I bought my first All33 chair for my craft room and instantly fell in love with it. After a couple weeks my oldest son sat in it and "borrowed" it. I ordered a 2nd chair for my craft room, and then my husband sat in it and fell in love with it so, we moved it to his home office, and I ordered a 3rd one. I have a feeling when my youngest son comes home to visit, he'll want one as well. For reference, I'm 5' 2.5" and the men in my family ar 6'3"-6'6" and it fits all of us perfectly. It's a miracle chair.

I instantly found myself spending all my time in the all33, replacing both my soft leather lounge chair and my massage chair. I found that Incredible! After the first day my lower back felt much looser and I was not sore after standing for the first time. Why would I spend all my time in this one smaller chair? The results explained it all! I’m very impressed with the quality!

I was very skeptical about spending this kind of money on a chair but I do work 9 hours a day in one and figured most of my back pain probably stems from that. I've had the chair for a few weeks now and this is honestly the most comfortable chair I've sat in. The support is excellent and I notice that I'm sleeping better at night as well. Overall, I would purchase this again without any apprehension now knowing what I know.

I’ve had this chair for almost a year. Before this chair, I could only sit at my desk for about 20 mins and when I got up to walk around my hips and low back were stiff and painful. If you look at the reviews, they seem to be too good to be true. But after having this chair for a year, I know that these are real. The moving seat and it’s design means relief for your tail bone, low back and hips. When the chair comes, they give you a seated exercise that strengthens your core by purposely making the saddle portion move. I usually do that exercise a few times each day and it’s super easy. I’d say it took me about 10 days to two weeks to get used to the chair, particularly as my muscles and posture started to adjust. But now I can sit and I don’t have any pain while sitting and only mild stiffness (no pain) after getting up. Looking back to how difficult sitting was before this chair and now, I am now ready to #sharemychair. I couldn’t be happier. Also, there was a problem with the saddle section when it arrived. It had too much padding at the top portion and rubbed against the chair, restricting motion. Customer Service sent me a new saddle section (no charge and didn’t need to return the defective saddle) and then the chair worked as expected.

I admittedly was very dubious about the Backstrong when I first heard about it from my chiropractor, who (disclosure) is also a friend of the chair’s inventor. I mean, a rocking bucket for the seat …. REALLY? We would discuss it the few times I went in to deal with some ache or pain, most if not all caused by the amount of time I spend sitting. I have spondylolisthesis and, as a writer who also runs a small research business, I sit much of the day and focus. That is NOT a good combo, which is why ergonomics and back support are VERY important to me. Over the years, I have spent thousands on chairs. For at least 10 years my chair was the Humanscale Freedom Chair. But I always complained it was too hard, especially at my tailbone and lower spine. Then, after doing an enormous amount of research and test-sitting, I switched to the Herman Miller Embody. The Embody’s concept (in theory, at least) seemed to make sense since it uses tiny spring-like pixels that supposedly release pressure as your body moves. That was my chair for at least the last six years. But I still had uncomfortable pressure in my tailbone and lower spine. And I would be stiff when I got up after hours of sitting. I’m 68, so I simply figured that was to be expected. But still… I hated the stiffness of my spine, especially since I regularly exercise and do stretching exercises. With both the Freedom Chair and the Embody, I also always grumbled that neither would tilt forward or do something so I wouldn’t slouch as I would focus on writing. Then, about a year after my chiropractor first told me about it – after feeling the sitting was really starting to take a toll – I took the plunge. The Backstrong was on sale for Black Friday and was priced at about half the price of Embody with a money-back guarantee and a long trial period. I had ZERO to lose. Verdict: Let’s just say the Embody is now in the garage and will likely be sold or donated. The silly bucket on the Backstrong isn’t so silly, after all. For the first time in years, I can feel my vertebrate move (while I'm sitting, no less), at times like I’m having a minor adjustment. The REAL secret, I think, is that there is no chair – just air – where your tailbone is. That results in zero pressure. Some people have complained that it’s too hard. Well, it isn’t soft. But the benefit of that is that you are forced to stand every now and then. Let’s face it, there is no perfect chair; they ALL have tradeoffs. The Backstrong is closer to their claim of slouch proof WHILE YOU ARE WRITING than any chair I have seen or tried. This is a serious task chair with the added benefit of being able to rock your pelvis as you sit, so your lower spine doesn’t get stuck. (Think of the rocking pelvis exercises you might do while on your back.) The best news, I’m no longer stiff when I stand after hours of sitting. Certain pains have disappeared or have been minimized. My only complaint about the chair is the quality. The first chair they sent had a pretty bad squeak. That was immediately handled by the fantastic Sandra in customer relations. I have no idea who she is, but she deserves a raise. I also think the casters that come with the chair are too slick for hard flooring. I know that mine was. Solution: I replaced them with the wood-floor casters that I had ordered with my Embody. All in all, in my case this chair appears to REALLY be what the doctor ordered!
