Amerisleep as3 mattress
The Amerisleep AS3 mattress is 12 inches tall and contains 3 inches of Bio-Pur®, 2 inches of Affinity with HIVE® technology, and 7 inches of Bio-Core®. Amerisleep also features a soft, breathable cover designed to promote airflow so you always sleep cool and comfortable.

Bio-Pur® is a plant-based memory foam, where manufacturers partially replace petroleum with castor oil. The result is a breathable, more responsive memory foam—potential sleepers won’t have to worry about feeling “stuck” or overheating at night.

The Affinity uses HIVE® technology, where hundreds of hexagonal-shaped segments form a 5-zone support system. Softer support rests under the shoulders and hips with a firmer feel in the head, back, and legs. HIVE® evenly relieves pressure points in the body and encourages spinal alignment.

Bio-Core® is a durable base layer found in every Amerisleep mattress. This base layer supports the body without risk of sagging for a long-lasting mattress.

The Amerisleep AS3 mattress has a medium feel, the perfect choice for side and combination sleepers. Plush and supportive foams contour to the body, relieving pressure points especially in heavier sections of the body, like the shoulders and hips.

Online vs. In-Store

Online mattress companies provide customers with high-quality mattresses at a lower price tag, plus extended sleep trials and easy returns. A major drawback to online shopping is the lack of opportunity to try out the mattress before buying. Also, since online mattresses include many bed-in-a-box brands, companies are less likely to offer a white glove delivery service.

Mattresses from brick and mortar stores allow potential shoppers to try the mattress before buying, with knowledgeable salesmen on hand to answer any questions. Most in-store companies offer same day or next day delivery. The downsides to in-store mattress shopping include pressure to buy from salesmen, short sleep trials, and potentially paying more.

What to Consider in an Online Mattress

Before buying a new mattress, take a look at mattress type, quality, and available sleep trials, return policies, and warranties. Keep in mind that the right firmness is based on your body type and sleeping position.

Mattress Type

Each type of mattress offers potential shoppers their own unique feel. Some sleepers prefer the bounce of an innerspring, while others enjoy the conforming feel of memory foam.

Memory Foam

When heat and pressure are applied, memory foam softens to form around the natural curves of the body, relieving pressure points and reducing aches and pains. Memory foam beds run the risk of overheating, however, choosing memory foam with cooling properties, like breathable plant-based foam or gel memory foam regulates body temperature.

A typical memory foam mattress contains layers of foam including a comfort layer of memory foam and a support layer of high-density foam.

Innerspring

Innerspring coil mattresses are more commonly found in households. Known for their bouncy surface and cooling properties, innersprings have excellent edge support for those who prefer sleeping on the edge of the bed. Some drawbacks to an innerspring mattress include motion transfer, less pressure relief, and noise potential.

An innerspring mattress contains a thin comfort layer (usually in pillow top form) of fiberfill or foam and a support layer of steel innerspring coils.

Latex

Latex resembles memory foam by conforming to the body to relieve pressure points. Latex is more sponge-like, cooler, and more responsive than traditional memory foam. There are two types of latex: synthetic and natural. Synthetic latex is created through a chemical process, while natural latex is made from rubber tree sap.

Two types of natural latex commonly found inside mattresses are Dunlop and Talalay. Dunlop is 100% natural and is denser and more durable than Talalay. Talalay latex contains polyurethane fillers for its signature soft feel.

A latex mattress contains a comfort layer of latex and a support layer of either high-density foam or latex.

Hybrid

Hybrid mattresses combine pressure-relieving memory foam and responsive innerspring coils to form the perfect mattress. Hybrids offer the best of memory foam and innerspring, but they also come with drawbacks, like the risk of overheating and motion transfer. Plus, hybrids are heavier and more expensive than other mattress types because of the number of materials they contain.

A hybrid mattress contains a comfort layer of memory foam or latex and a support layer of pocketed coils.

Quality

To determine material quality, take a look at the foam’s ILD rating and density, and coil count and gauge.

Foam

ILD, or Indentation Load Deflection, evaluates the foam’s firmness by measuring how much pressure it takes to make a 4-inch indentation on the surface—the higher the number, the firmer the foam. ILD ratings range between 8 (softest) and 20 (firmest) in the comfort layer. Potential shoppers should look for a 10 ILD rating for the best comfort and support.

Density is how the foam supports the body, measuring how long it takes for the foam to spring back into its original shape. Many mattresses contain a mix of low- and high-density foams, depending on the brand.

  • Low-density: 2.5 to 3.9 PCF
  • Medium-density: 4.0 to 5.9 PCF
  • High-density: 5.5 PCF or higher

Coils

Coil count is the number of innerspring coils in a single layer. Quality mattresses contain between 500 to 1,000 coils. Avoid mattresses that contain 300 coils or less—these types of beds are more likely to breakdown within two years.

Coil gauge is the thickness of a coil. Measured in millimeters, coil gauge ranges between 12 millimeters (thickest) to 18 millimeters (thinnest). While thin coils are not a bad thing—they provide softer support—be wary of support layers containing only low-gauge coils, since they’re more likely to sag within a year.

Body Types

One major factor in finding the right firmness is body type. Your weight needs a certain balance of comfort and support for a good night’s sleep. Weight is divided into three groups—light, average, and plus-size.

Light

Light sleepers weigh less than 130 pounds. They need a softer surface to enable cushioning pressure relief.

Average

Average sleepers weigh between 130 to 230 pounds. A medium surface is a great choice—the perfect balance of comfort and support.

Plus-Size

Plus-size sleepers weigh more than 230 pounds. They need a firmer mattress to provide even support without risk of sagging.

Sleeping Position

Another major factor in choosing the right firmness is your favorite sleeping position. How you sleep determines how much cushioning and support your body needs for healthy spinal alignment.

Side Sleeping

Side sleeping is the healthiest sleeping position. It enables better breathing, reduces acid reflux symptoms, and improves heart health. Placing a pillow between the knees straightens the hips, preventing spinal misalignment.

Side sleepers need a soft to medium mattress for optimal pressure relief in the shoulders and hips and to fill in large gaps between the body and the mattress.

Back Sleeping

Back sleeping allows the spine to align naturally because of the back’s direct contact with the sleep surface. Risks involved with back sleeping include snoring and sleep apnea.

Back sleepers should look for a medium to firm mattress to cradle the hips and enhance lumbar support.

Stomach Sleeping

Stomach sleeping is one of the unhealthiest sleeping positions because of the amount of pressure placed on the spine. Heavy pressure can lead to neck strain and back pain, but placing a thin pillow under the hips can reduce this pressure. Alternatively, investing in the best mattress for back pain can prevent discomfort.

Stomach sleepers need a medium-firm to firm mattress to keep the body resting on top and prevent heavy sinkage.

Combination Sleeping

Combination sleepers, or restless sleepers, switch between 2 to 3 sleep positions each night. They receive all the benefits of each sleeping position, like improved heart health and natural alignment, but they also get the drawbacks, including snoring and neck strain.

Combination sleepers need a medium to medium-firm mattress to maintain alignment and for consistent comfort and support.

Sleep Trial, Return Policy, and Warranty

Sleep trials, return policies, and warranties are reassurances to the customer of a quality mattress purchase.

Sleep Trial

A sleep trial allows customers to try out a new mattress within the comfort of their own home. These trial periods usually last between 90 to 120 nights, with some mattress companies requiring their customers to keep the mattress at least 30 days to let the body adjust. If the customer doesn’t like the mattress, most online mattress companies will pick up and donate the bed before issuing a full refund.

Return Policy

A return policy is a good substitute if a mattress doesn’t come with a sleep trial. Most return policies last 30 days—about the same time it takes for the body to adjust to a new sleep surface. If the customer isn’t happy with the mattress, they can return it for a refund.

Warranty

Warranties cover any manufacturing defects which could damage the mattress and sagging greater than 1 inch (the measurement varies, depending on the brand). Most mattresses come with a standard 10-year warranty and only applies to the original purchaser.

FAQs

Which is better, foam or spring mattress?

Memory foam is the better choice because of its excellent pressure-relieving properties and ability to maintain its original shape.

Is it better to sleep on a hard or soft mattress?

The mattress firmness depends on your favored sleeping position and body weight. The right mattress contours to your body to relieve pressure points while evenly supporting your body for healthy spinal alignment.

Can a mattress cause back pain?

A mattress that is too firm, too soft, lumpy, or sagging can lead to back pain. You want a mattress that fits the “Goldilocks” standard with an even balance of comfort and support.

Conclusion

When looking for a new bed, consider an online mattress. Online mattress companies offer high-quality beds at lower costs—you won’t have to worry about pressure to buy, plus you get an extended sleep trial to try out a new mattress at home. The best online mattress is just a click away.
