Nectar and Allswell are both relatively new to the industry, but both companies have quickly gained popularity with their bed-in-a-box mattress options. Each company focuses on offering affordable, high-quality mattresses.

Nectar launched in 2017. While their product line has expanded to include bedding, bed frames, and sleep accessories, they only offer one mattress style: the Nectar mattress. This memory-foam mattress is backed by a 365-night trial and lifetime warranty. Nectar pairs premium materials with high-quality manufacturing practices, all while keeping overall cost and affordability in mind.

Allswell was launched in 2018 by Walmart. The company is focused on offering luxury mattresses and accessories at an affordable price point. The stylish aesthetic extends to their product line of bedding, throw blankets, and decorative pillows. Allswell offers three mattress styles: the Allswell; the Luxe; and the Supreme. For the purpose of this review, we focus on the Allswell Supreme mattress. The Supreme mattress is a luxury hybrid mattress with a plush Euro-top, comfort layers of memory foam, and a support base of pocketed innerspring coils.

Both of these mattresses offer optimal support and cushioning for a restful night’s sleep. Read on for our in-depth Allswell Supreme vs. Nectar mattress comparison.

Mattress Construction Comparison


The Nectar mattress is a memory foam mattress constructed of four separate layers of foam that balance comfort and support. The unique combination of layers is designed to have better temperature regulation and more bounce than traditional memory foam mattresses. The Tencel fabric cover is breathable with moisture-wicking properties.

The first layer of the Nectar mattress is 1 inch of quilted gel memory foam, which conforms to the shape of your body. The gel memory foam is more breathable than traditional memory foam, resulting in a cooler sleep.

The second layer is 3 inches of gel memory foam, which provides additional pressure point relief by contouring to the shape of your body and providing cushioning. This medical-grade foam has a density of 3.5 PCF.

Adaptive hi-core foam comprises the third layer of the Nectar mattress. This layer is more resilient than traditional memory foam, which adds bounce to the mattress.

The support layer of the Nectar mattress is 5.25 inches of breathable foam with a density of 2.2 PCF. This layer provides consistent support throughout the mattress.

Allswell Supreme

The Allswell Supreme is a hybrid mattress with a 5-layer construction. This mattress combines elements of a memory foam and innerspring mattress for a balance of cushioning and support.

The breathable cover of the mattress is soft and quilted. The built-in Euro-top is plush with a foam layer for added softness.

Underneath the plush Euro-top is a layer of cooling gel memory foam that is infused with graphite and copper. These added elements promote  temperature regulation by pulling heat away from the body, making this layer cooler than traditional memory foam.

The transition layer is 2 inches of Energex foam. This foam is engineered to be particularly responsive and provide pressure point relief and full-body support.

The support layer of the Supreme mattress is comprised of individually wrapped coils. This layer has a reinforced perimeter with Quantum Edge support. The pocketed coils minimize motion transfer while adding bounce and resilience to the mattress.

Firmness Comparison

Mattress firmness refers to how comfortable a mattress is and is determined by how soft or firm the mattress feels. It is also important to understand how mattress firmness and support differ. Support is measured by how well a mattress keeps your spine in alignment. Mattress firmness is determined by additional subjective factors including personal preference, body weight, and sleeping position.

Though mattress firmness is subjective, it is an important factor in deciding if a mattress is right for you. To simplify mattress firmness, it is typically referred to on a scale from 1 (extremely soft) to 10 (extremely firm). It is rare to find a mattress at either extreme on the firmness scale, and most mattresses tend to fall somewhere in the middle. Medium-firm mattresses offer pressure point relief and support for a combination of sleeping positions and are preferred by most sleepers.

The Nectar mattress has a combination of soft, contouring memory foam and high-density support foam. This unique combination results in a medium-firm feel that falls around a 6.0 on the firmness scale. This firmness is ideal for all sleeping positions, as it relieves pressure points with thick, cushioning layers of memory foam with enough support to promote spinal alignment.

The Allswell Supreme mattress is considered medium-firm. With a plush Euro-top and contouring layers of foam, the Supreme mattress falls around a 5.0 on the firmness scale. Allswell lists the firmness of the Supreme mattress between 4.5 and 6.5, as the plush Euro-top feels firmer for lightweight sleepers and softer for heavier sleepers. The Energex transition layer and innerspring support provide responsive support and contouring.

Sleep Experience

When selecting a mattress, it is important to take the following sleep experience elements into consideration. Temperature control, motion transfer, responsiveness, resilience, and edge support all contribute to how comfortable a mattress is. As the Nectar mattress and Allswell Supreme mattress differ in materials and construction, the overall sleep experience differs.

Temperature Control

Temperature control is essential to providing a comfortable night’s sleep. Whether a mattress feels warm or cool depends on the materials used. Softer mattresses that conform closely to your body can restrict airflow and trap body heat.. This is most common in memory foam mattresses. Innerspring mattresses tend to have superior air circulation due to the coil support layer.

The Nectar mattress has a Tencel fabric cover that wicks away heat and moisture. The quilted memory foam comfort layer is designed to promote airflow around the body. The second layer of gel memory foam absorbs and distributes heat for a cooler feel than traditional memory foam. The base layer of foam is also designed to be more breathable than most foam support cores. This combination results in enhanced temperature regulation for the  Nectar mattress and a cooler sleep than you’d find with an average memory foam mattress.

The Allswell Supreme mattress is softer, so airflow can be restricted if you sink into the mattress. However, the cover is quilted and breathable. In addition, the gel memory foam stays cooler, as it is infused with graphite and copper which pull heat away from the body. The coil support core also provides superior airflow and ultimately promotes cooling. The Allswell Supreme will sleep slightly cooler than an all-foam bed like the Nectar.

Motion Transfer

Motion transfer is an important consideration for those who share the bed with a partner. How well a mattress absorbs movement and prevents it from rippling throughout the bed is determined by the construction and materials used in the mattress. Memory foam tends to have excellent motion isolation, as it absorbs movement and prevents it from transferring. Innerspring mattresses tend to facilitate movement and have less motion isolation than memory foam.

The Nectar mattress includes 4 inches of memory foam. These thick layers absorb movement, so you should not be disturbed by your partner or pet’s movement throughout the night.

The Allswell Supreme mattress uses individually wrapped pocket coils in its support core, which helps to reduce the high level of motion transfer characteristic of traditional innerspring mattresses. An additional layer of memory foam also helps to reduce motion transfer, but in this category, the Nectar performs better.


Responsiveness is measured by how a mattress reacts to pressure. In order to provide proper support and keep your spine aligned, the mattress should respond proportionately to pressure points and the heaviest parts of the body, like the shoulders and hips. Memory foam is a responsive material, as it contours to the shape of your body to evenly distribute weight and cushion pressure points.

The Nectar mattress has thicker layers of memory foam for excellent contouring. The adaptive hi-core foam layer also provides supportive contouring.

The Allswell Supreme mattress has a layer of responsive memory foam, though it is underneath the plush Euro-top. This results in gentle contouring without the usual feeling associated with memory foam of sinking in or being “hugged” by the mattress. The combination of layers also provides adequate relief for most sleepers’ pressure points.

Resilience and Bounce

How quickly a mattress returns to its original shape when you move or leave the bed is referred to as resilience. Resilience and bounce in a mattress may be important considerations for couples, as these factors are best for sex. Mattresses with bounce tend to be better for moving around in general, whether for sex, repositioning overnight, or getting out of bed.. Memory foam absorbs movement and tends to return to its original shape slowly. This can inhibit movement. Innerspring mattresses have higher resilience and additional bounce. Since more bounce, often means more motion transfer, couples usually like a balance between these two factors and both of these beds strike a good one.

The Nectar mattress has more bounce than the average memory foam mattress, due to the adaptive hi-core foam layer. The medium-firmness of the mattress also prevents the feeling of sinking in or being stuck.

The Allswell Supreme mattress has plush comfort layers which have a lower resilience. The Energex foam used in the transition layer is resilient and prevents the feeling of sinking in too far or being stuck. The individually wrapped coils also contribute to the  bounce or springiness ofthe mattress.

Edge Support

Edge support in a mattress affects how the mattress holds up if you sleep or sit on the edge. A mattress with a reinforced perimeter has an increased sleepable surface area and stays firm when you sit on the edge of the bed. Memory foam mattresses do not typically have a reinforced perimeter, while hybrid and innerspring mattresses tend to have added edge support.

The Nectar mattress is designed to feel firm edge to edge. The high-density foam base provides additional support. As the comfort layers are thick memory foam, the mattress may sink in slightly if you sit on the edge of the bed.

The Allswell Supreme has a reinforced perimeter with Quantum Edge coils. These high-gauge coils around the perimeter of the mattress provide additional edge support. As the comfort layers are plush, the mattress may still feel soft if you sit on the edge of the mattress.

Off-gassing and Smell

Certain materials are more likely to off-gas when they are new. This smell can also be a result of the packaging used. Off-gassing is most common with memory foam mattresses and mattresses that are compressed and vacuum-sealed in plastic. This smell is not harmful and typically dissipates within a few days, faster when they’re allowed to air out without bedding on them for the first night.

Both the Nectar mattress and Allswell Supreme mattress are CertiPUR-US Certified and made without toxins. As both are bed-in-a-box styles, they are compressed and vacuum-sealed in plastic for shipment. This results in a faint off-gassing smell when the mattress is new. The smell dissipates quickly, especially in a well-ventilated room. At most, it could last up to a few days.


Shipping, Trial, Warranty, and Returns

Shopping online presents its own difficulties, as you are not able to see or feel the mattress before purchasing. Because of this, it is especially important to consider factors like the length of the sleep trial and the return policy. Information regarding shipping, sleep trial length, warranty length, and returns for both Nectar and Allswell are detailed below.
