Review: Lower Back Posture Correction and Support - Hey folks, Just wanted to leave an honest review here. I've had lower back midback and lower back problems for a few years now. The last six months have been bad, with relief from sciatica only coming to fruition within the last month and a half. I've never used this while my sciatica was at it's worst. Relief came with chiropractic help (for me), standing all day, and constantly working on good posture (before Curble). My Chiropractor would always remind me to keep keep my correct posture at the end of my back adjustments. He would always (gently) put press his knee into my lower back and pull my shoulders and their blades back, and he would have me sit there for five minutes to get used to feeling the curve and the arch. This chair does just that, it serves as a constant reminder to keep good posture. I've read reviews from some people that this made their lower back pain and sciatica worse...Allow me to reiterate: If you have bad sciatica, or Piriformis, you might not be able to sit or lean comfortably in any direction. If your sciatica is bad enough, just keeping correct posture might act as a 'stretch' and hurt. I say this because, intrinsically: This seat will force you into a proper posture. Please note: Some people will probably instinctually lean back in this chair, using their lower back muscles to counter the resistance of the chair that forces good posture: DO NOT lean back. This chair's resistance is meant to keep you from leaning back, and if you lean back far enough in this chair: you'll suffer the consequences of bad posture.. I've also read that some people didn't like the bucket like seat. I've experimented with putting my posterior into it all the way, and then just sitting on it as normal. When your cheeks sit evenly on the pads, and you don't try to shove your butt all the way back, it works best. The tops of the chair apply pressure to your towards your mid-lower-thoracic region, and this allows for reminder to keep your lower back curved and to exercise the muscles that keep the lower back curved. I have never had back pain after using this seat. This is a durable product, and the plastic (perhaps a composite) will last for years. It can be brought to baseball games, or race tracks, and can be used to make sitting on the floor or concrete much easy. The thing about sciatica is, sitting on soft surfaces is terrible...Curble allows you to keep good posture while sitting on the couch, the bed, the floor, on concrete, on chairs, on benches, on stools, in car seats with no lumbar support, et al. I LOVE this product. Even if you don't have back problems, I would highly recommend this product to keep good lower back posture...You've never had lower back pain, until you start searching for easy, quick, and painless ways to commit suicide (b/c living with the pain can be unbearable). If you are in the midst of terrible sciatica, sitting might be very painful for you and I recommend standing and working on posture for weeks. If you sit, make sure you are conscious of keeping the curve in your lower back and sit on the edge of the couch (If you don't have this product). Bad sciatica and Piriformis make the muscles tight, and stretching them (even the act of sitting in correct posture) can make your pain worse...Curble is a preventative measure and should not be used as means to 'recline' or 'lounge'. It's for correcting posture. Once your Sciatica or Piriformis (or both) become bearable so that you can sit for 10 minutes, I would recommend this product. If you can sit for 10 minutes, get this product right away. If you can't sit for more than 10 minutes, you need professional help and a good chiropractor. When standing becomes too exhausting, take a break in this chair and feel the benefits of good posture. Great product. Make sure you use it correctly. It's not a rocking chair, it's and you're probably not meant to shove your 'posterior' or butt all the way back. Sit in it normally, and the backs of the chair will do the rest for you. If you sit in it and feel no pressure on your lower back, scoot your butt back a little. Thanks for reading, hope it clarified, hope it helps.
Review: Great for folks with a flat rear! - I got this to help alleviate pain and pressure on my tailbone from having a flat rear with sciatica and displaced discs in my spine. It has been amazing so far. Here is my honest review: I have a flat butt so that causes me to sit on my tailbone quite often, exacerbating my back issues. And at almost 300 pounds, that’s a lot of weight for my coccyx to bear! Enter the Curble. This brace pushes into my lower back, which in turn, shifts my rear into proper sitting position so it takes the pressure off my coccyx and relieving pain. I’ve been able to sit for much longer periods of time thanks to the curble. I’ve tried it on my office chair, my bed and my wheelchair and it has helped me in any spot. The provided cushion isn’t as supportive as I’d like it to be but that’s a very minor gripe. It fits well in almost any chair and hasn’t slipped or shifted out of place. I will say that I don’t recommend sitting in it with silky/satin clothing on as that can cause you to slide out of the Curble but just be careful when getting in and out of it and that shouldn’t be an issue. This thing works great and I highly recommend it for anyone who has to sit for long periods of time, especially if you have a flat rear like me. Thanks!

### ⭐⭐⭐⭐ great concept
*by R***Y on December 19, 2024*

I like it when I first sit down. You quickly realize how awful your posture is when doing desk work. It’s made really well and you don’t have to put it together. So the value is good. I believe it would provide good support and help pain levels. However, you have to place it a couple of inches from the back of the chair. Then sit down. It feels great at first but mine is constantly moving back against the chair and it is very uncomfortable. I am not using mine currently. I also don’t know if this is happening bc I’m plus size. 180 lbs and a size 16. I am going to try to look into it more so I can reap the rewards others have.
