Be careful though. You probably have the same window frames as we do. The dual recliners we bought were for an RV and came in 67" and Fit like a glove.
Assembly would have been simple enough but the tabs would not lock together until I did some tweaking of the frame. Came in 5 pieces so it gets through a small door.
