Product Description

Beautyrest® Harmony Lux, a premium mattress collection from Simmons Beautyrest, offers a choice between Premier Anchor Island and Exceptional Coral Island. The models provide good support, enhanced cooling, and sustainable comfort using ocean plastics as high-quality fabrics. The Harmony Lux line’s commitment to using recycled plastic waste as mattress fabric benefits marine life and appeals to eco-conscious shoppers, with each queen-sized bed helping to remove up to 60-100 plastic bottles from the oceans.

The Harmony Lux collection features premium pressure-relieving foams, advanced cooling systems, and more supportive coils, ensuring consistent body support and a refreshing sleeping experience. The support system, powered by T2 Pocketed Coil® Technology, offers more support and better motion isolation than the Harmony models. While both Anchor Island and Coral Island models prioritize cooling, the Coral Island series offers advanced features with three cooling layers, making it a higher-priced option.

This review will focus on the Harmony Lux Beautyrest mattress, delving into its construction, feel, support, comfort, cooling, and more. Continue reading to uncover the details.

Q1. What Is Unique About The Beautyrest Harmony Lux Mattress? Does It Provide Superior Cooling, Comfort, Back Support, And Pressure Relief?

Simmons Beautyrest® Harmony Lux is a luxury hybrid mattress collection featuring a contemporary design with cutting-edge coil technology and soft pressure-relieving foam layers. The mattress incorporates recycled plastic bottles, which would otherwise end up in different landfills, thus promoting environmental sustainability. Anchor Island and Coral Island present a range of firmness choices, including Plush, Medium, Firm, and Extra Firm. For those seeking added luxury, a Plush Pillow Top option is available at an additional cost of $400.


Beautyrest® Harmony Anchor Island and Coral Island sleep extremely cool. The mattress models come with advanced cooling technology unique in its category. Anchor Island incorporates InfiniCool™ Lux, a cooling layer just beneath the cover, and plant-based cooling materials, creating a sleeping environment that enables you to sleep cooler and ensures that you fall asleep faster and sleep deeper. Conversely, Beautyrest® Harmony Coral Island sleeps cooler than Anchor Island, including a three-layered cooling system including InfiniCool® MAX, plant-based cooling technology, and RightTempTM Wave cooling foam. Pocketed coils at the base of both models also support cooling by allowing greater airflow throughout the mattress.

Comfort & Pressure Relief

Beautyrest Anchor Island and Coral Island offer good pressure relief with Beautyrest® ActiveResponse™️ Memory Foam, which contours the body curves to relieve stress from sharp pressure points. In the Anchor Island model, the softer foams in the Pillow Top contour the shoulders and hips, allowing you to sink in for a restful night’s sleep. Coral Island constitutes two times more memory foam than Anchor Island, thus alleviating pressure points more effectively, offering superior comfort and a night of pain-free sleep. The foam layers in both models allow uniform distribution of the body weight, and the individually encased coils at the base keep the body alignment proper, thus ensuring complete rest and comfort.

Back Support

Beautyrest Anchor Island and Coral Island mattress boasts a multi-layered foam construction combined with a sturdy T2 Pocketed Coil™ Technology foundation, ensuring excellent back support when you lay down. The exclusive coil technology, unique to the Harmony Lux collection, consists of dual-strand coils that provide enhanced support precisely where needed most, making it an ideal choice for individuals experiencing discomfort or pain.

Firmness and feel are subjective, varying from person to person. Keeping this in mind, Beautyrest® Harmony Lux designed its collection with diverse firmness options, including Extra Firm, Firm, Plush, Medium, and Pillow Tops.

Material & Construction

Q1. What are the unique technology, design, and materials used in the construction of the Beautyrest Harmony Lux Mattress?

Simmons Beautyrest® Harmony Lux uses sustainable fabric, premium foams, and individually wrapped coils to create a luxurious and durable bed. The construction of both models of this mattress is similar, with slight differences in the comfort layers and cooling system. Both feature a plush sleeping surface crafted from plastic bottles collected from oceans. The recycled fabric from these bottles makes your bed feel softer and helps clean oceans with this initiative. Anchor Island uses 60 bottles, while Coral Island uses 100, making it more soothing and appealing.

Let’s discuss each model’s unique design and construction features.

Construction of Beautyrest Harmony Anchor Island Mattress

  • Layer 1: The top layer below the plush sleeping surface comprises InfiniCool® LUX and plant-based cooling materials. InfiniCool® LUX is a two-layered cooling system that feels cool to the touch and helps to fall asleep quickly and stay asleep all night.
  • Layer 2: The comfort layer incorporates high-quality memory foam, specifically the Beautyrest® ActiveResponse™ Memory Foam, which molds itself to the body, aiding in the release of tension from pressure points. The gentle embrace of the ActiveResponse Foam relieves discomfort associated with pressure, ensuring that you wake up each morning feeling refreshed and free from any discomfort or pain.
  • Layer 3: The support system of the mattress incorporates 1255 Series T2 Pocketed Coils, which offer comprehensive support for the entire body, ensuring comfortable sleep in any sleeping position. These coils are individually wrapped in fabric, effectively reducing motion transfer and making it easier to share the bed with a partner.
  • Layer 4: At the base of the mattress, you will find either AirCool® Foam or AirFeel® Foam (depending on the firmness level). These foams promote improved airflow within the mattress while contributing to pressure relief.

Construction of Beautyrest Harmony Coral Island Mattress

  • Layer 1: The top layer of the Coral Island mattress incorporates InfiniCool® MAX, a three-layered cooling system offering an exceptionally cool sleeping surface. This model also features another cooling layer of RightTemp™ Wave Foam, a highly conductive carbon-infused foam that helps heat dissipation and offers pressure relief.
  • Layer 2: Similar to Anchor Island, the comfort layer of this model consists of Beautyrest® ActiveResponse™ Memory Foam, which contours every curve of the body, offering enhanced pressure relief.
  • Layer 3: The mattress’s support comes from double-stranded 1255 Series T2 Pocketed Coils, which offer more support than traditional spring coils and significantly aid in dampening motion transfer.
  • Layer 4: The mattress’s foundation comprises either AirCool® Foam or AirFeel® Foam, depending on the desired firmness level. These foams improve airflow within the mattress, besides contributing to pressure relief.

Q1. How Would You Rate Beautyrest Harmony Lux Mattress From A Repositioning and Responsiveness Perspective? 


Beautyrest® Harmony Lux has a multi-layer construction comprising foam and pocketed coils. Memory foam is generally known to give you a trapped feeling, but the inclusion of encased coils gives bounce to the mattress, thus making it easier to move around or get in and out of bed. Coral Island features more memory foam than Anchor Island in the comfort layer; hence, you will find it difficult to adjust while changing sides or positions on this model.


Harmony Lux, like other Beautyrest models, is highly responsive. Double-stranded pocketed coils offer plenty of bounce, making it easier to move around. The coils adjust to your body movements independently, enhancing responsiveness.

Comfort, Back Support, Pressure Relief


Q2. How Would You Rate Beautyrest Harmony Lux Mattress For Providing Comfort And Pressure Relief To Sleepers?

Lux Harmony collection, with its hybrid construction, offers superior pressure relief and even body weight distribution. The comfort system in Anchor and Coral Island models comprises multiple foam layers, as discussed above, which cushion the neck, shoulders, and hips and reduce excess pressure from the spine. It offers excellent pressure relief to back sleepers, especially the Extra Firm model of the Coral Island. Sleepers preferring a softer feel can go for the Plush model.

Further, carbon-infused memory foam (RightTemp™ Wave Foam) helps in advanced pressure relief from the time you lay on the mattress as it conforms closely to your body, offering you personalized support in all sleeping positions. The T2 pocketed coils in the base are responsive and provide enhanced support by adapting to your body’s natural curves, thus keeping the spine appropriately aligned. This ensures you wake up in the morning with fewer aches and pains. AirCool® Foam and AirFeel® Foam at the base also add to your body support, relieving stress from the critical pressure points, thus allowing a comfortable night’s sleep.

Cooling & Temperature Control


Q3. How Would You Rate The Cooling And Overall Temperature Control Characteristics Of Beautyrest Harmony Lux Mattress?

Harmony Lux Beautyrest mattress has advanced cooling technology unique in its category, allowing for a cool and comfortable sleep. The cover is made of sustainable fabric, and the InfiniCool™ Lux & InfiniCool® MAX layer just beneath the surface (of Anchor and Coral Island models) creates a sleeping environment that not only enables you to sleep cooler but also ensures that you fall asleep faster and sleep deeper.

RightTemp™ Wave Foam in the comfort layers prevents heat from building up and coils at the base allow more air to flow into the interior of the mattress, thus preventing heat from accumulating in the base. AirCool® Foam and AirFeel® Foam further enhances the cooling sensation by increasing airflow in the mattress.

Motion Isolation and Sharing a Bed


Q4. Does Beautyrest Harmony Lux Mattresses Provide Reasonable Motion Isolation When Sharing A Bed With Others?

Motion isolation is one of the defining features of all Beautyrest models. The Lux Harmony collection is no exception. Its dual-stage coil design (T2 Pocketed Coil® Springs) encased in fabric cloth responds independently to any pressure, thus isolating motion to a great extent. However, since the coils are responsive, they offer bounce; therefore, your partner may feel some movement while you are getting in and out of bed. But memory foam in the comfort layers helps to cut down on motion significantly. Therefore, changing sides may not bother you or your partner much if you share the bed. Further, extra memory foam in Harmony Lux Coral Island makes this model better at isolating motion than Anchor Island.

Edge Support


Q5. How would you rate the edge support of Beautyrest Harmony Lux Mattresses?

Beautyrest® Harmony Lux mattress models perform average in edge support. T2 pocketed coils and memory foam layers make the mattress’s support system robust but do not prevent sinking and sagging along the edges. This makes sitting or lying near the edges a bit uncomfortable. The Plush Pillow Top variants of both models with more memory foam will compress to some extent under pressure, but the Extra Firm and Medium variants of the Coral Island model do not let you sink deep while sitting near the edges.

Recommendation based on sleeping style

Beautyrest® Harmony Lux mattresses have a wide selection of beds catering to the needs of almost all types of sleepers as it has offerings from an extra firm, medium to plush.

Side Sleepers

Side sleepers put pressure on their hips and shoulders; leading to pressure points. Hence, side sleepers prefer a mattress that would cushion their pressure points without sinking deep into the bed. Plush and Plush Pillow top options are suitable for lightweight side sleepers. The foam layers cushion the hips and shoulders, keeping the spine properly aligned, thus reducing pressure on the lower back. Those in the average-weight category can go for the Medium option, while heavyweight individuals will prefer the Extra Firm model of Coral Island.

Back Sleepers

Sleeping on the back is the prime position, as it maintains the natural posture, keeping the spine appropriately aligned. Contouring and support are essential for back sleepers. Lightweight back sleepers will love the comfort of Beautyrest Anchor Island’s Firm, Plush, and Pillow Top models. In contrast, average-weight back sleepers will get ample support and pressure relief from the Medium Coral Island. T2 Pocketed Coil® in the support core prevents the hips from sinking, keeping the spine aligned. Heavyweight sleepers may benefit from sleeping on the Extra Firm Coral Island as their bodies get adequate support, contouring, and firmness.

Stomach Sleepers

Stomach sleepers need a firm, supportive mattress to keep their hips and abdomen from sinking deep into the bed. Anchor Island’s Firm and Medium Pillow Top variants will be good options for light and average-weight stomach sleepers. At the same time, Extra Firm and Firm Pillow Top Coral Island will cater to the needs of heavy sleepers as the memory foam layers, in combination with pocketed coils, will allow the body to sink enough, keeping it uplifted with appropriate spinal alignment.

Combination Sleepers

Medium Pillow Top Anchor Island and Medium Coral Island will be suitable choices for combination sleepers, as they will find appropriate support and comfort in all sleeping positions.

So, the Beautyrest® Harmony Lux collection has a bed for everyone.
