MEET THE BROOKLYN BEDDING THERMOBALANCE LX ELITE MATTRESS

Firmness, Construction, and Performance

At The Drift, we take mattresses (and your sleep) seriously. That starts with what your bed is made of and how that translates to its feel and durability. Let's dive in.

Feel & Firmness

Firmness Level: Available in Soft, Medium, and Firm. The Soft is best for side sleepers and lighter body weights seeking maximum pressure relief. The Medium is the most broadly versatile option and the only firmness that includes an HD 4.0 Copper Memory Foam layer in the comfort system -- making it the most premium-feeling version of the three. The Firm is the right choice for back and stomach sleepers who need more hip and lumbar surface support. All three are in our showroom.
Feel Description: The surface has the familiar buoyant, responsive quality of Talalay latex in the comfort zone, but with a notable depth and structure below it that the standard LX doesn't match. The VX 2.5 Responsive Foam adds a secondary layer of responsiveness beneath the latex, making repositioning feel effortless. The dedicated lumbar support layer below that creates a subtle but meaningful firmness shift under the lower back that back sleepers will notice immediately. The Ascension Max coil base adds a final layer of deep compression support. The overall character is cool, responsive, and deeply structured.
Our Take: The ThermoBalance LX Elite's rating profile earns its position at the top of the ThermoBalance family. The 9.0 cooling score is the most striking single result -- among the highest we give any mattress -- and reflects the coordinated three-phase approach of ThermoCool, ThermoPhase PCM, and Talalay latex breathing together rather than a single feature doing all the work. Support at 8.5 directly reflects the dedicated zoned lumbar layer, which is a genuine structural addition over the LX. And ease of movement at 8.5 shows what Talalay latex and VX 2.5 Responsive Foam together produce at the comfort layer. This is a mattress that earns every premium claim it makes.

Construction & Materials

Height: 15.5"

Design: Nine-layer flagship latex hybrid with triple cooling technology, dedicated zoned lumbar support, and Ascension Max ultra-durable coil system. Available in Soft, Medium, and Firm. GREENGUARD Gold Certified, CertiPUR-US® certified. Fiberglass-free. Made in the USA.

Layer Breakdown (varies by firmness):

ThermoCool Cover: Cool tech fibers remove excess heat from the sleep surface for immediate, sustained cooling from first contact through the night.
ThermoPhase PCM Foam (0.75"): Phase change material absorbs excess body heat and releases it when temperature drops -- the second stage of the triple cooling system, operating throughout the night rather than just at the surface.
Quilt Foam (0.75"): Moisture-wicking quilt layer that adds breathability and surface comfort while resisting body impressions.
Comfort Foam Layer (varies by firmness):

Soft: 1" Talalay Latex -- buoyant and responsive, delivers natural pressure relief and open-cell airflow.
Medium: 1" HD 4.0 Copper Memory Foam -- copper-infused 4lb memory foam for premium pressure relief with antimicrobial and cooling properties. This is the most substantial comfort foam in any ThermoBalance model.
Firm: 1" Talalay Latex -- same as Soft, delivering responsive cushioning with firmer feel calibrated below.

VX 2.5 Responsive Foam (1"): A responsive 2.5lb foam layer that adds a secondary stage of quick surface response -- working alongside the latex or copper foam above it to make repositioning more effortless throughout the night. New to the LX Elite and not present in the standard LX.
Secondary Comfort Layer (varies by firmness):

Soft: 1" HD 3.6 Memory Foam -- contouring 3.6lb foam for pressure distribution.
Medium: 1" Talalay Latex -- positioned below the VX foam for buoyancy and structural cushioning.
Firm: 1" HD 3.0 Memory Foam -- 3lb memory foam for controlled contouring at a firmer feel.

Zoned Lumbar Support Layer (0.75"): The defining structural addition that separates the LX Elite from the standard LX. A targeted foam layer positioned under the lumbar region that promotes spinal alignment and relieves lower back pressure independently of the coil system's zoning. A genuine structural benefit for back sleepers and anyone dealing with lower back discomfort.
Ascension Max Coil System (8", up to 900 coils): Brooklyn Bedding's most durable encased coil system -- heavier-gauge coils than the standard Ascension, designed for long-term structural performance. Provides deep compression support, 360-degree airflow, and consistent edge support across the full perimeter.
Supportive Base Foam (1"): A thicker-than-standard base layer that stabilizes the Ascension Max system and supports the mattress's long-term structural integrity.

Why It Matters: The ThermoBalance LX Elite's nine-layer construction is engineered at each level with a specific job to do. The triple cooling system handles thermal management from surface to core. The dedicated lumbar support layer addresses lower back alignment through structure rather than relying solely on the coil system's zoning. The VX 2.5 Responsive Foam adds a secondary responsiveness layer that improves ease of movement beyond what latex alone achieves. And the Ascension Max coils provide a more durable long-term support foundation than the standard Ascension. Every added layer over the standard LX has a measurable performance rationale -- reflected directly in the ratings. GREENGUARD Gold and CertiPUR-US® certified throughout.

Our Ratings & Advice

We've tested over 1,000 mattresses in the last 10 years and helped serve better sleep to over 1 million shoppers. Our ratings are born out of lab-based testing and real world evaluations.

Performance Breakdown

Category	Our Rating	Summary
Pressure Relief	8 / 10	Strong. The combination of Talalay latex, responsive foam, and memory foam layers across all three firmnesses delivers solid, well-distributed pressure relief at the shoulders and hips. The Medium's HD 4.0 Copper Memory Foam gives it the deepest contouring of the three options -- the most compelling choice for side sleepers who want maximum pressure relief at the LX Elite level.
Cooling	9 / 10	Outstanding -- the highest cooling score we give in the ThermoBalance family and among the highest across our full showroom. The triple-phase system -- ThermoCool cover, ThermoPhase PCM, and Talalay latex open-cell breathability -- addresses temperature regulation at the surface, through the night, and through the comfort layer structure simultaneously. For hot sleepers, this is the most complete cooling system in the Brooklyn Bedding lineup.
Support	8.5 / 10	Excellent. The dedicated 0.75" Zoned Lumbar Support foam layer is what drives this score above the standard LX's 8.0. It provides targeted lower back support independently of the coil system's zoning, creating a two-layer lumbar support structure that back sleepers -- particularly those with lower back sensitivity -- will feel immediately. The Ascension Max coil base reinforces that foundation throughout.
Motion Isolation	8 / 10	Very good for a latex hybrid. The VX 2.5 Responsive Foam and memory foam layers absorb partner movement effectively before it reaches the Ascension Max coil system, and the individually encased coils prevent cross-surface transfer. A strong result for a mattress with Talalay latex in the comfort system.
Edge Support	8 / 10	Very good. The Ascension Max's heavier-gauge perimeter coils provide consistent, durable edge support across the full mattress surface. Sleeping near the side and sitting on the edge are both stable and comfortable -- meaningful for couples who use the full mattress width and for daily ease of getting in and out of bed.
Ease of Movement	8.5 / 10	Excellent. The combination of Talalay latex and VX 2.5 Responsive Foam in the comfort layer creates a two-stage responsiveness system -- latex for immediate buoyant rebound, VX foam for a secondary layer of quick response beneath it. The result is one of the most effortless repositioning experiences in our showroom. A standout for combination sleepers.

Sleep Position Ratings

Excellent, particularly in the Medium. The HD 4.0 Copper Memory Foam in the Medium firmness provides the deepest pressure relief available within the LX Elite lineup -- exceptional at the shoulders and hips for average-weight side sleepers. The Soft is the right choice for lightweight side sleepers under 130 lbs or those who want more latex-forward buoyancy. Heavier side sleepers above 230 lbs will find the lumbar support layer and Ascension Max coils provide better sustained alignment than most competing hybrids.

Outstanding. The dedicated zoned lumbar support layer is the key reason to choose the LX Elite over the standard LX for this sleep position. It targets the lower back directly and independently of the coil system, providing a level of lumbar focus that most hybrid mattresses achieve only through coil zoning. The Medium and Firm are both strong back-sleeper options depending on preferred surface firmness.

Good in the Firm option. The firmer surface, responsive foam layers, and zoned lumbar support combine for solid hip and lower back alignment for stomach sleepers at average body weights. Heavier stomach sleepers should test the Firm carefully in-store against a more strictly firm option.

Excellent. The 8.5 ease-of-movement score is the highest in the ThermoBalance family and reflects what two layers of responsive material -- Talalay latex and VX 2.5 Responsive Foam -- produce at the comfort level. Combination sleepers who have tested other hybrids and found repositioning effortful will notice the difference immediately..

Final Verdict

The Brooklyn Bedding ThermoBalance LX Elite is the most complete and highest-performing mattress in the ThermoBalance collection -- a nine-layer latex hybrid that outperforms both the standard ThermoBalance and the ThermoBalance LX across every category we measure. The 9.0 cooling score is the most compelling single result and reflects a triple-phase thermal management system that operates at the surface, through the night, and through the comfort layer structure simultaneously. The dedicated zoned lumbar support layer and Ascension Max coil system together produce the 8.5 support score. The Talalay latex and VX 2.5 Responsive Foam together produce the 8.5 ease-of-movement score. Every upgrade over the standard LX has a performance rationale, and every one shows up in the ratings.

Best For

✓ Hot sleepers who want the most advanced and coordinated cooling system in the ThermoBalance lineup
✓ Back sleepers and anyone with lower back sensitivity who will benefit from the dedicated lumbar support layer
✓ Combination sleepers who want exceptional ease of movement from a premium latex hybrid

✗ Those with latex allergies -- consult a medical provider before purchasing
✗ Sleepers who prefer the deep, slow enveloping feel of a pure memory foam mattress
✗ Stomach sleepers at heavier body weights who need a strictly firm, flat surface
