Furnishings are the most prominent part of décor in a room. When the decoration under discussion is that of your bedroom, then the styles need to be special and in accordance to your taste and preference.
Designs for beds can vary from cozy to comfy, antique to modern etc. Canopies on poster beds give a very royal look and they are hardly out of fashion. Wrought iron beds give a very sleek look and light wood is best for the summers. Go for downy pillows and a lot of cushions to add volume to the bed.
The best items to relax on are the comforters in your room. Make sure they are nice, big and comfy. Leather comforters and bean bags are a must have in a bedroom. You can always go for a three seater to accommodate you at full length and a one seater with a foot rest for reading and other purposes. With all these items your lovely room is ready to use.
