weird one - how to stop mattres sheet rolling up

[unwashed potato!]

getting very annoyed with my bed as the matress keeps rolling up every time i plunk my butt on the bed which makes it very uncomfortab;e when igo to sleep.

my mum seems to think there is something i can get to stop it doing it but neither of us know the name of it. I have searched for matress sheet ties with no luck so turning here to my bestest pals to help me out.

anyone know of anything that i can use to keep my mattress nice and tightly tied down?

btw i dont tihnk it will make a difference but i have a circle bed

Tuck it in under the mattress.

you can tuck it under the top mattress bit but that actually makes it worse as the sheet is too big to tuck under the amtress but not big enough to tuck under the base.

You can buy special clips that hold in place....hang on *goes off to google*

edit:- heres the link to the sort of thing I was on about

Might be worth trying a baby shop, because some people have them on their babies cots to stop the sheet moving when the baby wriggles.

thanks for the link not too sure if it will work but you helped me with the word to search for, sheet straps so thanks for that.

this is what i got, love the bed but it actually isn't that great for more then one person.
