Hello. I have used them in long large bedrooms to divide space. They have served there purpose and did work. But keep in mind, they are not fixed and can move and may be safety issues depending on the age of people living in the house. Before we sold the house and relocated, we changed it back to the original state. However I have never used them for common living areas. In those areas I have made defined areas with furniture, carpets or a combination.
I hope this helps and if you need to ask more questions, please feel free to contact me at 813-545-5711.
