I had a big quilt that took a considerable place in the summer, she was lying almost folded in the room ... Within seconds FFFOUP, any re-entry into the compactor. Placed behind the seat. You have to spread it (as I did not notice when I placed and now there is a big boursoufflure in the package). I have put the duvet. I have verified that the air space was still working after one month it's ok. Only downside: the bag inside does not seem very strong, it must be handled with care Inside the package there is a special offer 2 years warranty instead of one, if one is at the club on their website, but once you are registered, you must send the invoice and stuff by mail (not practical).
