I have re-upholstered an old 70s egg chair. Having stripped it down and repaired the carcass (not sure of the construction but some sort of blown foam), I covered it in peel foam, then a fire retardant wool. I remade cushions for it out of 2" and 3" foam, and covered them in hide. How are the Fire regulations interpreted in these circumstances. I re-upholstered this chair as part of an upholstery course but am concerned as there is no Schedule 3 Interliner.
Also, I have been asked to re-upholster a set of dining chairs with drop-in seats. I will be replacing the foam and the fabric they want to use is 100% cotton. Do I need a Schedule 3 Interliner between the new foam and the cotton fabric.
