This Zero Gravity Chair is so comfortable, for simply relaxing, reading or doing whatever. Especially for medical purposes where the zero gravity is needed! There are silver locking rings on both sides of the chair that need to be open for adjustments that also lock in place and a side tray for a drink, phone etc, nice plus! The cushion, included, is reversible and kept its original shape and color after washing. There is also a “pocket” at the bottom of the cushion, maybe for a book The cushion doesn’t quite stay tied to the top, but the neck cushion, that’s included, helps to keep it up. It has definitely withstood bad rainy days and maintained its stability so far. I definitely recommend this lounge for its functionality and comfort.
