I was lucky enough to secure seat 11A which is in the front row of business class, in a 2 row mini cabin of 8 seats in a 1-2-1 configuration, exactly like F.
Pre-suites SQ had trouble in differentiating its premium cabins, with the latest product on the 77WN the "problem" returns. Which is why you can understand their drive to eliminate F entirely on the A350.
