I bet I'm not alone

Mine's called the floor

And instead of cleaning it off to sit you just precariously balance on all the junk

It's the futon for me

Mine is 'the house'

Yep, just chucked my clothes on it and the extra pillows I have on my bed, my headphones, my iPad.

mines a shelf in my closet

That's called my closet.

I have two beds in my room. I just use the other bed.
