Assuming you would like a room fit for royalty, here are a few furniture and accessory ideas for a Beauty and the Beast themed room:
A grand four-poster bed with billowing curtains would be the perfect centerpiece for the room. To add a touch of whimsy, you could hang a chandelier above the bed. For the walls, you could wallpaper with a floral or damask pattern in hues of blue and yellow. Add gilded mirrors and sconces for a touch of luxury. To bring the outdoors in, place fresh flowers in vases around the room. And of course, no Beauty and the Beast room would be complete without a rose in a glass dome!
