Very sturdy material and large enough to cover my wicker sectional with cushions and wicker coffee table. It isn't deep enough to cover the furniture as set up normally. However, I just push the 2 sectional pieces facing each other with coffee table in the middle and it fits well. The draw string cord doesn't tighten it all over but I just tuck the corners under the furniture and it stays put.  It kept my furniture dry through several hard thunderstorms with high winds. I gave it 4 stars because it isn't deep enough to cover furniture as set up. I have a Forever Patio Hampton sectional with curved corner.
