Founded in 1995, Brooklyn Bedding has been around a lot longer than most mattress start-ups. Since they rebranded as an online mattress company in 2008, this industry leader has built a reputation out of designing and manufacturing their own high-tech mattresses in the U.S., which keeps prices lower than other luxury mattress companies. Currently, their line-up consists of nine mattresses that include latex, foam, and hybrid choices.

This review will focus on the Rubix, one of its five high-tech foam hybrids. The Rubix sets itself apart with its customizable firmness: each mattress comes with three foam layers at different firmness levels that can be combined to suit different types of sleepers. Because this layer is made of Energex foam, a latex alternative, it possesses all the contouring and pressure point-relief of foam with the cooling and bounce of latex. Meanwhile, a 6-inch core of pocket coil springs ensures more support than most all-foam and latex mattresses, without compromising on motion isolation.

In this review, we’ll break down the specs of this innovative hybrid, before analyzing its performance and going over the sleepers most suited to its features.

Rubix Mattress Sizing and Pricing

The Rubix mattress is available in all of the regular sizes, with prices beginning at $899 for a Twin. Brooklyn Bedding does not provide dimensions for the Rubix mattress.

Twin XL38” x 80”10″60 lbs$949

The firmness level of a mattress can be ranked on a scale of 1-10, with 1 being very soft and 10 being very firm. This will feel different from sleeper to sleeper, but in general, all mattresses will fall in one of three categories: soft (1-3), medium (4-6), or firm (7-10).

The Rubix mattress comes with three removable and interchangeable Energex foam layers, two of which can be combined and put in the Euro top at all times. It comes in soft (3.5), medium (6), and firm (7.5), which means all sleepers, regardless of position, should be able to find a combination of firmness level that works for them.


Brooklyn Bedding will ship the Rubix mattress anywhere in the United States and to most places in Canada. You can buy the mattress on Amazon, and if you’re in Arizona or Utah, you can also try it out at one of the brand’s showrooms. Brooklyn Bedding mattresses are also available from the brand’s partners, including two Sleep Sherpas in Chicago, IL and Edina, MN, Bobcat Mattress in Bozeman, MT, and SleePare in New York, NY.

Rubix Mattress Inside Cutaway

The Rubix is a hybrid foam mattress that consists of five layers totaling 14 inches. At the top sits a 1.5-inch comfort layer made out of quilted foam, which keeps the air flowing to avoid the heat-retention found in typical memory foam. Underneath is another 4 inches of Energex foam, combined from two out of three interchangeable 2-inch layers. These come in soft, medium, and firm, so the bed can be customized to suit a variety of different sleepers. After the Energex comes a 2-inch transition layer, which acts as a cushion before the 6-inch innerspring core layer. Built from 1,024 individually wrapped coils, it provides support and motion isolation, and is reinforced by 1-inch of high-density base foam.


Brooklyn Bedding ships free to all locations in the contiguous U.S., with shipping to Alaska and Hawaii starting at $125 per mattress and shipping to Canada starting at $250 per mattress. In the lower 48 states, Brooklyn Bedding ships via FedEx Ground, which takes 3 to 5 business days after an initial processing period of 1-3 business days. In Canada, the shipping company is UPS. Brooklyn Bedding ships their mattresses wrapped in plastic and compressed in a box. No assembly is required beyond normal unpackaging and decompression.

Brooklyn Bedding’s 10-year-warranty for its mattresses begins on the day of purchases and covers a list of defects outlined on their website. The brand will repair or replace all qualifying defects at their discretion.

Rubix Mattress Performance

Motion Isolation

Motion isolation refers to a mattress’s ability to keep you from feeling your partner’s movements when they shift their positions or get up throughout the night. This depends on a mattress’ level of cushioning and contouring. In general, foam mattresses, which hug the body closely with their high-density cushioning, isolate movement the best, while less responsive mattresses like those made of innersprings have more motion transfer.

Despite being a hybrid, the Rubix’s two different materials actually both contribute to its superior motion isolation. Its topmost foam layers hug individual sleepers and keep their movements to their sides of the bed, while working with the layer of individually wrapped coils to further limit motion transfer.

Edge Support

Traditionally, all-foam and all-latex mattresses aren’t supportive enough around the perimeter, which makes them sink or sag under your weight when you sit on the edge or get out of bed. Because the Rubix has a layer of individually wrapped coils, it offers more edge support than foam and latex mattresses.

Heat Retention

Traditionally, foam mattresses have trapped heat the most, making latex and innerspring mattresses your best bet for a cooler night’s sleep. In recent years, however, enhanced and alternative foams, as well as infusions of gel and copper, have largely fixed this problem.

Because the Rubix’s foam is made out of Energex, it doesn’t sleep hot. Energex is a latex alternative, so it’s just as cooling as latex. Additionally, the Rubix is covered by a 1.5-inch quilted top that doesn’t trap heat and promotes airflow.


Off-gassing refers to the smell a new mattress gives off when it’s first unpackaged. This smell is typically stronger with foam and latex mattresses, and can last anywhere from a few hours to a few days.

The Rubix’s smell will disappear within a few hours with good ventilation, making it superior to other foam and foam-incorporating hybrid mattresses when it comes to off-gassing.


Foam mattresses traditionally offer less support than other types of mattresses due to the high amount of sinkage. Because the Rubix is a hybrid, however, it avoids the pitfalls of foam mattresses. The more than 1,000 pocket coils that make up the 6-inch core keep the mattress exceptionally supported, especially around the edge, and the high-density base layer adds an extra layer of stability and reinforcement.


Foam and latex mattresses traditionally contour to the body quite well, and the Rubix is no exception. In fact, because the mattress’ second layer is made out of the latex alternative Energex, it combines the conforming abilities of both materials, while retaining latex’s bounce.


Quite a few aspects of the Rubix’s design work together to make it longer-lasting than a traditional foam mattress, which has a reputation for splitting or otherwise degrading too easily. The Rubix uses foam made from more durable materials: the latex alternative Energex and high-density foam. Not only do the three interchangeable Energex layers allow each foam to last longer, but the foam base also reinforces the mattress’s stability and durability.


The best mattresses for having sex are those that have a lot of bounce, such as those made out of latex. Traditionally, foam mattresses are not as suitable for sexual activity, because they tend to contour to the body (latex both conforms and bounces).

However, the Rubix’s second-most foam layer is made out of Energex foam, which has as much resilience and bounce as latex. Enhanced with the innerspring layers in its core, this makes the Rubix an excellent choice for sex.


In general, all-foam and all-latex mattresses are less noisy than innerspring mattresses, which can make quite a bit of noise when sleepers move around. Like many hybrids, the Rubix falls somewhere in between. Because its innerspring layer is placed between three top foam layers and a high-density base layer, it will be far less noisy than an innerspring mattress, although still not as quiet as a mattress made entirely of foam or latex.

What Type of Sleeper Is Well Suited to a Rubix Mattress?

Side Sleepers: The Rubix’s customizable firmness levels means all sleepers should be able to find a combination that works for them, regardless of sleeping position. Because side sleepers need mattresses that are soft and responsive but still supportive, combining the soft and medium Energex foam layers should work the best for side sleepers. Sleepers above 230 lbs may find this combination too soft for their needs, so a medium-firm or soft-firm combination may work better.

Back Sleepers: For optimal spinal alignment and support, back sleepers (especially those who weigh over 230 lbs) generally work the best with mattresses that are on the firmer end of the medium category. Therefore, we’d recommend a medium-firm combination, although sleepers should experiment until they find one that works the best for them.

Stomach Sleepers: Firmer mattresses are the best choice for stomach sleepers, for whom too much sinkage will lead to difficulty breathing. The Energex’s bounce will prevent this issue, and we’d recommend a firm-medium combination for most stomach sleepers. As with side and back sleepers, those above 230 lbs may find this mattress too soft for their needs.

Our Verdict

The Rubix is an excellent choice for sleepers who want a versatile, crowd-pleasing mattress they can further tailor to their tastes. Its biggest selling point, the interchangeable Energex foam layers, allows most sleepers to find a combination that accommodates their sleeping positions and firmness needs. Like the other high-tech hybrids in the Brooklyn Bedding line-up, it also combines the best parts of foam, latex, and innerspring mattresses while eliminating these materials’ individual shortcomings.

The only drawback with the Rubix is its warranty policy. At 10 years, it’s definitely one of the shortest warranties out there, especially considering the lifetime warranties now offered by many newer start-ups.

Still, Brooklyn Bedding has the reputation and experience to back up the quality and performance of their mattresses. Ultimately, if you’re looking for a customizable high-tech hybrid but want to stick with a reputable mattress veteran, then the Rubix is an excellent choice.
