Chair arrived in good condition by FedEx but only wrapped in thin fiber bag, no plastic, so luckily it did not rain that day and soak thru the box.  Chair looks and feels good, one leg screwed in a bit off kilter, still trying to get that on straight.   
I thought the description said that the seat cushion is removable --- to clarify this --  the fabric cover is attached to the chair, sewed right to it, however there is a zipper on the left hand side that might be unzipped around the fabric to remove the cushion from the chair if you wanted to get new foam.   So you can not flip it or vacuum under the cushion.
