    What is piping: Piping on a cushion is the thin fabric tubing that goes around the edges of the cushions. Piping is somewhat like a fine/small pipe that is around all the joins/ edges. It can provide a premium look and can be made in difference colours to provide a contrast. If that seems daunting you may like to know that most cushions use the same fabric on the piping as they do for the cushion.

    This is a no brainer, we don’t charge extra for quick drying foam so we’d suggest you pick it. Regular foam
    tends to go mouldy if it gets wet and isn’t in the sunlight. Quick drying foam is open cell foam allows the water
    to pass through quickly.

    Quick Dry Foam: Quick dry outdoor foam for an all-weather cushion.
