Is there a name for this type of chair / chaise

[dr.girlfriend]

What search terms would I use if I was looking for something like this?  Do you guys think it's a two-seater, or two chairs just really close together?

Those are (2) Barcelona (or Barcelona-style) chairs pushed together. Since they have slim metal legs, it can be difficult to see there are (2) legs in the middle and not just one. When chairs are connected together like that, we call them tandem seats in commercial design; I've not seen them used in residential, unless someone is repurposing a commercial piece.
