Go to your friendly foam shop and try some weights out. This is your opportunity to optimize for a softer bed rather than a hard seat. In my '85 the seat foam (thick sections) are about an inch higher than the back pad due to the plywood seat back and mounting bracket taking up about 1", and the foam there is thicker anyway. Again, for optimizing the bed, measure the exact thickness you need on the seat subtracting the plywood and bracket thickness. It should be 4" for the rear and 3" for the seat. You could go 5" for the rear pad, and 4" for the seats since you'll be making new covers anyway.

What's the conclusion of those who have done it? I'm thinking 36-46 lb compression, around 2.5 lbs per cubic foot type foam. And do I have it correct ( for the plain, not sculpted seats) that it's 4" thick foam all round? Not that interested in memory foam topper, just a plain old good quality foam. Thanks Alistair |
