These cushions are just about as perfect as you can get, greatly increasing the comfort and visual appeal of outdoor seating areas.  The pattern is bright and cheery, the cover material is comfortable but clearly very durable, and the inner foam is quite cushy (although it could maybe stand to be a bit more dense).  It looks like the ties are well-sewn and probably quite durable, but I can't speak to their longevity just yet.  That being said, on a couple occasions we've used these without tying them down to the chair and they worked great even if they shifted around the seat of the chair a bit more than they otherwise would.
