Dont buy the mothercare narrow one! I had a mothercare one for dd and it was fab. Well stuffed, lovely soft cosy jersey cover, I was gutted when it finally disintegrated 4 years after she was born!
I went and got a replacement yesterday, got the standard mothercare narrow pillow, £29.99 
It's lumpy in places, limp in other places where it's been folded in the box and the cover is hard scratchy poly cotton. Yuck. It's going back tomorrow and I am swapping for the dream genie one.
