PS3 Slim Stand Description

In order to use the console vertically, you should have a vertical PS3 slim stand for it. As long as the PS3 Slim stands against a solid surface, you are free to keep it vertical.

The official PS3 Slim Stand is the all-new PlayStation 3 Slim’s stand. It works by laying flat on whatever surface you deem fit, and then it holds your new gaming console upright.
We get the impression that it’ll do its job fairly well. Or, it’s just
the motivation you needed to craft one on your own and prove that you
were indeed born with a few DIY genes. [more PS3 Slim accessosries]
