Those chairs  are  very good material. You can sit up straight or lay down easily,  very comfortable. The pillow on top helps my neck( i have neck pain problem) so usually with any chair to take to the beach or the yard, i need to bring small neck pillow, but  with this chair, I dont have to. I m 
 5 feet tall (I m a small size of  Asian :) ) and those chair are not too heavy not too big for me to carry around the house or the beach .. I m happy with those chairs.
