Over the years I've tried both the "sourcing the parts and doing it myself" and also the "using professionals" route for rejuvenating car seats and never been entirely happy but on Tuesday I took my Evo 2 seat into a local trimmers for them to have a look at the saggy bolster and today I picked it up, repaired to a very high standard for the princely sum of
£20. So if you're in the Loughborough area then I'd recommend "Wells" of Shepshed, 01509 504 700 for similar work.
