When making your mind up about the ideal mattress size, there are a few factors to consider. One of the first steps is to take into account the size of your bedroom and the space available. You should also take the opportunity to evaluate your own sleeping habits, to see the type of sleeper you are. This will depend on factors such as your age, posture, body weight, and preferred sleeping position.

Some double mattresses are designed to accommodate different sleep types and body types. There are also different types of double mattresses, designed with different layers of materials. So this is the perfect time to consider if you’re looking for benefits like comfort, luxury, pressure relief, or temperature control. So let’s dive in and find out the types and sizes of mattresses that are available on the market to help you find your ultimate double mattress match.

How big is a double mattress?

When you first start searching for the best double size mattress, it might seem like every mattress looks exactly the same. However, there are actually different sizes of double mattresses, and this will vary from store to store and depend on availability. In most stores, you’ll be able to find two sizes. These typically include small double mattresses, with dimensions of 120 cm x 190cm or 4.0 ft x 6.3 ft. You can also find a regular-sized double mattress, with dimensions of 135 cm x 190 cm or 4.6 ft x 6.3 ft. In some stores, a small double mattress is also referred to as a full mattress and a larger double mattress is known as a queen-sized mattress. In this case, the full mattress is measured at 54 inches x 75 inches and weighs 68 LBS. The Queen mattress measures at 60 inches x 80 inches and weighs 74 LBS.

When to choose a double size mattress?

The next question some people might as is when would you choose a double mattress. And it’s a good question. So one of the first factors to consider would be your age. When most people reach their pre-teens or teenage years, it’s usually the time that they decide to upgrade from a single to a double mattress. For most adult years, it’s true that the world of mattresses really is your oyster. Most adults would choose a double bed to accommodate their needs. For those looking for a little more luxury or extra space, they might choose a king-sized mattress.

Another factor to consider your body type, your height, and the amount of space it would take for you to be comfortable. Many experts recommend that you should choose a mattress that is 10cm longer than your height. If you want to measure the width, then a top tip is to place both your hands underneath your head, and ensure that both your elbows don’t reach the mattress edge. The type of double mattress will depend on whether you sleep alone, with a partner, or prefer some extra space to stretch out on. We’ll go into this further below.

What is the difference between a double and a small double?

The differences between small double mattresses and large double mattresses many seem small, but they can make a big difference to your sleeping experience. Small double size mattresses are usually recommended for one person. These are bigger than a single bed, so are perfect for one average-sized adult, if they prefer a little extra space. Small double mattresses can generally accommodate two average-sized adults, but the sleeping space will be a bit tight. If you have a smaller bedroom or a room that is a little cluttered, then a small-sized mattress is an ideal choice.

There are also numerous reasons to choose a larger double size mattress. This sized mattress is recommended if you love the idea of stretching out while they sleep and having a little extra room. Since there is more sleeping space than the smaller-sized mattress, this size is recommended for two average-sized adults. This means most couples would prefer this sized mattress. If you have a larger bedroom that can accommodate a larger double mattress, then this size would be ideal.

Are UK double sizes the same as EU double sizes?

In different regions and stores, there are different measurements for small double size mattresses and larger double size mattresses. Now we know this can be a little confusing, but it’s because the sizes in the UK differ from those in Europe. In the UK, the sizes for a small double size mattress and a large double size mattress range from 120 cm x 190cm to 135 cm x 190 cm. In Europe, the sizes range from 4.0 ft x 6.3 ft to 4.6 ft x 6.3 ft. Some stores also measure in inches, so the sizes range from 54 inches x 75 inches to 60 inches x 80 inches. Of course, this depends on the store, so you should make sure you check the dimensions before you buy.

The types of double mattresses

Once you’ve decided between a small double size mattress and a larger double size mattress, then the next step is to choose the type of mattress that suits your need. There are actually plenty of mattress types to choose from. Here are some of the most popular ones:

Memory foam double mattresses

If you’re looking for a comfortable mattress that offers great support, then you should consider a memory foam double mattress. This is one of the best double size mattresses types and is designed to suit any sleep type. The foam is temperature-sensitive. Memory foam mattresses are also a good option if you have any back or neck pain, as they are designed to help provide pressure point relief, as well as targeted support for any discomfort. If you’re looking for extra softness, then memory foam double mattresses are also engineered for comfort and will have less of a bounce factor than other types. In addition, memory foam double mattresses will also provide a comforting ‘hug’ as it adjusts to your body during the night.

The Nectar memory foam double mattress is highly recommended. It’s designed with five layers to ensure it provides the ideal level of support, firmness, and softness.

Latex double mattresses

A latex double mattress is another one of the best double size mattresses available. This is a great option if you’re looking for an alternative material to foam. There are many advantages to choosing this type of material, especially as it’s hypoallergenic and has antibacterial properties. Latex is also just as comfortable as foam and can provide a similar huggable experience. The only downside is that these mattresses are usually more costly.

Hybrid double mattresses

If you’re looking for a double mattress that combines a few materials, then a hybrid double mattress is another one of the best double size mattresses types, as it offers the best of both worlds. The benefit of this type of mattress is that it’s usually engineered with a few layers. These layers usually include gel foam and memory foam, which can provide cooling, increased airflow, and pressure point relief. In addition, there are usually coil springs, which can provide extra lift and support.

Simba Sleep offers a great hybrid double mattress. It has been constructed with five layers, for extra comfort. These include a breathable sleep surface layer which is hypoallergenic, an open-cell foam layer, a unique patented spring-comfort layer, a layer of HD foam with edge support, and a zoned support base. The top layers are designed for breathability and cool benefits and the lower layers offer extra comfort and support. The small double has dimensions of 120 cm x 190 cm. They also offer an EU double mattress, which is 140 cm x 200 cm.

Final thoughts

So as we’ve explored, if you want to find the best double size mattresses to suit your needs, there are many factors to consider. These include the size of your room, your age, body type, height, weight, posture, and favorite sleeping position. Once you’ve decided if you prefer a small double mattress or a large double mattress, then the next step is to choose the best double size mattress for you. Each type offers different benefits like comfort, support, luxury, cooling, or pressure relief. So the best idea is to shop around to find the best double size mattress for the ultimate sleeping experience. You can also check our helpful reviews for more information.
