The hotel sheets have been changed, but the mattresses have not.

What you want to ask is what should I do if the hotel sheets are changed and the mattress is not changed? Contact the hotel management and change the sheets and quilts by yourself.

1. Contact the hotel management: you can contact the hotel front desk or room service department and tell them that the sheets and quilts have not been replaced, and ask them to solve them as soon as possible.

2. Change your own sheets and quilts: If you don't want to wait for the reply from the hotel management, passengers can also change their own sheets and quilts. You can take out the extra sheets and quilts in your luggage and change them yourself.
