SMUG Office Computer Gaming Desk Chair

At first, I was ecstatic about this chair. It was easy to assemble, looked great, was comfy, and seemed durable. For $100, it was everything I wanted in a chair. However, slowly over time, problems began to arise. In order, these are the things that are currently wrong with the chair. Although it may seem nitpicky, it really does add up.1. The chair isn't completely stable no matter how loosely or tightly you adjust it. If you put pressure on any edge, the chair wiggles. This is the least annoying of the 3 problems.2. When you swivel/rotate while on the chair, a high pitch squeaking noise appears.3. Most annoyingly and recent, whenever I sit on the chair from a standing position, the height of the chair goes all the way down. Once I'm on, if I adjust the height and don't put too much weight, it'll stay. However, if I sit from a standing position, it goes down.Note: I am 200 lbs, so I am on the heavier side. I'm sure that the problems I listed could partially be attributed to my weight. Even still, my weight is under the maximum weight so these things should not be an issue.These small issues add up to a less than ideal experience. I am a little disappointed.
