Matrix 3D Printed Solutions
Two paths to your custom shape - One consistent AIREZ
AIREZ, whether via a shape capture app or our Tailored-by-Number method, Matrix converts your data into a precision 3D printed lattice, delivering uniform comfort, stability, pressure relief, and structural integrity across the cushion or back support.

Seating Solutions Using
Shape Capture
Matrix Seating USAs AIREZ line of custom cushions and back supports utilize a scan app, such as Matrix Keen3D, Scaniverse, or Polycam 3D Scanner, that creates OBJ files. From there, high-resolution 3D printing ensures consistent, millimeter-true accuracy across the surface, while the open lattice provides 360° airflow that flushes heat and moisture for cooler, drier sitting.

AIREZ Product Line
AIREZ 2.0 Cushion
Custom 3D printed cushion using the Golden Ratio, a proprietary blend of soft, medium, and firm elastomer fibers in a single multi-density lattice. This precision-engineered design delivers targeted pressure relief, strength, and postural stability while maintaining long-term shape and comfort.
High-resolution 3D printing ensures consistent, millimeter-true accuracy across the surface, while the open lattice provides 360° airflow that flushes heat and moisture for cooler, drier sitting.
The hydrophobic material allows fluids to pass through rather than absorb, with a built-in collection tray that prevents leaks, even when tilted or reclined, and cleans easily. Customizable pressure-relief zones can be tailored for individual protection and comfort, reducing the risk of pressure injury.

AIREZ Back Support
3D printed from a proprietary high-strength nylon, providing exceptional durability, flexibility, and precision.
Using a shape capture scan app, each back is custom-tailored to the individual’s anatomy, defining exact areas for added relief and targeted support to address postural asymmetries, rib humps, and other gibbous deformities.
Made with the same open cell design as the AIREZ 2.0 cushion, 360° airflow flushes heat and moisture for cooler, drier sitting.
Integrated T-nuts can be placed directly into the shell for attaching postural supports such as chest straps, laterals, and headrests.
Compatible with both manual and power wheelchair bases, AIREZ Back Supports offer a fully customizable balance of support, adjustability, and comfort.
Full Body AIREZ System
Total Customization. Seamless Support.
The Full Body AIREZ system represents the highest level of individualization in seating technology, a comprehensive, fully contoured system that captures and supports the unique shape and posture of each user from head-to-toe.
Built using advanced AIREZ nylon material the system delivers precision fit, superior pressure redistribution, and unmatched airflow across every surface of contact.
Head-to-toe shape capture: Each system is digitally molded to the user’s full shape, ensuring precise postural alignment and even pressure distribution.
Ideal For
Complex postural presentations (neurological or musculoskeletal)
Users requiring full trunk, head, and lower limb support
Pediatric through adult populations

Tailored-by-Number
Matrix Seating USA's PROTEUS line of cushions and back supports require no scanning technology. Using key body measurements taken by a therapist or ATP, each cushion is custom-built to the individual’s dimensions. This method removes the need for technology in the field, offering flexibility and ease of use.
*Precision may vary slightly due to differences in human measurement techniques.
PROTEUS Product Line
PROTEUS Elastomer Cushions
Delivers the same custom benefits of AIREZ technology through a simplified Tailored-by-Number approach.
PROTEUS elastomer cushion utilizes the proprietary Golden Ratio blend of soft, medium, and firm elastomer fibers in a single multi-density lattice, delivering targeted pressure relief, strength, and postural stability while maintaining maximum airflow.

PROTEUS Foam Cushions
Polyurethane (PU) open cell foam: porous, cellular structure that is compressive and breathable and allows for a soft, comfortable end feel.

Relief+ for more immersive properties for skin protection
Optional ultra gel insert at pelvic well. Ultra gel is a zero rebound gel that allows for near perfect shock absorption and is impervious to the cold.
PROTEUS Nylon Back Support
The PROTEUS Back Support offers the same advanced AIREZ nylon material and performance benefits, strength, flexibility, and precision, without requiring a scan app. Tailored-by-Number allows ATPs and therapists to take key body measurements to create a custom-fit back support matched to the client’s dimensions.
Offered with three shell options and same liner and cover options as the original AIREZ back support.
Back Shell Options
Matrix back supports were engineered for unmatched airflow through its open lattice structure, providing true 360° ventilation. However, because every client’s needs are unique, multiple back shell options are available to balance airflow, appearance, and stability.

Original
Maximizes airflow for the coolest, driest sitting experience. The new design provides exceptional strength and stability; strong enough to withstand tremors, tone, and spasms, eliminating the need for a rigid outer shell.
Smooth
Features a refined, smooth lattice for a more traditional look and easier cleaning, though airflow is significantly reduced.
