Get some relief while strengthening your core!

Core-Tex Sit is a nice addition of home-exercising equipment for anyone looking to improve their posture and alleviate back pain. It forces you to stay balanced while sitting, which helps keep muscles engaged and reduces the strain that static sitting often causes.

I've personally noticed an improvement in my posture and reduced tension in my lower back, you just gotta stay consistent!

Riders - get this to help improve your seat & stability!

I saw the core-Tex sit on instagram being used by a 5* rider and thought I’d give it a try. It has been the easiest tool to add to my toolkit and implement in my daily routine because it’s so simple, yet so effective! As a rider, my core strength and stability is extremely important. Changing disciplines from hunter to eventing, I was struggling to really find my seat. The core-tex sit has helped me really sit in the saddle and use my body correctly. I’ve had lots of close calls, but it’s much harder to get me out of the saddle now while jumping! My flat work/dressage has also dramatically improved. Highly recommend to everyone, but especially equestrians!

The Core-Tex Sit perfectly fits my needs and expectations (Wax On - Wax Off)!

I bought one, then another, and now I'm about to buy yet another one!

The reason is simple: a friend tried it for a few minutes and said, "Thank you, I need this to help me with my back!"

At 76, almost 77, we were both stunned when I managed to pull off 12 Asian Squats, something I couldn't dream of doing before using the Core-Tex Sit. I use it as intended while watching TV, and I had another one on a music stand by my rowing machine for pre- and post-workout sessions, which now needs replacing. That's my story and I'm sticking to it.

Interesting

I appreciate the idea, but it’s not conducive to most chairs, gets stuck into deeper cushions (like couches), and it hurts to use (because of the materials, not because the motion or activity is painful—just sitting on it is inherently and unfortunately not cushioned enough). Great concept but needs work before I could recommend.

Thank you for taking the time to offer your feedback, Tessa. We agree that Core-Tex Sit is not meant for deeper cushions due to the fact that it will sink into the cushion because of the users bodyweight causing the surrounding cushioning to limit motion. That is why we recommend flatter firmer surfaces. We understand the firmness did not agree with you as well. We hope you understand that the shape of Core-Tex Sit is designed to be maintained with that convex shape, which would be lost with too much padding. That is also why Core-Tex Sit is not a chair replacement, but meant to be used intermittently throughout the day. We appreciate your input and hope it is of value to other potential users.
