A cosy bedroom is important for teenagers. A room where they feel cocooned and secure, while studying, watching TV series or simply relaxing with friends. Pastel colours, loads of cushions on a bed and fairy lights are simple ways to bring that cosy feel to a bedroom. Keep it tidy but fun with practical storage (Ikea shelves) and fixing a simple rod between them and the wall with light white sheer curtains to hide clothes hanging. Add a square frame of black and white of day-to-day BFF pictures to give it that final personalised touch!
