curble Grand– Extra Wide Ergonomic Seat Support, Sit Straighter Without Effort, Passive Posture Trainer for Office, Home & Car (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 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.

I purchased on Amazon and still use an excellent lower back padded full back rest that straps on the upright back if a standard chair (see my rare prior reviews)--but this sturdy Currie wide head shell provides PERFECT lower back pain relief on its own, ONLY WHEN you adjust your buttock placement until most comfortable--by using each hand to grasp behind you the top of it to adjust your buttocks to locate your unique personal maximum relief, and readjust that way whenever last position becomes less comfortable. PS: I find it especially comfortable when sat on a cushion or mattress with a pillow behind my back to cushion its firm upright back support. Hope that helps!

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.

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!

So when I ordered this item, I was unsure since had never seen anything like it before. My family laughed at first when it arrived, but no one is laughing now. It works!! I have degenerative disk disease problems in my lower back and always need some type of lumbar support when I sit. This is a very well made solid unit that I can easily pick up and use in different chairs...so completely mobile and light weight. I'm using it in my kitchen chair, my sewing chair, patio chair, etc. Easy to transport around and it saves my back from all the stiffness and soreness I would have otherwise with all the comfort I need for lumbar support. I only wish it could fold it in half to take with me on the go, but then that would probably compromise it's effectiveness since It's one solid piece that fits just right like a glove. I love it! I have the cover too which makes completes unit perfectly with added cushioning.

This product had so much promise; but it fell short. I really like the idea and would carry this everywhere with me because my back ends up in knots at restaurants, in waiting rooms, classrooms, and other places where I do not have my own chair with me. However, it needs a few fixes. For background: 1. I have never been able to use lumbar support, because those supports lack support of the lower thoracic region and do nothing to correct the backward slant of most chair cushions, leaving the user leaning back into it, thus causing poor thoracic posture. 2. Full "ergonomic" cushions seem to be designed for 10-year olds or people without a behind, thus press into your pelvis region and behind (too low) and do nothing more than push you further away from the back cushion and do nothing to correct the backward slant of most chair cushions, again leaving the user with poor thoracic posture. 3. To make matters worse, even common task chairs and office chairs have these "too low" ergonomics that seem to have left out the fact that people do have pelvis regions and behinds that need space underneath the lumbar, so the ergonomics are all wrong. 4. I am between the average heights of a woman and a man, so average. 5. I currently sit all day and comfortably use an “old school” very aged and tattered task chair with no arms that is at a right angle with the seat back high enough to start just above my behind and end in the lower thoracic region. I wish I could take it everywhere with me. I wish I could find a new one just like it too! Even the same brand new ones cut corners now and have a lower seat back that jabs me in the behind/pelvis, thus has no support. I was super excited to find the Curble, which appeared to correct this issue in the images on the Amazon listing. Here are my thoughts after trying it: 1. When placed on a table or chair that has a flat seat cushion with no angle, it appears the Curble would support the back perfectly. However, when you sit it the entire Curble is curved, so it tips forward towards your front causing the back portion to tip forward too much and jab the user in the back. Instead of providing perfect upright posture I found I couldn’t sit all the way in the Curble and the top of the seat back without the cushion jabbed me painfully in the ribs because it was angled forward instead of upright. 2. Simply put, the user cannot sit properly at a 90-degree right angle. The Curble is too tight to fit into properly. It is an acute angle (less than 90 degrees). 3. Then I tried it on a seat cushion in a chair that is slightly angled backward, and it was jabbing me painfully in the back. I kept trying to push it back away from my lower rib and move my behind into the curved area with no success. Ultimately, it dislodged a rib and now the rib is stuck. It’s been 3 days, and I am still having rib pain on the right side that will require chiropractic care. 4. Thinking it might be better on a sofa or side chair that is soft and angled backward I gave that a try. While it did keep me more upright back wise, the whole Curble rolled backward into the chair and I had a hard time getting up out of the chair because I was crammed into the Curble at less than 90 degrees, rolled backward, and had the angle of the sofa to contend with. 5. Examining the Curble on a flat table surface, it looks like perfect support. The issue is that when you sit in it the whole unit tips forward. This can be evidenced by simply pressing on the front of the Curble as though you were sitting in it and watching it tip forward into a poor posture position as shown in the image I posted. Instead of upright, the back of the Curble slants forward. 6. I placed a wedge under the front of the seat which brought the back portion of the Curble to an upright position that would support the back, but it left the seat bottom portion angled back, which is hard to get in and out of and not good for the back. 7. I have a longer middle, so the back of the chair is a bit too low. It needs at least another inch in height, preferably 1-1/2 – 2” to fully support my back. 8. The padding on the Curble is minimal. It needs padding covering the edges on the back support portion, so they don’t jab into you. 9. The plastic is pretty hard and unforgiving, making it a solid item. I thought, for the price, that the plastic was sold. 10. The price, overall, I felt was high. Yes, the plastic is sturdy & solid. But, the padding lacks. Overall, I think the Curble would be best off with a flat bottom and the back portion sat a right angle to it with more padding covering the edges. Better yet would be if the flat bottom was adjustable so that it can be used on chairs with various seat cushion angles without rolling over. Then, it would be perfect.

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.

I learned of this device from a family member - it's been awesome at providing proper support for my lower back. I sit in a chair 10+ hours a day for work so always have had posture/back issues from all the years. I've had to perform many PT/stretches throughout the day to manage my back pain symptoms. Since getting the curble, I haven't had to perform exercises as much as before. We'll see how much the curble helps in the long term but it's definitely helping with my lower back pain since receiving it. You will occasionally need to take breaks from sitting on it as it does place higher pressure on certain parts of your back and thighs as it forces you into a better posture. Build-wise, it seems well designed and very durable. Overall, I'm glad to have gotten this device and happy with results thus far.

Quizá es un buen producto pero no para mí, me causaba dolor de coxis

actually works! I was hesitant but this has made a HUGE difference in supporting lumbar and back and posture. I can’t believe how long I was using little sausage pillows that didn’t really help. I thought it might be weird / uncomfortable to sit on but I don’t even notice. highly recommend.

For a mom who has just given birth, it really does provide helpful support for the lower-back muscles and offers noticeable comfort.

This is extremely not comfortable. It put a lot of pressure behind the knee. Hope I can return it
