How many inches a mattress should be depends on the sleeper’s individual requirements and preferences. We’ll go through how thick a typical mattress is and whether you should choose thinner or thicker. The thickness of your mattress has an effect on your sleep much like the headboard does.

We’ll also go over mattress dimensions like height and length to make sure you get the best possible sleep. In that case, why delay? Just keep scrolling down and you’ll soon be drifting off to dreamland.

5 Benefits of A Good Mattress

1. Achieve Adequate, Quality Nighttime Sleep

The major benefit of a good mattress over a bad one is that you always get a decent night’s sleep or nap. Mattresses might make you feel like you’re sleeping on a cloud, depending on the sort you get. This comfort could come from alleviation from pressure points in the body or from the support of your back.

Your mattress, if it’s any good, will facilitate rather than disrupt your slumber. You may need a new mattress if you’re constantly uncomfortable, have trouble falling asleep, or wake up in agony. If you suffer from persistent back pain, go here now to read about the mattresses doctors suggest most.

2. Promote Good Form and Posture

People tend to sleep in a variety of postures, some of which they may not even be conscious of. Maintaining or enhancing your shape and posture is possible with the help of the correct mattress. If you sleep in the same position night after night, you need a mattress that supports that position.

For example, those who sleep on their sides are more likely to experience back pain because the fetal posture increases pressure on the spine and neck. Since it will be forced against the mattress, it might also exert pressure on the arms and shoulders, cutting off circulation. If you favor sleeping on your right side, you should know that this puts extra strain on your internal organs.

Memory foam mattresses, thankfully, have you covered if you sleep on your side. The responsiveness of the material helps to keep the spine in its natural position and cushions any pressure areas. But if you choose a mattress that isn’t good for side sleepers, you could be putting stress on your spine and joints. Consider your preferred sleeping posture before making a purchase.

3. Keep Your Mental and Emotional Health in Check

The quality of your sleep might be severely disrupted by a mattress that isn’t up to par. Sleeping on a terrible mattress every night can lead to sleep deprivation and fatigue, even if it simply causes insomnia at first. Sleep deprivation is associated with a number of negative outcomes, both immediate and long-term, and can have a significant impact on your mental and emotional well-being.

Some of the most prevalent negative impacts of insufficient sleep on one’s mental and emotional health are as follows:

  • Idleness and lack of focus and awareness.
  • This condition results in daytime sleepiness and excessive yawning.
  • Increases irritation and changes in mood.
  • Disorders of the mind such as anxiety, depression, bipolar, and ADD are made worse (ADHD).
  • Reduces mental efficiency and productivity.

If you have a nice mattress, you’re more likely to get a restful night’s sleep and less likely to suffer from the health problems we just discussed. To get the finest sleep, though, a comfortable bed alone isn’t enough.

4. Develop an Inclination to Your Sleeping

Unfortunately, a terrible mattress is just one of the numerous individual factors that might contribute to someone’s chronic insomnia. Some people are so busy with their hectic schedules of work, school, and extracurricular activities that they neglect to get enough rest. You may be able to get your sleep back to normal once you invest in a high-quality mattress.

If you’re not feeling refreshed in the morning, your mattress could be to blame. Creating a relaxing bedroom setting can also help you get more shut-eye.

It’s important to give yourself the gift of a good night’s sleep every once in a while. Here are some suggestions for creating a restful environment in your bedroom:

  • Sleeping and personal moments should be reserved for the bed.
  • Reduce background noise and other potential interruptions.
  • It is recommended that the temperature in the room be reduced to 65 degrees Fahrenheit (18.3 degrees Celsius).
  • Do not place any electronic devices within reach.
  • Simplify the visual presentation as much as possible.
  • In the bedroom, go for warmer, softer tones.

5. Get the Most Out of Your Purchase

The current market price of a mattress is not funny. Mattresses, even the cheapest options, might be tough to save for if you already have a lot of other bills to pay.

A good mattress, therefore, is an investment that should last a lifetime. High-quality mattresses can last for several years with proper care, so you can get your money’s worth out of them.

Compare the typical durability of different mattress materials:

  • Five to six and a half years is the typical lifespan for an innerspring.
  • 6–7 years for foam
  • Latex: 5–8.5 years
  • 5–7.5 years for a hybrid vehicle

How Many Inches Should A Mattress Be And What’s The Best One For You

The thickness of mattresses sold commercially can vary from 8 inches to 14 inches. Knowing the optimal layer thickness is crucial. Learn about the different layers of a mattress so you may customize it to your comfort level.

The recommended thickness of a comfort layer is 3 inches, whereas the recommended thickness of a foundation layer is 8 inches. And the transition layer needs to be an inch or two thick. Keeping these dimensions in mind will guarantee a bed that is both soft and supportive, as well as long-lasting.

Does thickness affect durability?

The topic of whether or not you should always choose for the thicker mattress may arise. Does more thickness also mean greater longevity? It’s reasonable to infer that durability improves with base thickness.

Doing so makes logical, since it will help the mattress retain its form over time. You should look for a mattress with a foundation layer at least as thick as your desired sleeping surface. Keep in mind, nevertheless, that you need still choose a mattress with the right thickness for your sleeping position.

What to get for your sleeping position?

Mattresses of 10 to 12 inches in thickness are recommended for those who sleep on their backs, while mattresses of 14 inches in thickness are appropriate for those who like to sleep on their sides. The opposite is true for stomach sleepers, who need only utilize a mattress no more than 10 inches thick. These are the recommended dimensions for each sleeping position to keep your spine in a neutral state.

Memory foam, for example, functions best at a thickness of 10-14 inches. Utilize the shape-retaining properties of the foam to their fullest extent and rest assured that it will hold up well over time. If you pick a less robust material, it could sag in as little as three years.

Mattress Thickness: How to Choose the Right One

How thick should your mattress topper be?

Since we’re discussing the optimal thickness of a mattress, we might as well go over the same information for a mattress topper. If you want to change the softness or firmness of your bed, you’ll need a mattress that’s at least 2 inches thick. However, a 4-inch topper may be more preferable for some users, especially when only a temporary fix is needed for a dented bed.

Should I Get An 8 Inch Or 10 Inch Mattress?

The most important thing to remember is to order a mattress with a thickness that suits your specific demands. In contrast, an 8-inch bed is often contrasted with a 10-inch bed. Consumers face this conundrum frequently when looking for a new memory foam mattress.

As we briefly covered previously, something with a thickness of at least 10 inches is recommended. When you lie down, the foam will be able to take your weight without giving way. Thinner options may not provide the same sense of stability, and they distort more quickly.

What Is Normal Mattress Height?

There is a wide variety of mattress heights available, often between 16 and 24 inches off the floor. Nonetheless, why is this such a crucial consideration when purchasing or arranging a bed? It can, for one thing, make it more difficult to get in and out of bed.

Beds that are lower to the ground are helpful for persons who have trouble rising from the floor, such as the elderly or those with mobility issues. Sit on the edge of the bed and make sure your feet are flat on the floor to determine if it is the proper height for you. Similarly, your knees and hips should be in line with one another, with your knees never crossing over your hips.

But if you have to have a certain mattress thickness, you may always modify it to get the best fit. If you absolutely must sleep on a thick mattress, for instance, a short bed frame is the way to go. Instead, if you like a thinner mattress and a taller bed frame, go with the latter.

How Long Should My Mattress Be?

The appropriate length of a mattress is subjective and hence impossible to quantify. But we have a helpful hint: make sure it’s at least six inches longer than you are. Make sure you can easily put both your hands behind your head if you sleep with a partner.

Depending on the dimensions of the room, your length may also be restricted. Make sure you have plenty of room to move around in the bed.

How to Keep Your Mattress in Good Shape Longer

We have compiled ten of the most effective methods for safeguarding your mattress investment through proper maintenance and the avoidance of potential catastrophes.

1. Make sure your mattress is properly supported.

It’s important to make sure your mattress has the correct amount of support, and while you might not necessarily need to buy the matching box spring or foundation, it’s still a good idea if you can. This aids in maintaining materials and putting off wear and tear.

For suggestions, you can either contact the maker or read the guarantee. Memory foam mattresses and other speciality mattresses typically demand strong, stable support, hence box springs are typically exclusively utilized with spring mattresses.

Queen and king size beds particularly require center support bars to ensure they can hold the weight of their occupants and the mattress. Depending on the type and weight of the mattress, a bed frame with large slats may be required for a platform bed.

Every year or so, you should inspect the slats and springs supporting your bed to make sure there are no breaks that could compromise the integrity of your mattress.

2. Use a mattress protector from the beginning.

One of the greatest and easiest ways to extend the life of your mattress is to use a protector, and we’ve already discussed why that is.

A high-quality mattress cover not only keeps your bed clean and free of dust, debris, and grime, but is also waterproof in case of an accident.

This prevents allergens like mildew and dust mites from accumulating on your bed, preventing skin oils and sweat from damaging the bed’s components, and makes it more comfortable to sleep on. Many modern protectors are as comfortable as a fitted sheet while still providing the added benefit of being easily washable.

3. Wash bed linens regularly.

Sweat, oils, hair, and dead skin cells are all shed during sleep. Crusts from a late night snack and furry friends’ footprints are just two sources of potential mess left behind after a meal in bed. All of this, aside from being gross, can permeate the various layers of a mattress, providing a fertile environment for bacteria and dust mites.

Most cleaning professionals agree that washing bed linens once every seven days is sufficient. Despite utilizing a mattress protector, regular laundering of bed sheets and pillowcases is recommended. The mattress protector should be washed on a regular basis as recommended by the manufacturer.

4. Get pets separate beds to snuggle in.

If you’re concerned about what might be hiding in your covers, consider buying your pet a bed of its own.

Even if you take your pet to the groomers, it will still come in contact with the outside air, drool, and shed hair and cells just like you and everyone else. A mattress is almost completely ruined by even one mishap from a pet.

5. Rotate the mattress regularly.

Regular mattress rotation is recommended for all mattresses, regardless of size or construction. Though not all manufacturers recommend it, rotating can help ensure your tires wear evenly and prevent depressions or soft spots.

Beds should be flipped from head to foot every 2-4 months. For the first few years while the mattress settles in, this is crucial.

6. No jumping on the bed!

Your mom was right when she cautioned you not to jump on the bed. Although spring, water, and air mattresses are more likely to be damaged by rigorous use, foundations, frames, and foams will all wear out more quickly under heavy stress.

7. Take care when moving your mattress.

Avoid creases and tears by encasing your mattress in plastic before you move. The mattress can be protected from dust, water, and scratches by using a heavy-duty mattress bag, which can be purchased at most moving and box stores and sealed shut with tape.

It is recommended that mattresses be moved while standing on their sides to prevent folding or sagging. Even though some mattress covers have handles for easier transportation, it is not recommended that you use them to drag or move your mattress.

8. Don’t bring home unwanted hitchhikers.

Infestations of bedbugs may quickly destroy a mattress, and getting rid of them can be a major hassle.

Always check for bed bugs and try to avoid sleeping with your luggage on the floor when you’re away from home. Bedbugs are a serious problem, and if you think you’ve seen one, Texas A&M University offers some advice on how to keep them from coming home with you.

If you live in an apartment or section of the country where bedbugs are a problem, you might want to invest in a mattress encasement. Unlike mattress coverings, these completely encase the mattress, leaving no gaps for bugs to hide.

9. Let the light in occasionally.

When there is a dry, sunny day once every two months, take your mattress out into the fresh air and let it sit for a few hours (though if bedbugs are possible, leave the cover on).

According to research conducted at Kingston University, this helps avoid moisture problems caused by both sleepers and humidity, and it may also help control dust mite populations.

10. Follow manufacturer cleaning directions.

Regular cleaning of any mattress is recommended for both the health of the sleeper and the mattress itself.

Most beds should be vacuumed with a hose attachment to eliminate surface dust, and many manufacturers provide guidelines for removing stains and cleaning in general.

Spot-treat stains with a moderate water and soap solution, but let them dry fully before you make the bed. Harsh chemical cleaners should be avoided on foams since they compromise foam integrity.

Vacuuming should be done once every few months or more frequently if there is a lot of dust, someone in the house has allergies, or it’s just preferred.

Mattresses of varying types and brands may require slightly varied approaches to care and maintenance, but the fundamentals are same across the board. The bed should be kept clean, guarded from harm, properly supported, and rotated to provide even wear.

There are a lot of variables that affect how long a mattress will last, but if you follow these guidelines, you may maximize the amount of time you spend sleeping soundly and the amount of money you save. Know that a 10-year guarantee on your mattress is regarded industry standard, whether you’re shopping at a traditional brick-and-mortar store or one of the new bed-in-a-box mattress providers.


Always think about the thickness of a mattress when shopping for a new bed. What is the ideal thickness for a mattress? Each layer of a mattress is important, as we’ve established.

Investing in a substantial foundation will pay off with years of reliable stability. A 10-inch mattress is recommended for maximum comfort and support on mattresses such as memory foam. When using this guide, did you find it helpful?
