I'm not sure what the clip-top type is. But the first time I assembled it, I added the doors after it was upright and leveled. Without the doors, the walls still shift left and right, they are not secured tight enough at the base to not move, even with the top base connected. There's definitely less of the shift with the top on but it still feels loose at the base connection. Despite tightening the bolt the farthest I can, the side walls still shift. It did come with brackets to fasten to the wall and I think those could solve the problem, except the walls in my home are weak and it is advised by building management not to drill any holes or hang heavy objects on them so I'm on the fence about that and have it standing on it's own right now. I have to move it into another room later on anyhow once space is made available. If only I had a video recorder, I can show the shifting, but all I have now is a before and after in the photos above. It looks like the doors are attached right. If I shift it to the left as much as I can, everything is aligned as it was when I assembled it lying on the ground. Only when I let go and the weight/gravity pulls it over to the right, everything is misaligned. I might just have to fix it onto the wall, but I was wondering if there was a way around it.
