Pretty easy to set up.  As of now, only 1 of our 2 cats has laid on this, and not for very long.  The sun was coming in the window and that is possibly why she didn't stay on it very long.  When the weather gets colder here in Colorado, they may both be fighting over it.  Ha-Ha.  It feels very soft / padded, which is nice.  I like that the cover comes off & is washable.
