I received my order of the Nia all-weather 7 piece rattan sofa seating group with cushions. This set is intended for use outdoors. The seat cushions have little knobs that can be attached to the rattan strips to prevent them from blowing away but the back cushions don't. In my humble opinion that is a HUGE design flaw and I am very unhappy about that. It was not specified on the page where the set was advertised.
