I actually use these on my patio chairs rather than cushions as can sit out in all weather. This moulded seat looks very much like the ottersports white plastic one that was standard in glassfibre kayaks for many years. Riber have recreated in a softer rubber that has a bit of give. Can be fitted on sit on tops as well, or almost anywhere your bum needs a bit of a softer time.
I have just got a lot of RED in original model that dont have the new screw down points, so special price for these
