What if the coffee falls on the mattress?

What should I do if the coffee accidentally falls on the mattress?

I said it was difficult to clean the coffee when it accidentally fell on the mattress. If there are sheets on the bed, I can only take them down for cleaning or replacement.

I said it had invaded the mattress and it was difficult to remove it, so there was almost no way.

Unless you change the mattress or remove the outside of the mattress to update it, it will be more troublesome, which is no different from buying another one.

So we can only add a bedspread on it.
