This product is very hard and good.

I bought this and requested the companion gas lift but it has been 3 weeks with no response . I can't use this base and have a filling I should have just bought a new chair instead of trying to fix my old Techni

Amazing, simple and easy to put on

Techni Metal Base

My previous base was uneven and the company refused to replace it. It even ruined all of my wheels (the metal peg was bending the plastic out of place and the wheels were falling off as I sat in the chair when I moved), which the company did replace recently. Because of the wheels issue, I removed the wheels and the base sat directly on the floor. I knew new wheels would be ruined again so I purchased this base since I couldn't use the old base and the chair was rendered useless without a new one. So far everything seems good and the overall experience is much better than the base that comes with the chair. For reference I have the TS51 Black GG Series Gaming Chair.
