This particular chair was around 60 years old, completely dried out which was the primary cause of the straps breaking. We did a slight respray with a leather friendly spray paint which dries flexible and not brittle. After that we saturated the leather with a liquid conditioner which soaked to the base of the leather and then we applied a thick leather paste which helped to smooth out the surface texture which had started to crackle. After 3 weeks of oiling most of the colour returned and the flexibility increased substantially. We also remade new straps from Italian belting leather which was strikingly similar to the original material. The cost to restore the leather was $450 and the straps cost $200 per strap.
