Review: Great Purchase - It came quickly and undamaged. The Fits without issue on my chair, it makes the chair a lot higher than the older base which for me was a pleasant surprise. For someone who is over 6 ft tall like I am, the height is perfect, although my gf may complain that her feet swing off the ends now. Its very stable. doesn't rock at all, and once the gas canister is set, it doesn't shift any more. I'm completed pleased with this purchase.
Review: Great replacement part for the cheap base originally provided with the chair - I bought this chair base to replace the manufacturer's original base. The OEM base was not suited to upgraded skate wheel installation, and was failing to allow the chair to roll freely. The original plastic wheel sockets would bend and cause the chair to lean. This base is perfect for the application. All metal construction, especially the receiver ports for the wheel posts. Solid construction, assembles in 5 minutes, and provides the stability I was looking for with the better wheels. It does not come with wheels at all, so you'll have to provide your own. The kit does include the hardware and hex key to assemble the base if you don't already have these tools.

### ⭐⭐⭐⭐⭐ Works!
*by A***R on February 1, 2025*

Had a great gaming/ office desk chair- however after 3 years the base cracked literally in 1/2. The manufacturer did make it any longer- thus no parts. This was a PERFECT fit. Assembled with the 4 bolts given... not only stronger- and a bit wider spread for more stability! Highly recommend- but definitely check measurement to assure correct fitment.
