This Victorian tree, described in the Seasons pages here, occupies one of my display lamps each Christmas. The rest of the setting varies somewhat, depending on my mood and the amount of time I want to spend in Christmas decorating.
One year I used the white sofa with only a few touches added to suggest Christmas.
For example, a few wrapped packages; one on the chair and others beside it on the floor.
A candle arrangement on the coffee table and a pale green silk throw on the sofa were enough to suggest the season that time.
