I added a 4”foam insert to my 2012 310 dancer. I made a template, gave it to my local canvass/upholstery guy and he cut it out of 4” stuff. It goes up to the bolsters, and stays fine. I had hinges at the locations where the flip up back rest, and where access to the stereo are needed. It works fine. I could have done it in any of the thicknesses the upholster guy had access to, but in my mind, 1” or 2” would not have done the job, and generally thicker is better, I’m over 6’ and 230lbs. We leave it set up all the time because we never used the v berth table we did use the little setee table, which we still can use. Wifey and I love it, it feels like a real bed. All told, probably spent $600.

We are in Tacoma, WA & we used an upholsterer who took the old cushions as a template used high end foam and covered with material we picked out. Not cheap but excellent job. About $1,700.

Try Handcraft Mattress Company in Ft. Lauderdale. They are the original supplier for Sea Ray. We just had a 9" made for our 01 460 Dancer and we love it.
