Review: 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: 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.

## Questions & Answers

**Q: Does it work for big butt/high butt people?**
A: It depends on how big is but normally works.

**Q: let me get this straight -- i need the chair AND i need the cover? Whats the difference b/t sitting crosslegged, on top of a small cushion and this?**
A: The cover is not necessary but we recommend to who want a little more cushioning.
The difference b/t Curble Chair and a kneeling chair is that Curble Chair helps you to sit up straight by supporting your back while providing the comfort of your legs.

**Q: Where do find the size chart?**
A: Please refer to the video. Curble Grand is W16.5 x D12.7 x H13.6 inch which is a suitable size for adults. We also have other smaller models for petite, teenagers, and kids.

**Q: Where can I purchase replacement cushions and stops?  How much more cushion does the cover provide?  Thank you.**
A: We are working on the replacement cushion to launch it on Amazon within 2023.
We highly recommend the cover because you can use Curble Chair more comfortably since it covers all the edges of the Curble Chair and provide good ventilation with air mesh material.
