Can I use a seat protector mat underneath my Clek seat?

ONLY the Clek Mat-thingy can be placed underneath your Liing, Liingo, Foonf, Fllo, Oobr, Olli, or Ozzi seat, as only the Mat-thingy is tested and approved for use with Clek seats.

Using similar accessories or products from other manufacturers could alter the performance of your car seat in a crash.
