Patches just requires a pillow as something to lay on.
I haven't tried a bed with Luna yet.
Beauty on the other hand...we brought home food from Costco one night and the box we used to carry was flat and big (like one you would see with bulk fruits) and on the floor. Beauty plopped herself in it and started purring really loud. The following weekend I went out to the fabric store and got some fleece. Sewed together a pillow mattress and a pillow to put her but up against and she spends most of her days in the bed now!
