curbleWider(Standard Wide) – Ergonomic Lower Back Support, Lumbar Support Back Posture Corrector for Low Back Pain Relief, Perfect for Home Office Desk Chair, and Floor Seat, Patented (Black)

These are literally the best back supports I've ever used. They fit your form and support each area perfectly.

Love it

Not sure what the 'wider' part means. I'm not fat and my butt goes off the sides. Love the support of it, I've tried hundreds of dollars of seats, this works bet so far

The chair is comfortable and helps ease the pain in my lower back

I have tried this (both sizes) to help with my sitting properly and ease lower back issues. But it doesn't help, and actually makes it much worse. It also created other issues. Like hip/sciatica issues. I have kept these too long to return. So donating them. Maybe someone else will like them. Disappointed

I tried this wider version at my mom's when I visited her. It helps to reduce my back pain, so I bought the Grand for myself. Wherever I go, I carry my own seat that's uncomfortable, so I bought this Wider on last prime day to keep it on car not to carry out from home office. Hmm. Maybe I am used with the Grand, actually my size should be fit for this Wider, but I feel uncomfortable . The sacrum is too closed on chair. I may return and repurchase the Wider. I am 5.3 and 119 lbs.

I liked it at first, but now my bum gets numb. I can only use it for one hour at a time.

the first curble chair i purchased was the adult and was too large. so i tried the teenager cuz i'm 5'4" and 110 lbs although decades away from a teenager. I love it. i use it in the car and while sitting to eat. One thing i've noticed when sitting at a table is i don't feel any inclination to cross my legs which in the past was leaving me "unbalanced" once i stood up. but not with this chair...instead i feel the more natural desire to simply cross my ankles while sitting and i'm quite comfortable and, best of all, just as comfortable when i stand up to walk!! i do look forward to how i feel after driving for an hour's time. that'll be interesting.
