Question: I like strong massages, does this chair actually massage (shiatsu/rolling) or does it just vibrate?  Thanks
Document: I would recommend it. Easy to assemble and heat and vibrate actually works. It was for my 93 year old dad and he loves it.
I saw a lot of bad reviews but its awesome. It spins and has good back support. I like that the arm rest are low. It feels like a natural position. The vibrate has 5 different intensitys so on 1 its real quiet. The auto setting makes it vibrate in a random pattern that is awesome! The heat function is down at the lower back right where it is suppose to be. I also like that the ottoman plugs in and  vibrates.Easy to put together.
I play my xbox while using this chair. It is a very comfortable chair. I am happy with the quality. It has a heat function and I can't  tell whether or not any heat actually is produced. The vibrating massage is more annoying than relaxing.
When I first go it, and saw all the pieces, I was nervous about putting it together, but it was actually quite easy. Once you line up the back to the seat perfectly, you just screw it in, and there you go. Also, the wires are very simple to connect... color coordinated. It took around 15 minutes and then I was enjoying the chair. I love the heat and massage.
Most people have that too tight - rhomboids among many others. This chair does nothing for them. It is nice on the thigh and calves. ish.Also the heat should be along the same lines of a heat blanket; it should get toasty warm so it can actually warm the muscles. I would describe this chair as lukewarm or 'not cold'I should have known for the price. I mean it's a nice looking chair - tricky to assemble, but nice looking. As far as it's massage properties?
the massage feature is cool but is more of a vibration  than anything else and really isnt great.my advice save up a lil bit more money and get a chair that you will actually enjoy!
That's not a hundred percent accurate. I actually bought two by accident but decided to keep both. they're not the greatest massage chairs but for the cost they are pretty good.
At the price it's selling at, why not take a chance.Well, this chair fit me like a glove (my wife thinks I have a weird body). I love it! As a swivel recliner you'd be hard pressed to find anything better at this price. I don't care for the massage part but the heated lower back is very nice. The chair and ottoman are lightweight so they do tend to slide on a hardwood floor, which is annoying. On a carpeted floor, no problem.
it`s a nice chair for the price. not as comfortable as a lazy z boy but still you can sit in It all day and night comfortability. massage feature is great. the picture is a little decieving. the chair isn't as much of a bucket seat like the picture shows. still its a nice chair. I love how far back it reclines. only thing id change is make it a deeper bucket seat or the arm rests higher. I feel when you recline the arm rests are too low.
I bought it because of someone elses review, she was right easy to put together,good quality and actually light to m ove around but  still nice and sturdy. Very comfortable--just what I was looking for. Did not really want the massage part, but I have actually used it.
