In my opinion beds shoud be removable and avaliable in shops just like other furniture. Thanks to this solution we could hang something on the wall behind the bed. The same problem is with lamps and laterns. Permanent decoration is OK only in case of specific, unique houses like the one on Gray Beach or Hare's Den. In cities I would leave blank walls and no beds, to make everything customable.
Need more bed kits? It's a great option to add it into a Tibia Store.
I could add that some graphics of objects, like areca palm, trees etc. are cutted by wall graphic. Because of this I don't use Iron Crown in my house.
