I've found two bunk beds I like.
One is 150cm high, but 5 year old DS1 can't sit up in the bottom bunk (would be my 3 year old in bottom bunk, who can sit up, but obviously won't be able to in a year or so). This obviously gives DS1 on top bunk more space.
Or one that is 170cm high, so more space for DS2 on bottom bunk (I think we'd still be able to sit up there and read bedtime stories). This leaves about 25 inches between frame and ceiling for DS1 (i.e. just an inch or two 'space' for DS1 to sit up at the moment).
Any thoughts or experiences welcome, as I'm going a bit crazy bunk bed googling!
I'm 5ft1, so the prospect of changing beds isn't enthralling me either, but it's more important that they last as long as possible (although we are getting bunk beds that can separate into twins as / when needed).
Thanks
