Description
Anthros Black
Serious Ergonomics. Stripped Down to Black.
The Anthros Black Ergonomic Office Chair combines an independently adjustable two-part back, pressure-distributing CloudFloat™ seat and five-mode tilt system in an all-black configuration built for everyday desk work.
Precision Posture System™ CloudFloat™ Seat Five Tilt Modes 4D Armrests Made in Grand Rapids 12-Year Warranty
A Different Approach to Ergonomic Support
Anthros separates pelvic support from upper-back support so each zone can be adjusted around the person sitting in the chair.
Understated by design. Anthros Black combines Onyx Athlon performance fabric with a Standard Onyx back for a coordinated all-black finish.
Anthros’s two-part back is designed to support the pelvis and upper back independently while you work.
Independent Pelvic & Upper-Back Support
The Precision Posture System™ lets you position the lower and upper supports separately to suit your seated posture.
Pelvic Support
The lower support is designed to capture and stabilize the pelvis, helping establish a supported foundation for upright sitting.
Tapered Upper-Back Support
The upper pad adjusts independently to meet the mid and upper back. Its tapered profile is designed to give the shoulders room to move while you work.
CloudFloat™ Seating & Pressure Distribution
The CloudFloat™ seat uses contoured foam with rear cutouts designed to shift pressure away from the sit bones and distribute it across a broader seating surface.
Separate University of Waterloo research comparison image; the Pittsburgh cushion testing described below used a bench-testing setup.
University of Pittsburgh Cushion Testing
Anthros reports the lowest peak seat pressure among 11 office and gaming chairs in a bench test performed April 5, 2025. The test used a rigid load indenter to compare seat-interface pressure.
Computational Spine Modeling
Anthros describes computational human modeling by Simuserv to evaluate its two-part back support and pelvic positioning. These findings come from modeling rather than measurements of spinal disc pressure in people using the chair.
Research information is reported by Anthros. Bench testing and computational modeling do not guarantee individual comfort or pain relief. Fit, comfort and pressure distribution vary by user.
Move. Focus. Decompress.
Choose from three locked working positions, an unlocked free-float range and full decompression for breaks.
−2° Active Mode
Locked slight forward position for focused or precision-oriented work.
1° Standard Mode
Locked everyday working position. The chair ships in this mode.
5° Decompress Mode
A lightly tilted locked position that can still be used during desk work.
−2° to ~8° Free-Float Mode
Unlocked movement between upright and lightly reclined positions. The available range varies with tension setting.
16° Full Decompress
Unlocked full recline for stretching, calls or a brief break. Not intended for focused computer work.
Tilt angles are approximate. Free-float range varies by user and tension setting.
Fine-Tune the Chair Around You
4D Adjustable Armrests
Adjust armrest height, width, depth and angle to bring cushioned arm support closer to your body and work surface.
Seat Height & Depth
Adjust the seating position around leg length and desk height. Position the back supports so you can sit fully back while leaving comfortable clearance behind your knees.
HPS Real-World Fit
A Premium Chair Still Has to Work with Your Workstation
Set chair height around the work surface, sit fully back, bring the keyboard and mouse close, and position the monitor so you can work without repeatedly reaching or leaning forward. Body proportions, desk height and workstation setup all affect fit.
If raising the chair to a comfortable working height leaves your feet unsupported, a separate under-desk footrest can provide stable foot support. This may be particularly useful for shorter users working at a standard-height desk.
Important tilt-fit note: The standard Anthros Black tilt spring is optimized for users approximately 150–300 lb. For users under 150 lb, Anthros directs buyers to Anthros Custom for a tilt configuration optimized for lighter bodies. Contact HPS to discuss the appropriate configuration before ordering.

Frequently Asked Questions
Does the Anthros Black have a headrest?
No. Anthros Black does not include a headrest. If head support is a priority, HPS can help you compare other ergonomic chairs with headrests.
What if I weigh under 150 pounds?
The Black configuration’s standard tilt spring is optimized for approximately 150–300 lb users. Contact HPS before ordering to discuss the lighter-body tilt configuration available through Anthros Custom.
How do I know if I need a footrest?
If your chair must be raised for comfortable desk work and your feet no longer rest securely on the floor, a separate under-desk footrest can provide stable support and help you remain seated back while typing and using the mouse.
What is the difference between Anthros Black and Anthros Custom?
Both use the core Anthros ergonomic platform. Anthros Black provides a set all-black configuration, while Anthros Custom offers broader finish, upholstery and configuration choices.
