Who knew?

I've been thinking about buying a new mattress lately and discovered that for some reason mattresses, box springs, and beds do not fall under the category of "bedding", but rather are "furniture". Also Bed Bath and Beyond has gone so far beyond that they don't even sell beds (not counting daybeds, which seems like an oxymoron to me), and I have a hunch you probably couldn't buy a bathtub there either. So shouldn't they just be called "Beyond"?
