As far as there is already a loft bed / bunk bed from Rico what better find.
And for an idea like that, I don't think you need a detailed explanation with three pictures,
but I'm glad you made the effort.
Best still with video xD
@Picasso22 are you kidding
would have done differently
Maybe I'll send another picture when I get home.
I find it quite large and also otherwise not very nice, that could have been done better
Doesn't look very good, and takes up a lot of space.
@127070 What is very much space? 4 blocks in the side and 3 in the height.
A nice and simple bed.
@127070 Please don't put your picture in every comment.
Turned out pretty good.
I think it looks nice.
You get a thousand likes from me.
