Frequently asked questions
What makes the KAB Executive chair different from standard office chairs?
The KAB Executive is a heavy-duty, 24-hour certified chair specifically designed for managers and executives in intensive environments. While standard chairs often have a weight limit of 110kg, the KAB Executive is built with a reinforced steel frame and a gas lift rated for 200kg (31 stone). It features wider, flatter cushions to accommodate larger body types comfortably over long shifts.
How does the KAB Tilt System help with fatigue?
The proprietary KAB Tilt System encourages "active sitting." It allows the chair to rock or tilt back safely, which helps redistribute body weight and reduce spinal compression. You can easily adjust the tension via side-mounted rotary controls to match your specific body weight (from 50kg to 200kg), ensuring the chair supports you perfectly without feeling too stiff or too loose.
Is the KAB Executive chair built in the UK?
Yes. Every KAB Executive chair is hand-built to order in the UK. This ensures a high level of craftsmanship and allows for specialised configurations, such as different gas lift heights or specific castor types for different flooring.
What is the difference between the KAB Executive and the KAB ACS Executive?
The KAB ACS Executive (Air Comfort System) features an advanced air-cell system in the backrest and seat. This allows the user to electronically or manually adjust the firmness of different zones of the chair. This is the ultimate choice for users who require highly specific pressure relief or those who find standard foam cushions too firm for long-term sitting.
Which KAB Executive model is right for me?
The choice depends on your specific comfort requirements. The standard KAB Executive is the industry benchmark for heavy-duty 24/7 use, offering robust mechanical support for users up to 31 stone. Choose the KAB ACS Executive if you require a more bespoke sitting experience, as the air-cell technology allows you to fine-tune the seat and backrest firmness to your exact preference.
