I have a 35K 2019. The backs recline, however, they have a strong spring force to keep them upright. Be aware there is no adjustible tensioner. My wife (130 lbs.) cannot hold back the back. Was really disappointed when it was up in Decatur and they said the backs are not adjustible. I'm 220 lbs and I have to use pressure to keep them from coming up. Not comfortable.
