While in Quartzsite years ago at the RV show, I stopped and talked to these folks that had several recliners and sofa's on display. They specialized in RV furniture and understood about sizes. I ended up ordering 2 recliners from them that replaced my original ones in my 2012 model 3582. Fit perfect and are 10 times more comfortable and look nicer. I still have to move and turn them when the slides come in. The company has been there every year at the show and I would recommend them. They operate out of a store near Eugene, Or, have a great website, and anything can be shipped to you.
