So we live in a smaller house and space is lacking! So in our living room we have a sofa, chair and loveseat, along with a coffee table and 2 end tables. In order to make some space I purchased a 2×8 pine board from my local harware store for about $7. I didnt need to cut it because of the size of my couch. I stained it the color I wanted, which was a nice black/brown. I then measured on my wall where the studs were and screwed in 2 L shaped brackets. Then put my shelf ontop of the brackets and screwed it together.
So in the end I gained a lot of space because I have gotten rid of my 2 end tables and I am now using my shelf to hold my phone, remotes, and lamps! And with small children in the house it makes up for toy space!!
