This is not a zero gravity chair...it doesn't even reach the 170degrees as advertised. That said, it is a heavy large patio chair that tilts back. It is advertised as "Zero Gravity." Seriously, does this company know what that means? This is a pretty heavy chair to move and hard to operate. I just cannot recommend it.
On the positive side, it arrived two days early, but...it arrived with a damaged box and paint scraped off the chairs frame.
In addition to the chair, the process of reporting and returning was a mess. They ran me around then said the manufacturer had to deal with it and then the manu sent me back to Wayfair. I tried to update my review, but they didn't print it. Wow, this is not a company that I will ever do business with again.
