After I searched and read all the posts on how to hang inside I decided to go to Home Depot to look around… I found heavy duty lags by Spax and some surface mount 1200lbs D rings.
I mounted them to studs in two opposing walls and slept like a baby all night! I wanted to take some pics with me in it but I was using my iPhone. You can see it’s hanging directly over my sofa (just in case it didn’t hold!) and Koda underneath.
