A Purotex infused knitted cover makes Silentnight's Oslo Miracoil Cushion Top Mattress truly hypoallergenic, actively fighting off moisture and mould.

The cushion top beneath the surface, combines the soft body hugging effects of memory foam, whilst the 7-zone acupressure pad enables the mattress to evenly distribute your body weight and prevent any strain from building up, even with an extended period of rest. Softening with natural body heat and pressure, memory foam slowly takes on an imprint left by your body, catering to your shape to provide uniquely tailored comfort. This reacts to whichever position you are currently laying in, with the visco elastic foam regaining its original shape once you get out of bed to get ready for the day ahead.

The Miracoil spring system has been an established mainstay of Silentnight for many years due to the way in which it can support two people, without fear of them rolling towards each other accidentally, whilst the reinforced border maximises the usable sleeping space. EcoComfort fibre is used as a supplementary filling; soft yet durable and proven to help regulate your body temperature.

To reassure of its high level of quality and craftsmanship, the Silentnight Oslo Mattress comes with a 5 year guarantee.

Silentnight Miracoil Springs

Miracoil Spring System

Silentnight Miracoil springs are constructed from a single continuous wire, coiled in a way which makes the system not only hardwearing, but able to absorb pressure longitudinally. This prevents sleeping partners from disturbing each other, as they are effectively provided with individual support zones.

Visco Elastic Foam

Memory Foam

As you lie back on the Oslo Mattress, the memory foam allows your body to sink into the cushion top layer slightly. It supports your muscles in comfort and reduces movement during sleep, in turn making you feel more rested and full of energy.

Acupressure Pad

7 Zone Acupressure Pad

The 7 zones of the acupressure pad provide tiered support based around the wisdom that the shoulders and hips require slightly more support.



The Purotex cover reduces moisture, which actively prohibits bacterial growth and reduces other allergens.

EcoComfort Fibre

EcoComfort Fibre

To help keep your body cool, the composition of the EcoComfort fibres actually disperses body heat. This has been scientifically proven.

Prevents Roll Together

No Roll Together

Silentnight's patented Miracoil springs provide a robust core which prevents disturbance between sleeping partners. The effects of movement are localised, meaning that vibrations and pressure from one side of the mattress are not carried over to the other side of the mattress.

Non Turn Easy-Care Mattress

No Need to Turn

Rather conveniently, the Oslo Mattress does not need to be flipped over, as it has been designed as single-sided. To ensure longevity, we do recommend that it is rotated from top-to-tail on a regular basis.

Stretch Fabric Cover

Microquilted Cover

The Oslo's microquilted knitted cover has just the right level of give to allow the memory foam to get to work. It is luxuriously soft but durable.

Medium to Firm Tension

Medium to Firm

This mattress has a medium-firm comfort rating, which makes it suitable for most people.

Oslo Miracoil Mattress Measures 10 Inches Deep

10 Inch Depth

The overall depth measures in at 26cm (10 inches imperial).

Recycled Fillings

Recycled Sources

EcoComfort fibre is composed from a blend of polyester which comes from recycled sources. Silentnight care about the environment as well as your body.

Pressure Relieving

Pressure Relief

You can wake up feeling more energised as the pressure relieving effects of the memory foam and acupressure pad, alleviate the aches and pains picked up from daily life.
