Except the armrests are much narrower than an armrest on a domestic first-class seat, which is what Delta's premium-economy is being compared against by most commentators here and elsewhere.
The only domestic first-class seat comparable to the premium-economy seat is the much-hated seat on the 767-300. 38 inches of pitch and 18 1/2 inches of width. However, the 767-300 is 2x2x2 whereas premium-economy on the A350 is 2x4x2.
The reality is Delta could have gotten innovative with the A350. It could have installed a bar for business-class passengers, much like Virgin and other carriers. It could have went 2x3x2 in premium-economy. It didn't.
I want to try it, but I honestly think that buying a row of three economy-class seats will be the most comfortable option unless you have the budget for business-class.
