Member of family had a very old Gplan suite stripped down and re-covered with new foam and modern fabric. Merebrooks West kirby. Cost getting on for nearly as much as a new suite (but she liked the frames shape and size. Looked fabulous when finished. It lasted about 6/7 years with very light use by a skinny person, then when it was moved to a new house with two heavier people,after just 3 mths, the foam seemed to give up the ghost and sink in, all along where your back should be supported . It never recovered and had to be replaced. Having seen that, personally Id never bother reupholstering, Id go for Plumbs covers , or a new suite.
