Silentnight Mattresses

Why choose a Silentnight mattress?

A Silentnight mattress combines established British manufacturing with plenty of choice, making it easier to find the comfort and support that work for your bedroom.

• Silentnight's Mirapocket® springs move independently, allowing the mattress to respond more closely to your shape and helping to limit movement from one sleeper to the other.

• Miracoil® mattresses provide zoned, edge-to-edge support with a steadier and typically firmer feel.

• Selected mattresses use breathable Eco Comfort Fibres™, body-moulding memory foam or responsive UltraGel™ layers, giving you different ways to personalise your comfort.

• A choice of firmness grades means you can compare softer cushioning with medium, firm and extra firm options according to how you prefer your mattress to feel.

• Silentnight mattresses are manufactured in the UK, combining decades of bedmaking experience with modern mattress technologies.

How to choose the right Silentnight mattress

Two of Silentnight's best-known support systems are Mirapocket® and Miracoil®, and each creates a different mattress feel.

Buying guidance for Silentnight mattresses

Silentnight offers several mattress constructions, so choosing between them is easier when you start with the comfort you enjoy. Consider your preferred firmness first, then compare the spring system and comfort layers to find the combination that feels right for you.

Explore popular Silentnight mattress collections

Silentnight combines its spring technologies with a range of comfort materials, giving you plenty of choice.

• Eco Comfort mattresses use breathable Eco Comfort Fibres™, made using recycled plastic bottles, to create comfortable cushioning while allowing air to circulate.

• UltraGel™ mattresses feature a responsive gel-infused comfort layer that moves with you and promotes airflow. Selected UltraGel™ models combine this with Mirapocket® springs for zoned support.

• Memory foam mattresses provide closer, body-moulding cushioning and can be paired with Mirapocket® springs for adaptable support.

• Miracoil® mattresses offer a stable, supportive feel.

The right collection comes down to whether you prefer firmer support, closer cushioning, increased breathability or a responsive combination of springs and comfort materials.

How to select the right firmness grade for your sleep style

Sleeping position is a useful starting point when comparing firmness, although body weight and personal preference will also affect how a mattress feels.

• Side sleepers often prefer soft-to-medium cushioning because it allows more give around the shoulders and hips.

• Back sleepers may prefer medium-to-firm support for a steadier feel through the back and hips.

• Front sleepers often find a medium firm or firm mattress more comfortable because it provides less give around the middle of the body.

• Combination sleepers may prefer a medium or medium firm mattress that balances cushioning with enough responsiveness to make changing position easy.

MattressNextDay's Silentnight range covers soft, medium, medium firm, firm and other comfort choices, so you can use the firmness filters to narrow down your options.

Treat these recommendations as guidance rather than strict rules. A softer mattress may still feel supportive to one person, while another sleeper may prefer something firmer in the same sleeping position.

Silentnight mattress sizes and room compatibility

Silentnight mattresses are available in the main UK mattress sizes, so consider both the sleeper and the available bedroom space.

Measure your bed frame rather than the room alone, and check mattress depth if you use fitted sheets, a low headboard or a bed with built-in features. Deeper pillow-top and premium models may also benefit from deeper-pocket fitted sheets.

Ask the expert about Silentnight mattresses

Choosing a mattress is easier when you know what to compare. Our product experts answer common questions about Silentnight mattresses, including suitability, specific technologies, manufacturer guarantees, and delivery.

Martin Seeley, Product Expert at MattressNextDay, answers questions about Silentnight mattresses.

What are Silentnight Eco Comfort Fibres™?

Eco Comfort Fibres™ are breathable comfort fillings made using recycled plastic bottles. Their open construction allows air to circulate through the comfort layer, while the fibres add soft cushioning above the mattress support system.

They are available across selected Silentnight mattresses rather than every model, so check the individual product specification if Eco Comfort is particularly important to you.

What is Silentnight UltraGel™?

UltraGel™ is Silentnight's responsive gel-infused comfort material. It is designed to adapt as you move while allowing more air to circulate than standard memory foam.

Selected UltraGel™ mattresses combine the material with Mirapocket® springs, creating responsive cushioning alongside zoned pocket spring support.

This can make UltraGel™ worth considering if you tend to feel warm or prefer a comfort layer that springs back more quickly than traditional memory foam.

Do Silentnight mattresses need turning?

It depends on the model.

Some Silentnight mattresses are single-sided, meaning they generally need rotating from head to foot rather than turning over. Others, including the Silentnight Double Sided Miracoil Mattress, have comfort fillings on both sides and are designed to be turned regularly.

Always follow the care instructions supplied with the particular mattress rather than applying one routine across the entire Silentnight range.

Can I use a Silentnight mattress on a slatted bed frame?

Many Silentnight mattresses can be used with a suitable slatted bed frame, but you should check the requirements for the individual model.

Make sure the frame is sturdy, level, and in good condition, and check any guidance on the maximum spacing between the slats. If you are replacing an existing mattress, it is worth checking the frame at the same time so your new mattress receives consistent support.

A sprung divan and a solid or slatted base can also influence how firm a mattress feels.

Which is better for couples, Mirapocket® or Miracoil®?

Both can work well for couples, but they have different strengths.

Mirapocket® is the stronger starting point when partner movement is a priority because each pocket spring moves independently. This can help reduce the amount of movement that travels from one side of the mattress to the other.

Miracoil® creates a firmer, more unified feel with support extending towards the edges. It can therefore suit couples who both prefer a stable and supportive mattress.

Are Silentnight mattresses made in the UK?

Yes, Silentnight mattresses are manufactured in the UK.

Silentnight has more than 80 years of British bedmaking heritage and operates manufacturing facilities in Lancashire. This makes the brand a popular choice for shoppers who value established UK mattress manufacturing alongside a wide range of modern comfort technologies.

What guarantee comes with a Silentnight mattress?

Silentnight mattresses come with manufacturer guarantees that vary by model. Many models offer a guarantee of five or ten years for mattresses and beds. Check the individual product page for the exact guarantee that applies to your chosen mattress. 

Check the product page before ordering and follow the manufacturer's care and bed-base guidance to understand the conditions that apply.

Are Silentnight mattresses tested for quality and safety?

Silentnight mattresses are made to meet relevant UK safety and quality standards, giving you added reassurance when choosing your new mattress. The brand also operates its own testing facilities to check areas such as durability, performance and fire safety.

When comparing Silentnight mattresses at MattressNextDay, you can also look at the individual product specification, comfort rating and guarantee information to help you choose with confidence.

Are Silentnight mattresses environmentally considered?

Silentnight uses a number of sustainability-focused materials and manufacturing initiatives.

Eco Comfort Fibres™, for example, are made using recycled plastic bottles and are used in selected mattresses for breathable cushioning. Silentnight is also a member of the Furniture Industry Sustainability Programme, which covers commitments relating to environmental, social and economic sustainability.

If sustainability is important to your decision, compare the specific materials and certifications listed for the mattress you are considering, as not every Silentnight model will have the same construction.

Can I get free next-day delivery on a Silentnight mattress?

Yes, on qualifying products. Free next-day delivery is available on eligible in-stock Silentnight mattresses across the UK mainland.

Availability may vary by mattress and size, so check the delivery information for your chosen product before ordering.
