Our second generation Core-Tex Sit has a few updates that makes Core-Tex Sit even more convenient and accessible to larger users. 

1. We've added a lightweight cover to the bottom, which will allow you to use softer surfaces without compromising performance. 
2. We have decreased the flex of the top section, which also improves performance AND makes it available to users up to 300 lbs. 

If you already have a Core-Tex Sit first generation, we will have the bottom piece available on our site that you can add to your existing unit.
