Can one sit in it?

No

Does it occur in the book Voyage of the Dawn Treader?

So, for review:
1. It is inanimate.
2. Most people own one.
3. It is not an appliance.
4. It may be found in the kitchen, but not because it's a kitchen item.
5. It does appear in Narnia.
6. There is one in a book Eustace stars in.
7. Despite my earlier answer, it is not for eating.

Also to review--
8. Not sharp
9-10. Not a flashlight or key
11. Not metal
12. Not a container
13. Not exclusive to Narnia
