Nice job. . .! Looks like a lot of work but probably saved a bundle over having an upholsterer do it.
For those thinking of redoing their seat cushions I would recommend that they become knowledgeable with the TWO important characteristics of polyurethane foam.
Everyone understands density but the more important (in my opinion) factor is ILD (Indentation Load Deflection) rating.
Ask a good upholstery shop for samples of high ILD and various density foams and differences quickly becomes apparent.
I like an ILD of about 50 - and find it far superior to what most factory upholstery manufacturers use.
Furniture factories in general use a low ILD foam because at first blush, it feels soft and cushy - it makes the sale.
A high ILD on the other hand, does not feel soft and cushy at first feel. It's not so good for sales, so it's not, if ever, found as a standard upholstery material. (And it costs more.)
BUT, after sitting on the high ILD foam for a longer period of time, say an extended dinner with friends, food and drink, one will find that the high ILD foam cushion still feels comfortable.
When I get serious about replacing our camper seat cushions, I'll seek out an upholsterer and special order some 50 ILD custom cut cushions.
