Our Range of Small Double Mattresses

At Simba, we have four different types of small double mattresses that you can choose from. They’re all from our Hybrid® range, and each one is designed to deliver a unique balance of comfort, support, and performance. To help you choose the right Simba mattress for a small double bed, here is a brief overview of each one and what it has to offer:

  • Hybrid® Essential: The Essential is our entry-level small double mattress. Built with 750 springs and 4 layers, this 20cm deep mattress features a CertiPUR® foam base, a Simbatex® cushioning layer, and a breathable zip-off cover, it’s a great choice for providing you with reliable comfort and support night after night.
  • Hybrid® Mattress: The Hybrid® features 1,400 springs and 5 layers. It’s 25cm deep and adds a stabilising core foam layer to enhance support. It also retains the Simbatex® layer and breathable cover, offering a more balanced and responsive sleep surface.
  • Hybrid® Pro: The Pro is our best seller. It’s designed with 3,700 springs and 8 layers, resulting in 28cm of depth. This mattress also includes 2 comfort spring layers, SupportCore™ spring base, and a wool top layer for improved temperature regulation.
  • Hybrid Luxe: The Luxe is our most advanced small double mattress. With 4,400 springs, 9 layers, and a depth of 31cm, it includes 3 comfort springs layers, a SupportCore™ spring base, and a bamboo/wool top layer for next level breathability and comfort.

How to Choose the Right Small Double Mattress for You

To help you choose the right Simba small double mattress for you, there are a couple of factors that we’d like you to take into consideration. They include:

Sleeping position

Different sleeping positions require different levels of support and cushioning to keep your spine properly aligned throughout the night. So, when choosing a mattress, one of the most important factors to consider is whether you prefer to sleep on your back, stomach, or side. Here is the level of firmness we’d recommend for each sleeping position:

  • Side: Soft to medium
  • Back: Medium to firm
  • Stomach: Medium to firm

Body weight

A person who weighs 50 kilograms will experience a mattress very differently from someone who weighs 90 kilograms or more. For example, a lighter individual is more likely to find a firm mattress uncomfortable, while a heavier individual will find that a firm mattress offers them just the right amount of support.

So, when choosing a mattress, take your body weight into consideration. This will help you find a small double mattress that will provide you with the right balance of comfort and support for your body.

Temperature regulation

Often overlooked, a mattress’s temperature regulation properties can make a world of difference to the quality of your sleep, especially if you’re someone who tends to get warm at night.

If you’re a warm sleeper, we recommend opting for a mattress that’s made of natural and breathable materials. Some of Simba’s best small double mattresses for warm sleepers include the Pro and the Luxe.

Motion isolation

If you’re going to be sharing your small double mattress with your partner, you need to pay very close attention to how well the mattress you’re interested in isolates movement. A mattress with good motion isolation can help ensure that movement on one side of the bed doesn’t disturb the other person.

The Simba mattresses that offer the best motion isolation and individual support on either side of the bed include our Pro and Luxe - though our Essential and Hybrid® mattresses are also built to provide a comfortable night’s sleep for both sleepers.

Firmness level

Although different sleeping positions and body weights can benefit from mattresses with different firmness levels, that doesn’t mean you have to completely ignore your personal preferences and what you find comfortable.

So, as far as the firmness of your mattress is concerned, what firmness level you choose to go for is up to you. The most important thing is finding your mattress comfortable from the moment you lay down to the moment you get back up.

Why Choose Simba for Your Small Double Mattress?

Every Simba small double bed mattress is designed and engineered to provide you with the foundation you need to get the best quality sleep night after night. To make sure of that, our expert craftsmen and women combine the highest quality materials with our advanced sleep technology.

After two decades of doing right by our customers, we have sold over 50 million mattresses in 35 countries, are the most 5-star rated mattress brand in the world*, and have won over 100 industry awards. Other reasons why you should choose Simba for your small double mattress include:

  • We offer a 200-night free trial on all our small double mattresses
  • We can deliver your small double mattress the very next day for free
  • All our small double mattresses come with a 10-year guarantee
  • Every 4ft mattress you can buy from Simba is designed here in the UK
  • We offer a number of flexible finance options

  • What size is a small double mattress?

    A standard UK small double mattress measures 120cm (W) x 190cm (L). Compared to a normal double mattress, it is 15cm narrower, which makes it a more compact option for smaller bedrooms or tighter spaces.

  • Is a small double mattress the same as a queen?

    No, a small double mattress is not the same as a queen-size mattress. In the UK, queen-size mattresses typically measure 150cm (W) x 200cm (L), which means they’re 30cm wider and 10cm longer compared to their small double counterparts.

  • Is a small double big enough for two adults?

    Yes, a small double mattress can be big enough to comfortably accommodate two adults. That said, since it’s narrower (by 15cm) compared to a standard double mattress, it’s important to consider how much space you and your partner need and how you both sleep.

  • Can I try a Simba mattress before buying?

    Absolutely, and in fact, we would highly recommend it. The retailers who currently carry our mattresses include Bensons for Beds, John Lewis, and Barker and Stonehouse. So, if they have a showroom nearby where you live, you’re more than welcome to visit in person and get a feel for the ¾ mattress you’re considering before making your decision.

    If you’re not sure where the nearest Bensons for Beds, John Lewis, or Barker and Stonehouse showroom is, you can use our store finder tool to quickly locate it. If there isn’t a retailer that carries Simba mattresses near you, all mattresses ordered through the Simba website come with a 200-night free trial.

    This trial allows you to sleep on your Simba mattress in your own home and properly assess its comfort, support and overall performance over time. In the unlikely case that it doesn’t meet your expectations, we will come and pick it up and issue you a full refund - no questions asked.

  • What bed frame fits a small double mattress?

    A small double mattress measures 120cm (W) x 190cm (L), so you’ll need to pair it with a bed frame with internal dimensions that match those measurements.
