On the front seat of a mini in Lyons town centre. This was 35 years ago - the back seat and roof rack was packed with camping equipment - we'd driven as far as we could and were close to exhaustion. Mr Woo gave up - got a sleeping bag out and slept under the car.

12 hour bus journey to London

You know when its that bad when you just have to lie down , nomatter what

I was watching QVC the other night (yes its my guilty pleasure) and the bloke selling sealy beds on there said that they have done research and out of lack of food, lack of water or lack of sleep, lack of sleep would kill you first.   Dont know how true that is, but if QVC said it, then it must be true!!!

I can't sleep anywhere except a bed!  On a very rare occasion I have slept on the sofa but tossed and turned too much and ended up back in bed or awake watching TV.  I've tried napping on the sofa....can't do that either.  

There's not a chance of me falling asleep on a bus or plane either.

I love my bed with all my heart

I could fall asleep standing up if I got a minutes peace  When I sleep I'm out...gone...a bomb wouldn't wake me..BUT...it's only for a few hours. More than 5 hours sleep and I feel like crap. I sometimes have an afternoon 30min power nap but that's it 

Im like you, Ellis, i cant sleep unless im lying down. 

Cagney, i am a deep sleeper when im gone, im gone!

Apart from your snoring and talking!!

most uncomfy? that will be bed, with you and the three cats, and a laptop and a tv remote, I am lucky to still be hanging on the edge of the bed by morning!!

Guilty on all accounts I was gonna say in recent times, the cats , cant get your legs down straight, they can take up a WHOLE kingsize bed. But then, I shouldnt grumble at least they grant us a small corner of their bed to rest our weary heads.

Maybe someone else's 'lack of sleep' would kill you first? 

Bathroom floor

I've done that before but I was so wasted it really didn't feel uncomfortable at the time.

True

under a rowing boat on Arran in the rain. 

Oow Slinki that sounds horrible

and you're complaining? Spare a thought for poor Arran.

On a cheap Argos fold-up camp bed. I'd take the cold hard floor anytime over that piece of crap.

A lilo...DO YOU REALISE HOW MUCH SOUND IT MAKES WHEN YOU MOVE!!!?!?!?!?!?!?!?!?! 

hahah! No man is an island  

aye, right, it was the beans!  

Glad I never typed " in Arran" ! 

It was cold and the ground was rocky and the boat was reeking! Stayed fairly dry though

They are all sweaters though. 

and having spammed the thread.. I'll crawl back under my boat!

and jumpers 

You've got to stop creeping up behind them! 

In the boot of a Peugeot 205 in a car park in Birmingham.

Although these days I cannot sleep unless I am in a bed, I can't even snooze on the sofa.  AND if I might be so bold as to add, my bed is the most comfortable bed in the whole wide world.  In fact after we bought the bed we were in the store where we bought it looking at something else and I saw two people trying out 'our' bed and I couldn't help myself I had to go over and tell them them that they wouldn't regret buying it. 

In an overflow french countryside youth hostel. My wish to exterminate mosquitos dates back to tht time.

Kneeling, with my head resting on the rim of a toilet seat. 

I must have slept comfortably, but the most uncomfortable I have felt is leaving the loo and wondering how long I had been asleep in there  

(sitting on the loo I might add ,)

Seems like a lot of us have done it at some point  . As you say - it feels OK at the time.

On an overnight ferry to Ireland, we were sitting in a booth-type thing, my head was on the table, and the ferry was listing from side to side.

I remember some passengers were running past to be sick, the crossing was so rough......I didn't feel nauseous, just wanted to get some sleep so badly, lol.

Edit: whenever I hear Savage Garden's "Truly Madly Deeply" it always reminds me of being on that ferry, cos it was on the music channel on the lounge TV constantly.

Oh gawd the memories (begone) of night ferries to Ireland........(Can feel the nausea now)

 Yeah of course, but that's not a REMEMBERED place of sleeping, unless they added the nasty U shaped toilet mat as a 'sick bib'.  

BTW that never happened to me but I was just thinking about being there now.

In a hammock which was tied to a tree and the wing mirror of a car.

Started off extremely well - ended up with most of the ropes broken and most of me on the floor.  I did have one leg which remained off of the ground; a result in itself, I think

I would like to point out that I was talking about sitting on the the loo and resting my eyes, only to wake up gawd knows how long after...... 

When I woke up, I looked in the mirror and found that I had an imprint of the toilet seat on my forehead!

I had a stippled effect from the bath mat on the side of my face. Very classy!
