I just started making my seats. Was intending to do the 3 layers of "comfor foam", but when I laid that up and sat in the airplane and close the canopy, it turns out that I'm just too tall, even with the 650 canopy I installed on my XL. I ended up going with a layer of green foam over the aluminum seat pan, and then on top of that I did one seat with a single layer of blue foam, and the other seat with a single layer of pink. I sat in both of them for a long time to see if they became uncomfortable. Felt ok. I'm making my seats interchangeable, so I can test each one, and then the one I like best (blue vs pink foam) is the one I'll go with. - Pat -------- Patrick XL/650/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=293660#293660 ________________________________ Message 3 _____________________________________ Time: 10:10:18 AM PST US From: "Paul Mulwitz" Subject: RE: Zenith-List: Re: upholstery Hi Pat, The folks at Oregon Aero came to one of my EAA chapter meetings and gave some impressive demos of the memory foam. The one that left the biggest impression used a large steel ball (like the kind in old pinball machines) and bounced it off a variety of rubber cushions. When it hit most of them it bounced, but when it hit a thin sandwich of pink and blue memory foam it just about stuck. This showed how much power the memory foam has to eliminate jarring vibration to the bottom of your spine. I suggest you consider this vibration issue as well as sitting comfort when making up your seats. A thin layer of both types of memory foam might work a lot better to absorb shocks than either one can alone.

It is the ultimate in comfort. On my t rip to OSH last year in my 801 one long day of 13 hours of flying was ma de a non event by using the memory foam, it is more expensive but you al l will love it for the life of your plane and is well worth the addition al cost.
