These 'things' are part of a set design, or 'dressing' a room. Me, I like a comfy bed, a warm duvet and comfortable squashy pillows. I do not need extra pillows/cushions/bedrunner on my bed, that I then have to remove before I get into bed at night, and put somewhere else, other than the floor - but probably the floor. My sister likes her bedroom to look like a photo from a magazine, with all of the extra cushions, bed coverings folded back, and a visually appealing bedside cupboard etc, etc.
'Dressing' a room for sale, or viewing, is completely different to a lived in room, whether it is a kitchen, living room, or a bedroom. To me, it is trying to make your house look like the 'lifestyle' magazines, and is a million miles away from someone with a busy family, work and a life to live.
