This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.
