## Customer Reviews

### ⭐⭐⭐⭐⭐ Get these. Be safe.
*by  on Reviewed in the United States May 5, 2025*

The bases on 3 Vevor chairs, failed. Broke. Collapsed. We sought refunds and reached a claim. This base is exceptionally strong, and More importantly, it is one piece for each leg. I do not understand why and in what universe that it would make logical sense to injection mold, a chair base with four of the legs molded, but the fifth leg to be bolted on with a small piece of plastic inserted into the other one. . Easy to assemble. Installation was nice. The height is rate and handles a lot of the weight and it is zero noise.

### ⭐⭐⭐⭐⭐ Great replacement part for the cheap base originally provided with the chair
*by  on Reviewed in the United States February 3, 2026*

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.

### ⭐⭐⭐⭐⭐ Great Purchase
*by  on Reviewed in the United States October 30, 2025*

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.
