Buy with Confidence
Try this mattress at home for 60 nights with our free Comfort Trial. If it's not quite right, you can exchange it easily.
How does it work?
- 1
When does the trial start? - Your 60-night Comfort Trial starts the day your new mattress arrives.
- 2
What do you need to do? - Sleep on your new mattress for at least 30 nights, using a mattress protector. This gives your body time to adjust and allows the mattress to settle.
- 3
How do you exchange? - After 30 nights, if it's not quite right, simply get in touch to exchange it for another mattress of the same size - we'll collect your old one when we deliver the new.
Want to upgrade? Simply pay the difference.
If you choose a lower-priced option, the original cost will stay the same.
