We use and recommend only genuine outdoor performance Urecel QuickDry® foam for our outdoor cushions. Unlike normal foam, Urecel QuickDry® is reticulated foam produced by “hydro-blast reticulation” and has large, open pores that permit maximum water drainage and air circulation. It incorporates UreGard™, a special built in formula for anti-microbial protection, prohibiting growth of mould and fungi. This makes it the ideal foam for cushions made for outdoor applications. Urecel QuickDry® is available in various cushion firmness and may also be lightly over-wrapped with a non-woven fiber padding for that extra plush.
