How do I clean the Bugaboo Frog seat?

Hi, Just got a good deal on a used Bugaboo Frog today and trying to wash the fabrics. I removed the seat cover and took the foam and stiffener out of the bottom part, but what about the foam and stiffeners in the seatback part? Are those supposed to come out before washing? Help! Thank you

Hmmmm, I can't remember what I did. I know it mainly all went in the washing machine and I can remember taking the foam and stiffener out of the seat part, but I totally can't remember about the top part! I think I must have just scrubbed it in the sink rather than putting it in the machine...
