I need to find some cheap beds and mattresses for my lakehouse.  We used to have tenants living on the upper level and we used the basement but now we have the whole house to ourselves.  So there are 3 completely empty rooms that need your help!  No one is even going to "claim" the rooms because the house has 6 bedrooms and there are 4 of us, with my parents sharing one of the rooms.  So these would be guest rooms/whatever rooms.  I just hate to see a completely empty room so I figured maybe a bed and a night stand would make it better??? Any help on where to get cheap beds and how to improve the empty room problem is greatly appreciated!
