We have a 2015 DutchStar, the 2 captain seats were nasty when I bought it used in March 2020 with just over 16,000 miles on it. The rest of the furniture(2 recliners, couch, and dinette booth were decent but had wear on the seam piping. The maker of my seats was Villa, I was told the original owners of rigs from late 2014 to early 2016 were given an opportunity to get replacements, me being a second owner was SOL.
I asked Newmar what the cost would be get new replacement seats, they said $3,500.00/ea., or they could supply new exact-fit covers that I could install myself for $2,800.00/ea., obviously Newmar really likes their seats.
Long story short, I found an upholstery shop within 25 miles of home that recovered both captain seats and the both recliners for a VERY good price using a marine grade material that darn near matches the original seats.
