Our cozy corner is definitely our living room (where we also spend most of our time at)! We use a movable trolley from IKEA to move our projector around so that we can easily stow it away when not needed (the trolley also serves as extra storage for our mini toys).
The lumos projector is affordable and quite easy to set up BUT the navigation on Netflix / other platforms with the remote controller is a chore (that we didn't like at all!). It took us awhile to figure out how to navigate to the "search" button on Netflix and we were really frustrated! Another thing that we disliked was the manual keystone correction. In the future, we'd figured that we'll probably splurge more to get a smarter projector with auto-keystone correction or a TV.
