Boiling Lake Of Lava

That's what Mr.FloorSleeper's crib has turned into.  Well, to listen to his cries for help when I lay him down, one would have to draw that conclusion anyway.  The last week or so, I've been spending night after neck-creaking night on my couch while he sleeps peacefully on the living room floor.

Here are our options:

1. Move my bed downstairs into the living room.  I miss it and I'm not opposed to the labor involved so much as the style and function of having a bed where your couch used to be.
2. Take his crib out of my room and just toss the living room rug up there.  Well, then where to put the crib....?  Next.
3. Stand my ground and force him to cry it out in his crib.  This is more of a non-option.  There are 3 other people in the house that don't deserve to also have sleepless nights.  I also don't have the patience to endure the cry-it-out method.  I view it as avoidance and I'm more of an active fixer.
4. Change his mattress.  We've had these issues before and I thought about doing that, but never got around to it.  His sister's mattress looks awfully comfy and she would sleep on the kitchen table if we let her.  Definitely an option.
   
5. Tell Mr. A. that his shift on the couch has started.  He doesn't like our bed anyway because the mattress is too firm.  Well, buddy, how would you like to spend your nights on a soft, squishy couch instead?  Sounds good to me anyway.
