That’s why the importance of having not only the best mattress but also the best bed-sheet, the best toppers with the best pillows within your affordable limit to get the best possible sleep daily, can never be overstated.

Doctors, researchers, and scientists alike have long agreed that sound sleep has a profound effect on preserving our mental and physical health. And a quality mattress can increase the probability of our sound sleep manifolds. Also, our beds should be a welcoming retreat, from the day-long din and bustle we have to endure, so that we can enjoy our much-needed sleep, to start the fight all over again from the next morning.

Today I am going to discuss the different dimensions of the mattresses available.

Size may not matter for many things in life, but for mattresses, size really does matter. Mattresses come in different sizes and shapes, and every one of them has their places in various stages of our entire lifecycle. All you need to know about mattress dimensions

Toddlers/Crib 28“ X 52“ 2.33`X 4.33` 1456 Sq In./10.08 Sq Ft One Toddler

Let’s get to know about the dimensions of each type of the mattresses a bit more in detail:

1. King – 76“ X 80“:

There is a reason for calling this mattress ‘King.’ If you are an average-size person, which most of us are, the ‘King’- sized mattress will make you feel royal. It is generous in space, and even when you share it with your partner, it gives you the luxurious feel of belonging.

King – 76`` X 80`

It is the mattress considered as the best for couples. If you value your personal space even when you are sleeping, this is the mattress for you. On the other hand, for movie-nights on the weekend, this is the perfect voluminous surface for making the whole family cuddling and snuggling with comfort.

The ‘king’ is the best option for ‘active’ sleepers with partners. Since there is more than enough space, you can dawdle, straggle or wobble all you want without ever causing trouble for your partner, who might be a light sleeper. Also, you can lie down late and get up early without disturbing your partner’s sleep.

If your purse is deep enough to splurge and your bedroom is large enough to accommodate, this is the best mattress you can reward yourself too. Many people feel it is worth every penny since it is going to determine the quality of your sleep for many years to come.

But don’t start rushing yet for getting it to your already strangled bedroom! Can the ‘king’ even fit in the room? Are you planning to change your present address shortly? Think about these and then decide between buying one.

2. California King – 72“ X 84“:

California King is the most extended member of the mattress family, having a length of 84 inches. If you were one of the stars of your championship-winning NBA School Team and had your feet dangling outside the bed since you were 12, this is the bed custom-made for you – and also for all the other tall people around the world.

California King – 72`` X 84``

It is also known as the Western King. The makers have shed 4 inches of width while increasing the length by the same measurement. This tweaking reduces the total surface area by a mere 32 square inches, which still provides ample space for the parents to sleep with the toddler on windy, thunderous nights comfortably.

This is also a fantastic mattress to sleep on for the active tall couples. And all the benefits of the King mattresses are there while paying a fraction short the amount you would be paying for the King. Again the usual assortment of considerations still needs to be considered before buying this item for your abode. But if you are on the north of 6` and don’t want to refute the necessity of sound sleep, you are going to have to make arrangements to have it in your bedroom.

3. Queen – 60“ X 80“:

This is the darling child of the family as most people use it for their resting place. It provides space without sacrificing versatility. It offers comfort but, at the same time, can be fitted in any reasonably erected bedroom. This mattress offers ample square inches for comfortable, deep sleep instantly.

It also lets the couple sleep with their furry friend, who tends to be in the shorter periphery. It can also make the stormy nights into story nights, and the toddlers with their favorite pets can enjoy the adventures in mom’s soothing voice.

As I have mentioned earlier, any reasonable erected bedroom can have it, and still, there will be space around to have more furniture. This is one of the reasons in most hotel rooms, living rooms, and guest rooms are furnished with it. This aspect turns it into the best seller among other mattresses. But it is also one of the cost-effective compared with other mattresses in terms of value-for-money angle.

Queen mattresses aren’t ideal for children. It might also be a problem for couples if both of them are hyper-active sleepers. Sometimes it can pose a challenge for the studio apartments, where there won’t be much space left after you set it up, or if any, for that matter.

But for being superbly suitable for most bedrooms, efficient in cost-effectiveness and comfortable enough for most couples – the ‘Queen` is the ‘gold standard’ of mattresses today.

4. Full/Double – 54“ X 75“:

The name here suggests ambiguity – this is a mattress for a singular person who likes to – like I’ve said earlier – dawdle, straggle or wobble. Single sleepers love it as there is more than enough width they can ask for. It is profoundly suitable for teens and single adults until they change their relationship status. But for adults who are on the taller side or for the teens that are getting taller a foot a day, this isn’t a match ‘made in heaven.

FullDouble – 54`` X 75``

The Full/Double-sized mattresses were the pick of the choice before the ‘Queen’ took over. As the width suggests, a couple might just fit in, given that they sleep like robots or they don’t mind cuddling, snuggling even after they fall asleep. Another noteworthy compatibility for Full/Double mattresses is that for being compact, they are an excellent fit in RVs. That makes them an automatic choice for the couple who love camping or moving around the country with their mobile home.

Another cuddly selling point for this mattress can be that the mom can tuck-in with the child-friendly and comfortable in the bed in time for bed-time stories. 

So it is the perfect fit for kids, teens, average height single adults – but maybe not so for couples and taller people.

5. Twin – 39“ X 75“:

As the size shows, this is the smallest among the standardized mattress sizes. This size is designed only for a single sleeper of average heights. The surface area of 2925 square inches doesn’t necessarily render a spacious void to sprawl freely.

In other words, if your body moves too much while you are asleep, this is not the right size for you. But it is a great tool to equip a teen’s room, and also it is considered as the best bunk-bed mattress. So, it can be used efficiently as a space-saver when the siblings share the same bedroom. 

For students who live in the dormitories or arrange accommodation privately outside the campus, this is the perfect mattress to sleep on after long days on the campus. Although you can be forgiven if you ask when or if ever the students use the mattress for sleeping, that’s just another mystery of God’s green earth.

Let’s move on and think about another practical use for the young, upcoming professionals who are just starting their careers. This demographic can easily use it as the Twin mattresses can be moved easily. Just tie it over the beat-up van and start the journey.

The best way to define it is the mattress, which helps people who are in perpetual transition –the teens move towards adulthood, the students have their eyes in the careers up ahead, and the young professionals dream about the next best gig to earn serious money.

6. Twin XL– 39“ X 80“:

Every benefit and every drawback of the Twin mattress gets about 10% revamped when you get the Twin XL mattress. The height for this mattress is increased by 5“ which may not sound drastic enhancement, but it can make the difference between the feet dangling or not. Like I’ve just said, this mattress can be an excellent fit for a bit taller individuals with non-active sleeping habits.

The transitory demographic, like the teens, the students, or the young professionals, get to their destined height when they are about 20-22 years of age. So, the ingenuity of the idea to increase only the height by a mere 5“ serves them most – that’s the thing I love most about this mattress. And luckily, the mattress makers don’t raise the price too much, so it is economically cost-efficient as well.

7. Crib/Toddlers – 28“ X 52“:

The Crib is best suited for the first 18 months of the newborn. A perfect crib mattress gets stuck perfectly inside the frame that is designed to hold the mattress strongly. The mattress is also a bit on the firmer side, which eliminates the chance of breathing hazards for the baby. The finishing of the Crib with perfect bedding requires extra care.

As it is pointed out by the experts, for the first 12 months of their life, babies should have only the tight-fitted bed sheet over the Crib and nothing else. The mattress might get dampened by diaper-drippings or with some other messes, that’s why parents often use waterproof over the bed sheet or antimicrobial sheets. Sometimes the crib mattress is made as breathable to control the temperature. A few Crib mattresses often have two sides – the firm one for the babies and the softer sides are for the toddlers.  

When the babies are 18 months old or more, the walls surrounding the Crib are removed, and it becomes a mattress for the toddlers. The mattresses for the toddlers are made differently than the crib mattresses. The Crib mattress is firm, while the Toddlers mattress is soft. Toddler mattresses are no longer surrounded by walls, though some parents put in small railings as preventive measures so that the toddler cannot get out of the bed on their own.

Usually, parents let their children sleep on the toddler’s mattress until the age of 4 or 5. The mattresses are small, easy to move, and an excellent option for small rooms. Some parents save money by not opting for Toddler mattresses. They keep the Crib mattress given that its condition doesn’t get deteriorated too much and choose twin mattresses when the child becomes 4-5.

There you go. Now you know everything about the mattresses! But how would you decide which size is the best for you?

Thoughts before Making the Final Decision:

Thoughts before Making the Final Decision


Before going to the store physically or visiting online outlets, get to the bottom of the following questions with care:

  • How spacious is your bedroom?
  • How much space would you love to have after the mattress takes its place?
  • Do you need furniture to throw out of the room for the new mattress to fit in?
  • How important is it to have space left on both sides of the mattress?
  • Can you physically be able to get the mattress in the room?
  • Are you planning on moving anytime soon?

The answers to the above questions, the knowledge about you being an active sleeper or not, and the depth of your purse – coupled with the things you have learned from the above discussion – you should be capable of making an informed decision to complete the purchase.

If you need to know about Mattress history

Now all you are left with is sleep.

Sleeping Tips to Help You Fall Asleep Fast.Kimberly Fenn, the Associate Professor of Psychology and the Director of Michigan State University’s Sleep and Learning Lab, has recently said,

“Our research showed that sleep deprivation doubles the odds of making place keeping errors and triples the number of lapses in attention, which is startling. Sleep-deprived individuals need to exercise caution in absolutely everything that they do, and simply can’t trust that they won’t make costly errors. Frequently — like when behind the wheel of a car — these errors can have tragic consequences.”

The truth is, without even knowing the wise words of the professors, we, the general population, should at least feel the effect of sleep deprivation firsthand. The pressure we have to absorb and the stress we have to go through on a day-to-day basis sometimes amount to colossal mental bearings. And when we go to bed to sleep, all that has gone on won’t let us sleep. Another thing is, not only outside pressure of living in a modern, fast-track society, and some people are born with sleeping disorders with problematic genomes.

Whatever the reasons that are not letting you fall asleep fast, you are not alone. Please keep reading to get a few ideas with which you might not have been familiar with:

The temperature of Your Bedroom:

The temperature of Your Bedroom

As we fall asleep, there are changes happening in our body temperatures. The temperature at the core of our body decreases, but our hands and feet experience the rise in temperatures.

So it is pretty obvious that if the room where you sleep at night is warm, you will have difficulties in falling asleep. The sleep-inducing ideal temperature would be something like this – 15–23°C or 60–75°F. We all have different preferences, so find out which temperature suits you best and stick to it.

Another cool way which I am sure most of us are already familiar with is to take a hot shower. After the shower, our body lets the heat out of the system, and our brain starts preparation for the much-coveted sleep. As a result, the signal might come running as soon as you lay your body down over the best mattress that you have invested in, especially for that to happen.

The Breathing Mode: 4-7-8

It’s easy, it’s simple, and it doesn’t cost anything. All you have got to do is do it regularly.

It is well documented that the “4-7-8” breathing-method instigates tranquility, which helps you unwind your stresses, at least for the day, and make you relaxed.

I am sure people with problems falling asleep fast know all about it. But those who don’t know this powerful method, please read the process carefully:

Sleeping Tips to Help You Fall Asleep Fast

Here it goes:

Position your tongue, only the tip of it, just behind the teeth that are on the upper front side.

Next, you have to breathe in, but you need to do it using only the mouth without ever using the nasal path. After taking a breath, make a sound so that you can hear something like ‘whoosh.’  

After that, you have to close your mouth and take the breath in through the nasal way while counting one to four in your mind.

Then hold your breathing and count one to seven in your mind.

The last bit is opening your mouth and exhaling all the air out. Again it would help if you made the gentle noise sounding something like ‘whoosh’ and count up to eight in your mind.

Just repeat everything a minimum of three times.

This technique can relax you and help you fall asleep quickly.

 Live Your Life through a Timetable

Live Your Life through a Timetable

Again I am not going to say anything new, but it is so essential that it is worth repeating many times over.

When you are organized and follow a timetable, your regulatory system, which is called a circadian rhythm, get accustomed to it subconsciously. As a result, the clock within your bodily system will have the brain sending signals at the right time. So, you will be on your toes during the day and start feeling sleepy as the time approaches.

That’s why getting up and going to bed at the same time every day will regulate your internal clock to work its magic. Maybe you need to struggle for the first few days if you have just finished your studies and started a regular job. But with time and effort, your body will get in line, and your mind will act accordingly.

One important habit of falling asleep fast is making a wriggle room of about 30 minutes to loosen before going to bed. This will de-stress your mind and preparation will be started within.

Get the Sun and the Dark

Bright light – be it the shining sun or from an artificial source – auto-regulate the inner clock your body possesses. The exposure to light makes you lively, and the lack therein prompts your sleepiness. So it is imperative that you expose yourself to bright light regularly. This will embed your circadian rhythms to fall asleep soon after you rest your head on the best pillow you have awarded yourself.

On the other hand, darkness induces sleepiness. Research also tells us that the production of melatonin – the essential sleep hormone, is boosted by darkness.

So during the daytime, get ample light and, when at the time of sleeping, embrace total darkness.

Do Yoga, Practice Meditation and Grow Mindfulness

Do Yoga, Practice Meditation and Grow Mindfulness

As I have mentioned earlier, stress prevents us from sleeping fast.

The best weapons to deal with stress are Yoga, meditation, and mindfulness. These instruments help us fight stress. They won’t make our problems go away, but they will help us not worry about them all the time.

Yoga improves breathing and promotes fluid body movements that fight off by stress removing all the tensions accrued. Melatonin levels can be enriched by meditation, and mindfulness keeps our focus. All these enable us to deal with stresses, which in turn will let us fall asleep faster no matter where we sleep – be it on the best bunk bed mattress or the California King.

 Sleeping In the Daylight? Be the Researcher of Your Own Study

Sleeping In the Daylight Be the Researcher of Your Own Study

Frequently insomnia causes poor sleeping experience at night, which makes the insomniac napping during day time.

Though the ‘beauty sleep’ during the afternoon is said to have a positive effect on being attentive, experts are divided in opinions about the benefits it is supposed to render.

There are many studies to show for each side of the argument, but I believe it would be best decided by you. Common sense would be not sleeping at all during day time or limiting the duration to a short span like a mere 30 minutes.


 A Few More Ideas That You Probably Know

 A Few More Ideas That You Probably Know

Let me give you a few more tips about how to fall asleep faster without elaboration. Just try to be attentive about them, practice, and in time they will be second nature:

  • Eating the Right Foods at the Right Time
  • Listening Music That Relaxes Your Nerves
  • Physical Exercise
  • Turning off The Electronics before Bed-Time
  • Maintaining a Log Book
  • No Caffeine after the Sunset
  • Readjust Your Sleeping Position
  • Reading before Sleeping
  • Visualizing Things That Make You Happy

I sincerely hope the above tips will help deal with your sleeping problems.

So sleep tight and stay well.
