These are great.  Theyre comfy.  They look like they sit low, but really, not bad at all.  They are springy chairs, not really a relaxing rock, but better than a stiff, still chair for sure.  WORTH EVERY PENNY.   Helpful info  I found chair covers for these that are working great on the big website that starts with an A and ends with a zon.  The chair cover brand is Vailge and title is Lounge Deep Seat Cover.  
I shopped for patio chairs for over six months before ordering these. These are the best value I could find,  and they are great.
