Three seat cushions, each matched to how the person sits. Every Asiento is built around the pelvis. Choose the seat that gives the right foundation, then add only the support the person needs.
Start with what you see in the assessment
| What you see | Seat |
| Slides forward, or sits in posterior pelvic tilt | Ramped |
| Needs lower-limb support to hold a stable midline | Contoured |
| An active sitter who moves to reach and engage | Flat |
Ramped: holds the pelvis
Secures the pelvis in a neutral, aligned position and prevents forward sliding.
Consider when the user slides forward or loses pelvic position during the day, posterior pelvic tilt is present, or posture drops after 20–30 minutes.
Pair with a sacral pad and 4-point pelvic belt.
Contoured: our standard seat
Increased immersion and lateral support to the lower limbs for a stable, midline position.
Consider when the legs drift out of alignment or rotate, midline sitting is hard to hold, or the therapist wants a shaped base for stability.
Pair with hip pads and abduction/adduction pads.
Flat: freedom to move
A neutral base for active users, supporting functional movement and greater independence.
Consider when the user moves to reach, play and engage, and the priority is freedom rather than containment.
Pair with only what is needed. Hip, knee or lateral pads can be added to build support.
All three cushions work with the full Asiento accessory range. Cushion choice should always be confirmed through a clinical seating assessment.
Already have an Asiento? Upgrade the seat, not the chair
The new seat cushions give chairs already in service a fresh start, for the same user or the next.
- Respond to changing needs. Update the support as posture, tone or activity changes.
- Re-issue with confidence. Swap the seat to suit the next user after decontamination.
- Make budgets go further. Change one part, keep the chair and reduce waste.
Upgrading is simple
- Review the user. Has posture, tone or activity changed since the chair was issued?
- Choose the seat. Use our cushion selection guide to match Ramped, Contoured or Flat.
- Talk to our team. We will confirm the right cushion for your chair and help with fitting.
Ideal for equipment stores, schools and colleges, and therapy teams. Cushion compatibility depends on chair size and specification, and our team will confirm before you order.
