Received the chairs but I am disapointed, the back retainer mechanism is not firm. Matter of fact it slips all the way to its flat position when you lay on it. Is not a matter of weight as a normal person's weight is way below what the lounger chairs holds. Also they are kind of short as one must push back not to have the feet hang (I am 5'10"). Anyway, I am disapointed on this purchase as I bought 4. Use this information to educate yourself before you decide to buy some of these items. I am reviewing the return policy now. Cheers.
