Montessori floor bed????

Ok I've got a horrible sleeper. He's almost 6 months... he sleeps in bed with me, and nurses all night.
I tried sleep training him last night and I just can't do it and I mean I TRIED. I was VERY determined..He screamed and looked for me all night 🙁 my daughter was WAY easier to sleep train and I'm all about it but wow it was tough and I don't have the heart to do it anymore, it's not the right fit for him..
I got the crazy idea to do a floor bed that I could slowly transition him to sleeping on his own, I could sleep with and nurse him when he needs.. teach him to go down on his own at bedtime...and naps.. seems like the perfect solution so that I'm at least making progress with him, and teach him independence but still give security. it would be HIS bed HIS room rather than mine. 
Anyone have positive results with a floor bed?? 
I'm sooooo desperate he wakes all night it's horrible I just need a brake in the evenings 😭
