Roho vs Jay vs Vicair
vs Stimulite

The chair gets the attention. The cushion is what keeps you out of the hospital.

When you have a neurological diagnosis — SCI, MS, ALS, CVA — you sit in the chair 12 to 16 hours a day. That changes the math on every other piece of equipment. The frame matters. The wheels matter. But the cushion is the interface between your body and everything else. Pick wrong and you end up with a pressure injury that costs $50,000 to treat and months of lost function. Pick right and you buy yourself years of maintained skin integrity, functional independence, and fewer admissions.

This guide covers the four cushions most commonly specced alongside ultralight rigid-frame chairs: Roho Quadtro Select, Jay J2, Vicair Vector O2, and Stimulite. We go beyond the marketing language. No favorites. Just what each one does well and where it falls short. For the full framework on how cushion selection fits into a complete chair configuration, see the ultra-lightweight buyer's guide.

Roho Quadtro Select High Profile

The Quadtro Select High Profile uses interconnected neoprene air cells — no foam, no gel, no fluid pad. The ISOFLO Memory Control lets the user lock air into four independent quadrants while seated. Adjust left-right balance, anterior-posterior stability, or full-open flow — all without getting up.

Construction

Latex-free neoprene air cells. 4.25” cell height (High Profile). ISOFLAP valve for quadrant control. Two-way stretch cover. Hand pump, patch kit, and owner manual included. 36-month cushion warranty; 6-month cover warranty.

Ideal User Profile

• Impaired or absent sensation below the level of injury
• History of pressure injuries including DTI (deep tissue injury) and stage II–IV pressure ulcers
• Current skin breakdown or post-flap/skin graft recovery
• Inadequate weight shifts or low-to-moderate postural needs

Weight & Maintenance

3.5–3.8 lbs depending on size. Maintenance is active: requires periodic inspection of air cells and re-inflation. Plan on teaching the user or caregiver to check and adjust inflation — it is not zero-maintenance.

Real Tradeoffs

Roho is the gold standard for high-risk skin — it is not optional when sensation is absent and history includes wounds. But it requires user engagement. If your client is not going to check and maintain inflation, the protection degrades. Also: Roho is overkill for a low-risk, high-sensation user who just needs a lightweight everyday cushion. Reserve it for the clinical indication. Price range: $417–$534 retail.

Jay J2

The J2 pairs a closed-cell foam contoured base with a JAY Flow fluid tripad — a three-section fluid pad that sits under the ischials and coccyx. The base is anatomically pre-contoured with a seat well and femoral loading shelf. Available in standard (2.5”) and Deep Contour (4.5”) profiles.

Construction

Closed-cell contoured foam base (carveable and modifiable). JAY Flow fluid tripad with up to 3” of immersion. Cover options: ballistic stretch (standard), air exchange, or incontinence-resistant. Widths 14”–24”; depths 14”–20”. Weight capacity: 300 lbs (standard), 500 lbs (bariatric J2 Plus).

Ideal User Profile

• High risk for skin breakdown with moderate-to-significant postural needs
• Users with changing positioning requirements or asymmetric postures
• Tilt-in-space users or those who still have adequate sensation to self-monitor
• Anyone who won't manage active maintenance — J2 requires zero once properly set

Weight & Maintenance

Standard J2: 11.9 lbs (5.4 kg). Deep Contour: 6.27 lbs. The Deep Contour is lighter because the seat well is carved from a single foam block. Maintenance is zero once properly set — closed-cell foam does not compress over time, fluid tripad never needs refilling.

Real Tradeoffs

J2 is the workhorse cushion for mid-to-high-risk users who have postural complexity. But when skin risk is extreme — DTI, active stage III/IV ulcer, post-flap — the fluid tripad does not provide the immersion depth that an air cell cushion does. J2 is also heavier than lighter foam options. If your client is self-propelling and weight-sensitive, factor this in. Price range: $407–$553 retail.

Vicair Vector O2

Vicair uses SmartCells — small tetrahedron-shaped air-filled fabric pieces — in segmented compartments instead of open air cells or foam. The Vector O2 has nine adjustable compartments that can be fine-tuned while the user is seated. It is the most configurable cushion in this comparison.

Construction

Tetrahedron-shaped SmartCells in nine compartments. Available in 6 cm (low-profile for active users) and 10 cm (maximum pressure redistribution) options. Fully machine washable at 60°C without removing SmartCells — hang dry 5–6 hours. Lifetime warranty on SmartCells; 24-month warranty on inner cover. Max user weight: 250 kg.

Ideal User Profile

• Users with pelvic obliquity, rotation, or leg length discrepancy
• Amputees who need differential offloading
• Active users who want a lightweight, highly breathable cushion
• Incontinence situations where machine washing is important

Weight & Maintenance

725g (1.6 lbs) average — lighter than any foam or gel option in this comparison. Meaningful for active self-propelling users who are weight-conscious. Maintenance is low: once initially adjusted, requires no active maintenance, no inflation, no leak risk.

Real Tradeoffs

Vicair is best-in-class for active users with asymmetry who need a lightweight, low-maintenance cushion. It is not the right choice for users with high skin risk — the SmartCells do not provide the same immersion depth as air cells when sensation is absent. Also: the 10 cm version can increase effective seat height in a way that affects footrests and transfers. Check your chair configuration before speccing. Price range: ~$350–$600 est.

Stimulite (Supracor Honeycomb)

Stimulite uses fusion-bonded honeycomb — a single piece of flexible, perforated honeycomb material — instead of air cells, foam, or gel. The honeycomb cells flex under load to distribute pressure. The material is breathable and self-ventilating through the perforations.

Construction

Single-piece fusion-bonded honeycomb (Supracor). Available in multiple profiles: Slimline (1.5”), Classic (2”), Contoured (2.5”–3”), and Adjustable Contoured Elite. Machine washable and dryer safe. Antibacterial, antifungal, and odor-resistant by material properties. 2-year warranty.

Ideal User Profile

• Low-to-moderate skin risk with full sensation
• Users who prefer simplicity — no compartments, no cells to check, no pump
• People who run hot and need the ventilation the honeycomb provides
• Active users prioritizing minimal weight and easy care

Weight & Maintenance

~2 lbs (Smart model, 2” profile). Among the lightest cushions available. Maintenance is very low — machine wash and dry. No inflation, no compartments. The material is inherently antimicrobial.

Real Tradeoffs

Stimulite wins on simplicity, weight, and maintenance — the easiest cushion to live with once properly fit. But it is not appropriate for clients with absent sensation or high skin risk. There is no dynamic pressure redistribution mechanism — it provides good static load distribution but does not adapt to changing positions the way air or fluid does. Do not use Stimulite as the first cushion for a new T4 complete injury. Price range: ~$125–$300 est.

How We Pick: The Decision Tree

We work through five factors in order. Skipping steps is how clients end up with the wrong cushion. This same framework applies to every chair configuration in the ultra-lightweight buyer's guide.

Step 1: Skin Integrity Risk. Absence of sensation, history of pressure injury, active wound, post-flap, or DTI → Roho Quadtro Select. Moderate risk with intact sensation → Jay J2. Low risk → Vicair or Stimulite.

Step 2: Postural Complexity. Pelvic obliquity, rotation, leg length discrepancy, amputation → Vicair Vector O2 (9 compartments, adjust while seated). Symmetric posture → continue down the list.

Step 3: Sitting Hours and Self-Management Capacity. 12+ hours per day with low self-management capacity → Jay J2 (zero maintenance). Active user who will manage their own equipment → Vicair. Variable hours with high engagement → Roho.

Step 4: Environment and Hygiene. Incontinence, humid climate, institutional setting → Vicair (machine washable whole). Dry climate, individual home use → any cushion.

Step 5: Weight and Chair Configuration. Active ultralight user, self-propelling, weight-sensitive → Vicair (1.6 lbs) or Stimulite (2 lbs). Power chair user or minimal weight constraint → Jay J2. Clinical skin risk overrides weight consideration → Roho.

Honest Tradeoffs

When Roho Is Overkill: A client with full sensation, a sitting schedule under 8 hours, no skin history, and no postural complexity does not need Roho. They need a lightweight, breathable cushion. Putting a high-risk skin protection cushion on a low-risk user wastes money, adds maintenance burden, and can create a false sense of security. In these cases, Stimulite or Vicair Active is the right call.

When Jay Underperforms: J2 is not the right first cushion for clients with absent sensation and high skin risk — it provides fluid immersion, not air-cell immersion, and the depth is not equivalent. If you are treating a new T4 complete injury, start with Roho and reassess when sensation and skin history are established.

When Vicair Is Best-in-Class: For active users with pelvic asymmetry — especially post-SCI clients who have developed obliquity over years of sitting — Vicair is the most versatile option. The ability to adjust nine compartments while seated allows ongoing fine-tuning as the body changes. It is also the best choice in humid environments or incontinence situations where washing matters.

When Stimulite Wins on Simplicity: For clients who do not have the bandwidth to manage active equipment maintenance — cognitive impairment, limited caregiver support, aging with MS — Stimulite is the right call. The 2 lb weight, zero-adjustment requirement, and machine-washable design mean it will continue to work correctly for years without intervention. Do not underestimate the value of simplicity in seating.

Cushion selection isn't a guess. If you're a therapist referring a patient, the therapist referral page explains how clinical notes about skin integrity and sitting tolerance feed directly into the cushion recommendation.
