## Customer Reviews

### ⭐⭐⭐⭐⭐ This is a well made product. But it needs 2 holes to secure to your chair base. Check first!
*by  on Reviewed in the United States June 9, 2022*

This is a well made product. Happy that I found it. But I now see that the L-arm that goes under the chair base needs 2 holes to secure to the base, but the office chair that I have only has 1 hole, so, it’s unfortunately not compatible. Do make sure you check before you buy.

### ⭐⭐⭐⭐ Works well for Secretlabs chairs
*by  on Reviewed in the United States December 21, 2022*

Will fit fine on Secretlabs chairs, at least the 2020 Omega but I'm fairly sure they're all similar. They sit slightly further out than the originals even if you screw them in as close as possible to the seat. The only thing that's an issue is that the 40 degree left and right tilt isn't locked in by anything, so if you put your elbow in the wrong place and put a little too much weight on it, it'll tilt on its own.

### ⭐⭐⭐⭐⭐ EXACT replacement for 2021 model GT Omega Pro series seats.
*by  on Reviewed in the United States September 24, 2025*

Direct replacement as used on GT Omega chair, it is identical, and if it will last as long as the original did before the PIVOT feature gave up it was a good deal.
