Specifications

COUGAR's official specifications confirm the Navy Blue F variant as product number 3MDSFBUB.0001, with leather-like fabric, 4D folding armrests, 150kg weight support, and a 29.2kg product weight.

PushBack Advanced Lumbar Support

The defining ergonomic feature of the Defensor S is COUGAR's integrated PushBack Advanced Lumbar Support System.

Instead of relying on a loose lumbar pillow, the system is built directly into the chair and allows you to fine-tune how much pressure is applied to your lower back. COUGAR designed the system to help maintain the natural lumbar curve and provide adjustable support during extended sitting.

This makes it particularly useful when switching between upright productivity, competitive gaming, casual gaming, and relaxed sitting positions.

4D Folding Armrests

The Defensor S features COUGAR's advanced 4D folding armrests, originally developed for COUGAR's official VCT 2024 gaming chair and tested in an esports environment.

The armrests provide adjustable support when needed but can also be folded completely backward, clearing the sides of the chair when you want greater freedom of movement.

COUGAR also includes removable velvet fabric sleeves, providing a softer contact surface for your arms.

Leather-Like Fabric Surface

The Defensor S uses a distinctive leather-like fabric rather than conventional leatherette.

COUGAR describes this material as breathable and resistant to wear while retaining a smooth, supple, premium feel.

The Navy Blue F finish gives the chair a sophisticated appearance that works equally well in gaming rooms, streaming setups, home offices, and professional workspaces.

Wider & Deeper Seating

Compared with the original Defensor design, the Defensor S features a reengineered, deeper and wider seat.

The updated seat is designed to distribute weight more evenly while providing improved stability and ergonomic support across different sitting positions.

High-density molding foam provides the supportive cushioning underneath.

Magnetic Memory Foam Neck Pillow

A magnetic memory foam neck pillow is included for additional upper-body comfort.

The magnetic attachment allows you to reposition the pillow easily instead of relying on conventional straps, while the memory foam conforms to the user for comfortable neck support.

Recline Up to 155°

Switch between gaming, working, watching content, and relaxing with the Defensor S's adjustable backrest.

The chair can recline from an upright 90° position all the way to 155°.

You can also adjust the chair's tilt tension, allowing the body to rock within a small angle range with resistance adjusted according to your preference.

Heavy-Duty Class 4 Construction

The Defensor S is designed around a durable foundation.

Its TÜV-certified Class 4 gas lift provides smooth height adjustment, while the steel-alloy five-star base and extra-size wheels provide stability and mobility.

The chair supports users weighing up to 150kg / 330.7lb.
