I have a Newfoundland dog. Who drools over everything loves, to put her head on my armrest. Hes comfortable chair cover, protects my chair and all except for about an inch and a half of the top of my armrest. If I take the time after I close the chair again I can cover the armrest with the chair cover. My chair is electric and it moves in different ways feet and lumbar head The chair cover stays fastened through all of these positions.
