'New chair'?

I have a favourite corner, when I'm indoors. It's warm, it's cosy, the light hits it at the right angle, and it smells right.

I like napping in that corner.
I like napping on the big, soft chair that's there.

The chair seemed to be different recently. The soft bit seems darker, it smells strange... but it's still in my favourite corner.

My human keeps doing something annoying though. Every time I'm asleep, he picks me up, moves me, and says something about 'not on the new chair'.

What is 'new chair'?
Why does he keep moving me?

Idiot human.
