## Description

Product Description

Review: No more back pain and aches - Let me say I have struggled with low back pain for years. When I sit in my office chair I always for some reason sit toward the front so my lower back doesn't have support. I decided to get the Curble. I originally ordered the Wider Curble and honestly it was very small that my behind didn't even fit on it. I sent it back and got the Grande Curble. It fits perfectly and has so much support on lower back. It has a little bit of cushion on the seat and back. It is made out of some type of heavy plastic but seems durable. I weigh 165 and am 5'8 and the height of the back support hits me mid back. It is very light weight so it can easily move to a different chair with you or take in the car. Even if you are a smaller person I would go ahead and get the Grande to have a little extra room. The shape of it makes your behind fit in it a certain way where you get the most support.
Review: Top-Quality Product for Great Posture Support! - This item was purchased to provide the gentle posture correction that I need (back support). I ordered a set of two in addition to covers. When it arrived I was totally impressed with the TOP QUALITY materials used to create this innovative but effective “seat” as well as the covers. The design is GENIUS! I am using one “chair” on my expensive sofa (the back of which slants at an uncomfortable angle backward, creating a backache for me all night); the other one will be used to eliminate the back pain that I experience in the seats of most vehicles. So glad I discovered this product!

## Features

- SIT BETTER INSTANTLY — NO STRAPS, NO ADJUSTMENTS: Just sit down and feel your body naturally guided into a more upright position. Unlike bulky cushions that require constant readjustment, the Curble Grand works passively to support your spine the moment you sit.
- DESIGNED TO SUPPORT, NOT FORCE: Unlike rigid posture braces that aggressively push your back, Curble encourages gentle, natural alignment. Proudly Made in Korea, it has passed rigorous KOTITI and SGS safety tests, ensuring it is completely free of VOCs in the PU foam and harmful substances in the fabric.
- BALANCED FIRMNESS & EXTREME DURABILITY: Engineered to provide structural support, it boasts a maximum compressive load of 1,190 lbs (540 kg). (Note: Bouncing or forcefully pushing back may exceed this limit). It may take a few days for your body to adapt. Start with short 30-minute sessions
- WORKS ANYWHERE YOU SIT: Lightweight and highly portable, it transforms any seat into an ergonomic workstation. Perfect for office chairs, couches, car seats, gaming chairs, or even sitting directly on the floor.
- A MICRO-HABIT BUILDER: Use it consistently at the office, home, or in your car so you never break your healthy sitting habits. Consistency is key to building better posture without even thinking about it.

## 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.

### ⭐⭐⭐⭐⭐ Great for ergonomics and posture
*by E***Y on 18 February 2025*

This can turn any chair into an extremely comfortable chair. It is also great in the absence of a chair just straight on the floor because of the additional lumber support that it provides. This size is vastly superior to other sizes as the split design allows for a more custom fit against your back and allows you to shift your weight. The cushions are removable for washing and / or cleaning.
