Excellent Matches For Rubix

  • Folks seeking a customized bed – The Rubix bed saves you the concern of selecting a firmness when you purchase because the comfort foams can be adjusted at home to suit your changing needs. Soft one day but firm the next; it’s all up to you.

  • Hybrid fans – A combination of foam and springs can provide the advantages of both materials, such as the comfort and body conformance of foam with the airflow and bounce of coils.

  • Hot sleepers – The breathable cover and airflow through the individually pocketed springs in this mattress should help you keep the bed temperature neutral while you sleep and ensure you don’t wake up sweaty.

Possible Rubix Considerations:

  • It won’t provide a slow sink – This mattress contains Energex™ foam that is more responsive than traditional memory foam. While some folks may love this, others who enjoy a slow sink into their bed may prefer a different model.

  • It won’t have an all-foam feel – A hybrid mattress is a fusion of foam and coil systems. That being said, some shoppers prefer an all-foam bed and may need time to get used to the feel of coils. The good news is you have up to 120 nights under the trial period to decide whether this hybrid bed is for you.

Construction: What’s Inside the Rubix?

The cover of the Rubix is a 1.5-inch quilted Eurotop. This cover is designed to promote airflow, so you don’t overheat during the night. The cover also has a zipper to allow you to customize the comfort layers of the bed.

In total, this bed comes with 14.5 inches of materials, but since only two of the three comfort layers can fit at a time, it will stand at 12.5 inches when in use.

  • Below the cover are two 2-inch layers of Energex™ Foam. When you purchase a Rubix, the bed comes with three 2-inch Energex™ Foam layers, but as mentioned, only two of them can fit inside the Eurotop cover at a time. Each foam layer has a different level of firmness, including soft, medium, and firm. This allows you to customize your Rubix mattress to your preferred feel. Energex™ is designed to provide the pressure-relief of memory foam with the responsiveness of latex.
  • The next layer is a 2-inch transitional foam that should help ease you into the coils further below.
  • The innerspring unit is made up of 1,024 individually encased Ascension® coils and stands 6 inches thick. This layer serves as the primary support mechanism of the Rubix and should help deliver motion isolation as well.
  • The base of this mattress is a 1-inch high-density foam. This layer gives the bed durability and reinforces the Ascension® coils as they compress.

First Impression: How Does It Feel?

The Rubix is compressed and shipped in a box to your home. The company recommends waiting 3-5 hours for the mattress to expand before lying on it.

When you lie down, you’ll feel the soft comfort of the Eurotop’s quilted cover combined with Energex™ foam that holds your body in a gentle hug. The responsive foams should not cling to your shape or make you feel stuck, but since the bounce is deeper, rolling over might be an issue for those who struggle with mobility.

Pressure Relief

As you lie down, your weight will begin to put pressure on some parts of the body. Unfortunately, these areas can become sensitive to pressure and may cause discomfort or pain. These pressure points, as they’re referred to, can help find relief through a well-made mattress that incorporates pressure relieving features.

The advantage of the Rubix is that you can layer the Energex™ foams in accordance with the amount of pressure relief you need to rest comfortably. For example, those who want something more plush may only layer in the soft foam or use a combination of the medium and soft foams. While this foam doesn’t have the highly popular memory materials, Energex™ is designed to give sleepers the same cradle-like feel that you would experience with memory foam. Additionally, the plush Eurotop should further soften the bed to ease any achy joints and muscles.


A supportive mattress is also important because it helps keep your spine in proper alignment. When the spine becomes maligned, this can lead to problems with back or neck pain.

The Rubix’s support system is comprised of an innerspring unit with 6-inch individually encased Ascension® coils. The advantage of pocketed coils is that they react independently, allowing them to contour to your body to provide the necessary support where you need it most.

In addition to these coils, the bottom of the Rubix contains a 1-inch highly-dense foam base. This base aids in bed support by reinforcing the coils as they compress while providing a durable foundation.

Preference-based Features

Multiple Firmness Options

This bed comes with three 2-inch layers of Energex™ foam, including a soft, medium, and firm option. With the removable Eurotop cover, you can arrange these foams to create your ideal firmness.


This mattress features a zippered Eurotop cover that’s designed to foster airflow and keep the bed cool.


In addition to a breathable Eurotop, this bed features coils further below, which should deliver even more airflow.

Exceptional Edge Support

Mattresses designed to compress into smaller boxes show some slight changes in support on the far edges, and this hybrid performs as we expect from this industry. You are free to lie down on the side of the bed as you normally would without feeling any significant change to the support system, but you might notice some compression when seated on the very edge with all of your weight concentrated on one spot.

Motion Isolation

The foams in this mattress, though responsive, do a great job of capturing vibration at its source and preventing most of it from moving across the bed and the pocketed coil unit also cuts down on motion transfer. You may feel a slight bit of disturbance when your partner gets in and out of bed, but this choice performs excellently for a hybrid and should not rattle you awake.

Adjustable Base Compatible

The Rubix is compatible with an adjustable base.​

Handcrafted in the USA


Eco-Friendly Certifications

The foams in this bed are CertiPUR-US® Certified, which indicates they do not contain dangerous levels of certain chemicals and heavy metals such as mercury and formaldehyde.

Overall Summary

Brooklyn Bedding’s answer to the demand for customization has yielded Rubix, a versatile hybrid that you can adjust at home to create the comfortable feel you dream of paired with the firm support of coils.

Side Sleeping Icon

Side Sleepers


Most side sleepers should feel comfortable lying on their side, but they should be mindful of excess pressure that can build up under the hips and shoulders in this position. If you tend to feel extra pressure in this area, the softer configuration may suit your needs better.

Back Sleeping Icon

Back Sleepers


Most back sleepers should like how the layers of foam conform to their shape and create a well-supported and low-pressure sleeping environment. Tastes in this category do tend to vary, and some exclusive back sleepers may prefer the firmer setting.

Stomach Sleeping Icon

Stomach Sleepers


Stomach sleepers often are best suited by firmer mattresses so that their heavier midsections do not sink too low and affect good spine alignment. Occasional tummy sleepers or those who are lighter than average might prefer the Medium, but many may gravitate towards the Firm.

Combination Sleeping Icon

Combination Sleepers


A medium-firm setting adapts well to different positions, which is a particular advantage to combination sleepers who do not commit to one sleep style. The easy customization of the Rubix is a strong advantage for combination sleepers, making this an excellent choice for these consumers.

Couples Icon



The bed’s multiple firmness options allow you and your partner to create a bed that caters to both of you. Another benefit of the Rubix is that it should do well when it comes to motion isolation. This is important for couples concerned about waking their partner if they move during the night.

Heavy Sleepers Icon

Heavy Sleepers


Individuals who weigh substantially more typically prefer a firmer bed to support them well. Some heavier folks may enjoy the Firm setting on the Rubix. However, those who weigh over 300 pounds should consider the company’s Titan mattress, which is specially designed for larger frames.

Light Weight Sleepers

Light-Weight Sleepers


Lightweight sleepers, who usually go for plush beds, will appreciate the Eurotop and likely gravitate towards the softer setting, especially if they weigh under 120 pounds. However, lightweight stomach or back sleepers may decide to incorporate the medium foam for something a bit more supportive.

Overall Value


The company includes three layers of Energex™ foam, and once you decide on your preferred feel, you can select two layers to place within the Eurotop.

Should your needs change, you can adjust the feel by swapping out layers or changing their arrangements, allowing you to experience the joy of a brand new bed without making another purchase.
