Mattress toppers?

Question:I have just purchased a duck feather filled mattress topper, now I need to know... what order do I place these items in

1/ topper
2/ wool underlay
3/ E/blanket

I was thinking the E/blanket first on the mattress then the wool underlay and then on top of them the topper.

Some one told me to put the topper then the E/blanket then the wool underlay

Im thinking that will not let the topper work properly

Help me please...

Answers:
You/ve got the order right - only the sheet goes over the topper.
