The description says that the cover can be removed and machine washed, I have the bed and the ready removable cover. It also says, if the cover is removed it voids the warranty. Can I remove my cover or not? What does the warranty actually cover?
We talked to the vendor. Looks like that was an old bullet. While you can remove the cover, they don’t recommend it as many people have trouble getting it back on. Removing the cover will void the warranty.
As to what the warranty covers, it’s laid out pretty clear in the linked warranty.
What’s the firmness level?
It would be considered Medium.
