It’s funny what rabbits find to be comfortable resting places. I used to try to make/buy nice soft beds for my rabbits, but eventually determined from their reactions that these beds were apparently too wrinkly and weren’t saturated enough with rabbit urine (quickly remedied by them). Instead, I discovered that rabbits (at least my own) prefer hard areas- like plastic food mats, hearths, vents, and as pictured below, entertainment stands.
