Tell me more about the Hypnia Essential Hybrid mattress

The standout feature of the Hypnia Essential Hybrid mattress is its unique blend of layers, which provide excellent comfort and support.

The mattress is composed of pocket springs with 5 support zones, offering targeted support and effective motion absorption.

It also has a Cloud-zoned and memory foam layer for body-contouring support that adapts to pressure points.

The Hypnia Hybrid is comfortable in most sleeping positions, but particularly for side and back sleepers.

It also offers low-motion transfer, so we'd recommend it to couples and restless sleepers. 

One downside is the non-removable cover, though using a mattress protector can help extend its lifespan and cleanliness.

The Simba Hybrid is an award-winning hybrid pocket sprung foam mattress by Simba Sleep. 

This is a medium-firm mattress that's an excellent choice for a wide range of sleepers but is particularly suited to side sleepers. 

The Simba mattress is supportive enough to prevent a build-up of tension but also soft enough to allow your body to sink in where necessary.

This allows for optimal spinal alignment. 

The Simba Hybrid mattress comes with an antibacterial hypoallergenic cover, which is removable and machine-washable.

The Simba comes with free delivery, a 200-day risk-free trial period, and a 10-year guarantee.

Emma NextGen Premium Mattress

The Emma NextGen Premium Mattress offers excellent 7-zone support.
  • Halo memory foam, Airgocell foam & pocket springs
  • 25 cm (9.8 inches)
  • Medium feel

Tell me more about the Emma NextGen Premium mattress

The Emma NextGen Premium mattress includes pocket springs for improved airflow and support, a 7-zone design for adaptive support, and a Halo memory foam that responds to your body's shape. 

While the mattress promotes enhanced airflow, our tester observed that its breathability might not suffice for particularly hot sleepers.

Unfortunately, the foam layers on our test mattress didn't fully expand,  causing some springs to be felt when pressure was applied.

However, Emma's customer service team promptly resolved the issue by sending a new Emma NextGen Premium mattress. 

The mattress also has limited edge support, meaning you may experience a roll-off feel if you sleep on the edge of your bed.

Despite this, the mattress was still comfortable and provided a great night's sleep. 

Reasons to buy

200-night trial period 

10-year guarantee

Machine-washable cover

It features 3 layers of high-quality, high-density memory foam for optimal spinal alignment, pressure relief, and comfort.

The base layer also has 7 contour zones to enhance its ergonomic design and keep your body in a healthy sleeping position. 

The Nectar mattress features a breathable, cooling cover, but it isn't machine-washable.

We'd suggest using a mattress protector to safeguard your mattress against stains, spills, and bacteria.

Who can sleep on a small double mattress?

A small double mattress is a popular choice for people who require a bed that's slightly larger than a single mattress but smaller than a double mattress. 🛏️

Small double mattresses measure 120 x 190 cm (3’9” x 6’2”) and offer a versatile and practical solution for various sleepers and living situations.

They're ideal for people who sleep alone and like to stretch out or for couples who want to save space in the bedroom.

Let's take a closer look at who can benefit from a small double mattress. 👀

A luxurious choice for solo sleepers

A small double mattress is an excellent choice for solo sleepers who value extra space to stretch out and get comfortable without needing all the room a double mattress offers. 😴

Man sleeping with a cat
Small double mattresses are ideal for single sleepers sharing their bed with a pet.

Measuring 120 x 190 cm (3’9” x 6’2”), they are 30 cm (11.8") wider than a single mattress and 15 cm (5.9") shorter than a double mattress.

The small double bed size allows for greater freedom to move at night without taking up too much floor space.

This size is perfect for people who change sleeping positions frequently or like to have extra space for their furry friends.

A space-saving option for couples with limited space

A small double mattress can be a fantastic space-saving solution for couples with limited bedroom space. 👩‍❤️‍👨

It still offers enough space for two people but uses significantly less floor space than a king mattress or super king mattress.

This can be especially helpful for smaller bedrooms or apartments where every centimetre of space counts.

A small double bed ottoman is also a great option for those with limited space, as you get ample storage underneath the bed.

If your partner sleeps quite restlessly, though, you should always choose a mattress with good motion isolation.

sleeping in bed with movement
Couples on a small double mattress should always choose low-motion materials.

Motion isolation (or low motion transfer) means that the mattress absorbs the movements of one person so that you don't feel them on the other side of the bed.

Memory foam or pocketed coils are often used in mattresses with good motion isolation.

We also wouldn't recommend a small double mattress to larger couples or those who like to stretch out.

A good option for guest rooms

A small double mattress can also be a good option for guest rooms.

If you want to create a welcoming and comfortable space for your visitors, it's essential to consider the size and layout of the room. 🤗

A small double bed size offers a balance between providing ample sleeping space for your guests and making the most of the room's available space.

This way, you can ensure your guests feel well-rested during their stay while still leaving room for extra walking space.

Since guest beds won't be used regularly, you could even opt for a cheaper small double mattress option like the Silentnight Eco Comfort.


An excellent upgrade for kids and teenagers

Small double mattresses can also be excellent options for children or teenagers transitioning from a single bed to something more spacious. 👧🏼

Children playing on a small double mattress
For children desiring a roomier bed, small double mattresses provide ample space.

This mattress size offers additional room for growing bodies without taking up too much space in the bedroom.

It's a practical and cost-effective solution for parents who want to provide their children with a comfortable and spacious sleeping surface.

Different types of small double mattresses

So you've decided on a small double bed size, but choosing the right mattress material is crucial for a good night’s sleep.

There are dozens of different materials to choose from, each offering unique benefits and characteristics.

Let's look at some of the most common mattress materials. 👇🏻

Memory foam small double mattresses

Memory foam is a versatile material that adapts well to the body's contours and provides excellent pressure relief and even weight distribution.

This makes it an ideal choice for orthopaedic mattresses.

Memory foam mattress
Memory foam mattresses excel at significantly reducing motion transfer for undisturbed sleep.

Memory foam also offers very low motion transfer, making it a fabulous choice for couples.

On the downside, restless sleepers who change position frequently may not find memory foam suitable

This is because the material allows for good sinkage, which makes it more challenging to move around on.

This doesn't mean all memory foam mattresses are soft. 🧸

Some options, like the Nectar, offer firmer support and are better suited to all body types.


Memory foam does tend to retain body heat, making these mattresses less suitable for hot sleepers or people who sweat a lot while sleeping.

That said, many brands have developed cooling technologies or combined a top layer of ortho memory foam with other materials to solve this issue.

Latex foam small double mattresses

Latex foam mattresses are popular because of their natural resilience and durability. ☘️

They offer a unique combination of support and comfort, conform to the body, and feel slightly bouncier than memory foam.

This makes it easier for you to change positions throughout the night.

Benefits of latex mattresses
Latex mattresses combine eco-friendliness, hypoallergenic properties, and breathability for optimal comfort.

These comfortable mattresses are also hypoallergenic and resistant to dust mites, making them a great choice for allergy sufferers. 🐜

They're also naturally breathable, which helps regulate body temperature and keeps you cool throughout the night.

You'll find both natural and synthetic latex foam mattresses, with the former being more eco-friendly and sustainable.

On the downside, latex mattresses can be quite expensive, reflecting their premium quality and durability.

The Hypnia Supreme Hybrid mattress is an excellent budget-friendly choice with latex, foam, and pocket spring layers.


Coil or pocket spring small double mattresses

Innerspring mattresses have long been a popular choice for sleepers.

With a core of interconnected springs, these mattresses offer a traditional feel and plenty of bounce.

Spring mattress layers
Natural ventilation channels are formed by the gaps between the springs in the mattress.

The spaces between the springs create natural ventilation channels that provide excellent breathability. 🌬️

This design ensures top-notch climate regulation and prevents the formation of mould and dust mites.

These coil mattresses, with their firmer and more stable structure, are an excellent choice for people with heavier weights as well as for back and stomach sleepers.

On the downside, you'll likely come across poor-quality innerspring mattresses.

We'd recommend sticking to pocket-sprung mattresses or hybrids, like the small double Simba mattresses.


Pocket springs are individually encased in fabric for better motion isolation and targeted support.

This design ensures that each spring can respond independently to your body and weight, improving comfort and spinal alignment.

How to select the right firmness level

Before buying a mattress, it's important to determine the right degree of firmness.

The firmness level of a mattress indicates how soft or hard the surface of the mattress feels when you lie on it.

There are multiple factors that influence which degree of firmness will be right for you, but build and body weight certainly play a part. ⚖️

  • Heavier people generally find that a firmer mattress provides better support.
  • Lighter people may prefer a softer mattress that adapts better to their body shape.

The Emma Original is a fantastic medium-firm mattress option that still offers great stability and support.


Sleep Hero firmness scale
It's important to choose the right mattress firmness for your preferred sleeping position.

It's also helpful to consider your preferred sleeping position and other personal preferences.

Back sleepers and stomach sleepers, for example, usually require slightly firmer mattresses than side sleepers.

Criteria to consider before purchasing a 120 x 190 cm small double mattress

Buying a small double mattress isn't always the easiest of tasks.

You need to ensure you are investing in a high-quality product. 🏅

But how do you figure this out?

Let's explore the key aspects to keep in mind during your search. 🔎

Quality and density of the materials

High-quality materials not only ensure a comfortable sleeping experience but also contribute to the longevity of the mattress. 🗓️

Mattresses made with higher-density materials tend to provide better support and retain their shape over time, making them a wise investment.

While premium mattresses like the Simba Hybrid Luxe will be top-of-the-notch, most of the brands we recommend actually offer high-quality products.


Stability, support, and firmness

Stability, support, and firmness play a significant role in determining your overall comfort and sleep quality.

A mattress with good stability and support will keep your spine aligned and alleviate pressure points, helping to prevent discomfort and back pain.

Firmness, on the other hand, is a personal preference that varies among individuals.

Mattress firmness
The correct firmness depends on your body type and favoured sleeping position.

Choosing a mattress with a firmness level that suits your sleeping position and body type is essential, as this will ensure optimal comfort and restorative sleep.

Your mattress doesn't need to be extra firm to offer the right amount of stability and support.

It just needs to provide firmness and support, which is suitable for your body weight and sleeping position.

Delivery and return conditions

Delivery and return conditions can significantly impact your overall shopping experience. 🚛

Reliable delivery ensures your new mattress arrives on time and in perfect condition.

Many mattress companies in the UK offer free delivery and returns.

Reviewing the return policy is essential, as it's not uncommon to realise a mattress isn't the right fit after a few nights of sleep.

A generous return policy will give you peace of mind and the opportunity to exchange the mattress if it doesn't meet your expectations.

Risk-free trial period

A risk-free trial period is an essential factor to consider when purchasing a new mattress.

risk-free trial period
Most UK brands offer risk-free trial periods.

A trial period allows you to test the mattress in the comfort of your own home, ensuring it meets your specific needs and preferences. 🏡

Typically, mattress companies offer trial periods ranging from 30 to 200 nights.

Some brands, like Nectar, even offer longer trial periods.

The Nectar Hybrid mattress includes a 365-day trial period, so you can test the mattress for an entire year before deciding if it's right for you.


If you're unsatisfied with your purchase, the company will exchange the mattress for a different model or provide a full refund. 💰

Best small double mattress UK:

Frequently asked questions

  • Wha size is a small double mattress in the UK?

    A small double bed size in the UK measures 120 x 190 cm (3’9” x 6’2”).

  • Is small double the same as queen size?

    What was once referred to as queen size is now more commonly called a small double.

    A small double mattress measures 120 x 190 cm (3’9” x 6’2”).

  • Can a small double bed comfortably fit two people?

    A small double bed size can accommodate two people, but it might be a tight fit.

    A small double bed provides less individual space for each person than a standard double bed.

    If both sleepers are comfortable with the limited space, it could work. 👫🏼

    However, a larger bed size might be more suitable for better comfort and personal space.

  • What are the different innerspring small double mattresses available?

    There are several types of innerspring small double mattresses, each offering unique benefits.

    • The traditional open coil spring mattress features interconnected springs that offer robust support. 
    • The Miracoil mattress is known for its edge support and reduced partner disturbance.
    • In pocket spring mattresses, each spring is individually housed in a fabric pocket for greater support and motion isolation. 

    We would usually recommend opting for pocket-sprung mattresses.

  • Which small double mattress is better, a pocket spring mattress or a memory mattress?

    The choice between a pocket spring and a memory foam small double mattress depends largely on personal preferences. 

    • Pocket mattresses often provide better airflow, resulting in a cooler sleep, and they typically offer more bounce. 💨
    • Memory mattresses, on the other hand, are known for their pressure relief and body-contouring properties.

    Consider your sleep preferences, such as firmness, support, and temperature regulation, when making your decision.

  • Will a double mattress topper fit a small double bed?

    A double mattress topper will not fit a small double bed properly. 

    A standard double mattress topper is designed for a mattress measuring 135 x 190 cm (4’6” x 6’3”). 

    A small double bed mattress only measures 120 x 190 cm (3’9” x 6’2”). 🫠

    Invest in a mattress topper designed for smaller dimensions to ensure the best fit. 

  • Should you get a small double mattress topper?

    Toppers add an extra layer of comfort to your mattress and improve your sleeping experience. 💤

    If your current mattress is just a bit too firm, a topper can add cushioning and be an affordable alternative to buying a new mattress.

    But it's worth remembering that mattress toppers won't save you from the discomfort of a worn, old mattress.

    If you're struggling with a mattress that's sagging or lacking support, you'll need to buy a new mattress.

    Our favourite small double mattress toppers include the Panda mattress topper and Simba mattress topper

  • Can you get small double bedding?

    One downside of small double mattresses is that options may be more limited when it comes to bedding. 

    To complete your bed set, you need:

    • Small double mattress protector
    • Small double bed sheets
    • Double duvet & cover 

    Instead of purchasing a small double duvet, you can just use a regular double duvet. 

    It's important to check your sizes before making a purchase, as not all retailers offer small double bedding. 


  • Which small double bed frame should I get?

    Mattresses should be placed on suitable bed frames.

    But any bed, regardless of divan base, ottoman bed, or slatted bed frame, should work.

    Many popular retailers only sell bed frames for double beds and larger, but you can browse Argos, HappyBeds, and Dreams for small double bed frames.

    A small double bed with a mattress included or small double divan beds are also a great idea for those who need a full bed set. 

    We recommend a small double bed with storage included for those with limited space in the home.
