It is insanely uncomfortable

I bought this at a conference with high hopes and upon sitting on it for longer than 5 minutes, It was putting pressure entirely on one point in the middle. The material used on it is not forgiving and it was actually making me numb after a short time on it like I was sitting on a skinny bicycle seat. I think the concept is great, but it's really uncomfortable and I have barely used it because of that.

Hi Andrew,

Thank you for taking the time to share your thoughts on Core-Tex Sit. We are obviously disappointed to see that Core-Tex Sit has not met your expectations. If I may just clarify, Core-Tex Sit is not meant as a long-term replacement for your sitting surface. It is a tool to introduce a variable environment intermittently throughout the day and/or an environment to perform purposeful exercises on for a finite amount of time. The firmness of the surface is there to help the user center the “sit” bones on the surface. I personally use my Core-Tex Sit for about 30 minutes intervals while working and then return to my normal work chair.

If you have not seen this short “getting started” video, you may find it helpful. https://coretexfitness.com/blogs/core-tex-sit/getting-started-with-your-core-tex-sit

Please feel free to reach out to me personally if I can be of any further assistance with improving your experience.

Sincerely,

Perfect for Lumbopelvic mobility!

Core-Tex Sit provides my patients with the perfect amount of lumbopelvic
mobility that they have not been able to get with just an exercise ball.
It's easily moveable, lightweight and takes up very little space when not in
use. The unique motion creates a great environment for strength, mobility,
and stability that I am trying to achieve with lumbopelvic exercises while
in the clinic or for the patient at home.

Great product!

This is such an overall great product. I always have a lot of tightness in my lower back but felt so much relief when using the Core-Tex Sit because I was easily able to stretch those areas out. As another reviewer mentioned, I'm able to get those chiropractic "pops" which alleviate some of that discomfort. Because of it's size, it's also incredibly convenient and easily transportable.

It is also great for my fellow fidgeters. When I have to sit for long periods of time, the Core-Tex Sit allows me to wiggle around and get that uncomfortable feeling out without having to get up and walk around, which would disturb my work.

I would definitely recommend!

I don't leave home without it

I love the Core-Tex Sit. I have incorporated the Core-Tex Sit into my daily routine by bringing it with me to coffee shops and libraries where I do most of my work. I actually keep it in the trunk of my car so I have it where ever I go for work. It's a godsend! Elevating my tuberosities, and feels great on my back. The Core-Tex Sit moves with me and truly is an amazing product!
