I've stopped trying with the cat beds at this point... She'll sleep on it for like a week then never touch it again her favorite place to sleep now is any freshly opened shipping box lol
For flat beds like the one in the picture they should be up high.
My cat has one on top of a bookcase in my office that is her go to spot (seriously the nice cat tree I got her is only used for scratching and as a platform to get to the bed).
Enclosed beds usually work better on the ground as it allows them to feel safe.
