Small Double Size Mattress: Give your bedroom a comfortable boost

Choosing the right mattress for your needs can be a complex process. Many different factors have to be considered before making the final purchase, which usually takes quite some time if done right.

However, most people would want to buy a bed as soon as possible rather than spending days reading up on the pros and cons of different types of beds or researching their various features.

The most crucial factor in choosing the perfect mattress is knowing what size best fits your needs. Although it seems like a simple task, it’s very easy to end up with one that doesn’t work correctly.

What is a small double mattress?

A small double mattress is just slightly smaller than a standard single. The measurements are 78cm wide by 190cm long, which means that the actual surface area of the bed is only 38% of what you would get if it were a standard size one. This can be considered as being ‘small’ for obvious reasons.

What should I look for when buying this type of mattress?

  1. The main factor to consider before purchasing a small double mattress is whether your room allows you enough space to accommodate it. It won’t matter how comfortable or supportive the mattress maybe if there isn’t enough room in your bedroom for it! The smallest appropriate room width for this sort of bed will measure around 1.35m – although some people prefer to have a bit more wiggle room.
  2. The next thing to consider is weight, as some people are forced to change rooms regularly because of house moves or landlords that won’t allow ‘permanent’ structural changes. Fortunately, most mattresses can be moved around quite easily on their own if this is the case.
  3. Since the mattress will need to fit into a smaller space than usual, it makes sense that you would want to choose one with slimmer proportions. For example, standard double beds tend to have depths of 40-50cm, whereas small double mattresses have 30-40cm measurements. However, there are mattresses available which measure just 28cm deep – so if having the skinniest bed possible is essential for you, you should be able to find one with measurements of this sort.
  4. A lighter bed is easier to transport, but it’s also essential that the mattress is well constructed and doesn’t sag at all when in use. The last thing you want is a sagging surface where you end up feeling stuck in the middle – even if it does make for a very romantic evening!

In terms of standard sizes, small double mattresses must have a width of 78cm and a length of 190cm exactly. If they are any smaller or larger than these measurements, they won’t be classed as ‘small double’ size anymore.

Refine options to find the right mattress for you

If you would like to have a standard size mattress that’s slightly smaller than average, then it’s better to go with one described as ‘extra small double’ or ‘small double.’

Both terms can be used interchangeably, so there isn’t much of a distinction between them. However, it is worth knowing which term retailers will use if you decide to go shopping around in person – since this may vary from store to store.

  1. Type of mattress: The type of bed that you choose will determine how much support and comfort you get from your mattress. For example, memory foam mattresses tend to provide a very high level of support – so if getting a great night’s sleep is essential for you, then this may be the right choice.
  2. Essential extras: It makes sense to consider any particular features or add-ons available with the small double mattress that you like the look of. Suppose it has a luxurious design and comes with all kinds of extra features (such as built-in massage functions). In that case, chances are it would end up being more expensive than an equivalent model without these benefits included.
  3. Comfort Grade: The chart above provides a rough idea of how comfortable each mattress in this section is to sleep on. Based on the research that I have done, Comfort grades A to D are available – with ‘A’ being the most comfortable option if you would like to get very close to the feel of sleeping at home.
  4. Price range: The price range for small double mattresses tends to be relatively narrow compared to other types of beds. Generally speaking, budget models cost just £55-£100, mid-range ones are priced between £100 and £200, and items which are made using high-quality materials cost over £200.
  5. Turnable: There are some mattress models on sale which can be turned over instead of being rotated. Turning the bed will theoretically provide more even wear, and it also increases the life of your mattress as a whole. Most people prefer to turn the mattress every 3-6 months – but if you like sleeping on one side of your body more than another, this may not be an issue for you.
  6. Mattress Depth: Small double mattresses measure between 30 and 50cm in depth, although some come with 28cm or fewer measurements. A standard double bed usually measures around 40 – 50 cm deep, so if having a small gap between the floor and your bed is essential, then it makes sense to buy one with a28cm deep design.
  7. Mattress Firmness: Usually, small double mattresses will feel more firm than a standard size mattress. Part of the reason for this is that people generally prefer to sleep with less space surrounding them – so they will naturally go for a firmer option as it won’t sink in as much as a bouncier foam mattress.
  8. Construction: The height and type of components used to make up your mattress will determine its firmness, price range, how long it lasts, and also how good it feels to lie on top of. For example, if you are looking for a very thin or lightweight bed, it might be wise to opt for an open coil spring design that is often lighter than foam ones (and more affordable too).
  9. Brand: Paying slightly more for a brand that has been in the business of making mattresses for many years can be worthwhile – since they usually use high-quality components (and materials) in their products. This means you will end up with a bed that feels comfortable, supportive, and lasts an exceptionally long time.
  10. Availability: The products listed above only appear on this website, and they may not be available in your local area. However, there is a good chance that they will all be stocked at certain retailers – which means you can go shopping for one of them (in person) if you wish to do so. Just enter the store’s name into any search engine and access its website to find out where it is situated.

Why choose a small double mattress?

People choose a small double-sized mattress for many different reasons. Some of the most common ones include:

1) The bedding measurements in their bedroom are restricted (the current double bed is too big) – so buying a smaller version makes sense.

2) They have a standard-sized single mattress at home and wish to replace it with a twin one instead.

3) They want a little more space when they sleep, so they opt to buy a slightly larger mattress than usual.

4) There is only one person who will be sleeping on the bed, but they’re pretty tall or overweight – so need more room to stretch out.

What types of small double mattresses are there?

There are several different types of small double mattresses available for sale at the moment. These include:

  • Open coil spring – these models come with hundreds of metal springs that are intertwined together to form a firm base. If you want to buy a bed that is lightweight and affordable then this type may be worth considering.
  • Latex – like memory foam, latex mattresses conform closely to the body and they provide great pressure relief (which is what makes them feel so comfortable)
  • Memory foam mattress- also known as viscoelastic or Visco memory foam, these designs distribute weight evenly and displace it over a wide area (so they usually offer great pain relief). They can be quite pricey, however.
  • Pocket sprung mattress- pocket sprung mattresses are also known as zoned springs and they provide excellent support to all parts of the body. They do tend to be quite bouncy, however – which means they may not be suitable for everyone.
  • Hybrid- these beds combine the support of springs with the comfort and pressure relief of memory foam. They are also naturally hypoallergenic, unlike some other types.
  • Air- these models are designed to provide support to the body weight while allowing air to circulate freely around it. This not only ensures that the sleeper remains cool – but also helps to prevent dust mites and other allergens from building up inside the bedding.
  • Waterbed- these designs generally contain a large water tank that the bedding is placed on top of. They are not particularly popular, however – since they are often difficult to set up and maintain correctly.
  • ActiGel®Many small double mattresses (particularly those that are memory foam-based) include ActiGel® – which is a patented gel layer that is designed to provide soothing pressure relief and support under the heaviest parts of the body. It also helps to reduce motion transfer between partners, thereby minimizing disturbance during sleep.

Fiber fillings

Most small double mattresses contain fiber fillings at their core – which adds to their comfort and support. They include:

  1. Pine cones- these provide good airflow around the mattress, which means you will never become too hot or sweaty while you’re asleep on it. In addition, they can soften up quickly when exposed to warm temperatures. However, this type of filling may offer less support than some other alternatives.
  2. Cotton – this material is moderately supportive, but it tends to flatten out rather quickly – which means that the bedding will need to be replaced within 2-3 years as a result.
  3. Kapok – these designs are relatively lightweight and they offer good relief, although they can feel quite coarse against the skin when you first use them. They also have a high ‘bounciness’ factor, which means they tend to move around a lot during sleep.
  4. Hollowfibre – these models provide support for all parts of the body and they are usually reasonably comfortable (particularly if they contain memory foam). However, this type does not always work well with open coil spring designs- so check the specifications carefully before you buy.
  5. Wool – these fluffy mattresses are naturally hypo-allergenic and resistant to dust mites, bed bugs, and other pests. However, they are not particularly supportive, while some models can smell quite strong when you first unwrap them. They are also very heavy and bulky, which means that they may be difficult to transport.
  6. Polyester – this material is reasonably comfortable while it is also relatively inexpensive. However, it tends to wear out rather quickly – which means that the mattress will need replacement after around 4 years of use on average.

Choosing the best small double mattress for you

If you are looking for a small double mattress (also known as a single or twin size), there are some key things that you should consider before buying one:

I. Pressure relief – while most small double mattresses provide good support, they may not offer the kind of relief that larger individuals need. This means it is vital to choose a model with ActiGel® technology, which provides gentle cushioning under the heaviest parts of your body.

II. Motion transfer – if you share your bed with a partner, it is important to look for a model that minimizes motion transfer between you both. In this case, models with individually wrapped springs and memory foam tend to work best – since they absorb momentum when one person moves around.

III. Firmness – different sleepers prefer different degrees of mattress firmness in their bedding, so it is important to find a model that matches your personal requirements. If you are an average-weight sleeper, an all-foam design should work well for you.

  • Soft mattress: A soft mattress is generally recommended for comfort, although this kind does not provide much support. In addition, a soft bed needs to be handled with care as it can sag under the weight of a heavier sleeper over time. If you choose a model that has a pillow top instead of ActiGel technology, you will need to flip and rotate it regularly – so an inner core with high-density polyurethane foam may work better for you in this case.
  • Medium-firm mattress: A medium firmness offers better support than a soft design while it remains comfortable as well. In general, this type is suitable for average-weight individuals who want as much relief as possible from their new purchase. However, someone who weighs more or who has broad shoulders and hips should consider an all-foam model instead.
  • Firm mattress: If you are looking for a bed that provides the most support, then you’ll need to choose an option with at least some level of firmness. However, this type is often less comfortable than any other – particularly if it has no pillow top or ActiGel technology. As a result, it may be best used as a guest bed or for children rather than by an adult sleep partner.
  • Extra-firm mattress: Finally, extra-firm mattresses are usually the best choice for those who weigh over 200lbs/90kgs (or couples who prefer different degrees of firmness in their mattress). However, they tend to provide the least amount of comfort of all – so it is wise to choose one with ActiGel or high-density reflex foam technology if possible.

However, if you weigh significantly more than this or if you have particularly broad shoulders and hips, then the best choice may be one with individually wrapped springs instead.

Finally, always check the return policy before making a purchase – since mattresses can feel very different once they have been removed from their packaging and inflated fully.

Sleeping position

The best small double mattress for you will depend on your sleeping position, as well as your personal preference for firmness.

  • Side sleepers: If you sleep mostly on your side, a medium-firm to firm bed is generally recommended. In this case, models with individually wrapped springs tend to work best as they relieve pressure as well as any all-foam alternatives.
  • Stomach sleepers: If you prefer sleeping on your stomach, it is vital to choose a mattress that keeps your spine in a neutral position – particularly if you have broad shoulders and hips. In this case, an all-foam model or one with ActiGel technology will be more suitable for you
  • Back sleepers: Sleeping on your back is the healthiest choice of all – but some mattress types can make this difficult. Depending on how sensitive your spine is, choosing a firm or extra-firm version with ActiGel technology may be the best choice for you.

Can a small double mattress fit two adults?

Most small double mattresses can fit two average-sized adults in them – although this will depend on the mattress itself. For example, many models offer separate support for each sleeper (such as individually wrapped springs or memory foam layer), meaning that they are much more suitable for couples than less expensive single-size designs.

However, if you do not require extra support under your body while you sleep, it may be better to invest in a larger bed instead of buying individual parts separately. This is because many standard double size options tend to be somewhat wider and longer than most small doubles – so if both people want to stretch out fully at the same time, it can often feel rather crowded indeed.

Can a small double mattress fit on a double bed?

It can be difficult to get a small double mattress onto a standard double bed base – especially if the frame is particularly low. If you are buying online, it may be better to choose one that comes with its own storage bag or box (from reputable brands such as Sealy), so that you can transport the new item easily once it has arrived at your home.

There is also some debate about whether you should let the air out of the soft knit cover when transporting it in this way – since some sleeping surfaces are more likely to lose their shape when they are deflated for any length of time.

What is the difference between a British and an American mattress?

The main difference between British and American mattresses is that the latter tend to be wider and longer than their UK counterparts. This means that they are better suited for two average-sized people sleeping side by side (although you may still feel a little crowded if both of you try to stretch out at the same time).

On the other hand, British models are much narrower – which makes them ideal for single sleepers who want plenty of space to spread out on their own. They also tend to have firmer densities as well as very thick pillow tops, so they feel more luxurious underfoot while offering good support as well.

British mattress sizes

British mattress sizes are based on the length of the bedding – rather than the width. This means that a single model is 3ft wide by 6ft long, while a double version will measure 4ft wide by 6ft 6″ in size.

  • Single- designed for a single adult, the standard size mattress has a length of 3ft and a width of 90cm. It is suitable for anyone up to 5’6″ in height by this point.
  • Small double – which can fit two average adults side by side if they are around 5’10” tall or shorter each. This option measures 4ft wide by 6ft long – as well as being just 15cm deep from front to back.
  • Double – designed for couples who want the room to stretch out without feeling cramped next to one another, this version also suits those who are slightly taller than average (at around 6ft) as well. It measures 4ft wide by 6ft long – but it is 20cm thick from front to back.
  • King size mattress – at 4ft wide by 6ft long, this type of bedding is best for those who are over 5’11” tall, as well as couples who prefer a lot of space to spread out in. It measures 20cm from front to back and has a depth of 25cm.
  • Super-king – which is ideal for taller couples, especially those who are over 6ft 1″ tall. It measures 4ft 3″ wide by 6ft long and has a depth of 30cm.

American mattress sizes

American bedding sizes are based on the width of the mattress, rather than its length. This means that a single American model is 3ft wide by 6ft long, while a double version is 4ft wide by 6ft long.

  • Single- again suited to adults up to 5’6″ in height, this size has a length of 3ft and a width of 30 inches. It is around 60cm deep from front to back as well.
  • Small Double – which measures 4ft wide by 6ft long and 15cm from front to back. It can comfortably fit two sleepers who are shorter than average (at around 5’10”) as well as those who are slightly taller (up to around 6ft).-Double – which has a length of 4ft and a width of 40 inches, or around 100cm. This bedding is suitable for couples who are under 5’11” tall as well as those who prefer more space to stretch out on.
  • King size mattress – this type of bedding offers a good level of comfort to sleepers who fall within the average height range (i.e. 5’8″ to 6’0″). It will measure 4ft wide by 6ft long and it is 60cm deep from front to back as well.
  • Super King – which is ideal for taller individuals as well as couples who prefer lots of room while they sleep. It measures 4ft 3″ wide by 6ft long, or around 120cm in width. It is also 70-75cm deep from front to back.

Which mattress size is best for children?

Unlike adult bedding, child mattresses can often feature detachable sides, meaning that they are easier to handle in the case of multiple changes or if you need to travel with them.

There are also certain models with adjustable heights, meaning that they can be used by children of all ages – rather than simply being discarded after a few years.

Finally, one thing worth considering is how long it will take you to get into and out of bed each night – since this often affects the overall lifespan of your mattress.

Scrambled eggs can take up more time than other styles when getting dressed in the morning, while pinstripes work well if both partners rise at around the same time each day.

What’s the Difference Between a Double Bed and a Queen Bed?

Although a double bed is the same width as a queen bed, it isn’t quite so long. In terms of length, a double measures 5ft 6″ compared to the 6ft of a queen.

Also known as Eastern or Eastern King-sized bedding, this type is designed for taller sleepers who want more space to stretch out on when they’re lying down. It also offers couples an excellent level of comfort since there’s enough room for both partners to have their own personal space.

What Is Best Mattress Size For A Toddler?

There are lots of different mattress sizes available for children, making it easier than ever before to find the right one for them depending on their age and whether they are sharing with another child or not.

  • Mini or small single bed – this is one of the most versatile sizes available since it can be used by toddlers who are around two years old and up until they reach four. It measures 3ft wide by 6ft long and is designed to be easy for young sleepers to maneuver in their own bedroom.
  • Cot size mattress – if a little more space is required, a child’s cot mattress will work well. These measure at around 4ft wide by 6ft long and come with an adjustable base so that they can grow with your child.

Caring for a small double-sized mattress?

It’s important to check the label of any mattress you buy to ensure that it is suitable for your bed frame and intended purpose.

If buying a pocket sprung or memory foam type, make sure that the number on the box matches the one printed on your small double-sized mattress – since different models can vary in terms of depth and density.

For example, some will be 25cm thick while others might be only 20cm or 15cm deep. Allowing around 5-6 centimeters (2-2.5 inches) between your box spring and mattress will help reduce wear and tear over time as well as ensure that dirt doesn’t build up inside them.

Where should you buy a small double-sized mattress?

There are lots of places to buy small double-size mattresses. If you want to see your bedding before you buy it, shopping at a local store is often the best idea – since you can try out different types and sizes in person before selecting the one that will work best for you.

However, this doesn’t mean that buying online won’t be worthwhile as well – especially if you are working on a tight budget or want to save yourself some time.

Buying new bedding of any kind can be expensive, but it’s worth keeping an eye out for special deals and discounts wherever possible.

How do I choose a double mattress?

When choosing the perfect mattress for your needs, there are several factors to take into account including what type of sleeper you are, how much space you have available, and even who sleeps in the bed with you.

If you’re sharing, it’s ideal to choose one that is recommended for two people – but if you’re buying for yourself then a standard double will be fine unless you are planning on sharing the bed with someone else or prefer more room when lying down.


A small double-sized mattress is suitable for anyone who wants more space to stretch out on when they’re lying down. It also offers couples an excellent level of comfort since there’s enough room for both partners to have their own personal space.

There are lots of different mattress sizes available for children, making it easier than ever before to find the right one for them depending on their age and whether they are sharing with another child or not.
