These types of room decors looks cool. It is highly recommended if you have a little space on your room and would want to make all your stuffs to be there but still need to be organized and spacious. I think having bright paint colors for your room makes it look spacious, cozy and comfortable. I know I am not an interior designer, that's just an observation though. I like the designs from the second and fifth photo, so modern and yet cozy. I would want to make my room look like one of these. LOL.
