Outstanding slip cover, heavy poly-blend with matlasse look. I washed and dried mine before fitting on to sofa. I love that it's one piece. I made this purchase to protect my sofa from visiting toddlers, sandy swimsuits, etc. I would have no problem using this cover on a more permanent basis.  There was an odor of the poly fabric even after laundering but within a few days the odor has dissipated. I am completely satisfied with purchase and highly recommend.  Finally, I found Wayfair communication just one aspect of their fine customer service.
