The one with the zaisu

A zaisu is a Japanese chair with no legs but a normal chair back. Usually found in traditional rooms with tatami mats, they are perfect for relaxing under heated tables.

Cheap and easy to store (this one will lie flat under the sofa) they provide extra seating when you need it but most importantly this one will keep me warm in the winter when I put my heated carpet down. Assuming I can convince his lordship it's not his!
