Product arrived about a week after ordered. It is lightweight and made from a fabric, not plastic, which is nice. The zipper is strong enough. We were putting it on a heavy memory foam mattress and at one point, it appeared that it might year, but there were four of us putting it on, so we were able to maneuver the weight and it did not. Would have preferred something a bit stronger, and am not sure how well it will hold up over time, but it's okay for now. Might be better for a lighter mattress. Seemed a bit pricey compared to others in brick and mortar stores.
