Nectar vs Amerisleep Overview

The Nectar is a softer mattress built from a combination of foams. Overall, the bed is slow-responding and should offer sleepers that classic memory-foam experience.

Amerisleep offers sleepers a variety of firmness options across their five all-foam beds. The beds are conveniently numbered and range in firmness level from extremely firm (AS1) to luxuriously soft (AS5).

Who Should Get The Nectar

  • Back sleepers of light or average weight
  • Side sleepers of light or average weight
  • Those who love a softer bed
  • Anyone on a budget, as the bed is more affordable than Amerisleep

Who Should Get Amerisleep

  • Anyone who wants a variety of firmness options to choose from
  • Couples who want a bed with good motion-transfer results
  • Fans of memory foam mattresses. Even with the different firmness levels, Amerisleep offers a distinct sleeping experience that’s different from a hybrid bed.

Firmness and Feel Differences

Let’s see how these two beds compare in firmness and feel—arguably the two most important factors when purchasing a new mattress.

How Firm Are The Nectar & Amerisleep Mattresses?

Because it’s just one bed, the Nectar’s firmness is fixed at a 6.5/10. That places it in the Medium Firm category, with the top layer starting off soft and each layer beneath getting progressively firmer.

The respective firmness of Amerisleep’s beds are as follows: the AS1 is a firmer-than-average 8/10. The AS2 stays in the same category at a 7.5/10, and then we get into the Medium Firm range with the AS3, which scores a 6.5/10. The two softest models are the AS4 (6/10) and the AS5 (5.5/10).

Sleeping On The Nectar And Amerisleep Mattresses

The Nectar feels great on the back, with the memory foam layers conforming to the curves of the body. There’s also good overall support and lumbar support coming from the base layer. For side-sleeping, there’s just a little bit of pressure on the shoulders and hips, although that might vary depending on the sleeper’s weight.

Nectar Mattress - Side Sleeping

The mattress also might be too soft for stomach sleepers, who usually need more support across their entire body. Finally, we should note that the Nectar’s plushness and contouring make it one of the best mattresses for arthritis.

Because Amerisleep has five models to choose from, sleeping positions can get a bit complicated. We’ll lay it out for you in the simplest terms:

Stomach sleepers will be most comfortable on the firmness of the AS1, with the AS2 being the second-best option. Back sleepers should also be comfortable on the AS2, but are probably best suited for the AS3. Side sleepers will want to check out the softer beds such as the AS3 and AS5. But the absolute best option for side-sleeping is probably the AS4, its 4” layer of Bio-Pur foam allowing a lot of sinkage with almost no pressure on the shoulders or hips.

Amerisleep AS3 - Back Sleeping

What Do The Nectar And Amerisleep Mattresses Feel Like?

Because both mattresses are made entirely out of foam, they create a traditional slow-moving feel. They’re not super responsive, allowing sleepers to gently sink into them.

However, because Amerisleep’s models feature different amounts of Bio-Pur foam, there’s a bit more variety in terms of texture and feel.

Average-Weight Sleepers – 130lbs – 230lbs

On the Nectar, average-weight side and back sleepers should have the proper amount of support and comfort. The soft memory foam should especially appeal to those with hip pain. Average-weight stomach sleepers will likely need a more supportive bed overall, although the Nectar is one of the best mattresses for teenagers who sleep on their backs and stomachs.

For Amerisleep, average-weight back sleepers will probably feel the best balance of comfort and support on the AS3. Those who want a bit more support should feel right at home on the AS2. Average-weight side sleepers might enjoy the AS4 or the AS5 if they’re closer to 230lbs. Average-weight stomach sleepers will need a lot of firmness, so the AS1 is the best pick for them.

Heavyweight Sleepers – Over 230lbs

Because of its softness, the Nectar might not be the best option for heavier sleepers. The one exception might be heavier back sleepers, although those who are closer to and over 300 lbs might need something more supportive with coils in its construction.

Conversely, some of Amerisleep’s firmer models could get the job done. The AS1 and AS2 models are the best fits for heavier back sleepers, and heavier side sleepers should find the right amount of cushioning on the AS4 or AS5. Heavier stomach sleepers will definitely want to opt for the AS1, but depending on their exact weight, they still might need something more supportive.

Lightweight Sleepers – Under 130lbs

As with most memory foam mattresses, lightweight back and side sleepers should be comfortable and supported on the Nectar. Depending on their weight, lightweight stomach sleepers might need a firmer mattress.

When choosing an Amerisleep bed, lightweight back sleepers will want a mattress that’s not too firm. Otherwise, their hips won’t sink in the right amount. Their best options are probably the AS3 or AS4. Lightweight side sleepers will likely find the pressure relief they need on the AS3, AS4, or AS5. Finally stomach sleepers will probably feel most at home on the AS1 or AS2.

Mattress Construction Differences

The devil is in the details, so let’s get nitty gritty and break down the construction of each of these beds.


The Nectar’s cover is made of polyethylene—a breathable material that helps the top of the mattress stay cool.

All of the Amerisleep mattresses have the same cover of a lightweight, breathable material called celliant.

Comfort Layers

On the Nectar, you’ll first encounter a layer of gel foam that isn’t very responsive and takes a few moments to reform under pressure. The gel infusion is designed to fight against the heat-trapping nature of memory foam and give some extra cooling to the top of the mattress.

Nectar Classic Mattress - Construction

Next, there’s a layer of Soft Conventional Foam that has a higher density and is firmer than what’s above. That means it also serves as a transition layer to the support layer underneath.

Going over each individual comfort layer of all five Amerisleep beds would be too much for one mattress comparison to contain, but know that each mattress relies on Bio-Pur Foam, a plant-based material designed to be more breathable and responsive than regular memory foam. With the exception of the AS4 to the AS5, the Bio-Pur Foam gets thicker as the beds progress and get softer.

Amerisleep AS3 - construction and foam layers

The Bio-Pur Foam also works in tandem with other materials. For instance, the AS3 has a HIVE transition layer and the AS5 has a soft and bouncy material called Active Flex. We’ll once again point you to our full Amerisleep mattress review for the exact details of each layer.

Support Layer

The Nectar has a thick layer of high-density base support foam. Amerisleep’s support layers all use a dense proprietary material called Bio-Core foam. With the exception of the AS1, whose support layer is 8,” all of the Amerisleep beds have a 7” support layer.

Mattress Height

The Nectar is 12” tall, and the Amerisleep varies from model to model. The AS1 is 10” tall; the AS2, AS3, and AS4 are all 12” tall, and the AS5 is a whopping 14” tall.

Nectar And Amerisleep Performance Differences

Usually, we frame this category as a kind of contest where we evaluate which bed does best in a variety of performance tests. But because Amerisleep has so many beds to choose from, we’ll instead describe how the Nectar does in each area, then talk about which Amerisleep mattress (or mattresses) might perform best in that same area.

Sleeping Hot or Cold

Memory foam naturally traps heat, so especially hot sleepers might experience this on the Nectar. That being said, we didn’t experience this ourselves and found that the cooling cover and gel-infused memory foam did a nice job at regulating the bed’s temperature. Likewise, all of the Amerisleep mattresses tended to sleep cool.

Motion Transfer

The Nectar uses a slow-moving foam that we found to be especially good at isolating motion. Amerisleep’s Bio-Pur has a similarly slow responsiveness, so the beds that have more of it tended to fare best with motion transfer. The AS4 and AS5 would probably be the best Amerisleep beds for couples.

Edge Support

Memory foam isn’t usually known for its strong edge support, so we were pleasantly surprised to find that the Nectar scored well here. We were able to sit on the edge of the bed and tie our shoes with no collapse on the mattress.

Nectar Classic Mattress - Edge Support

Amerisleep varies in this category. The firmer beds expectedly provided better edge support, with the AS1 and AS2 being the best options. When lying down on the softer models, we didn’t feel very supported when close to the edge of the bed.

Amerisleep Mattress - Edge Support


Both the Nectar and Amerisleep beds are all-foam mattresses with denser materials at the base. They should last seven to 10 years with little issue.


Off-gassing is just another word for the faint smell that emerges when opening and unrolling any bed-in-a-box mattress. With both Nectar and Amerisleep, it went away after 48 hours. Placing the mattress in a well-ventilated room can further expedite the process.


Because all of these beds are made entirely of foam, there shouldn’t be any noticeable noise when moving around.


If you’re looking for one of the best mattresses for sex, memory foam usually isn’t the best material, as its sinkage can make it difficult to move around. While the Nectar and softer Amerisleep models likely won’t fit the bill, the firmer and more responsive AS1 and AS2 mattresses could do quite well here.

Company Policies

Before you make your final purchasing decision, make sure to take a look at the company policies!

Warranty Info

The Nectar has a forever warranty and the Amerisleep beds all have a 20-year warranty.

Sleep Trial

The Nectar’s sleep trial period is a full year, while Amerisleep’s is 100 nights.

Return Policy

If sleepers are unsatisfied with their Nectar purchase, they can return it for a full refund, not including shipping fees, White Glove Service, state-based recycling fees, and/or promotional value. See Nectar’s website for details.

Amerisleep requires customers to sleep on their mattress for at least 30 nights, after which they can request a full refund if they’re not satisfied with their product. If anyone would like a refund before the 30-day wait period, they’ll be charged a $99 early processing fee. Rather than return the mattress to Amerisleep, the company asks that customers donate their bed to a local organization or charity. See Amerisleep’s website for more details.

Because of the sturdy materials and lengthy warranties, you can rest assured that each of these beds are designed to last years and years.
