Bicarb of soda diluted with some water and rub/spray on. It will neutralise the smell rather than just cover it like Febreze does. If you can put the chair in fresh air for a while as well, it will help
How can adding vinegar to a bicarb of soda solution work? Bicarb works because sick is acid and bicarb is alkaline, so they neutralise each other. Vinegar is acid and will neutralise the bicarb before it gets a chance to neutralise the sick acid! [confused]
