Hi Linzie,
I have a similar chair from Oakworks and do a few offices, corporate events and shows during the year - I used to do quite a lot, but spend more of my time in the salon these days. You can easily offer Indian head massage or adapt a back and shoulder massage for the chair, but if this is something you're really keen on I would recommend an On-Site Massage course, as you'll learn some amazing, unique techniques.
I now have the chair up at the salon on quiet days - it's a great crowd puller as the massage is very "visual" (if that makes sense). Also very affordable and accessible for clients who only want a quick 5 or 10 minute de-stress and don't want to take their tops off or get oily. Great at this time of year for Christmas shoppers!
