This is a splendid choice for anyone looking for a mattress in a box that is a fusion of memory foam and spring. The mattress provides excellent body contouring in addition to an exceptional level of firmness.

Let us analyse this one layer by layer. The first top cover is quilted very well, and it is also washable. It is made of antibacterial and antimicrobial materials.

The foam layer is made of a special material called float foam layer that gives an active cooling effect. I personally felt this mattress was exceptionally comfortable in terms of temperature regulation. It is also very soft and is soothing on pressure points across the back and limbs.

The next memory foam layer is light and soft that helps in keeping the pressure off the body during sleep. These foam layers are infused with graphite which helps in regulating body temperature as you move. 

The support layer is made with components that keep the mattress sturdy and strong for a long time. This layer also adds to the temperature regulating capacity of the mattress. Also, the filler foam on this one keeps your spine aligned throughout the night.

The foam casing is made of two layers to the highly effective spring system. It prevents the sensation of ‘rolling off the bed’ at the edges.

The springs are the best part of this mattress. It comes in pocket size that is a full 12 cm. It has over 1,500 springs that provide you with excellent support. 

The springs adjust to every movement of your body all night. Additionally, the size of the spring adds to the breathability of the mattress.

The base is made of superior quality materials that are anti-slip. So, everything on the bed stays in place, and you stay comfortable all night long.

This mattress consists of 2,500 springs in a king-sized model. Each of them is composed of 100% British steel. All the springs are made employing miQro pocket spring design. 

These cone-shaped models are patented. They are excellent in providing responsiveness, and they also weigh very little compared to other springs.

The cover of this mattress is made of hypoallergenic materials that can be good for anyone with sensitive skin. The cover is also highly breathable and helps in providing cool air circulation for the mattress.

The Elite Mattress by Brooke + Wilde can be an excellent choice if you want a restful night’s sleep. It is one of the most popular and also it is very easy to handle. These qualities put this mattress on the list of best mattresses in a box.

The mattress is made of ‘layer after layer of comfort’ to provide you with an undisturbed good night’s sleep. The mattress has received an award from the Good Housekeeping Institute.

It has eight layers that bring unique features to the mattress. Let’s get to the analysis of the layers.

The first layer is made of a removable and washable top cover. It can be unzipped easily to remove it from the mattress. The four-way stretch cover is made of breathable materials that can allow for an excellent level of air circulation.

The second layer is a memory foam protector layer. This is placed to allow the top cover to move independently of the foam and thus working to its full capacity. That will help in reducing the friction between the foam layer and the fabric.

The layers have an open cell structure that increases breathability and enhances the level of moisture evaporation. It will ensure to provide you with an environment that is cool and comfortable.

It has 2,500 mini spring pockets designed to move beneath as you turn around in your sleep all night. These springs add to the firmness of the mattress and give the necessary push back that is absent in foam only mattresses.

It has an additional layer of 1,000 springs. These springs are larger and are designed to provide a little more push and bounce.

It is easy to care for as well. You only have to rotate the mattress occasionally. It does not require flipping.

It provides relief against various types of fungal infection, including moulds. It is also effective against dust mites. These fibres are endorsed by Allergy UK.

I highly recommend this to anyone with sensitive skin and usually prone to allergies caused by materials in a mattress. The hypoallergenic materials in the fabric can be beneficial to them while providing much-needed breathability. 

The firmness of this mattress is excellent since it is not too firm or not too soft. That can be helpful if you are a combo sleeper or a side sleeper like me.

Buying Guide

Features to look for in Mattresses.


One of the prime checkboxes that your mattress must tick is the flexibility one. You are likely to adjust your bed to multiple positions, and your mattress needs to move with ease. Plus, this will also reflect the longevity of your mattress.

Comfort Level

What kind of a sleeper are you? Identify your sleeping habits and health conditions, if any, and choose the mattress accordingly. This piece of bedding has a prime role in ensuring your comfort, and that is what you need to check. Look for features like pressure relief, motion transfer, contouring, etc.

Type of Mattress

Another essential aspect that directly determines whether a mattress is for you or not is its type. While a latex mattress excels at providing a bouncy feel, the hybrid ones ensure pressure relief — ideal for back discomfort. The other two options include innerspring, which is relatively budget-friendly and foam — exhibiting the highest flexibility rate.

Air Circulation

Whether you are a hot sleeper or not, air circulation and temperature regulation are necessary features for your mattress. They allow you to sleep in a healthy environment while also preserving the mattress condition.


TIt is one of the basic points that you must double-check. You do not want to order a mattress that does not fit your bed base, do you? Therefore, thoroughly skim through the mattress measurements and compare them with that of the bed.

Split vs. Solid

If you have a split bed base, purchasing a mattress compatible with this design is the unspoken wiser decision. It will allow you and your partner to change position and firmness level independently.

Frequently Asked Questions

Mattress in a box or simply bed in a box is simply a mattress that is delivered to you in a box. The mattress is compressed to fit in a box using heavy machinery.

It is done to make it more practical and economical to store and transport a mattress. Once you remove the mattress from the box and the package, the mattress decompresses and becomes like any other usual mattress.

There are numerous reasons for putting a mattress in a box. Primarily, the mattress manufacturers do not have large spaces to store or money to spare for overhead costs. Secondly, it can make the delivery process much simpler and cost-effective.

Also, the processing of compressing the mattress in a cardboard box is easier to handle for buyers like you and me.

Once the mattress is at your doorstep, you can easily carry it inside and remove it from the packaging. The mattress will decompress itself to become like the regular mattress you see in the stores. 

It can take less than an hour, or it can take a few days for the mattress to decompress before it is ready to be used. The time will depend on the individual mattress design and its specifications.

Well, there are some cases of off-gassing and extra-base requirements concerning mattress in a box. However, as they say, exceptions are not examples. So, is a mattress in a box any good?

The answer to this question is a big yes. Let me explain. Firstly, they are available in a wide range of options. When the mattress in a box became a thing, I honestly did not believe they could be manufactured in these many varieties.

Well, the manufacturers proved me wrong. There is enough option that can suit all the different needs and preferences. The number of options can become overwhelming.

Mattress in a box is available in options that include a variety of memory foam types. While some come with gel, and some are without gel. 

It may appear to have limited options, but just take a look at all the mattress types listed above. You actually have so many options to choose from.

They also cover all the features provided by a traditional mattress. This includes spinal alignment, motion isolation, temperature regulation, and body contouring.

Many of these even provide features that are not present in a traditional mattress. That includes long trial periods and an easy return policy.

A lot of buyers are sceptical about purchasing a mattress in a box. It is understandable owing to all the misconceptions about these mattresses.

One of the common rumours about a bed in a box mattress is that it does not last long compared to traditional mattresses. That can not be far from the truth since they do last the same if not longer.

However, the lifespan of a mattress in a box is highly dependent on the brand you are purchasing from. It is very similar to a traditional mattress; hence all you need to worry about is how reputable the mattress brand is.

Secondly, it is highly dependent on the price you pay for it. The higher the price you pay, the better the quality of the mattress. 

So, if the compositions that go into making the mattress are durable, the mattress will also be durable. Hence, check for the quality of materials and the quality of the make.

In some cases, a high-quality box mattress can last more than 10 years. Generally, it all depends on the manufacturer and the materials, not really on the type of mattress when it comes to durability.

Buying a mattress in a box is a very convenient and fast-paced choice. However, unlike traditional mattresses, you can not immediately sleep on them.

When the mattress arrives in the box, it may seem like a big boxed present for you. So, you can immediately open and unwrap it. However, it is advisable not to use it right away.

Usually, the mattress may take anywhere from three days to a week to fully expand. Nevertheless, many new mattresses can be used way before that time.

That is done by employing new and more sophisticated technology in the making of mattresses. It is done to avoid the long waiting time for the user’s benefit.

These new mattresses are designed to expand to the full size sooner. It could mean that you could sleep on it the day it arrives home.

Nonetheless, it is always best to go through the specification and the user manual. That will help you to know the exact details about the expansion of your mattress. 

Also, if you do not want to take any risk and end up spoiling the mattress for good, you can always reach out. You can call customer service representatives or reach out via any other mode.

There are numerous considerations that you should keep in mind before buying a mattress in a box. These considerations go beyond easy shipping and convenient moving around of the mattress.

It ranges from how the mattress can regulate body temperature to the level of spinal alignment it provides. After all, you go to bed every day even if you don’t get the recommended amount of sleep (well, that’s me).

So, it must be nothing less than perfect. Now, go ahead and buy the best mattress in a box that suits your needs perfectly and nothing less.
