DID YOU KNOW...? AIREZ 2.0 open-lattice elastomer cushions don’t “chew up” skin, they actually protect it.
A common misconception is that an open lattice elastomer cushion might be harsh on the skin. In reality, it does the exact opposite, especially when compared to traditional foam.
Here’s why:
Lower coefficient of friction = less skin “grab”
Open lattice elastomer fibers have a lower coefficient of friction than foam, meaning the cushion moves with the skin rather than gripping it. Foam tends to “grab” the skin during small movements, increasing shear forces, one of the biggest contributors to skin breakdown. Elastomer lattices reduce that shear at the skin–seat interface.
AIREZ 2.0 elastomer cushion underwent ISO-standardized mechanical testing at the University of Pittsburgh. Horizontal stiffness testing was performed using shear sensors positioned at the ischial tuberosities (ITs).
Testing protocol included:
Measurement of initial shear forces
A pelvic-shaped indenter pulled forward 10 mm to simulate a sliding event in a wheelchair
Cushions Compared:
AIREZ 2.0 with Standard AirMesh Cover
AIREZ 2.0 with Dartex-Style Cover
ROHO Single Valve with Standard Cover
Why test against ROHO? It is well established in the seating industry that ROHO® cushions are known for low shear forces, which is why they are frequently recommended for individuals with pressure injuries or high risk for skin breakdown.
Findings:
Lower Initial Shear:
AIREZ 2.0 demonstrated lower initial shear forces compared to ROHO®.
Post-Sliding Simulation:
After the 10 mm indenter pull (simulated client sliding), AIREZ 2.0 and ROHO® performed nearly identically, values were within decimal points of each other.
What Does This Tell Us Clinically?
Reduced Initial Skin Drag
Lower initial shear means the cushion does not aggressively resist small positional shifts.
This reduces the “grabbing” effect at the skin interface.
Comparable Protection During Sliding Events
Even during a simulated shear event (forward pelvic migration), AIREZ 2.0 maintained shear performance equivalent to ROHO®, which is an industry benchmark product long regarded for low shear characteristics.
Tissue-Friendly Material Behavior
The elastomer lattice:
Has a lower coefficient of friction compared to traditional foam
Provides compliance with micro-movement
Allows controlled deformation without abrupt resistance
In practical terms: AIREZ 2.0 does not create excessive drag or “chew up” the skin during movement.
These findings suggest that AIREZ 2.0 can:
Provide clinically appropriate shear management
Perform at or better than a leading air-cell cushion
Offer a viable option for clients at high skin risk
89% air = true microclimate control
The open lattice structure is approximately 89% air, allowing:
Continuous heat dissipation
Multidirectional airflow
Fluids to pass through the cushion instead of pooling against the skin
This dramatically reduces moisture accumulation, skin maceration, and irritation.
Every micro-movement promotes ventilation
With every subtle shift, reach, or postural adjustment, the lattice:
Allows fresh air to circulate across the skin
Releases heat and humidity
Minimizes friction and irritation
Rather than trapping heat and moisture like foam, the cushion actively works with movement to protect the skin.
Heat + moisture amplify pressure & shear risk
It’s well documented that heat and moisture significantly increase the damaging effects of pressure and shear. By controlling microclimate at the skin interface, open lattice elastomer cushions reduce moisture and heat, some of the most critical but often overlooked risk factors for skin breakdown.
Real-World Outcomes We See Every Day
Active 25-year-old living in South Florida
After years on an air-bladder cushion, he reported severe heat and sweating that limited his sitting tolerance and negatively affected his quality of life. Heat and moisture management were critical due to his skin condition. After switching to AIREZ 2.0, he reported dramatically improved comfort, better temperature regulation, and longer, more tolerable sitting time.
Female with Rett Syndrome
Previously seated on a foam system that trapped heat and moisture, she experienced chronic skin irritation and recurrent infections requiring long-term antibiotics. After transitioning to an AIREZ back support, airflow and moisture control at the skin–back interface improved so significantly that she has been antibiotic-free for over two years, with reduced pain and healthier skin.
Bottom Line
Open lattice elastomer cushions don’t abrade skin. They:
reduce friction
manage shear
regulate microclimate
protect tissue
For users who have struggled with foam, gel, air bladders, or other lattice style systems, the difference isn’t just noticeable, it’s life-changing.
