If you go to http://www.maxi-cosi.com/ot-en and select the car seat you have, ie. CabrioFix, it will show you a picture in the middle of the screen with 4 tabs across the top. Underneath the picture are 3 options, Specifications, Instructions and Instruction Movie. Select Instructions and this will take you to the Instruction Booklet you should have got with the seat (if its not alread tucked in its holder at the back of your seat). There is a section in the booklet that shows/tells you exactly how to get the covers off for washing. Good Luck You could try Kiddicare.com for the head support.
