Never invest in outdoor furniture that suggests you should bring in the cushions. That is not true outdoor furniture. Osier Belle cushions can stay outdoors, all year round, no problem at all. They will take time to dry in heavy storms but will not mould (unless a food source is not removed or the cushion is not properly aired). Every element in our cushions has been chosen for their purpose. These include our 100% solution dyed acrylic fabrics, Urecel Quick Dry Foam, YKK non-corrosive zips and Serafil outdoor thread.
