Firmer foam for dinette cushions and backs

[bobrapp]

When I bought my camper, I felt that the original mattress was too soft and I had the replace it with a firm (heavy) mattress. Both of our backs really appreciate it.

Now, it is time to look at the seats. Since I am tall and rather thin (you could say skinny), my buttox sinks right down to the plywood. I am looking for an inexpensive source for foam rubber. Any suggestions would be most appreciated.

I've purchased twice now from:

I found suitable foam at Florida Foam and Upholstery Supply. Custom cut foam and a delivered price of 173.00. Sure beats the crap out of that 450.00 price quoted to me by a local shop (fitting 90.00 additional).
