we bought our 2015 3582RL in June 2021 and the "leather" recliners and sofa bed were beginning to peel. That turned into a full out shedding with the recliners. We wanted vinyl or leather, due to the pets that travel with us and liked the black color. we did not want powered since we do a lot of overnight boondocking on the road. It was difficult finding anything remotely available.
After a lot of searching, we ordered a "KVK PU Reclining Console Loveseat, Upholstered Sofa Recliner Chair, Manual Reclining Home Theater Seating with Storage Console Cup Holder, Arm Chair for Living Room Bedroom, Black Loveseat"
It arrived in four boxes that will easily fit through the 5er door and looks to be of decent quality. 5er is currently in the shop for some repairs, so we won't actually get them installed for a couple of weeks. Will update my evaluation then.
