Frequently Asked Questions

Sizing & fit

What size is the Cordia cushion?
It measures about 16″ × 13″ × 2″ — sized to fit most office chairs, dining chairs, car seats, and wheelchairs.

Which way does it go on the seat?
Place it with the contoured cut-out channel toward the back, so your tailbone sits over the relief channel and your sit-bones rest on the gel.

Will it work on my car seat, wheelchair, or office chair?
Yes — the non-slip base keeps it in place on both hard and upholstered seats.

Care & durability

Will it go flat like foam?
No. The medical-grade gel re-levels after every sit and is built not to bottom out or flatten over time.

How do I clean it?
Wipe the gel clean with a damp cloth; the cover is removable and machine-washable.

Is this a medical device?
No. Cordia is a comfort and pressure-relief seat cushion — not a medical device, and not intended to diagnose, treat, cure, or prevent any condition. If you have a medical concern, please check with your doctor.
