtle adjustments while seated. Those small movements engage your stabilising muscles all day, without a dedicated workout.
Improves your posture
The active sitting design encourages proper spinal alignment and helps reduce slouching, by engaging the muscles that support good posture.
Comfortable for long days
The combination of the balance ball, ergonomic backrest and supportive frame is built to stay comfortable through extended periods at your desk.
The ball comes off too
Unclip it from the frame and use it on its own for stretching, balance work or core exercises. One product, two uses.
Rolls where you need it
Smooth-rolling wheels let you move it around your workspace or between rooms, just like a normal office chair.

Who it's for
One chair, wherever you need to sit better
Active sitting works the same way wherever you use it: small, constant adjustments that keep your core engaged and your posture honest, instead of letting you sink into a fixed position for hours. Suitable for office workers, remote workers, students and fitness enthusiasts, anyone looking for a more active and engaging seating option.
Home office and study
Specifically suited to desks, workstations, study areas and home offices, so it slots straight into your existing setup. If you spend hours at a laptop, the constant small balancing keeps your core working and your back straighter, without changing how you work.
Workplace and classroom
Wheels make it easy to move between desks, and it holds up to daily use across home offices, classrooms and coworking spaces. In shared spaces and long office or school days, that durability and mobility matter just as much as the active sitting benefit itself.
Standalone exercise
Detach the ball whenever you want a dedicated stretching, balance or core session, then clip it straight back into the frame. One purchase covers your desk chair and a piece of home exercise equipment, rated to 150kg so it holds up to real training.
