A black rug will make a space feel warmer and essentially, smaller. Ideal if you have an open-plan apartment or hardwood floors that feel cold and uncomfortable. Opt for a fluffy type if you're wanting extra cozy vibes or go for jute if you're needing something a little simpler. If you have a large living room (lucky) or a big bedroom (even luckier), then a dark-colored rug will make the space feel less sprawling.
