Same. Our cats prefer cardboard boxes cut down to be about 3” walls vs a commercial cat bed.

Ours just sleep on sofa and beds

Try putting it in an elevated position. Most cats will like and use it more, even if it’s only 2 or 3 feet off the ground.

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.
