our adirondack chair with pull-out hassock (from wayfair, natch) stays outside under our pergola (ALSO from wayfair, and we love it) and i wanted a sturdy, well-anchored cover...one that would not get blown away in winter winds, that would be secure around legs and arms.  this cover is perfect.  it has adjustable ties to help hold the cover in place, as well as holders to wrap and secure it at the base.  this could not have been more perfect for what we needed.
