Specifications of the Silentnight Seoul Miracoil Memory Mattress

Miracoil Springs

Miracoil Springs

Silentnight's world-popular Miracoil springs are designed to provide you with perfect anatomical support and a great night's rest. The edges are reinforced so you can sleep right up to the edge without any fear of roll off, and each partner in the bed has their own sleep zone, so there won't be roll-together either. The middle region of the mattress has been carefully enhanced to give your hips and lower back the support they need.

Memory Foam

Memory Foam

Memory foam responds to body heat by softening and matching the shape of your body, allowing superb orthopaedic support and incredible comfort. Originally designed by NASA, the memory foam (also known as Visco Elastic) disperses your weight throughout the mattress, alleviating pressure points and allowing freer blood circulation - resulting in an excellently restful night's sleep.

EcoComfort Fibre

EcoComfort Fibre

EcoComfort Fibre - soft recycled polyester fibres that are proven to reduce your temperature as you sleep.

Pressure Relief

Pressure Relief

Provides maximal pressure relief, by spreading more of your body's weight across the mattress - less toss and turning, more restful sleep.



This mattress is hypoallergenic & resistant to dust mites, is ideal for asthma and allergy sufferers, or anyone looking for a healthier night's rest

Medium to Firm
Medium to Firm
Lower Back Support

Lower Back Support

Enhanced support where it's most needed in the lower back area means that this mattress provides suitable support for everyone, great or small.

More Sleep Space

More Sleep Space

Reinforced springs around the mattress edge and a firm rod edge help to make sure that the edge will never wobble, sink or bulge, instead giving you support across the complete mattress surface. You'll be reclaiming valuable space that's usually lost in conventional less edge-stable mattresses.

No Roll Together

No Roll Together

No roll together - the springs are arranged in personal sleep zones, so you can sleep soundly even if your partner rolls over or moves. You won't be disturbed by their motion, and there's no tendency to roll towards the middle.

No Need To Turn

No Need To Turn

This mattress is purposely designed to be single sided for your convenience - there's no need to flip it over, but we do recommend that you rotate the mattress regularly.

Fire Resistant - Low Hazard

Fire Resistant - Low Hazard

This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home

Description of the Silentnight Seoul Miracoil Memory Mattress

The Silentnight Seoul Memory Miracoil Mattress comes from Silentnight's fantastic new range of mattresses - the Select Collection. As Silentnight's entry level Memory Foam mattress you'll find this to be a great value mattress with incredible levels of support and comfort.

First off, let's focus on the Miracoil Springs. As Silentnight's Hippo and Duck demonstrate, they're built to support anyone, regardless of shape and size. With super-stable mattress edges there's no roll- off, and the head-to-foot spring alignment prevents roll-together. There are even three separate support zones - making sure you get enhanced support for the regions that need it the most.

The top layer of the mattress (underneath the soft knitted microquilted cover) is made from memory foam, soothing away pressure points and hugging your body's shape perfectly.

Under this, there's EcoComfort Fibre - a revolutionary earth-friendly comfort layer made from recycled sources. Scientific tests have shown that EcoComfort fibre is such a great bedding material, it even helps cool you while you sleep!

Caring for your mattress is nearly effortless, since it's a rotate-only model - there's no need to turn it over. The Seoul is also hypoallergenic.
