I've tried a few different beds with my kitty and she just doesn't like them. She prefers to sleep in her own sought out spots....on top of a dresser, the end of the couch or bed, a basket of clean laundry, the book I'm reading....
The only way I've gotten her to sleep on them was to put a piece of clothing/towel on part of it that she really likes. When we take her to the kennel, we put her towel in there so she has something familiar, so we tried using it for the bed, too, and it worked for a little bit. Eventually she got bored with it, though, just like she does with every other sleeping spot, so it wasn't a lasting thing for us.
