Water-repellent vs. Waterproof:Our XXL pallet cushions are water-repellent, which means that the product is able to resist the penetration of water to some degree but not entirely (100% being waterproof). Summer bed cushion covers are made from 90% water-repellent polyester which limits penetration of water and rain. Although cushions are made with high quality outdoor fabric, we advise customers to avoid excessive exposure towards water and rain.Biiiig Pillows are made from 100% polyester velvet and are NOT water-repellent. ==> Extra large pillows should always be stored in dry areas.
