Ashley Sleep doesn’t require a break-in period, but you should sleep on your new mattress for at least 30 days to get a better feel for it.
The downside is that you cannot return the mattress if, for some reason, it doesn’t meet your needs.
Ashley Sleep only accepts returns for mattresses that either arrive damaged or have manufacturing defects. Plus, you have only 72 hours to send your new mattress back to the store.

However, some retail stores selling Ashley Sleep products may allow you to try your mattress for 30 nights or longer and return it if necessary.
