As someone who made millions (!!) by selling housing items let me give you still an advice - Be careful. Housing items don't sell as good or as fast as HQ food for example. Some items like windows sell better because people tend to use more of them instead of like your beds. I wish you best of luck with your selling procedure and I hope you will sell all you want. But keep that in mind Look up the sell history. If there hasn't been any major sells in beds then this probably won't rise in the future.
