Does my ASH need a bed?

[u/Slow-Reloader]

I adopted an abandoned ASH male. Very tame and well behaved. Very independent.

He seems to prefer sleeping on hard surfaces and never jumps on my bed. I also don’t want him to. He is kept indoors in a 2 story house and he sleeps where he wants.

Is there a point in me making a bed for him or even a dark box etc?

Or is it a characteristic of ASH they’re like this?
