Do you also pair it with dim light? because my room uses 20 Watt and it's so bright. Unless I change to "yellow"-ish light and then it'll make me sleepy :D

Strange as it sounds, I still sleep on the floor at times when I am staying a hotel and the way I do it is just by covering it with the towels and those tapestry. I don't know but my back likes it more 🤣
