Boat upholstery costs.. some educated opinions requested!!?

If you need new foam it will be expensive especially if you go for good quality. Just to recover with average cost materials would be in the hundreds - that might not be with marine quality material. It also depends on where you are and the services available there. We found a good upholsterer in an area where there is a lot of boating and paid about $700 to recover cushions for our main cabin - three were about 16" x 48", three backs about the same size (no cushion in the back - covered just one side), two backs about 24" x 24" and two cushions about 24" x 24". That included the material, which was just average material - not top quality. Foam gets to be quite expensive. So depending on where you are, you will run into quite a bit of money to do it well.
