On a different note, I’d advise against wasting extra points/money on PS. I recently flew DTW-LHR in PS. The experience was meh. Sure the seat is a little wider and there is a little more seat pitch, but that’s e where it ends. Same food and service as DC+. Same FAs. Same liquor and wine selection. (Read: no selection, just single choices). In DC+ the arm rests fold up and out of the way. IMHO, PS is a waste. Buy DC+, select seats C E G, and pocket the difference. Maybe no one will sit in D and F and you can spread out. Good luck.
PS seats have more recline as well and there is also a foot rest which extends down and has flap that folds out to put your feet on (most people seem either unaware of it or how it works). Footrest may not be that comfortable if you are taller, but I find it useful in getting sleep. The meal may be disappointing compared to what it used to be, but many here are underselling the seat differences.
