I need to re-upholseter 4 dining chairs with drop-in seats. The current drop in seat frames are very damaged and full of old tacks and holes so I want to replace them, I was thinking to replace with solid plywood but am tempted to try making a plywood frame with the centre cut out and using webbing to support the foam, to make the seats more comfortable.
Do we have a webbing stretcher? And if anyone has done anything similar I’d appreciate any advice. I feel a bit like a vandal for ditching the original seat frames but they’re very creaky and knackered and I’m guessing were never intended to last forever.
