I have a fussy senior dog, and she loves this bed!  I DID use the cover from her old bed and placed it on top for the first 3 nights as it had her scent was on it. So, she slept on it from day one. It has memory foam beads vs a flat piece of memory foam, so it contours to her body.  Some beds, don't. Great value. Majority of dog beds, elsewhere, are far more expensive.
