Dog Shelf versus internal cabinets

I'm toying with the idea of having a shelf where my dogs can sleep, instead of having internal cabinets. I think that having a place where the dogs can be off the main mattress will create a better sleeping arrangement for my wife and I. I think I've seen this sort of bed of kids in some teardrops, but wanted to at least point my idea for people to comment. I suppose that the lack of storage, or place to mount electronics is the downside. Here are my derpy dogs, so you understand their size and what I'm dealing with.
