Full disclosure, I have never been a fan of massage seats, they have always disappointed. Due to chronic lower back pain I bought this one on its recommendations and boy, it doesn't disappoint at all. Firstly it is well boxed with no wasted plastic and rubbish (which is important) and immediately ready to use. Though I read the instructions you really don't need to, the controls are very intuitive and easy to use. The back pad gives a firm but not painful massage from very low to a reasonable height. I am 6'4" so the top of the back massage is just below my shoulder blades, but my wife is 5' as the back pad covers her back well. I am not disappointed with this cover for myself as it works well and feels great. The neck massage is truly height adjustable and I can vary this from my shoulders to the top of my neck, once again a firm and comfortable massage. (NOTE, my 5' wife found the neck massage was too high for her and didn't use it. However this is not a serious problem as the neck massage on this is really a support for the back massage and if you really need intense neck massage you should get a massage pillow that you can lie on and not use this in a seated position...it works much better for the neck).I have never been a fan of vibration massage and I did not know this had air massage points so I was not worried about these. I sat down and tried the back massage (excellent) experimented with spot massage on certain points (works excellently) and played with the neck massage (very nice) and then I saw the button marked "Auto". I pressed this and...OMG...WOW...it just started to combine all the elements including vibration and air massage and I nearly melted. The total effect is beyond the sum of the parts and each work well together, constantly altering and changing slowly to give a relaxing but never boring massage. I now use these even if I'm doing a spot massage on my lower back as the added vibration and air squeezing etc all help you relax into the important bit of the massage. Given that you can set this chair to focus on one thing, or do several...or just go on auto it is very, very flexible. And believe me, when you press auto it just takes over and carries you away, it's honestly wonderful.For direct problems I would say this chair is most suitable for back issues. You can focus on lower back or mid back etc and get an intense massage. If you put a cushion behind the rigid back so that you are laying back on it at an angle of about 20 to 25 degrees then the pressure increases and the massage is more intense. For neck massage it is fine, it will definitely help, but as I say for more intense neck massage you are better with a massage pillow. However, to get the neck massage as an extra while your back is being relaxed is brilliant. The seat mechanisms, vibration and air massage, are very pleasant in association with the rest but are not in themselves very therapeutic so this is not for really useful for problems with the Gluts or leg muscles. (No massage chair would be good for that, it is a different area and probably needs manual massage). However the intense back massage, the decent neck massage and the overall relaxing and therapeutic feel of the whole thing working together is WAY beyond my expectations and this is the first massage chair I would recommend in any way, and I recommend it very strongly.NOTE; It is easy to fold the seat up and slide this into a small space when not in use, easy and quick to get back out and very intuitive to use with an excellent controller.If you have a sore back, or if you just want the option to sit down for 15 minutes whenever you want and be treated to a delightful massage and pamper then get this, you won't be disappointed.I am not connected to this company and this is a neutral and non-biased review based only on my personal experience.Jeremy
