Hi there! I am in Scotland and use terry nappies at night. You do hvae to fold them, kust as you would baby ones, but they are much more flexible that pre-made ones and easier to wash and dry.
if you go to
http://www.drylife.co.uk/index.php you will see a range of suitable terry squares and platic pants - the ones I use actually. At my wist size a 48" square, folded as shown fits fine thouh I use a couple of baby nappies foled up insde as well to contine any floods. You could trey an old towel inside if you wanted.
The advantage of the terry squares is when you come to dry them - they wash and dry flat so don't take any longer than any other towel. A pre-f;od with mutli layers take nuch longer.
Washing is easy but always run them though a rinse cycle before the wash to wash away the urine and there should not be any smell.
Dry life allow you to buy singles of nappies so you can try the system out without much cost - maybe £15 even. Give it a go and see how you get on.
Oh, and I always sleep on am absobent pad
http://www.allaboutincontinence.co.uk/catalogue/browse.php?product_Category_ID=130&parent=128 usually I have to buy a single one with flaps and cut off the flaps and these sit in place on the matress and cath any leaks. It saves making my wife any hotter with a waterproof matress cover!
Finally, don't forget nappy pins with the nappies!
