Description

The Silentnight Air Plus 800 Mirapocket® Mattress offers breathable comfort and sturdy support.

Zoned support

Made with you in mind, this mattress includes a core of 800 Mirapocket® springs. These springs are encased in separate fabric pockets to encourage independent movement. The springs respond quickly to keep you supported.

Zoned in the centre third, you will receive firmer support in the areas you need it most like your hips, spine and neck. This helps reduce aches by keeping your body perfectly aligned.

Breathable comfort

Silentnight’s exclusive Air Plus fibre layer is tightly packed to offer firmer comfort. The layer is formed from breathable fibres that increase airflow. This helps to stop heat and moisture from settling inside the mattress so you can enjoy a refreshing sleep.

Adding to the comfort of this mattress is a layer of soft white fibres. These fibres enhance the cushioned comfort and aid with breathability for extra freshness.

In between firmness

Rated medium to firm, you can enjoy a balanced feel of support and comfort. This is a great choice when sharing the bed as it suits most sleepers.

Edge to edge support

This mattress features a sturdy wire rod around the perimeter of the spring unit to create a reinforced rod edge border. It increases the stability of the mattress edge so it does not dip under weight and pressure. So you can sleep comfortably across the entirety of your mattress surface without a ‘roll off’ feel.

Trusted construction

Made by one of the UK’s leading sleep brands, you can rest assured that this mattress was crafted right here in the UK. This means it has been held to high safety standards to ensure great quality.

Certified as a B Corporation™, Silentnight ensures social and environmental practices are to a high level with full transparency. This means your mattress is backed by a company that cares about good practices to give you the best experience.

For added reassurance, the Silentnight Air Plus 800 comes complete with a 5 Year Guarantee.

100-Night Comfort Trial

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.
