1. Ergonomic Design & Lumbar Support
High Backrest: Designed to support the entire spine, including the cervical region.
Integrated Lumbar Support: Often features a built-in, adjustable lumbar support system (like a dial or knob on the side) that allows you to precisely control the protrusion of the lumbar cushion to fit the curve of your lower back. This is a key upgrade over removable pillows.
4D Adjustable Armrests: The armrests can be adjusted in four ways:
Up/Down (Height)
Forward/Backward
Left/Right (Angle)
In/Out (Width)
2. Premium Materials & Build Quality
PU Leather Upholstery: The primary material is high-quality polyurethane (PU) leather, which is durable, easy to clean, and gives a premium look. The White & Black colorway typically features a white base with black accents on the back and sides.
Cold-Cured Foam Padding: Uses high-density, mould-breaking foam that is more resilient than standard foam. It's designed to provide comfort without bottoming out, and it retains its shape much longer, preventing sagging over time.
Metal Frame: The internal structure is typically a sturdy metal frame, providing stability and longevity.
Aluminum Base: The chair sits on a strong, lightweight five-point aluminum base (not nylon), which is more premium and durable.
3. Adjustability & Functionality
Multi-Function Tilt Mechanism: This is the core control unit under the seat. It usually allows for:
Reclining: Ability to lock the backrest at any angle between 90° and 180° (fully flat).
Rocking / Tilt Function: Unlock the mechanism to rock back and forth.
Tilt Tension Control: A knob to adjust the resistance of the rocking motion.
Class 4 Hydraulic Gas Lift: Provides smooth and reliable height adjustment. A Class 4 cylinder is rated for heavier use and is a mark of a quality chair.
High-Nylon Casters: The wheels are typically 60mm-65mm silent, smooth-rolling casters designed for both hard floors and carpets, preventing scratching and reducing noise.
4. Comfort & Additional Features
Headrest Pillow: Includes a memory foam head pillow that is often adjustable up and down to properly support your neck. It is usually attached with straps or magnets.
Lumbar Pillow: While it has integrated lumbar support, it often also includes an additional memory foam lumbar pillow for extra, customizable comfort.
Ergonomic Design: The chair's shape, with its winged sides and bolstered seat, is designed to hug your body for support and stability during intense gameplay.
