If you plan to invite a group of friends to enjoy your new pride and joy, then they will need somewhere to sit. Corner seating can be a great way to accommodate numerous people while maintaining a social atmosphere, while bar stools can give the room a traditional feel.
Having seating in the middle of the room can take up far too much space and make areas of the man cave redundant. Custom seating can also be built to incorporate additional storage, maintaining a clean and spacious look.
