We were temporarily using this sofa indoors while waiting for the movers to deliver our belongings to our home. I almost wanted to keep it inside because it is a beautiful, casual piece. It wasn't difficult to assemble but would have been easier if our tools had arrived and been on hand. Allen wrenches consume more time and effort. 
We've now been enjoying this sofa outdoors - it is comfortable and looks amazing - a quality piece. I bought covers, though, to protect the ivory cushions from droppings from both the tree overhead and birds. Very happy with it!
