Have a look at the
seatmap on the VS site - it shows the seat numbers in UC a little more clearly. Just so you are clear - the 744s that fly to SFO (VS19/20) are configuration 4. On those:
1) The upstairs (aka bubble) has 5 rows of 2 suites, numbered 1-5 A and K. Its quiet up there and you may get a chance to talk to the captain or first officer as they wander past to the loo or for a leg stretch.
2) Rows 6 to 11 don't exist.
y) 3) Downstairs in the nose (aka A-zone) you have 7 rows of 2 seats numbered 12 to 19 A and K. This zone is preferred as a) it is quieter, noise wise; b) there is no through foot traffic; c) there is more space between the rows, so there is an extra air of spaciousness compared to everywhere else on the plane. The table for the IFBT uesd to be here but its open space now.
4) Behind the A-zone is the remaining UC cabin with rows numbered 20-25 and 4 suites across for 4 of the 6 rows. At the back of this is the bar. (Its important to spend some time there!

). Generally this is the busiest cabin due to the toilets, galley and bar.
Hence the advice above for 12A & K is good for quiet seats close together. Having said that none of the other seats is particularly bad if you are used to flying EC or PE.
Make sure you get to the clubhouse really early if you want a choice of treatment, plus time for a champagne breakfast.
