Sleep Number King Cover for m7 - brand new

This sleep number m7 mattress encasement has never been used. I took it out of the flimsy plastic to take photos. We purchased the cover as a backup and never used it. Now we have a split king. It would probably work as a protective cover for any king matress. Please look at the photos to ensure this is the correct cover for you. From a smoke free home. Questions? Leave a comment below!
