Spending long hours in a gaming chair can take a toll on your body if you don't set it up correctly. The TC100 RELAXED Gaming Chair - Fabric Black/Black is designed for comfort, but to truly benefit from its ergonomic features, you need to adjust it to fit your unique body shape and sitting style. In this guide, we'll walk you through each adjustment point, ensuring you achieve perfect posture and maximize your comfort during those marathon gaming sessions or work-from-home days.

Proper chair adjustments not only prevent back and neck pain but also improve your focus and performance. Whether you're a competitive gamer or a casual user, understanding how to fine-tune your chair is essential. Let's dive into the step-by-step process of setting up your TC100 RELAXED for optimal ergonomics.
Why Posture Matters in Gaming
Poor posture while gaming can lead to a host of issues, including lower back pain, neck strain, and even long-term spinal problems. When you're immersed in a game, it's easy to slouch or lean forward, but these habits can cause muscle fatigue and discomfort over time. An ergonomic chair like the TC100 RELAXED is built to support your body, but only if you take the time to adjust it correctly.
Proper posture keeps your spine in a neutral position, with your ears, shoulders, and hips aligned. This reduces stress on your muscles and joints, allowing you to stay comfortable and focused for longer periods. By following the adjustment steps below, you'll create a seating setup that promotes health and enhances your gaming experience.
Step 1: Adjusting Seat Height
Start by adjusting the seat height. Sit in the chair with your feet flat on the floor and your knees at a 90-degree angle. Your thighs should be parallel to the ground, and you should be able to slide your fingers under your thighs with ease. Use the gas lift lever under the seat to raise or lower the chair until you find the perfect height.
If the chair is too high, your feet will dangle, increasing pressure on the backs of your thighs. If it's too low, your knees will be higher than your hips, which can compress your lower back. The TC100 RELAXED offers a wide range of height adjustments, so you can easily find the sweet spot for your height.
- Feet flat on the floor, knees at 90 degrees.
- Thighs parallel to the ground.
- Adjust using the gas lift lever under the seat.
Step 2: Setting the Backrest Angle
The backrest of the TC100 RELAXED can be reclined to suit your preferred sitting position. For most gaming and work tasks, a slight recline of about 100 to 110 degrees is recommended. This reduces pressure on your spine and helps you maintain a relaxed yet alert posture. Use the tilt mechanism on the side of the chair to adjust the angle, and make sure it locks securely in place.
If you like to lean back during breaks or while watching videos, you can recline further, but be mindful not to sit in a position that encourages slouching. The backrest's tension can also be adjusted to control how easily it reclines, allowing you to customize the resistance to your body weight.
- Aim for a 100-110 degree recline for active tasks.
- Lock the backrest securely to prevent unexpected movement.
- Adjust the tilt tension to match your body weight.
Step 3: Positioning the Armrests
The TC100 RELAXED features adjustable armrests that can be moved up, down, left, right, and angled. Position the armrests so that your arms rest comfortably with your shoulders relaxed and your elbows at a 90-degree angle. Your forearms should be parallel to the ground, and your wrists should be in a neutral position, not bent up or down.
If the armrests are too high, your shoulders will hunch, causing tension in your neck and upper back. If they're too low, you'll lean to the side, which can misalign your spine. Adjust the armrests to support your arms without lifting your shoulders, and make sure they are close enough to your body to provide support without forcing your elbows out.
- Elbows at 90 degrees, forearms parallel to the ground.
- Shoulders relaxed, not elevated.
- Adjust armrest height, width, and angle to fit your body.
Step 4: Fine-Tuning Lumbar Support
Lumbar support is crucial for maintaining the natural curve of your lower back. The TC100 RELAXED includes a built-in lumbar pillow that can be adjusted in height and depth. Position the pillow so that it fits snugly in the curve of your lower back, providing gentle support without pushing you forward.
If the pillow is too high or too low, it can cause discomfort and misalignment. You should feel the support when you sit back, but it shouldn't be so firm that it's uncomfortable. Experiment with the height and depth to find the setting that feels most natural and supportive.
- Position the pillow to support the natural curve of your lower back.
- Adjust height and depth for a snug but comfortable fit.
- You should feel support without pressure points.
Step 5: Adjusting Headrest and Neck Support
The TC100 RELAXED comes with a headrest pillow that can be adjusted to support your neck and head. When sitting upright, the headrest should rest at the base of your skull, not the top of your head. This helps reduce neck strain, especially during long sessions when you might be leaning back.
Adjust the headrest pillow's height and angle so that it gently cradles your neck. You should be able to rest your head back without tilting it up or down. If you find yourself constantly adjusting your neck, the headrest may need to be moved up or down.
- Headrest should support the base of your skull.
- Adjust height and angle for a neutral neck position.
- Avoid tilting your head up or down while sitting back.
Final Checks and Maintenance Tips
Once you've made all the adjustments, sit in the chair for a few minutes to ensure everything feels right. Check that your feet are flat on the floor, your knees are at 90 degrees, and your back is fully supported. Make small tweaks as needed until you feel comfortable and aligned.
To keep your TC100 RELAXED in top condition, periodically check that all adjustment mechanisms are tight and secure. Clean the fabric with a soft, damp cloth and avoid using harsh chemicals. Regular maintenance will ensure your chair remains comfortable and supportive for years to come.
- Do a final posture check after adjustments.
- Tighten any loose bolts or screws.
- Clean the fabric regularly to maintain appearance and hygiene.
By following these steps, you can transform your TC100 RELAXED Gaming Chair into a personalized ergonomic throne that supports your body and enhances your gaming performance.
