Why choose a Silentnight double mattress?
A Silentnight double mattress is a practical choice for couples, solo sleepers who enjoy extra space or a comfortable guest bedroom.
The range includes different firmness levels, fillings and support systems, so you can choose the feel that suits you. Depending on the mattress, features may include responsive Mirapocket® springs, even Miracoil® support, pressure-relieving memory foam and breathable Eco Comfort Fibres™.
With options to suit different preferences and budgets, finding the right balance of comfort, support, and value is simple.
How to choose the right Silentnight double mattress
Buying for two means considering how both people sleep. Start by comparing your sleeping positions and firmness preferences, then consider movement, body weight, and how much cushioning each of you enjoys.
For a solo sleeper, a double gives you extra room to change position and spread out. Focus on your preferred feel and look for reliable support across the full surface.
Choosing the best firmness
Firmness describes how much give you’ll feel at the surface. It can feel different depending on body weight, fillings and the bed base, so use the comfort grade alongside the full product specification.
Firmness | Who it may suit |
Soft | Side sleepers and lighter sleepers who enjoy deeper cushioning around the shoulders and hips |
Medium | Side sleepers, combination sleepers and couples looking for a versatile middle ground |
Medium firm | Combination, back and front sleepers who want cushioning with a steadier base |
Firm | Many front and back sleepers, plus anyone who prefers to sleep closer to the surface |
Extra firm | Sleepers who actively prefer very little surface give |

Buying guidance for Silentnight double mattresses
Before choosing your Silentnight double mattress, think about how it will fit your bed and bedroom, as well as the comfort and support you need. Take a look at the measurements below to help you compare mattress features based on how you and your partner sleep.
Silentnight double mattress dimensions and fit guide
A standard UK double mattress measures 135cm x 190cm, or 4ft 6in x 6ft 3in. It gives a couple approximately 67.5cm of width each and offers a solo sleeper more room than a single.
Check these measurements before ordering:
What to measure | What to check |
Bed frame | Measure the internal width and length. A European double is usually 140cm x 200cm, so it won’t be an exact match for a standard UK double mattress. |
Bedroom space | Allow enough room to walk around the bed, open doors and use drawers once the wider mattress is in place. |
Delivery route | Check doorways, hallways, corners, stairs and landings, particularly for deeper mattresses delivered flat. |
Slatted base | Make sure the slats are undamaged and spaced according to the mattress manufacturer’s instructions. Check that the frame has suitable central support. |
Divan base | Confirm the base is a standard double and remains flat, level and supportive. A sprung divan may make the mattress feel softer than a platform-top base. |
Bedding depth | Check the mattress depth before buying bedding like fitted sheets or a mattress protector, especially for pillow-top and box-top models. |
A double is a practical choice for many shared bedrooms, although couples who prefer more personal space may want to compare Silentnight king size mattresses before deciding.
Couples' choice: Which Silentnight double mattress is for you?
Use your main concern to narrow down the range:
You wake easily when your partner moves: Compare Mirapocket® models. The springs respond locally to help limit disturbance.
You sleep in different positions: Some models combine adaptable pocket springs with memory foam cushioning.
You want more pressure relief: Look for memory foam, UltraGel® or pillow-top layers that spread weight and create more cushioning around the shoulders and hips.
You tend to sleep near the edge: Choose Miracoil® or a Mirapocket® model with reinforced edges, so more of the 135cm-wide surface feels supportive.
If one person is particularly sensitive to movement, prioritise Mirapocket® construction over spring count alone.

Martin Seeley, Product Expert at MattressNextDay, answers questions about Silentnight double mattresses.
Are Silentnight double mattresses suitable for couples?
Yes. Silentnight double mattresses include motion-isolating Mirapocket® springs, edge-to-edge Miracoil® support and reinforced sides on selected models. Choose Mirapocket® if movement is the priority, or Miracoil® if you both prefer a firmer, steadier surface.
What firmness is best when a couple has different preferences?
A medium or medium firm mattress is often the most practical compromise when one person prefers cushioning and the other wants steadier support. Mirapocket® springs adapt separately beneath each sleeper, while memory foam or a pillow top can soften the surface.
What are Silentnight Eco Comfort Fibres™?
Silentnight Eco Comfort Fibres™ are soft, breathable fillings made using recycled plastic bottles. Sustainably sourced and made with 100% recyclable fibres, they offer a more environmentally considered way to add comfortable cushioning to your mattress.
Their open construction allows air to circulate through the comfort layer, helping you feel cooler as you sleep. Eco Comfort Fibres™ are available in selected Silentnight mattresses across different firmness levels and support systems, with some options also featuring hypoallergenic materials for a fresher sleeping environment.
What’s the difference between Mirapocket® vs Miracoil®?
| Mirapocket® | Miracoil® |
Feel | Responsive and more closely tailored to each sleeper | Even and steady across the full mattress |
Support | Individual pocket springs react separately to changes in weight and position | A continuous zoned spring system creates firm, edge-to-edge support |
Breathability | Air can circulate through the sprung core, with the comfort layers shaping the final feel | The open sprung construction allows air to move through the mattress |
Movement | Stronger motion isolation because each spring responds independently | Connected springs create a more consistent response across the surface |
Best suited to | Couples who want less partner disturbance, reduced roll-together and individualised support | Couples or solo sleepers who prefer firmer support and want to use the full width of the mattress |
Will a Mirapocket mattress stop me feeling my partner move?
Mirapocket® springs can reduce how much movement travels across the mattress because each spring responds independently. No mattress can remove every movement, and the sleepers’ weight, comfort layers and bed base will also affect what you feel.
Is a standard double mattress big enough for two adults?
A standard double can suit two adults who are comfortable with a closer sleeping arrangement. At 135cm wide, it gives each person around 67.5cm. A king adds 15cm of total width and 10cm of length, so compare both sizes if either sleeper wants more room.
