I hope you get the basic idea about the common types of bunk beds. Now you can easily understand how many forms of bunk bed springs are available in the market and which one is appropriate for you. Selecting the best box spring mattress will be easier if you know about it.

Mattress Type

Plenty of variations of mattresses are available in the market for use with the bunk bed. You may be confused about what kind of mattress is best for bunk beds. Do not worry, here we are going to introduce all varieties. These are:

* Memory foam:

Memory foam mattresses use a polyurethane foam that contours your body during sleep.

* Gel:

As the gel foam uses soft gel-infused foam, it is super soft.

* Pillow top:

Any materials can use for making pillow top mattress. It has an extra thin layer made of pillow-like upholstery on its head; that’s it named pillow top.

* Innerspring:

As innerspring mattresses are the most durable, it is highly considered the best choice for kids. Some particular types of spring used as padding for maintaining the support system. Among the different types of mattresses, only the innerspring can hold their shape correctly.


A latex foam mattress feels like plastic because they are a little bit stiffer than others.

The thickness of the mattress

As we already discussed that the bunk beds are a little bit different from other traditional beds. So, it would help if you are very careful to select the right mattress for it. Your mattress should not be too thick because if you compare it with other beds, it is relatively shallow.

The best pick for bunk bed should be within the 6 to 10 inches thick mattress. If you choose thicker than the range limit, there will be a risk or falling overboard during sleep.

Size of mattress

Since discussing here on the mattresses for bunk beds, you need to be careful about the size. If you pick large or small than your need, you will fail to fit it on the bed perfectly.

I hope our discussion on different designs will help you choose the best one.


Bunk beds are usually we buy for our kids or tin’s use. So, generally, the mattress will be for the child, and you must get one that has a high level of durability. Else you may have to replace the bed just after a few days, and that will waste a lot of money.

Though there is a big chance of a nighttime accident, it will not be a bad idea to go for a waterproof mattress if your child is younger. The waterproof mattress added another layer of protection, which helps the bed lasting for a long time.

So, before buying your mattress, you must check user reviews and manufacturer offers to ensure the durability.


Do you know what the breathability of a mattress is? It means how much airflow will be allowed to reach the users at night. It's an essential consideration for selecting the bunk mattresses.

If the mattress fails to provide enough airflow, it will be quite difficult for the user to regulate their body temperature. As a result, they will spend a restless night.


The firmness is an essential feature of any mattress. It means the consistency that a bed can provide the sleeper. The more firm your mattress is, the less you will sink in it. The firmness of the bunk beds box springs depends on the performance of the child.

If your kid is 4 years or less, and you want to buy bunk bed mattress for his/her, then you should go for a firmer mattress. Because it will help you to ensure there aren’t any suffocation hazards.

On the other hand, if your mattress is for an older child, then the firmness level will depend on their demand for comfort. Just like adults, some kids like the feel of a firmer bed while others prefer softer mattresses.


There are plenty of certification boards and different institutions for certifying mattresses. All of these institutions and boards cover the manufacturing processes along with different types of mattresses.

As a customer, you have to make sure that the bed you have select for purchasing has a certification label on it. If there is not any label, it means the mattress has not tested thoroughly. Moreover, the quality of the product may also reduce.

So, before making the final decision, check all labels on the mattress carefully, and if there is any confusion, then don’t forget to ask the supplier.

Safety from Allergens

If your kid has an allergic problem with fiber or dust, you must be careful to choose the mattress. Many suppliers offer 100 days return policy for their beds.

You can pick one from there to watch that if your kids have any problem with it or not. Even if your child doesn’t have an allergy to anything, you must be careful with it. Because many mattresses can play a crucial role in making an allergic attack, and it can be dangerous, especially for kids.

Ask your kids

Do you ask your kid about his/her choice? Not yet? Every child is different from each other. So, it is quite essential to know that if they have their own choice or not before selecting. Be sure that whether they prefer a softer or a firm mattress before making your purchase.

Think about box spring

It's a bed base with a wooden frame and either metal rods or springs which provide excellent support to a mattress. Usually, it is the same size as the mattress, which sits on it.

Most of the bunk beds do not use box bed spring-like one level or regular beds. That means you have to find a mattress that durability built into it and has enough support so that it becomes unnecessary.

If you fail to find something highly durable, you may risk getting an expensive and high-quality mattress, which will fall apart quickly.

Some more characteristics of twin mattress for bunk beds

We have stated some consideration for buying the best bunk mattress on the above discussion. Hopefully, now it will be easy for you to select something best. But if you are still in confusion, then bellow listed characteristics will help you to pick the right one. 

1.    Weight

Weight is an essential characteristic of the mattress because most of the bunk beds have a limited weight capacity for each level. For example, a standard bunk bed might have a weight capacity of 200 lb for the top bunk and approximately 500 lb capacity of the bottom bunk.

So, it is essential to check the mattress's actual weight before making the final decision. Remember that the weight capacity refers to the bed and sleeper.

A full size, twin or twin XL mattress can weight from less than 50 pounds to more than 110 pounds. If a light option is your requirement, then a foam mattress can be the right choice. On the other hand, hybrid and latex is usually the most massive product.

 2.    Profile

Guard rail for bunk bed is a guard on the side of a foundation to prevent a sleeper from rolling out or falling off the bed. Almost all top level of bunk beds must feature with guard rails for preventing your kids from potentially hurting themselves.

So before making your selection, you should make sure that the bed remains protected by this guard rails.

3.    Temperature neutrality

It's another issue of these mattresses. Some allow cool, while some retain a large amount of body heat from them. That means a temperature neutral mattress helps to improve the duration of sleep.
Latex, hybrids, and innerspring beds usually come with it.

4.    Conforming and pressure relief

A right mattress should reduce pains and aches throughout the sleeper’s body. Because a low-quality mattress can add discomfort. Many cushions relax the pressure points and ease pain by comforting the user’s body.

It can form a strong impression around sleeper’s figure, which improves spinal alignment and releases tension, especially for side sleepers. The best supportive mattresses include latex models, memory foam, as well as a hybrid bed with thick comfort layers.

5.    Cost

Most of the mattresses that fitted for bunk beds come with a lower profile and smaller size. As a result, they are usually lower than the average price level. On the other hand, shoppers also look for a cheap twin mattress for bunk beds with the best quality.

However, if you ready to pay some extra for your mattress built, then there are some luxury materials like gel-infused foams, organic textiles, or natural latex.

Frequently asked questions

Are you become confused with the plenty of tips and buying guides that we listed about selecting the mattresses for bunk beds? As a buyer, various questions can knock in your mind.

To make it easy for you, here are some of the questions you can frequently ask regarding the best mattress and box spring.

Question : How tall are bunk beds?

To prevent bumps from the ceiling, you should keep a space minimum of two feet from the bunk bed. The Everage height of the bunk bed is between 5.5 feet to 6 feet.

Question : How much space should be between top and bottom bunk?

It's the space between the very bottom bunk with the top, and it should be 38 inches for adults though the average clearance is 33 inches.

Question : Is a bunk bed mattress different?

The answer is ‘no.’ There is no significant difference between an ordinary mattress and a bunk mattress. Even you can use a regular mattress on a bunk bed.

Most of the bunk bed mattresses are low in quality and thin also. That’s why it recommended that at first, you should try the supplied mattress, and then you can replace it if you think it is too thin or too soft.

Question : As the bunk mattresses are quite thin (I’ve received one about 3 inches only), are they ok for a kid of 3 or 5 years old? 

Sorry, I don’t think that only 3 inches thickness will be ok for kids of 3 or 5 old. So, it recommended that the bunk bed mattresses should be at least 4 inches in depth.

You may have seen that we have chosen at least 5 inches thick mattress for this review because a thick mattress is comfortable and safe for kids.

Question : Is a 10 inch mattress thick enough for kids?

Yes, it will be right for kids. But remember that it would be suitable for only a bunk bed with a 14-inch high guard rail.

Question : Are all bunk mattresses only in a twin size? Both of twin babies can sleep on a single mattress?

Twin mattresses mean two different beds are in the same size and design. The general measurements of these mattresses are 75-inch × 38 inches. As these mattresses are not wide enough, your babies will not be comfortable on a single bed.

Question : If I want to buy a twin bunk mattress, and then is two mattresses will come in a single pack, or I need to purchase two separate mattresses? 

As we already said that “twin” just a simple example. It does not mean that all bunk bed mattresses come in two different pieces. If you want to purchase a twin mattress, then the supplier will deliver two separate types, which will be the same in size and design.

Question : How to put sheets on a loft bed?
