Waterproof Outdoor Swivel Chair Cover, 2 Pack-33Wx35Dx38.5H inch

Swivel chairs are wider and deeper than they look from the front, because the whole seat sits on a base that no ordinary chair-shaped cover accounts for. These are cut 33 inches wide by 35 deep by 38.5 tall for exactly that geometry, in heavy-duty oxford with a PVC coating on the back — the thick, scratch-resistant kind that shrugs off blown twigs and grit — and treated so rain stays on the outside instead of seeping through on a long wet night.

Both chairs get covered, since the package holds two. Each one fastens with click-close straps around the legs and an elastic hem cord drawn tight with a toggle, so the cover stays on the chair through the kind of gusts that send loose covers into the neighbor yard. An air vent takes care of interior condensation and wind lofting, and a padded handle at each side makes pulling the cover off for a sunny afternoon a short job.
