Why choose a Silentnight single mattress?
A Silentnight single mattress brings together reliable support, comfortable fillings and the quality of a trusted British sleep brand. With different firmness levels, spring systems and comfort options available, it’s easy to find a mattress for a child, teenager, guest or solo sleeper.
Look out for features such as responsive Mirapocket® springs, supportive Miracoil® systems, breathable Eco Comfort Fibres™ and hypoallergenic finishes. Whatever your budget or preferred feel, there’s a Silentnight single mattress to help you sleep comfortably.
How to choose the right Silentnight single mattress
Start with who’ll use the mattress and how often. An everyday mattress for an adult or teenager may justify a more responsive spring system and deeper comfort layers, while a simpler model can work well in an occasional guest room.
Then compare:
Firmness: side sleepers often prefer more cushioning, while many back and front sleepers favour a steadier medium firm or firm surface. Body weight and personal preference will also change how the mattress feels.
Support system: choose Miracoil® for zoned, edge-to-edge support or Mirapocket® for springs that respond independently to the body.
Comfort fillings: memory foam creates a closer, cushioned feel, while breathable fibres and airflow features may suit sleepers who tend to feel warm.
Mattress depth: measure the bed frame and consider the finished bed height, especially for a child’s bunk or cabin bed.
Use the product filters to compare firmness, support, fillings, depth and price, then check the individual product description and guarantee before ordering.
Silentnight single mattresses for children and bunk beds
Shopping for a child? Explore Silentnight’s kids' mattresses, which are designed with growing bodies in mind. You’ll find different firmness levels and support systems, alongside practical features such as breathable fillings, hypoallergenic finishes and waterproof surfaces.

Buying guidance for Silentnight single mattresses
Whether you’re choosing a mattress for your child, replacing the mattress on a bunk bed or making a guest room more comfortable, Silentnight offers single mattresses in a range of firmness levels and support styles. Think about who’ll be sleeping on it, how firm they like their mattress and which features will make everyday life easier.
Eco-friendly and hypoallergenic options
For a more environmentally conscious choice, look for a Silentnight single mattress made with Eco Comfort Fibres™. Made from recycled plastic bottles, these breathable fibres provide a comfortable and cushioned feel.
Selected mattresses also feature hypoallergenic finishes, making them a practical choice for children, teenagers, guests and anyone who prefers a fresher sleeping environment.
Silentnight single mattress dimensions and bed base compatibility
A standard UK single mattress measures 90cm x 190cm, or 3ft x 6ft 3in. Measure the inside of the bed frame before ordering, particularly if you’re replacing an older mattress or buying for a frame described as European single, small single or custom-sized.
The base can affect both comfort and wear:
Bed base | What to check | How it may affect the feel |
Slatted frame | Confirm the slat spacing meets the mattress manufacturer’s guidance and replace damaged or bowed slats. | Sprung slats can add a little give, while solid slats usually create a steadier feel. |
Platform-top divan | Make sure the surface is flat, supportive and the correct single size. | Usually gives the mattress a firmer, more stable foundation. |
Sprung divan | Check that the base is in good condition and suitable for the chosen model. | Can add extra responsiveness and make the overall setup feel slightly softer. |
Bunk or cabin bed | Follow the frame’s size and maximum mattress-depth instructions. | The right depth preserves the intended guard-rail clearance and finished bed height. |

Martin Seeley, Product Expert at MattressNextDay, answers questions about Silentnight single mattresses.
How long is the guarantee on a Silentnight single mattress?
Silentnight Miracoil®, Mirapocket®, Essentials and Healthy Growth mattresses come with a five-year manufacturer’s guarantee. It covers qualifying manufacturing issues under the stated terms, so keep your proof of purchase and follow the care and bed-base instructions supplied with the mattress.
Always check the individual product page before ordering, as guarantee length and conditions can vary across ranges.
Which firmness should I choose for a Silentnight single mattress?
Choose firmness according to the sleeper’s position, body weight and preferred feel. A soft or medium mattress gives side sleepers more cushioning around the shoulders and hips, while medium firm and firm options create a steadier surface that many back and front sleepers prefer.
Treat the comfort grade as a guide, since two mattresses with the same rating can feel different depending on their spring and filling configurations. Compare the product description, customer reviews, and the firmness label.
Can I use a Silentnight single mattress on a bunk bed?
Yes, if the mattress is the correct size and its depth meets the bunk-bed manufacturer’s safety guidelines. Silentnight’s Healthy Growth range includes models specifically designed for bunk and cabin beds, giving you a clearer place to start.
Check the product description for suitability and measure from the bed base to the top of the safety rail before buying. A standard-depth adult mattress may sit too high for the frame.
Miracoil® vs Mirapocket®: Which Silentnight technology is best?
| Miracoil® | Mirapocket® |
Feel | Even and steady across the mattress | More tailored and responsive |
Support | Zoned support with a stable edge-to-edge surface | Individual springs adapt more closely to the body |
Breathability | The sprung core allows air to move through the mattress | The pocket-sprung core supports airflow, with the final feel shaped by the comfort layers |
Movement | Connected springs respond together, creating a consistent surface | Independent springs improve motion isolation by limiting movement across the mattress |
Best suited to | Sleepers who value firm, even support and full use of the single mattress | Sleepers who want more individualised support and a mattress that responds as they change position |
Do Silentnight single mattresses need turning?
It depends on the model. Some Silentnight mattresses are single-sided and need regular rotation from head to foot, while double-sided models may also need turning.
Follow the care label and product instructions, as using the wrong routine could cause uneven wear. Rotate or rotate with another person if the mattress is heavy, and make sure the base remains supportive and level.
How much do Silentnight single mattresses cost?
Silentnight single mattresses at MattressNextDay can vary in price, so there are options for everyone, even if you’re looking for an occasional guest bed or a mattress to be used every night.
Models at the lower end of the range tend to use simpler spring systems and comfort layers. Spending more can give you higher spring counts, deeper fillings, cooling materials or a more individually responsive Mirapocket® system.
Our Lowest Price Promise provides additional price assurance once you’ve found the right model. Our team checks prices against our main listed competitors every 24 hours. If you find an identical Silentnight mattress for less with one of those retailers, we’ll match the price, while you’ll still receive MattressNextDay’s speedy delivery and customer care at no extra cost.
