Small Double Memory Foam Mattresses


How Big is a Small Double Mattress?

Dimensions are 120 cm x 190 cm or 4’0 x 6’4 mattress size. It’s commonly known as a 4ft small double.

Our Design

Each and every memory foam mattress in our collection is made from the highest quality materials, manufactured by our sleep experts in our Yorkshire factory. We’ve been designing and producing memory foam products since 2001, so we have plenty of experience in the industry. However, we’ve also been around since the 1970s, which has given us plenty of understanding about beds and mattresses. 

Our innovative designs ensure you benefit from complete body support and comfortable and undisturbed sleep. We know what it takes to create a good night’s sleep, which is why we strive to provide this for each of our customers. 

Our Range of Small Double Mattresses 

Struggling to decide which type of small double mattress is right for you? Let’s shine a spotlight on some of our bestsellers and what they offer to help you make your choice. 

Pocket Spring Mattresses

The Zen Memory Foam with 1000 pocket springs is one of our most popular pocket sprung memory foam mattresses. The hybrid design gives you the best of both worlds; combining traditional springs with a memory foam layer. Each individual spring provides high support levels, enhanced by the benefits of memory foam.

These pressure relieving mattresses are perfect for those who need pressure point relief, or for couples with notable weight differences. The design ensures your bodies are supported adequately.

This mattress also features cooling technology to ensure you don’t overheat at night. The Coolmax fabric maintains airflow and reacts to your body temperature while you sleep.

Not only that, but it comes with a machine washable cover for protection. This helps to keep it as long-lasting as possible. We’re so confident you’ll be satisfied with this product and what it offers, it comes with a 5-year warranty. 

Looking for something different? Our 4G Aircool pocket sprung mattress is another that features a hybrid design combined with cooling technology. It has 1500 individual springs that provide high support levels, reacting independently to any changes in weight. They also respond to your natural movement while you sleep, a huge advantage, particularly when there are significant size differences in couples. 

The mattress depth is 23cm, offering soft support, making it particularly well-suited to side sleepers. Another exciting feature it offers is its eucalyptus-infused fabric, which is ideal for sensitive skin, as it absorbs moisture and prevents bacteria. You’ll struggle to find luxury at this price anywhere else. Plus, it comes with a 10-year warranty. 

Kids Mattress

Is your child lucky enough to be upgrading to a double bed? We have a range of kids memory foam mattresses for you to choose from. This Coolmax child mattress is made using advanced cooling fabrics to provide moisture disbursement and a comfortable base to sleep on. If your child is prone to getting sleepless nights due to overheating, this is great news.

To help protect it from spillages and stains, this mattress comes with a washable cover. It’s also hypoallergenic and dust mite resistant, which makes for a healthy sleeping environment.  For your peace of mind, it has a one-year warranty. 

Essentials Mattress 

We believe that getting a restful night’s sleep needn’t break the bank. Our Essentials range is specifically designed for those on a budget; finding the balance between affordability and luxury. It’s our most basic range, yet still includes the features you need, such as hypoallergenic materials. 

Our Essentials reflex foam mattress offers firm support, perfect for front or back sleepers. It also comes with a removable cover and a 15cm mattress depth. It’s a hugely popular product for guest bedrooms or rented and student accommodation.

How to Choose Your Small Memory Foam Mattress

Sleep is a very personal experience, which means you need to weigh up a number of different factors when it comes to choosing the right mattress for you. A mattress buying guide can help point you in the right direction. You should also consider: 

Bed Base

Your mattress needs to be adequately supported by your bed frame to prevent sagging and provide the highest comfort levels. Ideally, you should ensure the slats aren’t too far apart, for example. Your small double bed should be made from the highest quality materials alone. 

Sleeping Position

The position you tend to sleep in should play a big role in helping you make your selection. Pay close attention to firmness here. If you prefer to sleep on your side, it’s best to go for a soft feel that allows you to move freely.

If you sleep on your stomach, you should look for an extra firm product, to ensure your spine doesn’t bend during the night. Those who lie on their back need to ensure it is adequately supported and aligned. 


Try having a budget and sticking to it. While it’s tempting to go for the cheapest option alone, remember that a mattress is an investment. If looked after properly, it can last you a long time. So, make sure you find one within your price range that suits your needs.

Room Size

Which room is your 4ft mattress intended to go in? A 4ft mattress is the ideal choice if you have a limited amount of space or are in need of one for a smaller guest room.

Why Memory Foam? 

Whatever your preference or taste, memory foam is a universally liked material. It offers a number of exciting features and benefits, including:
