MEET THE BROOKLYN BEDDING THERMOBALANCE LX 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 the right starting point for side sleepers and lighter body weights. The Medium is the most broadly versatile option and where most combination sleepers land after testing all three. The Firm suits back and stomach sleepers who need more hip and lumbar support. All three are available in our showroom.
Feel Description: The Talalay latex layer is what makes the LX feel different from the standard ThermoBalance. Where copper-infused memory foam contours slowly and cradles, latex responds immediately and pushes back with a buoyant lift. The ThermoCool cover is cool to the touch, and the ThermoPhase foam beneath it sustains that cooling through the night. The HD memory foam and VariFlex transition layers bridge the latex and the coil core, keeping the overall feel balanced -- responsive and cooling at the surface, structured and supportive below.
Our Take: The ThermoBalance LX's four categories at 8.0 -- cooling, support, motion isolation, and ease of movement -- reflect a mattress that executes its core proposition very well. The addition of Talalay latex lifts the ease-of-movement score above what the standard ThermoBalance achieves and adds a natural breathability that complements the PCM cooling system. Pressure relief at 7.5 is the modest step down from the standard model's 8.0, which reflects the trade-off of latex's buoyancy over the deeper contouring of denser copper memory foam. For sleepers who prioritize responsiveness and cooling above deep contouring, the LX is the more compelling choice within the ThermoBalance family.

Construction & Materials

Height: 14"

Design: Eight-layer latex hybrid with ThermoCool cover, ThermoPhase PCM, and Talalay latex comfort system. Available in Soft, Medium, and Firm. GREENGUARD Gold Certified, CertiPUR-US® certified. Fiberglass-free. Made in the USA.

Layer Breakdown:

ThermoCool Cover: Cool tech fibers woven into the cover fabric 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 infused into the foam absorbs excess heat and releases it when body temperature drops -- active thermal regulation rather than passive cooling.
Quilt Foam (0.75"): A moisture-wicking quilt layer that adds breathability, surface comfort, and body impression resistance.
Talalay Latex (1"): The defining layer that separates the LX from the rest of the ThermoBalance lineup. Talalay latex delivers a buoyant, responsive feel that cushions pressure points with a light, lifting quality rather than the slow sink of memory foam. Its open-cell structure promotes natural airflow, adding a third cooling mechanism alongside the ThermoCool cover and ThermoPhase PCM. Hypoallergenic and naturally antimicrobial.
HD 3.0 Memory Foam (1"): A 3lb high-density memory foam layer that adds contouring beneath the latex to fill in and cushion pressure points more precisely, particularly at the shoulders and hips.
VariFlex Transition Foam (1"): A responsive transition layer that bridges the comfort system and the coil core, enhancing contouring effects while providing balanced support between the two systems.
8" Ascension Zoned Coil Core (up to 1,032 coils): Individually encased coils with three-zone lumbar support built into the coil configuration -- firmer center coils under the lumbar region, softer zones at the head and foot. Reinforced perimeter coils for consistent edge support. 360-degree airflow through the support core.
Base Foam (0.75"): Foundational support layer that stabilizes the coil system and supports long-term durability.

Why It Matters: The ThermoBalance LX's cooling system operates on three distinct levels: the ThermoCool cover handles surface heat at first contact, the ThermoPhase PCM manages sustained heat accumulation through the night, and the open-cell Talalay latex adds natural passive airflow through the comfort layer. This is a more layered thermal approach than relying on copper-infused foam alone, and the combination shows up in the 8.0 cooling rating. The latex layer also shifts the feel profile meaningfully -- adding a responsiveness that improves ease of movement and creates a surface character distinct from any foam-only mattress. 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	7.5 / 10	Good to very good. The Talalay latex and HD memory foam layers provide solid pressure relief at the shoulders and hips across all three firmness levels. Slightly below the standard ThermoBalance's 8.0, which reflects the trade-off of latex's buoyant lift over the deeper contouring of denser copper memory foam. Best pressure relief performance in the Soft option.
Cooling	8 / 10	Excellent. The layered triple-cooling approach -- ThermoCool cover, ThermoPhase PCM, and Talalay latex's open-cell breathability -- delivers sustained, coordinated temperature regulation throughout the night. Latex's natural airflow adds a meaningful cooling contribution that pure foam-layer systems can't replicate.
Support	8 / 10	Very good. The Ascension Zoned Coil core's lumbar zoning combined with the VariFlex transition layer provides solid spinal alignment across sleep positions and body weights. Three firmness options allow more precise calibration of surface support than a single-firmness option allows.
Motion Isolation	8 / 10	Very good for a hybrid with a latex layer. The HD memory foam and VariFlex transition layers absorb a meaningful amount of partner movement before it reaches the coil system, and the individually encased coils prevent cross-surface transfer. Latex is typically associated with more motion transfer than memory foam, but the foam layers surrounding it here manage that effectively.
Edge Support	7.5 / 10	Very good. The reinforced Ascension perimeter coils provide consistent edge support across the full mattress surface. Comfortable for sleeping near the side or sitting on the edge -- a practical benefit for couples who use the full mattress width.
Ease of Movement	8 / 10	Excellent. The Talalay latex layer is the key contributor here. Latex's fast, responsive rebound makes repositioning noticeably more natural than a foam-only comfort system, which is reflected in this being one of the higher ease-of-movement scores among the ThermoBalance models. A meaningful advantage for combination sleepers.

Sleep Position Ratings

Very good, especially in the Soft and Medium. The latex and memory foam combination delivers solid pressure relief at the shoulders and hips without the slow, enveloping quality of a purely foam-dominant system. Lightweight side sleepers will find the Soft the strongest option. Average-weight side sleepers will do well in Medium. Heavier side sleepers above 230 lbs should compare with the ThermoBalance LX Elite, which adds a dedicated lumbar support layer.

Excellent. The Ascension Zoned Coil's lumbar zone and the firmer options make this one of the more complete back-sleeper hybrids in our showroom. The Medium works for most average-weight back sleepers; the Firm adds more hip resistance for heavier body weights.

Good in the Firm option. The firmer surface and responsive latex layer provide solid hip support for stomach sleepers at average body weights. The Soft and Medium may allow more hip sink than heavier stomach sleepers need for proper alignment.

Excellent. The 8.0 ease-of-movement score and Talalay latex's responsive character make this one of the best options in our showroom for sleepers who shift positions throughout the night. All three firmness options support easy repositioning well.

Final Verdict

The Brooklyn Bedding ThermoBalance LX is the most responsive and naturally breathable option in the ThermoBalance family -- a latex hybrid that earns 8.0 across cooling, support, motion isolation, and ease of movement while delivering a feel profile that stands apart from standard foam hybrids. The Talalay latex addition is not a cosmetic upgrade -- it meaningfully changes how the mattress responds to movement, how it breathes, and how the overall sleep experience feels night to night. For combination sleepers, hot sleepers who want layered natural cooling, and anyone drawn to latex's distinctive character, the LX is a compelling and well-executed step up from the standard ThermoBalance.

Best For

✓ Combination sleepers who want a premium cooling hybrid with latex's responsive, buoyant feel
✓ Hot sleepers who want Talalay latex's natural breathability layered into a triple PCM cooling system
✓ Back and side sleepers at average body weights who want balanced pressure relief and support with a responsive surface
✓ Couples who want strong motion isolation alongside a more lively, latex-forward feel
✓ Those who have tried foam hybrids and want something more responsive without sacrificing cooling or support

Not Ideal For

✗ Sleepers who want the deepest possible contouring and pressure relief -- the standard ThermoBalance's copper memory foam system goes deeper here
✗ Heavier side sleepers above 230 lbs who may benefit from the LX Elite's dedicated lumbar layer
✗ Those with latex allergies -- consult a medical provider before purchasing
✗ Stomach sleepers at heavier body weights who need an extra-firm surface
✗ Sleepers who prefer the slow, enveloping feel of memory foam over latex's responsive character
