Having watched a few trip report videos on the new Austrian Railjet coaches, I noticed that the seats weren't typical single train seats but rather seats laid out in the style of a small couch with an adjustable and foldable armrest between. I don't quite know what these styles of seats are called, but I did a few print screens of them on the PriestmanGoode website. If you can't see the pictures and/or the link doesn't work, just type "PriestmanGoode Railjet" onto Google and the first result should be "OBB Austrian Federal Railways" that should take you to the page. Anyway, pictures below to give you an idea of what sort of seats I'm talking about.

So now you know what I'm getting it, the discussion I want to start is whether or these type of seats could be suitable for use on rolling stock adapted for the more restrictive British loading gauge? I feel like these kind of seats could provide a bit more space since the gap between them is non-existent, and if they could be implemented on the UK network, does that necessarily mean that they should? I like the design and look of these seats, but I've never actually used them so I can't say whether they'd be worth it. I look forward to hearing all your thoughts in this discussion.
