The Azure sun lounger's foam insert, crafted with tubular foam, is engineered to complement the contours of its adjustable backrests and seat. Made from quick-dry foam, this insert features an open-pore structure for water to flow through easily. To protect the integrity of the foam, it is crucial not to expose the quick-dry foam insert without a cushion cover, as this can lead to dust and dirt accumulation within the open pores, potentially damaging the insert.
