Last summer we purchased a Sprinter Chateau 24HL and quickly began searching for the booster cushions after seeing them in a Winnebago model.
All of the leads I found indicated cost ranging from $300-$600 for a set of two! After countless hours of searching I found a posting that said the cushions were no longer being offered so I decided to try and make my own!
With a road trip quickly approaching I wanted to get them made as fast as possible. The first cushion I took the time to tailor the sides, but time was running short and on the second cushion it ended up being a quick drawstring design.
I consider them prototypes and plan to redo them and make a few minor changes. Attached are a couple of pictures, which make the cushions look huge! They worked out great though and made all the difference in being able to enjoy and comfortably use the swivel chairs while parked.
