The lounger wasn't accepted because it's too narrow, stiff, has a thin cushion, and an uncomfortable shape. However, it sticks really well to the window. Only suitable for very small cats.
Cleaned and dried the window before attaching it. In the first few weeks, it stuck well to the window. My cat loved it, but unfortunately it keeps sliding off the window now and I have to get rid of it.
Not enough suction power.
