In-person seems like it should be a hard requirement for anything a person will sit on. There is no way to tell anything just by looking at a picture.
The sofa I got had one in-store that was cut in half at all levels, so the construction and materials could all be seen. Any company doing that is probably going to be pretty solid, and if not, it should be obvious.
A lot of people these days are into the mode of order online. Certainly there are a ton of podcasts that offer deals on some of the online furniture companies. I don't think I'd personally do it but then my parents probably wouldn't have ordered a lot of stuff online that I do. (But furniture and big electronics appliances are arguably much more of a hassle to return than other things.)
I’m actually much happier ordering appliances online vs furniture- because appliances I can evaluate in multiple ways that don’t need me to sit on it.
Unfortunately some very comfortable furniture turns out to not be long lasting, as I discovered, even when moderately pricey. Steel frame sofas can bend and break under repeated use because the steel is so thin - if you can bend it by hand, it will fail eventually.
