Universal gaming chair COUGAR Defensor S Jet Gray F — upholstered seat, 760×690×1295 mm, 150 kg max

The COUGAR Defensor S Jet Gray F is a universal gaming chair with an upholstered seat designed for desktop gaming and extended use. The chair measures 760×690×1295 mm and supports users up to 150 kg. It combines an adjustable lumbar system, memory foam neck support, high-density molding foam, and a deeper, wider seat to provide stable ergonomic support during long sessions. Upholstered in a leather-like breathable fabric, the Defensor S balances wear resistance with a natural touch and includes features such as a back pocket, 4D folding armrests with removable velvet sleeves, a Class 4 gas lift and a steel alloy 5-star base with extra-size wheels for reliable stability and mobility.

Advantages

The integrated PushBack advanced lumbar support allows precise control of pressure on the lower back to help maintain the natural lumbar curve, reducing strain during prolonged sitting. Magnetic memory foam neck pillow conforms to the neck for targeted pressure relief while high-density molding foam contours to the body for long-lasting comfort. The 4D folding armrests can be positioned for optimal arm support or folded back to allow full freedom of movement. The leather-like upholstery improves breathability and wear resistance compared with conventional synthetic covers, and the deeper, wider seat improves weight distribution and sitting stability.

How to use

Set the chair on a flat surface and adjust seat height with the piston lift so your feet rest comfortably on the floor and knees form approximately a 90° angle. Use the PushBack lumbar control to set the amount of lumbar pressure that maintains your natural lower-back curve, and position the magnetic memory foam neck pillow at a height that supports your cervical spine without pushing the head forward. Adjust the 4D armrests for height, depth, width and rotation to align forearms with your desk or fold them back when you need unobstructed arm movement. Use the recline lever to change the back angle between 90° and 155° and set tilt tension to control rocking resistance; lock the back when you find a comfortable position.

Usage recommendations

For long gaming or work sessions, alternate sitting positions periodically, adjust lumbar support and neck pillow to avoid prolonged static posture, and use the deeper seat to distribute weight evenly. Ensure the gas lift and base components are checked and tightened during routine maintenance and avoid exceeding the stated maximum user weight.
