I currently use a massage table for shiatsu. During a shiatsu session you may need cushions and blankets for warmth and as props.
For a first session there is time to talk briefly about general health issues, etc. I'm lucky to have this peaceful space at the back of my house to do shiatsu in.
I also practice from The Wellbeing Room, .Satyam Yoga Centre, Hawthorn Way, Cambridge and in the comfortable rooms at Women and Health in Camden London
