Hi there star04,
I thought I'd elaborate on my previous reply, now that I'm not so manic. The techique that is used in chair massage is completed diferent to the holisitic/swedish massage. In chair massage you use thumb and elbow pressure applied to various acupressure points in the upper body and glutes. No oil is used and the client is fully clothed. It's a fairly short massage (15-30 minutes) and both relaxing and energising. I have no experience of acupressure so cannot say it compares. Hope that's more helpful.
All the best,
Ancona
