When to Buy a New Futon Cover Set
The best tip that you can really have is to buy extra covers for futons set once you buy your futon already so that you will immediately have a replacement when you need it. But if you have not done that yet, here are some reasons why you will need a new set immediately.
First of all, there is obvious wear and tear on the surface. If that is cotton or polyester, you will see tears and scratches on it; get rid of it already. If there are stains on the cover, and there is absolutely no way in which you can hide that anymore, you should definitely get a new one ASAP. You do not have to be a rocket scientist to know when you have to do this, really.
