Adjustable Air Lumbar Support

The tCentric Hybrid Upholstered features an innovative air lumbar system that sets it apart from standard ergonomic chairs:

• Built-in air pump: Easily inflate or deflate lumbar support to your exact preference
• On-demand adjustability: Increase support when you feel fatigue, decrease for relaxed sitting
• Personalized comfort: Fine-tune support throughout the day as your needs change
• Targeted lower back support: Focuses pressure exactly where your lumbar curve needs it

• No tools required: Simple pump mechanism adjusts in seconds

This air lumbar technology is especially beneficial for users with chronic back pain, those recovering from injuries, or anyone who wants maximum control over their lumbar support.

Fully Upholstered Dual-Curve Backrest

Unlike mesh chairs, the tCentric Hybrid Upholstered features a premium fabric backrest with advanced ergonomic contouring:

• Dual-curve design: Hugs your back for superior lateral support, preventing side-to-side slouching
• Full upholstery: Provides cushioned comfort and warmth compared to mesh alternatives
• Lumbar and thoracic support: Supports both lower and mid-back for complete spinal alignment
• 19" W × 25" H backrest: Generous size accommodates various body types

• Premium fabric: Open House Black Onyx upholstery is durable and easy to maintain

The upholstered backrest is ideal for users who prefer the feel of fabric over mesh, work in cooler environments, or want a more traditional executive chair aesthetic with advanced ergonomic features.

Advanced Multi-Tilt Mechanism

The sophisticated multi-tilt mechanism provides unparalleled adjustability for dynamic, healthy sitting:

Tilt Functions:

• Infinite lock free-float: Lock the chair at any recline angle for personalized support
• Free-float tilt: Recline smoothly with adjustable spring tension to match your body weight
• Forward tilt lockout: Engage forward seat tilt to relieve under-thigh pressure
• Independent back angle adjustment: Set backrest angle independently from seat tilt
• Adjustable spring tension: Customize recline resistance to your preference

Why multi-tilt matters:

• Encourages position changes throughout the day to reduce static muscle loading
• Forward tilt option improves circulation for taller users or those with leg issues
• Independent back adjustment allows personalized lumbar support at any recline angle
• Free-float mode promotes micro-movements that reduce stiffness and fatigue
• Infinite locking provides stable support when you need to focus

The tCentric Hybrid seat is engineered for all-day comfort with advanced foam technology:

• Dual-density molded polyurethane foam: Prevents "bottoming out" even after hours of sitting
• Contoured design: Reduces pressure on sit bones and distributes weight evenly
• Waterfall front edge: Eliminates under-thigh pressure and improves leg circulation
• 2.5" seat depth adjustment: Slide seat forward or back to match your leg length

Air Lumbar vs. Standard Lumbar Support

Why choose air lumbar?

• Infinitely adjustable support that adapts to your changing needs
• Increase support when you feel fatigue or pain developing
• Decrease support for relaxed sitting or breaks
• Perfect for users with fluctuating back pain or multiple users sharing a chair
• Provides more targeted, focused lower back support than fixed lumbar pads
• Easy to adjust without tools—simply pump to inflate or release valve to deflate

Who benefits most from air lumbar?

• Users with chronic or intermittent lower back pain
• People recovering from back injuries who need variable support
• Shared workstations where multiple users need different support levels
• Anyone who wants maximum control over their lumbar support
• Users whose support needs change throughout the day

Upholstered vs. Mesh Backrest

Choose upholstered if you:

• Prefer the feel and warmth of fabric over mesh
• Work in air-conditioned or cooler environments
• Want a more traditional executive chair aesthetic
• Prefer cushioned support against your back
• Need a professional appearance for client-facing roles

Choose mesh if you:

• Run hot or work in warm environments
• Prefer maximum breathability
• Want a more modern, technical aesthetic
• Like the responsive feel of mesh against your back

Both versions offer the same ergonomic adjustability, air lumbar support, and multi-tilt mechanism—the choice is purely about comfort preference and aesthetic.

Adjustment Guide for Optimal Ergonomics

1. Seat height: Adjust so feet are flat on floor and thighs are parallel to ground (knees at 90°)
2. Seat depth: Slide seat so there's 2-3 finger widths between seat edge and back of knees
3. Lumbar support height: Adjust backrest height so lumbar pad aligns with your lower back curve (typically at belt line)
4. Air lumbar inflation: Pump air lumbar to comfortable support level—start with moderate support and adjust as needed
5. Armrests: Set height so shoulders are relaxed and elbows at 90° when typing
6. Armrest width: Position arms to support forearms without forcing shoulders inward or outward
7. Tilt tension: Adjust spring tension so you can recline with minimal effort but chair doesn't throw you backward
8. Back angle: Set independent back angle for comfortable lumbar support in your preferred working position
9. Forward tilt (optional): Engage if you experience under-thigh pressure or circulation issues

Throughout the day: Adjust air lumbar as needed—increase support when you feel fatigue, decrease for relaxed sitting or breaks.

Frequently Asked Questions

How does the air lumbar pump work?
The air lumbar features a simple hand pump (similar to a blood pressure cuff) that inflates a bladder in the lumbar support area. Pump to increase support, press the release valve to decrease. It takes just seconds to adjust and requires no tools or electricity.

Which size should I choose?
Petite (4'10"-5'4"), Standard (5'4"-6'0"), or Plus (5'10"-6'4" and larger builds). Key factors are height, leg length, and hip width. Review our Chair Fitting Form for detailed guidance.

Will this chair help my chronic back pain?
Many users with chronic back pain experience significant relief with the tCentric Hybrid's adjustable air lumbar and multi-tilt mechanism. The ability to fine-tune support throughout the day is especially beneficial for fluctuating pain. However, consult your healthcare provider for medical conditions.

What's the difference between this and the mesh version?
The upholstered version features a fully fabric-covered backrest with air lumbar, while the mesh version has a breathable mesh back. Both offer the same ergonomic adjustability and multi-tilt mechanism. Choose upholstered for warmth and traditional aesthetics, mesh for maximum breathability.

Can I adjust the air lumbar while sitting?
Yes! The pump is easily accessible while seated, allowing you to adjust support throughout the day without getting up. This is one of the key benefits of air lumbar technology.

Is the upholstered back as supportive as mesh?
Absolutely. The dual-curve design and air lumbar provide excellent support. The upholstered version offers cushioned comfort while maintaining the same ergonomic benefits as the mesh version.

Can I use this chair if I'm over 300 lbs?
Yes! The tCentric Hybrid is certified for up to 350 lbs with the same premium features and 12-year warranty. Choose the Plus size for optimal comfort and support.

How often should I adjust the air lumbar?
Adjust as needed based on your comfort. Many users increase support during focused work sessions and decrease it during breaks or relaxed sitting. There's no limit to how often you can adjust it.

Can I return this if it doesn't work for me?
