For the highest standards of quality and safety
Sleep better with the pressure-relieving, refreshing comfort of the Emma Diamond Spring Free Deluxe Mattress.
Refreshing comfort
Keeping this mattress feeling fresh is a 3cm layer of Diamond DegreeĀ® Energex foam. This foam is infused with graphite and diamond particles to help conduct heat away from your body. The foam also features an open cell structure for increased airflow. This foam layer keeps you feeling cooler and more refreshed compared to traditional Memory foam.
The mattress is made with a Sense ICE cool to touch cover to enhance this fresh comfort.
Pressure relief
Designed with a 5cm layer of Visco Elastic Memory foam that offers sink-in comfort. This layer moulds around your body shape, helping to lift off built-up pressure so you can sleep better. Memory foam is a great comfort layer when sharing the bed as it can reduce motion transfer for a more undisturbed rest.
Deep support
The support of this mattress is delivered by a 21cm deep layer Reflex foam. This foam is dense and sturdy, to provide you with lasting support. The durability of the foam means it keeps its shape for greater longevity.
Convenient design
This mattress is single-sided, this means you do not have to fret about flipping it, simply rotate top to toe seasonally. Maintaining a good rotation schedule can help reduce a build up of dips to the surface for longer use.
Adding to the convenience, the mattress cover is removable and machine washable. Making quick and easy to clean to keep your sleep space feeling brand new.
Delivered vacuum packed and rolled, carrying this mattress to your room and unpacking is made simple.
Emma quality
Made one of the leading brands, this Emma mattress has been made to a high standard. Featuring a generous 10 Year Guarantee for added reassurance so you can purchase with confidence.
This mattress comes with a 100-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 100 nights. If it's not quite right for you, you can exchange it for a new one. To be eligible for the Comfort Trial, you'll need to purchase a mattress protector from MattressOnline with your new mattress.
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.
