If there were a personal possession I'd like transformed into a service, I think it might be clothing rather than furniture.

With furniture, once you have the appropriate pieces, you don't really need to do much with them. Also, it's easy enough to buy / sell furniture as needed, i.e. whenever you feel like moving.

As for clothing - with changing seasons, drycleaning, different dress codes, polishing shoes, etc, etc... wish there were something where I could order the next week or two's clothing for hire, and send it back dirty, and let someone else figure out when it needs replacing, polishing, etc.
