KAB K4 Premium All Fabric 24 Hour Office Chair
The KAB K4 Premium is engineered for 24-hour continuous use in demanding environments including control rooms, operation centres, and general office settings. Rated to 31 stone (200kg), this heavy-duty office chair combines robust construction with comprehensive ergonomic adjustments to support operators of all heights during extended shifts.
Heavy Duty Construction for 24/7 Use
Built on a robust steel frame with a 30 stone rated gas lift, the K4 Premium is certified for 24-hour use. The 5-star base provides stability for users up to 31 stone, whilst castors suitable for hard floors ensure smooth mobility. Optional rubber soft tyre castors and polished aluminium base upgrades are available on request.
Comprehensive Ergonomic Adjustments
The K4 Premium features an adjustable seat base cushion with 50mm length adjustment (430-480mm) to accommodate different leg lengths. The seat cushion tilt adjuster offers 0 to 7.5 degrees upward tilt, whilst the adjustable backrest recline allows you to find your optimal working position. Air lumbar support provides customisable lower back support, and the height-adjustable, tilt-adjustable headrest reduces neck strain during long shifts.
KAB Tilt System Technology
Side-mounted rotary controls make adjustments intuitive without reaching underneath the seat. The system accommodates users weighing 50-200kg with easy weight adjustment and tension range settings. The 100mm gas-assisted height adjustment features an anti-kick safety system, whilst seat tilt with tension adjuster allows fine-tuning of recline resistance.
All Fabric Comfort
The all-fabric version features contoured cushions designed for all-day comfort. Tip-up comfort armrests provide flexibility when entering or exiting the chair. The modern ergonomic styling of the K-Series ensures the chair suits professional environments whilst delivering the functionality required for intensive use.
Customisation Options
Further options available on request include low or high gas lift alternatives to the standard medium lift, footring attachment, rubber soft tyre castors, and polished aluminium 5-star base. Standard seat height with medium gas lift ranges from 460-560mm, with low (440-510mm) and high (530-650mm) options available.

Frequently asked questions
What distinguishes the KAB K4 Premium from other 24-hour chairs?
The KAB K4 Premium is specifically designed for multi-user environments where different operators need to adjust the seat depth. It features a unique adjustable seat base cushion that can be extended by 50mm and tilted upwards by up to 7.5 degrees. This ensures that users of varying heights can maintain correct circulation and thigh support during 24-hour shifts.
How does the air lumbar support system work?
Unlike standard mechanical lumbar supports, the K4 Premium utilises an air lumbar system. This allows the user to precisely inflate or deflate the lumbar cushion using a hand pump, providing a bespoke level of pressure that contours exactly to the lower back. This is highly effective for reducing fatigue during long-duration sitting.
What is the maximum weight capacity of the K4 Premium?
The K4 Premium is built on a heavy-duty steel frame and is rated for users up to 200kg, or approximately 31 stone. This makes it one of the most robust ergonomic chairs available, supported by a 30-stone rated gas lift and a wide 700mm 5-star base for maximum stability.
Is the fabric version of the K4 Premium suitable for intensive environments?
Yes, the fabric upholstery used on the K4 Premium is selected for its high Martindale rub count and durability. Fabric is often the preferred choice in 24/7 control rooms because it offers better breathability and thermal comfort, preventing the user from feeling too hot during long shifts.
How do I clean the fabric on a 24-hour K4 chair?
The high-performance fabric can be maintained with regular vacuuming to remove dust and debris. For spots or spills, a damp cloth with mild upholstery cleaner is usually sufficient. Because it is designed for intensive use, the fabric is resistant to pilling and thinning over time.
Which KAB K4 Premium model is right for me?
The choice between fabric and leather depends primarily on your working environment. The KAB K4 Premium All Fabric is the best option for users who prioritise breathability and a softer, more cushioned feel. The KAB K4 Premium Leather is recommended for shared 24/7 environments like emergency services or control rooms, where easy cleaning and a prestigious executive appearance are the main requirements.
