Seatcraft Bellagio Theater Chairs - Home Theater Seating | 4seating
Our contact person at 4seating was Anna Hernandez 800-407-8665- x 309.
The recliners came in 2 pieces, it fit through our door fine (3010DS). This was something I had to consider when purchasing the recliners, along with the width of them. The seat belts are there, but would have to pull them through the seating. We travel just us two, so this was not a concern for us.
The 2015 FR models have theater seating as a option. FR will not retrofit 2014 or older models (search this thread for theater seating and read bclements response on the subject). If you want recliners you must do it on your own.
