I had been looking to purchase zero gravity chairs all summer and these are even better than I hoped for.  It is so easy it is to get a customized fit with these adjustable chairs- you can recline in countless different positions.  And the chairs are durable and quality, with breathable material that doesn't make you sweat.  I was also pleasantly surprised at how easily the chairs fold down for compact storage.  And they are easy to transport in my car- 5 stars all the way!  I love them!
