Full Mattress Review

Casper and Amerisleep are established brands that have built strong businesses around selling mattresses online. In fact, they’ve both even built up enough of a following to open some of their own branded brick-and-mortar mattress showrooms. It’s no surprise, then, that many people looking for a new mattress wind up choosing between them.

Both Casper and Amerisleep have a diverse product line with multiple mattress models, allowing customers to select the bed that best suits their budget, firmness preference, and support needs. Having a handful of options, though, can make it hard for some shoppers to know how to choose between Casper and Amerisleep.

Our in-depth comparison introduces all of their offerings including the Casper Original, Casper Hybrid, Casper Wave Hybrid, Casper Nova Hybrid, and the affordable Casper Element as well as the AS1 through AS5 beds from Amerisleep. We put these products head-to-head, evaluating their price points, performance characteristics, and standout features while also covering what you need to know about shipping, warranties, and returns.

Sizing and Weight Options

There are some straightforward, nuts-and-bolts factors that can influence your mattress shopping. Among those are the size, weight, and height of a mattress.

Getting the right mattress sizes helps ensure that there’s enough space for you and, if necessary, a bed partner, to stretch out and feel comfortable. However, the mattress also has to fit in your bedroom without making the space feel crowded.

Choosing the right height is important for making sure that your fitted sheet will actually fit, and height can also affect how easy it is to get in and out of bed.

The weight of a mattress matters the most when you have to move it. Most mattresses require two or three people to move them safely, but even with helping hands, a really heavy bed can be a chore to relocate. For those who move with regularity, a lighter mattress may be a priority.

In terms of their dimensions, the offerings from Amerisleep and Casper have a great deal in common. The height is comparable among their offerings, and normal fitted sheets should fit all of the models. Both companies make all of their mattresses available in all of the six standard sizes. The primary differences include:

• Amerisleep specifically offers a Split King option, although Casper customers can purchase two Twin XL mattresses to serve the same function.
• Casper offers both hybrid and all-foam mattresses while Amerisleep only has all-foam options.
• The hybrid mattresses from Casper weigh significantly more than the foam options from either company. It is normal for a hybrid to be heavier because the innerspring component weighs more than foam.

Construction and Materials Comparison

Knowing about the construction of a mattress provides meaningful insight about what to expect from that mattress in terms of performance and durability.

Some quick terminology can provide useful background about the interior construction of mattresses. The comfort system, which can involve more than one layer, is toward the top of the mattress and most directly influences the bed’s feel. The support core is toward the bottom and acts as the ase for the mattress.

A hybrid mattress has a support core made with coils plus a thick comfort system above it that can incorporate a number of types of materials. An all-foam mattress uses a polyfoam support core and also has a comfort system that can utilize different types of materials.

Both Casper and Amerisleep mattresses demonstrate thoughtful design, a fact that becomes clear in reviewing the construction of each of their product offerings.

Casper

Casper has five total mattress offerings. Two of these are all-foam, and three are hybrids. All of these mattresses have the same cover, which is made of a blend of polyester derived from recycled plastics, regular polyester, upcycled cotton, rayon, and spandex. This combination of materials makes the cover stretchy, breathable, and eco-friendly for its role in helping to keep plastic bottles out of landfills.

Casper Original & Casper Hybrid 

As the name indicates, the Casper Original was the first mattress launched by the company. It has an all-foam design and three  interior layers:

• 1.5 inches of specialty polyfoam
• 2 inches of 3-zoned memory foam
• 7 inches of base polyfoam

The Casper Hybrid is an adaptation built upon the success of the Casper Original. In this mattress, the top three layers — the comfort system — are the same, but the support core is different. In total the Casper Hybrid has three layers:

• 1.5 inches of specialty polyfoam
• 2 inches of 3-zoned memory foam
• 7 inches of pocketed coils with a perimeter foam encasement

In both of these mattresses, the mixture of two distinct foams in the comfort system creates a blend of both contouring and bounce. In the Casper Hybrid, that bounce is amplified by the innerspring coils, and its edge support also gets a boost from the coils and the encasement of high-density foam that goes around them. Both the Casper Original and Casper Hybrid have a medium (5) feel.

Casper Nova Hybrid

The Casper Nova Hybrid is one of the newest mattresses launched by Casper, and it has four interior layers:

• 1 inch of AirScape polyfoam
• 1.5 inches of 3-zoned AirScape polyfoam
• 2 inches of 7-zoned memory foam
• 7 inches of pocketed coils with a perimeter foam encasement

The Casper Nova Hybrid has a more plush feel — medium (5) — while maintaining spinal support through its mix of foams. The AirScape polyfoam in this model is built to be breathable and soft yet still responsive. The zoned foams work to reinforce the mattress under heavier parts of the body, and memory foam adds to the contouring and pressure relief of the Nova Hybrid.

Casper Wave Hybrid

The Casper Wave Hybrid is a luxury model that incorporates a number of design innovations from Casper’s product development program. It has five layers:

• 1 inch of AirScape polyfoam
• 1.5 inches of AirScape polyfoam
• 1.5 inches of 3-zoned AirScape foam
• 1.5 inches of zoned polyfoam with targeted gel pods
• 7 inches of pocketed coils with a perimeter foam encasement

The Wave Hybrid takes advantage of Casper’s specialty AirScape polyfoam, which is put to use in the top three layers. In the third layer, a zoned AirScape formulation is used to provide greater comfort and support to the midsection. In addition, the polyfoam with targeted gel pods allows the mattress to provide a feel that is more tailored to each sleeper’s weight distribution. The thick coil layer with a perimeter encasement generates stability, bounce, and edge support. The overall comfort feel of the Wave Hybrid is medium (5).

Casper Element

The Casper Element is the company’s affordable all-foam option. It also has the firmest feel — rating as medium firm (6) — among Casper’s product lineup. It has a no-frills interior design with just two layers:

• 3 inches of AirScape polyfoam
• 6.5 inches of base polyfoam

Though it lacks the advanced features found in other Casper models, the Element provides a solid, entry-level mattress that can cushion the body’s pressure points without allowing too much sink.

Amerisleep

Amerisleep sells five mattresses, and all of them are all-foam beds with similar materials. The primary difference between these options is the thickness of the interior layers and the firmness feel.

Some components are found in all of the Amerisleep mattresses and include:

• Cotton-blend cover: Amerisleep mattress covers are made from a breathable blend of cotton and polyester, which help the surface sleep relatively cool.
• Bio-foams: Many of the foams used by Amerisleep are created by substituting plant-based oils for some of the petrochemicals normally used in foam production. As a result, the Bio-Pur memory foam and Bio-Core base polyfoam have a lower carbon footprint than foams found in many other mattresses. The Bio-Pur foam has a density of 4 pounds per cubic foot (PCF), which is above-average for memory foam and contributes to its durability.
• Surface Modification Technology (SMT): This design of polyfoam, called HIVE by the company, creates five zones across the foam to better support different regions of the body.

The AS1 is the firmest of the Amerisleep mattresses and has the thinnest total comfort system. It has a firm (7) feel and two interior layers:

• 2 inches of Bio-Pur memory foam
• 8 inches of Bio-Core base polyfoam

The AS2 has a medium Firm (6) feel and three total layers:

• 2 inches of Bio-Pur memory foam
• 3 inches of 5-zoned SMT polyfoam
• 7 inches of Bio-Core base polyfoam

With the addition of the SMT polyfoam, the AS2 offers greater tailoring to the body relative to the AS1.

The AS3 has a medium (5) feel and three interior components:

• 3 inches of Bio-Pur memory foam
• 2 inches of 5-zoned SMT polyfoam
• 7 inches of Bio-Core base polyfoam

In the AS3, the SMT foam layer is thinner than the memory foam layer, creating a slightly softer and more contouring feel.

The AS4 has a medium soft (4) firmness level and three layers:

• 4 inches of Bio-Pur memory foam
• 1 inch of 5-zoned SMT polyfoam
• 7 inches of Bio-Core base polyfoam

The AS4 has the thickest memory foam layer of all the Amerisleep mattresses, making it a standout performer when it comes to motion isolation and deep contouring.

The AS5 has a soft (3) feel but with four layers:

• 3 inches of Bio-Pur memory foam
• 2 inches of ActiveFlex polyfoam
• 2 inches of 5-zoned SMT polyfoam
• 7 inches of Bio-Core base polyfoam

The AS5 adds a layer of ActiveFlex polyfoam that has a latex-like feel. This makes the AS5 more responsive than the other Amerisleep models even though it still has a plush comfort level.

In all of the Amerisleep mattresses, the Bio-Pur memory foam in the top layer provides notable pressure relief and motion isolation. In addition, the base polyfoam generates a sturdy feel and bolsters the performance of the comfort system.

In-Depth Ratings

Delineating between mattresses isn’t always easy, especially since there’s frequently quite a bit of technical jargon and marketing buzz. However, as you drill down into the details about mattress construction and reviews, you can better understand the strengths and weaknesses of any mattress. Considering these key features and performance characteristics can help you most effectively identify a mattress that’s going to suit your needs.

• Durability: Almost all mattress shoppers want a bed that’s built to last. Shoddy materials or construction can mean premature sagging and faltering back support. To get the best performance and return on investment, look for mattresses with thoughtful design, quality materials, and clear attention-to-detail in overall construction. For people who put more potential strain on their bed, such as people over 230 pounds and those with sharp pressure points, look for a thicker comfort system because that can contribute to the longevity of the mattress.
• Motion Isolation: For people who share a bed, it’s important that one person’s movement — whether from tossing and turning or getting up from bed — doesn’t cause the other person to wake up. A mattress with good motion isolation serves this goal because its materials keep vibrations across the bed to a minimum. Of all mattress materials, memory foam has the strongest reputation for isolating motion.
• Sex: Sleeping gets most of the attention when choosing a mattress, but that doesn’t mean it’s the only activity to consider. People with an active sex life want to make sure that their new mattress doesn’t get in the way of their intimate activity. A mattress can interfere with sex if it allows too much sink and is slow to rebound when weight is adjusted on its surface. Bouncier materials, including coils, latex, and latex-like foams, tend to better facilitate sex.
• Temperature Neutrality: If a mattress builds up heat or causes heat to collect around the body, it can lead a sleeper to wake up sweating in the night. This happens most often when the comfort system has deep hug that cuts off airflow around the skin. In addition, some materials naturally retain more heat than others. Various design elements included in the cover, comfort system, and support core can all be used to try to improve temperature neutrality.
• Pressure Relief: Pain-free sleep means making sure that the body gets the support it needs, and of course, some parts of the body need more cushioning than others. A mattress that can accommodate those pressure points not only minimizes soreness in those areas but also contributes to healthy spinal alignment. Various types of materials can relieve pressure, especially foams, including memory foam, with at least moderate contouring.
• Off-gassing: Almost every mattress will have a “new mattress smell” when it is fresh out of the box. The smell comes from volatile organic compounds (VOCs) that are created during manufacturing but get held inside the bed’s packaging. These VOCs aren’t a health risk and usually dissipate within a few days, but the smell can be bothersome, especially for those who have allergies or are very smell-sensitive. In most cases, foams give off the most odors, so mattresses with more and thicker foam layers have more off-gassing issues.
• Ease of Movement: With some mattresses, it’s possible to feel stuck in place or like you’re in a pit of quicksand. While certain sleepers may prefer this feeling, it can restrict ease of movement, including when you want to get out of bed, switch up your sleeping position, or engage in sexual activity. Mattresses with more bounce and less pronounced sink usually permit smoother movement.
• Edge Support: Making the most of your whole mattress surface requires edge-to-edge stability. If a mattress has poor edge support, it may feel like you’re going to be ejected from the bed when sleeping near the perimeter. The mattress may also feel unstable when sitting on the edge. All-foam beds tend to have the weakest edge support because of the way the foam compresses while hybrids typically are sturdier around the perimeter.

No mattress is perfect in all of these categories. For example, excelling one area, such as deep contouring and pressure relief, can make a mattress more prone to issues with temperature neutrality or ease of movement. For that reason, every shopper can consider their own priorities and the mattress that best meets them. To help in that process, our breakdown of the ratings for each of the Casper and Amerisleep models are described below.

In-Depth Pricing

A mattress is a significant investment, and it’s normal for a quality mattress to cost more than a poorly made one. That said, even a quick foray into mattress options reveals that there’s a huge range of prices. Some of the biggest factors that influence mattress pricing include:

• The type of materials used
• The thickness of the layers/materials
• The total number of layers
• Special features (including those for cooling, cleaning, or bodily recovery)
• Specialty materials (including organic or eco-friendly materials)
• Where the mattress was manufactured

Both the Casper and Amerisleep brands include mattresses with a spectrum of price points so that there are compelling options for people of almost any budget. The prices for each model, listed by size, are outlined below. Keep in mind that these are retail (MSRP) prices, and that promotions and discounts are almost always available to reduce your final cost.

Casper offers more options for budget shoppers than Amerisleep since both the Casper Element and Casper Original are offered at a lower price than the lowest-cost AS1 from Amerisleep. The Element, in particular, is the most accessible product to people operating on a tight budget.

The most expensive option from the two companies is the Casper Wave Hybrid, which has a higher price tag than Amerisleep’s AS5. Casper’s Nova Hybrid is also nearly as costly as the AS5 as well.

Overall, both companies have quality mattress options within a wide price range, and both frequently offer coupons or discounts that can help savvy shoppers get an even better value by taking advantage of a mattress sale.

Trials, Warranty, and Delivery

Casper and Amerisleep have strong reputations for their customer service, and part of that derives from how they handle shipping, returns, and warranty issues. For people who are buying a mattress online for the first time, knowing about these topics can assure that you have the best mattress buying experience.

Shipping

The standard way that online beds are delivered is as a mattress-in-a-box. Using this method, the mattress is compressed snugly into plastic packaging, carefully put in a cardboard box, and sent to your front door via ground shipping services. There’s no assembly required; you just need to carry the box inside to your bedroom and remove the packaging so that the mattress can retake its full size. It is advisable to have two people working together to safely lift and set up the mattress.

Special mattress delivery services may be offered that include a team of technicians who come to your home and set the bed up for you. In most cases, this White-Glove delivery service also involves removal of an old mattress.

Casper Shipping Policies

Casper provides free standard shipping in the contiguous 48 U.S. states and Canada. Shipping to other addresses, including Alaska, Hawaii, and some international locations, is available at an extra cost. In the contiguous U.S., orders usually arrive within 5 business days, and expedited delivery may be offered in some areas.

Casper offers an In-Home Delivery and Setup service that costs $149 and includes installation of the Casper model of your choice and haul-away of an old mattress.

Amerisleep Shipping Policies

Amerisleep offers free standard shipping using FedEx for orders in the contiguous United States. These deliveries usually arrive within 5-7 business days. Delivery is offered to Alaska, Hawaii, and some other countries for an extra charge. Shoppers in those locations should contact Amerisleep directly for a price quote on shipping.

White-Glove delivery is only offered by Amerisleep for customers who purchase a bed base.

Sleep Trial and Returns

To give their customers a chance to try out a mattress, online mattress companies provide a sleep trial. During the trial, customers can use the mattress, and if they aren’t happy with it, return it and get a refund. Because a new mattress can take getting used to, some companies have a required break-in period before a return can be requested. Often, the mattress company will arrange for free pickup of a mattress to be returned, but in some cases, they may require the customer to coordinate local donation or in rare cases to pay for return delivery.

Casper Sleep Trial and Return Policy

The Casper mattresses come with a 100-night sleep trial that has no required break-in period. At any point within 100 nights after delivery, customers can request a return, and Casper will coordinate pickup of the mattress. Casper offers a full refund once the mattress is returned; however, charges for In-Home Delivery and Setup are not refundable.

Amerisleep Sleep Trial and Return Policy

Amerisleep provides a 100-night trial for all of its mattresses. There is a 30-night try-out requirement before a return can be requested. If you decide to return an Amerisleep mattress, the company will pick up the mattress at no cost to you and provide a full refund.

Warranty

A warranty provides coverage in case there is a major and unexpected flaw that arises in your mattress. Customers should know that defects are different from basic wear-and-tear, which isn’t covered by a warranty. The warranty also will not cover accidental damage to the mattress. Every warranty has a term (how long it lasts) and a remedy (what the company does if a defect occurs).

Casper Mattress Warranty

The Casper mattresses are covered by a 10-year warranty. If a defect occurs, Casper will repair or replace the mattress with no charge to you, including for any warranty-related shipping.

Amerisleep Mattress Warranty

Amerisleep provides a 20-year warranty that provides coverage for defects in materials and manufacturing. During the first 10 years, Amerisleep will repair or replace a defective mattress at no charge. During years 11 through 20, a defective mattress will be replaced, but the customer has to pay 50% of the original price plus shipping charges.
