I justmade cushions for my M 17. I purchased foam form a local furnature manufacturer, But you can get foam from a fabric store. The 4" is better as I think it is the origional size. I think there is a fiber material now in use for the bottom that may help with moisture. --- On Tue, 5/24/11, Ted Weidenbach <weid0069@umn.edu> wrote: From: Ted Weidenbach <weid0069@umn.edu> Subject: M_Boats: New Cushions To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Date: Tuesday, May 24, 2011, 10:52 PM So I am looking to get new cushions made for the inside of the M15 and I was wondering if anyone could give me their insight on a few questions. 1.) Do you think I need "Marine" foam? What is the difference between that and foam you'd see in a couch cushion? 2.) The upholster is asking if i'd prefer 3 or 4 in foam....Any thoughts on what is better to sleep on? I am also exploring the possibility for having cushions being made for the cockpit. Has anyone on the forum here done that and if so could you give a little background on what specifications you had them made to and how you like the cushions? Thanks! -Ted _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats When posting, remember that there is no privacy on the Internet!
