The chair was easy to assemble and comfortable but the instructions do not explain how to secure the castors. I consider this a safety issue. They slide in where the instructions indicate but they don't stick. I am going to call the number provided to see if they can explain. Otherwise I guess I will have to use some type of super glue. I would not buy it again. I'm 5'1" so I need the additional height the castors provide. If a potential buyer is not concerned about the castors then it's a good value. I am disappointed because if not for that one problem it would be a good chair . . .but my cats like the chair!
