Sleeping in vw golf mk1 cabby

Hello
Sounds like a weird question but I'm planning on travelling round in my golf and wondering if anyone has any experience of sleeping in their car. Is it possible to fold seats down in a certain way for it to work? Or anything I can buy like those car inflatable beds or is it just too small?
Any suggestions welcome 

Well I slept in my Golf (USA Rabbit Diesel 4dr) I just had 2 Pillows, I Lowered the back of the seat as far as it would go, used one pillow against the door, and the other for my head…. Granted it was a rest stop for a couple of hours on a 16 hour trip, as I usually started at 5:30pm to drive about 800 miles, I usually stopped @ 12:30 am as I took to the road after work… It wasn't that bad, the only time I got a rude awakening was when the temps went from 60 down to 30, and it was snowing…I had forgotten a Blanket and or a heavy coat.

Never tried in im my Cabby's though, and I was about 40 years younger when I did it.
