Sit actively with an adjustable kneeling chair with back support

Most office chairs keep you sitting in one passive position for hours. The Kneelix Flex Chair gives you another way to work.

Designed as a smarter second chair, it helps you switch into a more upright and active sitting position during focused work blocks. The angled seat encourages posture variation, while the dual knee pads help guide your position and the mesh backrest adds extra reassurance when you want support.

The Flex Chair is ideal for home workers, students and desk-based professionals who want more adjustability than a basic kneeling chair, without moving to a bulky office chair.

It is a practical tool for changing the way you sit throughout the day.

A second chair for better workdays

Stop sitting in one position all day.

Most office chairs are built for comfort, but comfort can quickly turn into passivity. After a few hours, your shoulders round, your hips close, and your body stays locked in the same position.

The Kneelix Flex Chair gives you another way to work.

Designed as a smarter second chair, it helps you switch into a more active sitting position during focused work blocks. Use it for deep work, writing, admin or study sessions — then alternate back to your regular office chair when your body needs a change.

One chair all day is the old way. Kneelix helps you switch the way you sit.

Adjustable support, without the bulk

Designed to support active sitting — not replace it.

The Kneelix Flex Chair combines the posture variation of a kneeling chair with the reassurance of added support.

The angled seat helps encourage a more upright working position, while the dual cushioned knee pads guide your posture without carrying all your body weight. The breathable mesh backrest adds light support when you need it, without turning the chair into a bulky office chair.

With adjustable seat angle, lockable castors and a compact metal frame, Flex gives you more control over how you sit — while keeping your workspace clean, practical and easy to move around.

Build your active sitting routine

Start small. Switch often. Work better.

Kneelix works best when it becomes part of your daily routine.

Start with short sessions of 20–30 minutes, especially during focused tasks. As your body adapts, use it for longer work blocks and alternate with your regular chair throughout the day.

The goal is to stop relying on one static position for every hour of work.

Use Kneelix when you want to sit taller, feel more engaged and bring more movement into your workday.

Adjustable details for a more personalised sitting position

The Kneelix Flex Chair is built for users who want more control over how they sit.

The breathable mesh backrest adds light support without making the chair feel bulky, while the adjustable frame helps you fine-tune your sitting angle during focused work blocks. Every detail is designed to support posture variation, from the curved support structure to the cushioned seat and knee rests.

Use it when you want a more flexible active sitting setup than the Core model, with added reassurance and adjustability for your daily work routine.

More support. More control. A smarter way to switch position during your workday.
