Built for Bigger Builds. Powered Support. Active Seat Ventilation.
The LiberNovo Maxis Airflow Ergonomic Chair combines the larger Maxis seating platform with electric lumbar support, motorized OmniStretch, and Active AirFlow seat ventilation.
Designed around Big & Tall users, Maxis features a 20.5" deep seat, expanded armrest positioning, extended head and neck support, a Bionic FlexFit backrest, and five-position controlled recline.
What separates Airflow from Maxis Electric is its integrated centrifugal fan and ventilated seat construction, designed to circulate air through the seat during extended sitting.
For shoppers who do not necessarily identify with the traditional “Big & Tall” label, Maxis may also be worth considering for plus-size or larger body profiles that need more usable seating room.

Who Is the Maxis Airflow Best For?
Big & Tall users
Designed for customers who need deeper seating, greater armrest range, and dimensions developed around a bigger build.
Customers who want active seat ventilation
The integrated fan and airflow channels are designed to move air through the seat rather than relying on breathable fabric alone.
Customers who want the full powered Maxis package
Airflow combines electric lumbar support, motorized OmniStretch, and Active AirFlow seat ventilation in one configuration.
Longer legs or larger body profiles
The 20.5" seat depth and broader armrest adjustment may provide a more appropriate fit than shallower conventional ergonomic chairs.
Extended desk use
A strong option for long work sessions when both dynamic support and additional airflow through the seat are priorities.

Designed Around Bigger Builds
Maxis was not developed simply by increasing the weight rating of an existing LiberNovo chair.
The Series uses a deeper seat, larger backrest dimensions, extended head and neck support, broader armrest positioning, and a controlled recline system designed around the needs of bigger and taller users.
The focus is on usable dimensions and body proportions—not size or weight capacity alone.
20.5" Deep Seat for Longer Legs
The Maxis seating platform uses a 20.5" / 520 mm seat depth, compared with the shallower seating platforms used across LiberNovo's Omni family.
Additional depth can provide more support beneath the thighs for users with longer legs and more usable seat surface for larger body profiles.
Seat depth remains highly individual, so leg proportions should always be considered along with overall height.
Bionic FlexFit Backrest
LiberNovo's Bionic FlexFit Backrest uses a multi-part structure designed to respond as your seated posture changes.
8 flexible panels
Create controlled movement across different regions of the backrest.
14 dual-link points
Connect the flexible backrest structure and help it respond to movement.
16 ball joints
Add articulation within the multi-pivot backrest system.
Maxis Backrest Dimensions
| Shoulder Area |
430 mm |
| Waist Area |
520 mm |
| Backrest Height |

Electric Lumbar Support
Maxis Airflow includes the same electrically powered lumbar system used on Maxis Electric.
This gives you powered control over lumbar support while retaining the larger Maxis seating platform and adaptive backrest design.
For customers who regularly change working and reclining positions, powered adjustment can make it easier to fine-tune support without reaching for a manual control.
Motorized OmniStretch
Maxis Airflow includes motorized OmniStretch, the same powered stretching function offered on Maxis Electric.
LiberNovo describes OmniStretch as a gentle powered movement designed to help users relax and reset during extended sitting. Rather than functioning like a traditional vibrating massage chair, the system uses controlled motion through the backrest.
It is especially relevant for customers who want more than conventional ergonomic adjustments and expect to use the chair for both focused work and more relaxed sitting.
Dynamic Support That Moves With You
LiberNovo's Dynamic Ergonomics approach is designed around movement rather than one fixed seated posture.
As you change position, different parts of the chair are designed to continue working with your body through tasking, relaxed sitting, and reclining.
Extended Dynamic Head & Neck Support
Taller users can encounter office chairs where the seat fits but the headrest sits too low or lacks enough positional range.
Maxis uses an extended headrest with substantial vertical and forward/back adjustment to accommodate differences in height, torso length, and sitting position.
| Vertical Adjustment |
140 mm |
| Fore/Aft Adjustment |
120 mm |
| Published Fit |
LiberNovo positions Maxis neck support for users up to approximately 6'7". |
Maxis-Specific 4D Armrests
Armrest spacing can be just as important as seat depth when fitting a larger body profile.
Maxis uses armrests designed around its wider seating platform, with substantial adjustment in width, height, and fore/aft position.
| Fore/Aft Travel |
130 mm |
| Height Range |
128 mm |
| Width Range |
400–600 mm |
The broad range helps accommodate different shoulder widths while allowing the arm supports to be positioned more appropriately for the user and workstation.
Controlled Recline System
Maxis is designed to provide a smooth, controlled transition as you lean back rather than an abrupt drop into recline.
This is particularly useful on a larger chair, where predictable movement can make changing positions feel more comfortable.
Five Recline Positions from 105° to 160°
The Maxis backrest provides five lockable positions: 105°, 115°, 125°, 135°, and 160°.
105°
More upright positioning for focused computer work and tasking.
115°
A slightly more relaxed everyday working position.
125°
Useful for relaxed work, reading, or less intensive computer tasks.
135°
A deeper recline for breaks and relaxed sitting.
160°
The deepest recline position for resting or stepping away from focused work.
Complete Your Setup with the LiberNovo StepSync Footrest
Maxis Airflow adds active seat ventilation, but the workstation still needs stable lower-body support. The LiberNovo StepSync Footrest supports the feet when the chair is raised for desk work and complements the chair as you move from tasking into deeper recline.
Its two-level design keeps the function intuitive: use the lower platform for tasking and the upper cushioned level for added foot and leg support while reclining.
HPS Showroom Fit Note: In our experience, stable foot support can make it easier to remain seated back and maintain useful contact with the lumbar and backrest while working.
Matching StepSync versions are sold separately and are available to try with LiberNovo chairs in our Chicago showroom, subject to availability.
Active AirFlow Seat Ventilation
The defining upgrade on Maxis Airflow is its Active AirFlow seat ventilation system. A centrifugal fan works with internal airflow channels and ventilated seat layers to circulate air through the seating surface.
This is different from simply using breathable upholstery. The Airflow model adds an active powered ventilation system beneath the seat to help reduce heat buildup during extended sitting.
The system offers two fan speeds with one-touch control. LiberNovo publishes runtime of up to 24 hours on Low and up to 10 hours on High.
| Fan Speeds |
2 |
| Low Speed Runtime |
Up to 24 hours, per LiberNovo |
| High Speed Runtime |
Up to 10 hours, per LiberNovo |
| Control |
One-touch fan control |
Published runtime is based on LiberNovo specifications. Actual runtime may vary with use, battery condition, and operating conditions.
Six-Layer Ventilated Seat Construction
Airflow combines its fan system with a layered seat designed to let air move through the seating surface.
1. Breathable Fabric
The upper upholstery layer provides the seating surface while allowing airflow through the seat construction.
2. Silk Cotton Padding
Adds cushioning within the ventilated seat structure.
3. 3D Support Mesh
Creates a supportive, air-permeable layer beneath the upper cushioning.
4. Perforated Foam
Uses openings through the foam layer to support airflow through the seat.
5. Airflow Channel
Directs moving air through the internal seat structure.
6. Centrifugal Cooling Fan
Provides the powered airflow that distinguishes Maxis Airflow from Maxis Electric.

Compare the Maxis Series Side by Side in Chicago
Powered features are difficult to evaluate from a specification sheet alone.
At Healthy Posture Store's Chicago showroom, customers can compare Maxis Manual, Electric, and Airflow and experience the differences for themselves.
Sit in the same Maxis platform, then compare manual versus electric lumbar control, experience OmniStretch, and determine whether Active AirFlow seat ventilation adds meaningful value for the way you work.
The goal is not automatically to choose the model with the longest feature list. It is to determine which configuration best fits your body, workstation, preferences, and budget.
