If you’re a big admirer of Casper’s “bed in a box” concept, you might be wondering how long the mattress can remain sealed in the packaging before being unpacked and used.

Casper’s bed-in-a-box is often regarded as the best available. Casper mattresses cannot be stored properly in a package for less than three months.

Choosing the right mattress is an important purchase.

After all, we spend around one-third of our lives in bed.

Therefore, a mattress must be durable, comfy, and supportive.

When faced with a plethora of options, it’s normal to feel anxious about making the right decision.

There is nothing to worry about in terms of quality, materials, promotions, or shipping alternatives.

If you want to buy a bed in a box but don’t know where to start, read this.

Keep reading to find out more about the Casper mattress and what sets a mattress in a box apart from a regular bed.

What Is A Mattress In A Box?

Beds in a box are regular beds that have been compressed using industrial technology and placed in an airtight bag.

This approach is more compact, flexible, and portable than a standard mattress.

It is true that buying online saves money and provides more options for the buyer.

What to Know About the Casper Mattress

Casper’s three foam layers work together to reduce motion transfer, adapt to your shape, and provide targeted support for your lower back and other trouble spots. You may also buy this mattress online and have it shipped to your door. You can get a real sense for how well you sleep on the Casper mattress by giving it a try for 100 nights after it is delivered to your door.

Although there are many advantages to the Casper mattress, it is important to remember that no mattress is designed to meet the needs of every possible sleeper. Let’s go over the ins and outs of this mattress, including who it’s ideal for and who it isn’t, the materials it’s built from, and more.

What to like about the Casper

  • This memory foam mattress sleeps surprisingly cool for the type thanks to its permeable foam layer.
  • The Casper is inexpensive, with a queen size going for less than $1,500.
  • The zoned support system is especially beneficial for side sleepers.

What to not like about the Casper

  • That bed was not made for somebody weighing more than 250 pounds.
  • The lack of contouring means that people who want the cuddling sensation of memory foam will be disappointed.

Who the Casper is Best for

Side sleepers

Due to its zoned support foam, which aids in maintaining spinal alignment, the Casper is a great option for side sleepers. The Casper has three layers and is a medium-firm mattress. Pressure points, such as the hips and shoulders, are supported by the bed’s firmest sections, while the feet and shoulders are cushioned by the bed’s plusher sections.

Hot sleepers

Pure memory foam mattresses have the tendency to soak up your body heat during the night, leaving you uncomfortable and sticky when you wake up. However, the Casper team has some tricks in their sleeves, including a polyfoam cover that is perforated to promote ventilation and heat dissipation.

Who the Casper is not best for

Stomach sleepers

Sleeping on one’s stomach causes the body to slump forward, putting extra strain on the lower back and the neck. While the Casper’s zoned support foam does help alleviate pressure in these specific places, our reviewers did not find it to be a good option for stomach sleepers due to its overall softer feel. Our guinea pigs agree that if you care about your hip alignment, you should look into hybrid options.

Larger-sized sleepers

The Casper mattress is well-suited for most sleepers, however it may not be ideal for those who are particularly heavy or tall. They need the extra stability that a hybrid or innerspring mattress provides, which memory foam does not provide. Larger members of our testing team experienced hip and shoulder sinkage on the Casper mattress, which could have been alleviated by the use of coils.

How the Casper Mattress Sleeps

Casper’s superior pressure relief, reactivity, and motion isolation make it a top pick. The Casper lacks the contouring of many memory foam mattresses, so it won’t give you the snug feeling that’s expected from these beds. This mattress has a nice blend of firm and soft qualities, so it could be a good fit for those who are looking for a bed with a medium level of firmness.

Pressure relief

Pressure points, such as the hips, lower back, shoulders, and neck, are particularly vulnerable to damage from sleeping on the improper mattress. A good mattress won’t make your aches and pains worse and may even help relieve pressure points, allowing you to have a more restful night’s sleep. The Casper’s weight is distributed evenly throughout the mattress thanks to its zoned foam support system.


Compressed foam can hinder air circulation and trap body heat, leading to a common complaint about memory foam mattresses. While the Casper is a cooler alternative than many memory foam mattresses, sleepers who tend to become quite warm would do better on a more breathable option like a hybrid or innerspring mattress.

Motion isolation

If you or your partner are restless sleepers or if you share a bed with a light sleeper, motion isolation should be a top priority for you. To avoid awakening your mate when you get up or move around in the night, you can get a mattress that reduces the effects of motion. Our sleep experts found that the Casper provided great motion isolation and made it possible to get up and move about without waking up a sleeping spouse.


Any time you move around on your mattress, you shouldn’t feel like you have to struggle against it. A responsive mattress does just that. The responsiveness of innerspring and hybrid mattresses is well-known, as they do not restrict movement during sleep. The Casper is unlike other memory foam mattresses because it maintains its responsiveness while maintaining its contouring capabilities. Our team of reviewers gave this bed a perfect grade because of how well it responded to their every movement while sleeping.


Since purchasing a new mattress represents a substantial financial commitment, it is important to find one with a long lifespan. As a result of its high-density foam foundation, the Casper is a mattress that can survive the test of time. Our durability tests gave it an 8 out of 10 overall score because of this.

Edge support

When sleeping on a mattress, have you ever come dangerously close to falling off the side? When you lie or sit on the edge of a mattress and it collapses in on you, it lacks edge support in its construction. You’ll be able to make full use of the sleeping surface (and even feel supported just sitting on the edge) with the Casper, as its side support is just as good as that in the mattress’s middle.

Key Features of the Casper Mattress

Materials and construction

The Casper mattress is an all-foam structure with three distinct layers: a top layer of breathable foam, a layer of zoned support, and a base layer of support foam.

Top layer

Casper’s plush top layer is comprised of perforated polyfoam to improve airflow and relieve pressure. This foam strikes a nice mix between softness and bounce, so you may relax without becoming trapped.

Middle layer

Casper’s zoned support layer, located in the mattress’s midsection, is intended to provide more assistance where it’s required most (the hips and lower back) while also cushioning the sleeper’s shoulders and feet.

Base layer

Casper uses a high-density foam in its mattress foundation, which guarantees consistent comfort and durability.

Returns and warranty

Casper stands behind the quality and longevity of their mattresses with a 10-year warranty that covers any flaws in construction or materials. There is a 100 percent money-back guarantee for mattresses that are returned due to defects. Even better, Casper will pick up your old mattress at no extra cost to you. It’s important to note that using an unsuitable bed frame may render your mattress warranty null and void. Casper provides insight into making the best decision.

Trial period

Although guarantees from the manufacturer are helpful in the event of a faulty product, what if you simply don’t take to the bed the way you had hoped? That’s why the risk-free sleep trial exists. The 100-night sleep trial that comes standard with every Casper mattress gives you plenty of time to try out the bed and see whether it works for you. The mattress can be returned for a full refund if you decide you don’t like it. During the trial period, Casper will pay for the cost of shipping back to them.

Delivery and shipping

Given that Casper is a “bed-in-a-box” brand, transporting and delivering the product is a breeze. The mattress may be purchased from Casper or Amazon online and then shipped to your doorstep compressed and wrapped up into a box for easier transport. The Casper mattress is ready for use as soon as it is unboxed and given a few hours to grow to its full size.

What Is The Casper Mattress Firmness?

It’s neither too soft nor too firm; the Casper mattress strikes a happy medium. But Casper has a number of different versions, each of which might provide the sleeper a slightly different experience. Learn more about the firmness of a Casper mattress by taking a look at their best-selling Casper Original and other variants.

Is Casper Original firm?

On a scale from 1-10, the Casper Original scores a 5. The Casper Original Hybrid has a coil support layer instead of polyfoam, although both versions employ three foam layers. The Casper Original Hybrid has a similar medium feel, but the coils give it a bit of bounce.

The Casper Original is unique in that it is a zoned foam mattress. This ensures that your entire body is supported while your spine remains in a neutral position. The bed’s foam is also zoned, with softer sections at the shoulders and harder sections at the hips, waist, and lower back.

Are Casper mattresses firm or soft?

The firmness level of Casper mattresses is somewhere in the middle, between the extremes of soft and hard. Users rate the firmness of the Casper Wave Hybrid at 6.5 out of 10, with some of the milder areas including the shoulders and upper back. In this model, Casper begins with a layer of polyurethane foam treated with a cooling agent, then layers of natural latex, memory foam separated into zones, polyurethane foam studded with gel pods, and lastly a base of polyurethane foam atop enclosed coils.

Similar to the Casper Hybrid, the Casper Nova Hybrid is rated as a medium-firm mattress by sleepers. However, the Nova Hybrid is Casper’s plushest offering, boasting a velvety soft layer, pillow-like fabric, and 7 ergonomically placed support areas. In conclusion, the two layers of polyurethane foam in the Casper Element mattress contribute to a medium-firm feel, earning it an average score of 6 out of 10 from sleep testers.
