These two mattresses are very confusing as they’ve got similar features but they still differ in many ways. Let’s look at both of their similarities and differences so that you can have an easy time deciding.

Amerisleep VS Casper Mattress Features Comparison

Before you make a decision on whether to buy Amerisleep AS3 or Casper mattress, you should find out how they are constructed. Both of them feature foam but they vary in height and thickness.

Amerisleep Construction

Amerisleep AS3 features Bio-Pur memory foam, affinity transition poly foam, and Bio-core support foam. These materials provide a healthy and cool sleeping environment.

To start with, it has a cover infused with celliant that is clinically proven to help people with pain recover quickly. The mattress also helps the user to fall asleep 15-minutes quicker than other all-foam mattresses on the market. Another vital layer is the 3-inch of Bio-Pur foam. This layer is made of memory foam and it conforms to your body while allowing you to cool down at the same time. The layer is also eco-friendly as it is made of plant-based materials.

Other layers include the 2-inch affinity layer and a 7-inch bio-core layer. The Affinity layer acts as the transitional layer between the other layers and it provides support and makes the mattress responsive. Last but not least, there is the 7-inch bio-core layer. This is the layer that supports other layers on top and makes the mattress durable. Additionally, it helps to keep your shoulders and helps in their natural position.

Casper Construction

The Casper mattress is 9.5-inches in thickness and comes with 3 comfort layers. The layers include top and bottom polyfoam layers with a middle memory foam layer.

The cover of the Casper mattress is made of polyester and spandex materials. It makes the mattress breathable and comfortable at the same time. The top and bottom layers offer close body-conforming and give the mattress its medium-firm feel. The base layer is made of high-density polyfoam and supports the top layers. It also gives the mattress its shape and makes it withstand the weight.

When compared to the Amerisleep mattress, the Casper original mattress is very light and easy to move or change on the bed.

Durability

Considering that both of these mattresses are made of all-foam, it is easier for a person to think that they have the same durability. No, this is not the case as some users prefer the Amerisleep over the Casper mattress.

Casper mattress may hold up well according to various users, but it is very early to come up with a conclusion concerning the durability of this mattress since it has been in the industry for less than 10-years. However, it should offer good use for more than 6 years.

On the other hand, Amerisleep has been in existence for more than 10-years and it is easier to determine their durability. Many users of Amerisleep say that the mattress doesn’t hold up very well and they degrade quicker. So, you should get at least 7 years of good use which is on ace with other quality memory foam mattresses.

Firmness

This is one of the features that the Amerisleep AS3 and Casper original share. Both of these mattresses have a medium-firm that is rated as 5.5 on the firmness scale of 1 to 10. This means that both of the mattresses can be utilized by different sleepers as they are neither firm nor very soft.

Also, both Amerisleep and Casper have other models that users can pick from to meet their sleeping demands. For instance, Amerisleep has 5 different models while Casper has 4 models to pick from.

Temperature neutrality

Finding a breathable all-foam mattress is not easy as most of them sleep hot. Amerisleep and Casper are some of the most breathable all-foam mattresses on the market. However, Amerisleep sleeps cooler than Casper as it features a cover that is blended with celliant. Many users say that Amerisleep is way cooler than many memory foam mattresses that they’ve used in the past.

All-in-all, these two mattresses are made to sleep cool as the Amerisleep comes with the celliant cover while Casper has a thin cover that is breathable and comfortable for easy circulation of air.

Motion isolation

This is a very important factor, more so for partners who are distracted in bed by their mates. A mattress with poor motion isolation can be a nightmare as a slight movement by your partner may end up waking you up.

With the Amerisleep AS3 and Casper original, you won’t face such challenges. This is because these mattresses are made of all-foam, which is good at absorbing movement. According to owners of these mattresses, they say that both of them provide great motion isolation making the bed suitable for partners.

Conforming

Besides absorbing significant motion, these two mattresses are also good at conforming to the user’s body. This is because they are both made of all-foam materials. The Amerisleep mattress features memory foam while Casper comprises memory foam and polyfoam materials. As a result, Amerisleep offers more conforming than Casper.

If you want a mattress that offers greater pressure relief, then Amerisleep will be the better mattress. This is due to the unique celliant cover that it has and the memory foam layers. Casper has polyfoam on top and high-density polyfoam at the base which is not very good at conforming when compared to memory foam.

Edge support

Even though Amerisleep is made up of memory foam, it has polyfoam in its edge support which makes it stronger than most all-foam mattresses. This is not the same case with the Casper mattress as it doesn’t come with any support in its edges. Therefore, it won’t be able to support your weight and it will tend to sink after a few years of use. For the Amerisleep AS3 mattress, users have recommended it and they say that it provides good edge support when compared to other foam mattresses.

Sex

One of the features that these mattresses lack is the bounciness and responsiveness of innerspring mattresses. This is a huge challenge if you want a good mattress for sex. At the same time, this doesn’t mean that this is not a good mattress for the bed.

Like many other all-foam mattresses, the Amerisleep AS3 and Casper original won’t give you a bouncy or responsive surface. So, if you’re a couple looking for a bed that is very responsive and easy to change position on, then you will have to look elsewhere.

Noise

This is one of the most exceptional features of these two mattresses. If you’re a person who doesn’t like disturbance while sleeping or even changing position on your bed, then you will love both the Amerisleep and Casper mattresses. This is because both of these mattresses are virtually silent when you sit or sleep on them. With no coils or springs in their structure, memory foam alone can’t produce noise.

Off-gassing

If you decide to purchase all-foam mattresses, this is something that you should be ready for. It is normal for memory foam mattresses to produce gas or odor when they are still new. But this is something that lasts for some days and it will be gone. Both the AS3 and Casper mattresses produce gas for a few days when they are unpackaged. Amerisleep users say that the gas lasts for only a few days before disappearing completely. Casper takes slightly more time but it also dissipates quickly.

Trial period

This is another feature that both the Amerisleep and Casper mattress share. Casper offers a 100-nights free trial period, and so does Amerisleep. Within this period, the buyer is free to try out the mattress and return it if they feel it is not offering the support and comfort that they were looking for.

However, the policy defers as Amerisleep requires the buyer to break-in for 30-nights before thinking of returning, while Casper doesn’t require buyers to break-in period for a full refund.

Returns and shipping

When it comes to returns, Amerisleep requires their clients to break-in for 30-nights before receiving a full refund in case they decide to return the mattress. Also, Amerisleep offers a full refund without charging their clients a single penny. This includes transportation and shipping.

On the other hand, Casper also offers a full refund to the client. This includes transportation and shipping. However, mattresses bought outside the Casper online store such as on Amazon ad other brick-and-mortar stores will incur some additional charges if they ask for a full refund.

Note that free shipping is offered for the US and not other areas.

Price

The Casper mattress is cheaper than the Amerisleep mattress. This does not only apply to the flagships mattresses alone but as well as the other mattresses, too. As a matter of fact, Casper original is cheaper than the cheapest Amerisleep mattress.

Warranty

Casper offers its clients with a 10-year warranty while Amerisleep offers a 20-year warranty. Casper’s warranty is totally non-prorated but it can become void if a sturdy foundation is not applied. For Amerisleep, it has a partially non-prorated warranty that lasts for the first 10 years and a prorated warranty that lasts from year 11 to 20.
