if you do want new foam, check out THE FOAM STORE. they have the best prices I've found around here(kemah). Is the seatback too striaght, or the bottoms too shallow? Maybe you could go with thinner foam in the backs, or cut to a wedge shape. That would need only minor adjustments to the covers. For extending the bottoms....it can be done. As for the other. I don't have a table; I can put out lawn
chairs in my salon. I'm thinking of hanging a disco ball up in here; but, what I really, really want is a table! just sayin...
