I owned a Human Touch HT 7250 ( twice the price- half the features).
The first time i sat in the IS Groove i was blown away...
This Chair delivers a great massage!
The Gao Sha foot massage is blissful - the back rollers are going right down to your bum cheeks -
The airbags squeeze nice and tight... wow!
Yes - the factory preset massage is a bit firm - I but a pillow in the lower back until i got used to it.
The support team is also very helpful - had a small issue and i got excellent mail support.
I rate that chair 10 out of 10

This chair has double the features of a chair twice the cost from Harvey Norman. I found the factory pre-set modes a bit firm at first, but I just used it in manual mode until I got used to it.
I had to replace a plastic part, but once we identified the part, they sent me a new one from the factory at no cost.
I paid the extra $ for the 5 year extended warranty, and so far I am happy with their warranty service.

Very, Very happy with this chair.

I have a slipped disk and nerve issues affecting my right side. After I reluctantly used this chair at our best friends house I was advised to use it for approximately 30 minutes, I woke up the next morning for the first time in years being able to move without much pain, I didn't need to stretch. AMAZING!
Comfort, all the different settings, stretching, feet - list goes on
