Categories by Material and Function

  • Foam:
    • Pros: Lightweight, inexpensive, low maintenance, and provide good stability.
    • Cons: Can compress over time ("bottom out") and may trap heat.
  • Gel (Fluid):
    • Pros: Excellent for pressure redistribution, temperature regulation, and comfort.
    • Cons: Tend to be heavier and may require occasional kneading to keep the gel evenly distributed.
  • Air-filled (Air cells):
    • Pros: Offer the best pressure relief and customization by adjusting air pressure, ideal for high-risk users.
    • Cons: Can feel unstable for transfers, require regular maintenance (checking for leaks/proper inflation), and risk complete failure if punctured.
  • Hybrid:
    • Pros: Combine materials (e.g., a foam base with a gel or air insert) to offer a balance of stability and pressure relief.
    • Cons: Maintenance needs can vary, and they may be less customizable than pure air systems.
  • Honeycomb:
    • Pros: Very lightweight, breathable, and durable with no maintenance required.
    • Cons: Offer only moderate positioning and skin protection properties. 
Other Classifications
Cushions can also be described by their shape or intended use, such as: 
  • Postural Support: Contoured or custom-molded cushions designed to correct or accommodate atypical postures like pelvic tilt or rotation.
  • Bariatric/Pediatric: Sized and constructed for specific weight capacities or developmental needs.
