I think AR will find a useful niche here, IKEA already has an ARKit app and I think it will become standard for any large furniture or home improvement store. One problem with AR is that is won't solve the comfort problem. You don't need to get a "feel" for a bookshelf or a cabinet, but couches, beds and chairs vary a lot in terms of comfort level and you can't really know if something will be comfortable unless you sit or lay on it.
