Material & Construction
Q1. What are the unique technology, design, and materials used in the construction of the Beautyrest® Harmony Lux™ Carbon Mattress?
Beautyrest® Harmony Lux™ Carbon mattresses have various firmness options and price points. The thicker the mattress, the costlier it is. Other features like the pillow top with additional cushioning also add to the price. Depending on the model, the comfort layers may have slight differences; otherwise, the support system and the cover material is identical in almost all models.
Each mattress model features a cover made from recycled ocean plastic waste (Seaqual™ Sustainable Fabric), which is a sustainable fabric, especially loved by environment-conscious people. In partnership with Seaqual™, Beautyrest has made it possible to use this sustainable fabric in its mattresses, making them durable and luxurious, thus helping to clean oceans with this initiative. Each mattress sold adds to the cleaning of oceans and supports marine life. Beneath the cover is a layer of foam (InfiniCool™ Lux) that feels cool to touch, offering a sleeping surface that helps to fall asleep quickly and stay asleep. The use of Beautyrest® Gel Memory Foam and RightTemp™ Wave Foam in the comfort layers helps in enhanced pressure relief for those suffering from aches and pains. The gel memory foam helps to sleep cooler compared to ordinary memory foam and also aids in relieving pressure points by contouring your body’s natural curves. RightTemp™ Wave Foam with carbon-infused fibers offers consistent support and relaxed sleep night after night. The base of each model is made of double-strand pocketed coils (T2 Pocketed Coil™ Technology) and BeautyEdge®, which makes the mattress supportive in different sleeping positions.
Let’s discuss each model’s unique design and construction features.

Q1. How would you rate Beautyrest® Harmony Lux™ Carbon Mattress from a repositioning & responsiveness perspective?
The coils in the support core of the Beautyrest® Harmony Lux™ Carbon mattress offer plenty of bounce, making it easier to move around. The design of each Harmony Lux™ Carbon mattress model using foam in multiple layers and pocketed coils make the mattresses extremely responsive. The materials help to regain the mattress shape quickly, reducing the trapped feeling in the bed.
Comfort, Back Support, Pressure Relief
Q2. How would you rate Beautyrest® Harmony Lux™ Carbon Mattress for providing comfort and pressure relief to sleepers?
Beautyrest® Harmony Lux™ Carbon mattress, with its hybrid construction, offers superior pressure relief and even body weight distribution. The comfort system in each model 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 Classic Top. Sleepers preferring a softer feel can go for the plush model.
Gel-infused memory foam (Beautyrest® Gel Memory 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 aid in providing 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. BeautyEdge® at the base also adds to your body support and allows you to sleep near the edges without the fear of rolling off.
Cooling & Temperature Control
Q3. How would you rate the cooling and overall temperature control characteristics of Beautyrest® Harmony Lux™ Carbon Mattress?
Hybrid mattresses regulate temperature better than all-foam models. The Beautyrest® Harmony Lux™ Carbon mattress comes with advanced cooling technology unique in its category, allowing for a cool and comfortable sleep. Cover made of Seaqual™ Sustainable Fabric and InfiniCool™ Lux layer just beneath the covers creates a sleeping environment that not only enables you to sleep cooler but also ensures that you fall asleep faster and sleep deeper.
Beautyrest® Gel Memory Foam prevents heat from building up in the comfort layers, and coils at the base allow more air to flow into the interior of the mattress, thus preventing heat from building up in the base. GelTouch® Foam in the plush version of both Classic and Pillow Top makes the mattress surface feel cool on touching, ensuring a cooler surface to sleep on.
Motion Isolation and Sharing a Bed
Q4. Does Beautyrest® Harmony Lux™ Carbon Mattress provide reasonable motion isolation when sharing a bed with others?
Beautyrest® Harmony Lux™ Carbon mattress does not fair very well in this category. The pocketed coils at the base are responsive, but being individually encased, they respond independently to any pressure, thus isolating motion to some extent. Memory foam of different thicknesses in the comfort layers helps to cut down on motion. Therefore, changing sides may not bother you or your partner much if you share the bed with your partner. However, while getting in and out of bed, some movement might be felt by either of you, as the T2 pocketed coils are responsive and bouncy. More memory foam in the comfort layers of the Pillow Top makes these mattresses better at isolating motion than the Classic Top.
Q5. How would you rate the edge support of Beautyrest® Harmony Lux™ Carbon Mattress?
Beautyrest® Harmony Lux™ Carbon mattress model comes with superior edge support. T2 pocketed coils along with BeautyEdge® make the mattress’s support system robust, preventing sinking and sagging along the edges. This makes sitting or lying near the edges feel safe. The plush Pillow Top with more memory foam may compress to some extent under pressure, but the extra firm and medium Classic Top versions do not let you sink deep while sitting near the edges.
Recommendation based on sleeping style
The Beautyrest® Harmony Lux™ Carbon mattresses have a wide selection of mattresses catering to the need 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; thus, these areas press against the mattress leading to pressure points. Hence side sleepers prefer a mattress that would cushion their pressure points without sinking deep into the bed. Plush models of the Classic and Pillow top options will be a good choice for side sleepers of lightweight. The foam layers would 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-firm mattress of the Beautyrest® Harmony Lux™ Carbon, and heavyweight individuals will prefer the extra firm model of the Classic Top.
- Back Sleepers: Sleeping on the back is the prime position to sleep, as it maintains the natural posture, keeping the spine appropriately aligned. Contouring and support are essential for back sleepers. Light weight back sleepers will love the comfort offered by the plush version of the Classic and Pillow Top mattress, while average weight back sleepers will get ample support and pressure relief from the medium-firm versions. T2 Pocketed Coil® and BeautyEdge® in the support core prevent the hips from sinking, keeping the spine aligned. Heavyweight sleepers may benefit from sleeping on the extra firm variant of the Classic Top 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. Light and average-weight stomach sleepers will sleep better on the extra firm variant of the Classic top, but those above 230 pounds will need to explore other options from the Beautyrest catalog.
- Combination Sleepers: Combination sleepers keep changing positions; thus, they need a good, responsive mattress. With varied firmness and comfort options offered by the Beautyrest® Harmony Lux™ Carbon mattress, combination sleepers have an exhaustive list to choose from as per their need and preference. Pocketed coils along with BeautyEdge® in each mattress support the body in all sleeping positions.
