Gaming chair Onex STC Tribute Hardcore Black — ergonomic PC/console seat, adjustable height and recline

The Onex STC Tribute Hardcore Black gaming chair is an ergonomic PC and console seat engineered for extended sitting sessions. It combines a contoured backrest, adjustable height mechanism and a reclining function to provide consistent support during gaming or focused work. The design integrates targeted lumbar support and armrest accommodation to help maintain a neutral posture and reduce strain over time.

Advantages

The chair’s ergonomic profile and adjustable features allow personalization of seating position for different users and activities. Its reclining mechanism enables changes in torso angle to relieve pressure on the lower back, while the height adjustment aligns the hips and knees for better ergonomics. Designed for stability, the seat construction supports dynamic movement without sacrificing posture support.

Suitable for

• PC and console gaming sessions
• Home office and remote work
• Streamers and content creators who spend long periods seated
• Casual multiplayer or competitive play requiring reliable support

Key specifications

• Ergonomic contoured backrest with targeted lumbar support
• Adjustable seat height via gas-lift mechanism
• Reclining backrest with multiple angle positions
• Padded armrest accommodation for forearm support
• Durable upholstery and reinforced frame for daily use
• Stable base with smooth-rolling casters suitable for hard and soft floors

How to use

Adjust the seat height so that your feet rest flat on the floor and your knees form approximately a right angle. Set the backrest recline to a comfortable angle that maintains contact with the lumbar area; small changes in recline can reduce pressure on the spine during long sessions. Position the armrests to support your forearms close to keyboard and controller height to minimise shoulder elevation. Use the chair’s swivel and casters to reposition without twisting your torso.

Usage recommendations

For prolonged use, alternate between upright and slightly reclined positions every 30–60 minutes, and take short standing or stretching breaks to maintain circulation and reduce muscular fatigue.
