Built for Bigger Builds. Powered Support. Electric Control.
The LiberNovo Maxis Electric Ergonomic Chair combines the larger Maxis seating platform with electronically controlled lumbar support and motorized OmniStretch for customers who want more powered functionality built into their ergonomic chair.
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 the Electric from the Maxis Manual is its electric lumbar support and motorized OmniStretch. These powered functions make it easier to adjust support and activate LiberNovo's stretching motion during the workday.
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 Electric 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 electric lumbar support
Powered lumbar control lets you adjust lower-back support without relying on a manual mechanism.
Users interested in OmniStretch
Motorized OmniStretch adds a powered stretching motion designed by LiberNovo for comfort and relaxation during long sitting sessions.
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
Well suited to work, study, creative tasks, gaming, and other activities where both task seating and deeper recline are useful.

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.

Electric Lumbar Support
Maxis Electric replaces the Manual model's mechanical lumbar control with an electrically powered lumbar system.
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
One of the most important upgrades from Maxis Manual to Maxis Electric is motorized OmniStretch.
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
A powered ergonomic chair still depends on a properly supported workstation. The LiberNovo StepSync Footrest provides stable foot support when Maxis Electric is raised for desk work and complements the chair as you move through its recline positions.
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.
Multi-Layer Seat Construction
The Maxis seating surface uses a layered construction designed to combine cushioning, support, and breathability.
Maxis Electric uses the standard Maxis seat without the powered Active AirFlow ventilation system found on Maxis Airflow.
Customers who want electric lumbar support and OmniStretch but do not need active seat ventilation may find Electric to be the most balanced Maxis configuration.

Compare Maxis Manual, Electric & Airflow

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.
