Hi, I have a pair of GBS Seats in black. Both are in really good condition and one has had a professional repair from a local upholsterer to the pipping on one side. I have a link to the KitSpares site below - these seats are 6 years old, have no tears apart from the piping on one which has been repaired. The springs have a little surface rust on them so will clean up ok. Seats are on runners but I had cut the adjuster arms as they snagged on the floor of my Zero - if this is not to your liking, then just get a new set of runners or bolt to the floor. Hopefully the links below will send you to the images of the seats:
