curble Grand (Extra Wide&Sturdy) 2PACK – Ergonomic Chair Back Support, Lumbar Support for Good Posture Correction and Back Pain Relief, Perfect for Office Chair and Work from Home, Patented(2P Black)

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 lowerback 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.

Holds my bum like I’m sitting in a Giant’s very large, benevolent, and comfy hands. It doesn’t feel like a chair or seat. It feels like you’re being whatever the sitting version of swaddled is. I love my curbie. Her name is Kirby in my home. I have scoliosis, cervical stenosis, and the fun Gumby disorder where you lack collagen and your lackings make you bendy and built like a noodle. As you can imagine, being a noodle can be tiring and I need a little fricking support. She is perfect for this. Use on the floor, in your car, on your bed so you dont watch tv like a capital letter “C”. I actually noticed my posture improving after weeks of use.

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.

Why did you pick this product vs others?:It is pricey but it is definitely worth it. Sufficient lumbar support for people like me with lower back issues. Recommended it to my colleagues and they loved it too.

This thing seems to basically be a “trainer” to remind you to sit in an intrinsically unrelaxed sort of upright fashion instead of leaning back comfortably.I’ve only had it a couple of days, and so far I would say it works as a “trainer” if you use it in a certain way, and with certain limitations.1) If you sit with your feet down, it is fairly easy to keep your back in the position it wants, and the pressure on you is not obnoxious once you get used to it and adjust your posture. I assume this is the way they have in mind that you should sit.2) If you sit this way, it’s just mildly irritating, and you can get used to it and sit for long times. However, the “pads” on the bottom are minimalist, and they are OK if you are wearing a bathrobe or something equivalent, but if you have on pants with anything in the rear pockets (keys, for example) your butt will go numb after a while…at least, mine does. Likewise the “pads” on the top are minimalist. A downside is that to keep the lower back the way it wants, the upper back is leaned forward, in other words, your lower back tends to be straight and your upper back hunched forward, not quite ideal.BUT: If you sit with your legs out, that is, feet elevated to the level of your hips, as I am supposed to do due to varicose veins, it’s like having two giant guys behind you ramming their fists into your kidneys. You can tense yourself up and lean forward, which will reduce the pressure a bit, but I still have questions about whether having so much force on the soft meat over your kidneys is a good idea. If I skooch down some, and slide my hips forward some, I can get the top of the back “pads” on my bottom ribs, which is an improvement, although it induces spasms in the muscles under the ribs.Bottom line is that the idea has some merit but requires a certain type of sitting to work. In my opinion a) the back should come up higher (at least shoulder blade height) and be curved the way your upper back should curve, so you could lean back in it comfortably, b) the “pads” should be thicker and softer and c) the “pads” should engage the spine of the lower back like a normal “lumbar” pillow instead of torturing the kidneys.I’m going to try it longer, see if my opinion gets more positive, but first impressions are that it is useful though imperfect if you can sit with your legs hanging down. It’s next to useless if you can’t or shouldn’t. Since you do have to sit that way in the car, that could be a place it’s useful. To me, the photos of someone lounging with it in a couch are highly misleading. Unless their waist is short enough to get the “pads” on their ribs. [I am 5ft 10inches and about 160 lbs. The width is correct for me, just FYI. I could probably be two inches wider and still have it work OK that way.]I wanted it since sometimes I have back pain in my soft easy chair. Sitting with this thing with my feet down does seem (probably) to help that a little, at the expense of the veins. But I think overall the right arrangement of lumbar and seat cushion pillows works better for me in general.Your mileage may vary. A lot of folks seem to love it.

Excellent product has helped my back tremendously as I have a L4,L5 & S1 bulging disc. Keeps me upright so I don’t slouch! Highly recommend this product 👍🏻
