Foam cushions distribute pressure passively — the foam compresses under the patient's weight and conforms to the body surface, spreading the pressure load over a larger area than a flat rigid surface would. Basic flat foam provides minimal pressure relief. High-density contoured foam with cutouts at the ischial tuberosities and sacrum provides significantly better pressure distribution by allowing the bony prominences to sit into relief zones rather than bearing the full weight load.

The clinical limitation of foam is that it is static — it does not adapt to movement or position changes, and it degrades over time as the foam cells break down and lose their pressure-distributing properties. A foam cushion that was appropriate at purchase may not be providing the same protection six or twelve months later. Foam cushions should be checked regularly and replaced when they no longer spring back after compression.

Right for: Lower-risk users who are mobile and reposition frequently. Short-duration wheelchair use — a few hours per day. Users who need a lightweight, low-maintenance option and do not have significant pressure injury risk factors. Not appropriate as the sole pressure management intervention for full-time wheelchair users with moderate to high risk.

Gel cushions — or gel-foam hybrid cushions — use a viscous gel layer that simulates the pressure-distributing properties of fluid tissue. The gel flows under pressure, redistributing load away from high-pressure bony prominence contact points toward lower-pressure surrounding areas. This produces lower peak pressures at the ischial tuberosities and sacrum compared to standard foam.

The trade-offs with gel: it is heavier than foam, which matters for users who transfer frequently. It is temperature-sensitive — gel is firmer in cold conditions and softer in warm conditions, which can affect both comfort and pressure distribution. And gel can migrate or "bottom out" in some configurations, concentrating pressure rather than distributing it. Gel-foam hybrids address this by using a firm foam base to prevent bottoming out while maintaining the gel's pressure-distributing properties in the top layer.

Right for: Users with moderate pressure injury risk who need better protection than foam but do not require the advanced pressure redistribution of air. Active users who reposition frequently and can benefit from the stable support of a foam-gel hybrid. Users for whom air cushion maintenance is impractical.

Air flotation cushions — the category ROHO dominates — use interconnected air cells that allow pressure to be redistributed dynamically as the patient moves. When a bony prominence presses down on one cell, the air flows to adjacent cells, distributing the load across a wider surface area. The result is the lowest peak pressures of any cushion type — and the highest clinical protection against pressure injury development for high-risk patients.

The clinical advantage of air is not just the absolute pressure reduction — it is the adaptability. As the patient shifts, leans, or repositions, the air cells respond and redistribute continuously. Static cushions cannot do this. For a full-time wheelchair user with high pressure injury risk, this dynamic redistribution is the difference between a cushion that works when the patient is centered and still, and one that works all day through all of the patient's actual movements.

Air cushions require maintenance: periodic inflation checks to maintain the correct air level for that specific patient's weight and anatomy, and inspection of the air cells for leaks. The correct inflation level is not "fully inflated" — it is the level at which the bony prominences are immersed in the cells without bottoming out, which varies by patient. Initial setup by a trained specialist is essential for air cushion effectiveness. A ROHO cushion inflated to the wrong level provides significantly less protection than one set correctly.

Right for: High-risk users — full-time wheelchair users, patients with history of pressure injury, individuals with spinal cord injury or other conditions affecting sensation and repositioning ability, post-prostatectomy or post-surgical patients with seating complications. The clinical first choice for maximum pressure protection.

Contoured positioning cushions — the category JAY leads — are anatomically shaped foam systems (sometimes with gel or fluid inserts) designed to support the pelvis in a neutral, stable position while providing pressure relief at key bony prominences. The contour of the cushion guides the pelvis and thighs into a position that supports upright posture, reduces posterior pelvic tilt, and maintains lateral pelvic stability.

This postural function is the distinguishing feature of JAY and similar contoured systems. A user who sits with a posteriorly tilted pelvis — sliding forward in the seat, rounded back, head protruding forward — is not just uncomfortable. They have impaired upper extremity function, reduced respiratory capacity, impaired swallowing, and accelerated spinal deformity development. The right cushion can correct or support against these patterns in a way that a flat or air cushion cannot.

JAY cushions also provide meaningful pressure relief through contoured foam that distributes weight away from the ischial tuberosities. The gel or fluid components in some JAY models add additional pressure redistribution at the highest-risk zones. The pressure relief is not as aggressive as ROHO's air system — but for users whose primary need is postural stability rather than maximum pressure protection, JAY's approach produces better functional outcomes.

Right for: Users who need postural support and pelvic stability — those with posterior pelvic tilt, scoliosis, tonal abnormalities, or significant trunk weakness. Active manual wheelchair users who need a stable, predictable base for propulsion. Users for whom some pressure relief combined with strong postural support is the correct clinical balance. Not the right choice for the highest-risk pressure injury patients who need maximum pressure redistribution.

The Quadtro Select is ROHO's flagship cushion — four independently adjustable air sections that allow the clinician to fine-tune pressure distribution across the left and right ischials, the anterior thighs, and the posterior zones. This section-by-section control allows compensation for postural asymmetries, pelvic obliquity, and differing pressure risk across zones — capabilities that a single-zone air cushion cannot offer.

The High Profile version provides greater immersion depth — appropriate for larger body frames, more severe postural asymmetry, or patients who need maximum air cell depth to achieve proper ischial immersion without bottoming out. The Low Profile version is appropriate for users who need a lower seating height — to maintain foot placement, propulsion mechanics, or to fit within a specific seat-to-floor height requirement.

Right for: High-risk patients who also have postural asymmetries or pelvic obliquity. Users requiring the maximum flexibility in pressure customization. Any patient for whom a single-zone cushion fails to address differential pressure across left and right sides.

The Mosaic delivers ROHO's core air flotation pressure redistribution in a single-zone configuration — one inflation point, straightforward adjustment, proven ROHO technology. For patients who need ROHO-level pressure protection without the complexity of multi-zone adjustment, the Mosaic is the right entry point into the ROHO system.

The single-zone design means the entire cushion inflates uniformly — there is no differential adjustment between left and right sides or between anterior and posterior zones. For patients with symmetric pressure distribution needs and no significant postural asymmetry, this is entirely appropriate. For patients with asymmetric needs, the Quadtro Select is the better choice.

Right for: High-risk patients without significant postural asymmetry. Users who need ROHO's pressure protection with simpler maintenance requirements. Patients for whom the complexity of multi-zone adjustment is a barrier to consistent correct use.

The JAY J2 is the most widely used JAY cushion and the reference point for JAY's clinical approach: a contoured foam base that guides the pelvis into a stable, neutral position, combined with a fluid pad insert at the ischial zone that redistributes pressure at the highest-risk area. The contour prevents the posterior pelvic tilt that causes users to slide forward and develop a sacral sitting pattern — the posture most associated with sacral pressure injuries.

The J2 is appropriate for a wide range of users — from active manual wheelchair users who need a stable propulsion base to full-time power chair users who need predictable positioning throughout the day. The low-maintenance design (no inflation checks, no air management) makes it practical for users and caregivers who cannot reliably maintain an air cushion system.

Right for: Moderate risk patients who need postural support as the primary goal. Active manual wheelchair users. Users for whom a ROHO's air management requirements are impractical. The starting point for JAY evaluation in most patients.

The JAY Fusion adds a layer of air to JAY's standard foam-fluid system, producing greater pressure redistribution than the J2 while maintaining the postural contour that JAY is known for. For patients who need more pressure relief than the J2 provides but still require the strong postural control of the JAY system — rather than transitioning to ROHO — the Fusion is the right clinical step up within the JAY family.

The Fusion is appropriate for higher-risk patients whose postural needs prevent a transition to a pure air cushion. It is also a common choice when a patient presents with both pressure injury history and significant postural dysfunction — where a ROHO alone would not address the posture and a J2 alone would not provide adequate pressure protection.

Right for: Higher-risk patients who need both enhanced pressure relief and strong postural control. Patients who have experienced pressure issues on a J2 but whose postural needs prevent transition to ROHO. Complex seating situations where both clinical priorities must be addressed simultaneously.

The JAY X2 is designed specifically for active manual wheelchair users — people who propel independently for extended distances and for whom the cushion's stability and energy efficiency during propulsion are as important as its pressure and postural properties. The X2's thinner profile and activity-optimized design supports efficient wheelchair propulsion biomechanics while maintaining JAY's postural contour and adequate pressure relief for moderate-risk users.

Active manual wheelchair users have different seating needs than full-time power chair users. Propulsion mechanics require a stable base that does not shift under asymmetric loading. A cushion that moves or deforms during propulsion increases energy expenditure and reduces propulsion efficiency — a meaningful quality-of-life issue for users who rely on manual propulsion for hours daily.

Right for: Active manual wheelchair users who prioritize propulsion efficiency alongside positioning. Users who need postural support without the height or compliance of a thicker foam system. Younger, more active users for whom daily propulsion performance is a primary concern.
