Bridget’s just foam. Looks original. Still good, 30 years and 35,000 miles later.

Allen,

Mine is just foam as well and still holding up, but if you can figure out a way

to use springs you will be happy on long trips – one hour and my butt is

killing me.

Yes they do Ed.

From New Jersey, my Duchess, with it’s foam only seats, has made round trips to Indianapolis and Cincinnati, spent weekends on rallies and club trips in New England adn of course made numerous round trips to Carlisle.

We need to have a talk with Dale and Ringo!

The previous owner of my MiGi cut a big hole in the under-butt board and put a rubber diaphram or strap across the hole to soften the seat a bit. I replaced the board with a solid piece and recovered it and thought that I had improved things until I drove it for a half hour and got a bruised butt. I also didn’t like sitting that much higher.

So… I cut a hole in the new board and attached the rubber under seat diaphram from an MGB under the hole. Feels a lot better!

I’m tall and need to hunker down a bit or the wind coming over the windscreen will blow my head off! I also have no butt padding ( I’m skinney)

I did nothing to the passengers side. as my mate is well padded and short!!! Maybe I just don’t care enough?  

 Here is my solution. My London Roadster has a bench seat with holes cut out under the driver and passenger.After about an hour in the seat I would begin to feel the edge of the hole thru the foam as the area beneath me would sink deeper into the hole in the plywood, I used screws to fasten a piece of sheet metal to the lower side of the board.This allows the foam to sink just enough to be comfortable but not deep enough to feel the edge of the hole. The battery is under the right side of the seat so I insulated the positive terminal to avoid the risk of a fire though I have an inch of clearence.

 I have been pondering the seat question for awhile myself. For a lazy mans solution, I put a stadium seat cushion between me and the seat for an over 30 mile drive (may not be purty, but it helps). I have thought about cutting out the middle section of the seat board leaving about 2″ around the edges. Then taking some chair webbing like the aluminum lawn chairs use and weaving it in. I am not sure what would be gained would be worth the trouble Anyone want to try it 1st and let me know if it works?

There are several places  I’ve used medical stores wheel chail pads and used a stiffer foan for foundation. Also an outfit by the name of foambymail diffent types and shapes. Had a company by the name of bestwayfoam send me some for my bike seat I like these guys. and found this http://www.become.com/seat-foam-replacement different types

I’d mock it up first with a homemade pine box before trying it on the kit fiberglass

Update:

I decided to try a fix on my seats over the weekend using seat strapping I bought at a upholstry shop. I cut out the center of my seat plywood and used the stapping underneath – seems to work real well. I will need to take it on a long drive when the weather gets better – I may need to tighten up the straps a bit if I sink down to much. I made it so I could tighten up the staps w/o to much trouble. I also am thinking of removing the metal tubing in the fiberglass seat stand so I would have heated seats in the late Fall and early Spring.

Will try to post some pictures tonight.

I’ve tried several types of foam and so far NONE have held up for much over and hour.  I’m in the process of cutting in the hole idea and going to try a heavy canvas materal or a web then a 1/2 in thick very firm (almost solid) foam then the original foam and 1 in of memory foam.  The wife has suggested just using something like a bean bag chair cusion.  Gotta do something. 

Sorry – didn’t get the pic’s posted last night – will get my son to give me a hand when I get home today.
