I've not tried using a camp bed (presumably you have one of those low ones with tensioned wire legs?) in a bivvy tent - but I'd say you will be pretty close to the canvas. Perhaps someone else has tried and can give a definitive answer?
Yes one of the low wire legged ones can be used down the centre of a pup tent. Assuming it's not too long of course! They do come in a variety of lengths.
There you go then Steiner, sorted.
Aw... I'm not buying yet another campbed! If you say my modern one should fit in the Zelt tent, may I use that instead please?
You've got nothing to ein, zwei, drei, vier
No need to buy another camp bed, I'm sure it will be OK - you will just be closer to the roof! (and I said you can't get a campbed into a zelt!).
Given the monsterous size of my camp bed I think I'm going to have to rig up some sort of shelter with my plash (might get another) and hope its a warm weekend. 
Basically either of the two low ones here would fit in a british pup tent. The tall US Army one wouldn't.

Word to the wise, the high camp beds that are easy to put up fit in a pup tent...... however you may not. I spent an odd weekend at Levisham two years ago in such a predicament where I couldn't move and my nose was milimeters from the canvas, oh and I could only sleep on my back. Getting onto the bed was interesting, as was getting off it. Not recommeded for anyone bigger than me, though as I found it erm "interesting" and definately not for the "claustrophobic" , oh and I wouldn't do it again 
Army cot ones that are low, such as steiner it looks is borrowing from us, fit in them fine.
I've got a tan Brit post war thingy that can be borrowed too.
Technically you can fit two men into a pup tent or US shelter halves sleeping head to toe; although it can be a little 'cosy', just as Chommers and Guy.... 
we sleep two to a US pup tent, it's not that bad really.
Shared a pup tent with che at CR OMG another thing I'd never do again

It is if you are sharing with Old 'Un.

I can add another white Bell tent to the growing row. Plus some ammo crates and bits like that to sit on.
Awesome!
Just had a word with John Birchett and us new kids will be up for about 7pm on Saturday, so leave us somewhere to pitch a bell tent and get a BBQ lit. Looking forward to meeting you guys and having a beer or two.
We'll be letting the side down in a modern tent, but at least it's green. We'll pitch up as far away from everyone else as possible anyway, because of the snoring.
