YAWNDER MATTRESS REVIEW
Review method: This guide evaluates Brooklyn Bedding’s published specifications and terms. It does not report a hands-on test of the ThermoBalance LX Elite. Prices and policies can change.
Our Verdict
The Brooklyn Bedding ThermoBalance LX Elite is a premium hybrid to consider if you want Talalay latex alongside foam, a choice of firmness and a substantial mattress profile. Its distinguishing features include a separate zoned lumbar foam layer and an Ascension Max coil system. It is best evaluated against the less expensive LX in the same size and firmness: a taller, more elaborate construction may appeal to you, but its value depends on your comfort and the price difference.
The Elite uses passive cooling materials, not a powered cooling system. We have not measured its overnight temperature, edge support, partner disturbance or durability.

Who Should Consider It?
- Shoppers who want to choose among three firmness levels in a latex-containing hybrid.
- People interested in a taller mattress with quilted foam and a separate lumbar layer.
- Buyers deciding between the LX and LX Elite who can compare the same firmness and size.
- Partners willing to use the trial to assess comfort, motion and edge support together.
Who Might Prefer Another Mattress?
- Shoppers looking for an all-latex or foam-free mattress: the Elite contains several foam layers.
- Anyone with a low bed-height requirement: check the combined height of the mattress, foundation and frame.
- Buyers seeking active cooling, a certified organic mattress as a whole, or a proven medical treatment.
- People sensitive to latex should check the product materials and consult a qualified clinician about their situation.
Construction and Materials
Brooklyn Bedding describes a ThermoCool cover, ThermoPhase foam, quilt foams, Talalay latex, responsive foam and memory foam. A zoned lumbar support layer sits above an 8-inch Ascension Max coil unit and base foam. The manufacturer lists different layer orders and foam specifications for the three firmness options. Check the specific configuration when ordering.
Latex can provide a more buoyant response than slow-moving memory foam, but this model includes both materials and its overall feel depends on the entire stack. The lumbar layer is designed to change support around the middle of the mattress; how that feels depends on where your body contacts it.
How the three firmness stacks differ
Brooklyn Bedding publishes a separate layer order for Soft, Medium and Firm. Each uses a ThermoCool cover, ThermoPhase foam, quilt foams, a 1-inch Talalay latex layer, responsive foam, memory foam, a 0.75-inch zoned lumbar layer, 8-inch Ascension Max coils and base foam. The following differences are manufacturer specifications, not Yawnder firmness measurements.
| Option | Published layer distinction | How to approach the choice |
|---|---|---|
| Soft | Latex above responsive foam and 3.6 lb/ft³ memory foam | Consider if shoulder and hip cushioning is a priority; check whether the surface gives enough for your body. |
| Medium | 4.0 lb/ft³ copper memory foam above responsive foam and latex | A starting point for a shared bed or mixed positions, provided both partners find it comfortable. |
| Firm | Latex above responsive foam and 3.0 lb/ft³ memory foam | Consider if you prefer a firmer surface; test pressure as well as hip support. |
Foam density is a material specification, not a firmness rating. The order of latex and memory foam can influence the surface feel, but the whole mattress, body weight and sleeping position matter. Do not infer that the higher-density Medium foam makes that version firmer or longer-lasting than either alternative.
Choosing Soft, Medium or Firm
Soft
Soft is a starting point for side sleepers seeking more cushioning around the shoulder and hip. Lighter sleepers often compress a mattress less, so check that the surface actually relieves pressure instead of choosing by name alone.
Medium
Medium may appeal to back sleepers and couples seeking a compromise. Each person should test their usual position and assess both pressure and support. A medium label is not a standardized measurement across brands.
Firm
Firm is worth trying if you prefer less surface give or sleep mainly on your stomach. Pay attention to hip position and comfort; the firmest option is not automatically the best fit.
What the layer details mean
Brooklyn Bedding’s published Soft configuration lists a 1-inch Talalay latex layer, a 1-inch responsive foam layer, a 1-inch memory-foam layer and a ¾-inch zoned lumbar foam layer over an 8-inch Ascension Max coil unit. The company lists the Soft memory foam at 3.6 pounds per cubic foot. Its other firmness descriptions use different foam specifications, so check the exact configuration instead of applying one stack to all three. These figures are manufacturer specifications, not independently measured results.
At the listed 15.5-inch profile, the Elite adds 1.5 inches to the height of the 14-inch LX before accounting for either foundation. Measure the complete bed height and check that sheets and protectors fit. Brooklyn Bedding identifies its foam as CertiPUR-US certified; that designation applies to eligible foam and does not certify the whole mattress as organic.
Cooling, Motion Isolation and Edge Support
The cover and foam are marketed for temperature regulation. Cool-to-the-touch fabric can feel different at bedtime than after several hours under blankets, and the system does not actively circulate cooled air. Try it with the sheets and protector you normally use.
The latex, foam and coil combination may affect how movement travels across the mattress, but construction alone cannot establish a test result. When sharing a bed, have one person roll over while the other lies still. Sit and lie near the edge as well, especially if you rely on the perimeter to get in and out.
ThermoBalance LX Elite vs. ThermoBalance LX
| Feature |  LX |  LX Elite |
|---|---|---|
| Listed profile | 14 inches | 15.5 inches on the brand’s comparison card |
| Firmness | Soft, Medium, Firm | Soft, Medium, Firm |
| Support design | Ascension zoned coils | Ascension Max coils plus a separate zoned lumbar foam layer |
| Shared features | Talalay latex and cooling-oriented materials | Talalay latex and cooling-oriented materials |
The Elite’s additional height and lumbar layer do not prove it will be more comfortable or durable. Check the price difference for your size and the feel you intend to buy; promotions can alter the gap. Read our ThermoBalance LX review for the other model’s details. Neither page reports a hands-on test of these specific models.
Price, Delivery, Trial and Warranty
Choose the size and firmness before comparing the final price. Sale prices and delivery options can change, and retailer terms may differ from those offered directly by Brooklyn Bedding.
Brooklyn Bedding’s current product and return pages advertise a 365-night direct trial. Some cached product and collection pages have also displayed 120 nights, so confirm the current trial for the exact model before purchasing. Its product page says to allow at least 30 days after delivery before beginning a return; it also describes limits on use of the trial and excludes clearance items from returns or exchanges. Confirm the current policy, eligibility, applicable fees and handling of delivery charges before ordering. See our Brooklyn Bedding return policy guide for a closer look at trial terms.
The brand advertises a limited lifetime warranty. Read the actual warranty for covered defects, exclusions, foundation requirements and claim procedures. A warranty does not guarantee comfort for life.
Fit, Setup and Daily Use
Before ordering, measure the entire setup: floor to top of frame or foundation, plus the mattress’s listed 15.5-inch profile. Sit on a bed at a similar height if getting in and out is a concern. Check that your fitted sheet and protector have enough depth to wrap under the mattress, particularly if you add a topper.
Brooklyn Bedding describes boxed delivery and recommends a solid, minimally flexible foundation; its product FAQ permits slatted bases with gaps no greater than 5 inches. Confirm the current foundation and warranty terms for your size and frame. Plan for help carrying and positioning a large hybrid. The brand says most of its mattresses should be rotated every 6 to 8 months and not flipped; confirm the care instructions supplied with your mattress.
How to Evaluate the Mattress at Home
Pressure and support: Use your usual pillow and lie in each position you normally sleep in. Side sleepers can notice shoulder and hip pressure; back and stomach sleepers can pay attention to comfort around the hips and lower back. A different firmness label is only a starting point, and a zoned layer does not guarantee that every body lines up with the same zone.
Temperature and motion: Try your usual sheets, protector and blankets for several nights. A cool-touch surface is a brief sensation; sustained comfort depends on the entire sleep environment. If you share the bed, alternate lying still and changing positions, then test sitting and lying near the perimeter. These checks answer practical questions without treating marketing claims as measurements.
Decision window: For eligible direct orders, the product FAQ describes a 365-night trial starting on receipt, with 30 days before a return request. It also says the comfort trial can be used once and clearance purchases are excluded from returns or exchanges. Keep the mattress clean and review the applicable terms and any charges with your seller; another retailer’s policy may be different.
Is the Upgrade Worth Paying For?
The LX Elite adds a separate lumbar foam layer and a taller profile to the LX’s latex-and-foam hybrid concept. That may matter if you specifically want that construction, but neither the extra thickness nor a larger layer count proves better pressure relief or durability. Compare the same size and firmness, including shipping, return charges and any sheets or frame changes you would need.
If a cooler bedroom is your chief goal, consider bedding and room conditions alongside the mattress. If you mainly want customizable firmness, compare the three choices and the trial or exchange rules first. Yawnder has not tested the LX Elite or LX, so the comparison is based on the brands’ published descriptions rather than a measured winner.
Frequently Asked Questions
Is the LX Elite entirely latex?
No. It combines a Talalay latex layer with several foam layers and a coil support system.
How tall is the LX Elite?
Brooklyn Bedding’s comparison card on the LX page lists the Elite at 15.5 inches. Confirm the current specification and measure your frame, doorway clearance and fitted sheet pockets before ordering.
Does it use active cooling?
No powered cooling system is described. Its cover and foam are passive cooling features.
Is the LX Elite better than the LX?
It offers a different construction and taller profile, but the better choice depends on your body, preferred firmness and the current price difference. Try both if possible.
Our Final Take
The LX Elite gives shoppers three firmness choices and a combination of latex, foam and zoned support. Compare it with the LX in the same size, then test your chosen feel and review the direct seller’s current trial conditions.
