Ergonomic Office Chair Thunder X3 TEGC-3073101.B1 — black/blue, adjustable height and recline

Thunder X3 TEGC-3073101.B1 — black/blue ergonomic office chair designed for extended sitting sessions in home offices, gaming setups and professional workspaces. The chair combines adjustable height and recline with padded seat and back to provide continuous lumbar and overall support. Built with a contoured backrest and supportive armrests, this model helps maintain posture while allowing personalized seating adjustments.

Advantages

The chair offers adjustable seat height and a reclining mechanism to adapt to different desk heights and body positions. Thick padded seat and backrest reduce pressure on hips and lower back during long periods of sitting. Contoured back and lumbar support promote a more neutral spine alignment. The armrests provide stable support for the forearms, reducing shoulder fatigue. Durable base and casters ensure stable movement and long-term use.

Suitable for

• Home office work and remote work setups
• Gaming sessions and streaming
• Long-duration desk tasks such as programming or content creation
• Study areas and student workstations
• Office environments requiring adjustable seating for multiple users

Key specifications

How to use

Adjust seat height so your feet rest flat on the floor and your knees form a roughly 90-degree angle. Use the recline control to set a comfortable backrest angle that supports the natural curve of your spine; lock the tilt when you find a stable position. Position the armrests so your forearms rest lightly while typing or using a controller, keeping shoulders relaxed. Regularly change posture and stand or stretch during long sessions to reduce muscle stiffness.

Usage recommendations

For optimal ergonomic benefit, pair the chair adjustments with correct desk and monitor height: top of the screen at or slightly below eye level and keyboard at elbow height. Inspect casters and base periodically and tighten fastenings as needed to maintain stability.
