..and what a daft-sounding Q!
We find that our 4 pillows take up way too much space in the car so this year I am going to get 4 compression sacks to de-size them a bit (they're cheap polyester pillows!).
Thing is, apart from carting a pillow into town and persuading an assistant to let me try one out, I don't know which to get, possibly on line.
the Millets options
What do you think?
