Hola! This is a good buy. Out of the box, base was sort of dusty so I took it to the backyard and washed it off. I bought the Mophorn replacement base and mechanism to repair a 1 yr. old Ficmax Gaming Chair which wasn't cheap and by far, the worse chair I ever bought. It didn't swivel, it wobbled, from left to right. Cushion broke down in 3 months, terribly hard to lean back in and a bad caster cracked the base. There was more wrong but we'll leave it that.It took me a few minutes to install the Mophorn base kit and it was an immediate fix. Coasts easier, rolls good on carpet, has a taller lift, swivel is agile and leans back easily. I just got a cushion for it and it's comfortable. It's only been 5 days so I'll update this in a few months. Right now, it the best my chairs' ever been.
