Pushing the Boundaries of Sleep Technology

Lumbar-Flex™

Zoned Lumbar Support Reinforcement

Our proprietary Lumbar-Flex™ Zoned Lumbar Support technology strengthens and reinforces the horizontal midsection of your mattress to keep your lumbar supported and prevent sinking in. Mattresses that are unsupportive due to excess softness in the middle or cheap materials that mat down cause your hips to sink and put your spine out of alignment. With reinforced lumbar support, the Back Science™ mattresses promote proper spinal alignment by keeping your hips and lumbar supported to ensure your spine stays straight throughout the night. Everyone's body is different and you may need a different level of lumbar support than someone else, so we have made the lumbar support in the mattress easily adjustable by simply unzipping the mattress and sliding in and out the lumbar support zone foam to achieve the right amount of lift for you, personally.

PostureFlex™

Hypergel Buoyant Lift Surface

Introducing the PostureFlex™ Hypergel-Infused Comfort Surface. This one-of-a-kind technology uses a gel-infusion to give you extra buoyant lifting support right where you need it. Many mattresses are either too soft and lack support or too firm and can't contour to the bumps and curves of your body. Our Hypergel surface adapts instantly to the bumps and curves of your body to give you instant pressure-point relief. Our PostureFlex™ gel infusion provides an adaptive, conforming surface that matches your body like memory foam, however, unlike memory foam our hypergel has a buoyant, "springy" lift that help to come up to meet you, filling in the gaps in support and preventing you from sinking into the mattress too far. With the newer "gel-type" mattresses you get the benefits of latex and memory foam without the pitfalls!

BackFlex™

Adjustable Back & Lumbar Support Bases

Similar to the lumbar adjustment you may have in your car, select BackFlex™ adjustable base models come equipped with fully adjustable back support so you can control your overall back support on the fly. Depending on how far down the mattress you lay (from head to foot of mattress), you can control whether you add in extra lumbar support or more overall back support. On days when your back is extra sore, recovering from an injury, or otherwise needs more support than you normally do, you can use select adjustable base models to bring in extra support through the mattress that adjusts with the press of a button. In addition to the basic adjustable base features that allow you to raise and lower the head & feet section of the mattress, the adjustable lumbar / back support allows you to fine-tune your comfortable resting support level on the fly.

ResiliFlex™

Strengthening Lumbar & Edge Support

At the core of the Back Science™ mattress is the ResiliFlex™ strengthening support transition layers, which serve to add extra conforming support to the mattress and prevent you from sinking in, as well as reinforce the zoned lumbar support and edge support in the mattress. Using our ResiliFlex™ high-density support foam, we create a strengthened barrier around the edge of the mattress to prevent you from feeling "pushed off" the edge of the mattress. With the exception of the Series 1 mattress, which uses ResiliFlex™ support foam to add extra strength to the lumbar portion with zoning, our mattress models use high-quality, individually-wrapped spring coils to reinforce the buoyancy and support of the mattress. Our wrapped coils, with over 1,000 in a king size, are zoned to bolster the edge zoning and reinforce it even further to take your edge and lumbar support to the next level.

GripLock™

Modular Cover System

Traditional mattresses using wool, cotton, or other fiber top-layering need to sew or tuft the inside layers of the mattress into the cover to keep everything in place, similar to how a down "puffer" jacket works. However, due to the nature of our PostureFlex™ gel-infused layering, we have designed a modular cover system that can be unzipped and opened on the fly for easy access to make adjustments or customizations to the feel and support, while keeping everything locked in place tight with our GripLock™ stretch technology. Our stretch cover technology not only allows for easy modifications, but also bolsters the buoyant support and plush comfort of the Back Science™ bed by pulling in at the sides and creating a loaded "spring" effect in the top layer, resulting in even greater support and an even more luxurious feel.

Airflow Transfer System™

Up to 100Xs More Breathable

Our *Patented Airflow Transfer System Cooling Technology is a system of using thousands of holes in the upper portion of the mattress that connect all the way through to horizontal channels lower down in the mattress to allow for up to 100Xs more breathability than other mattresses on the market. This technology works by allowing air to freely flow through many pathways in the top of the mattress and out the sides, and vice-versa. Creating these open pathways exponentially increases the breathability of the mattress, which does the work of carrying your body heat out throughout the night and keeping the total system's temperature down as a result. Continuously cycling new air throughout the mattress over the greatly increased surface area created by the airflow transfer system provides a breathability and cooling effect that cannot be achieved any other way.

At Back Science™, we prefer to allow the customer to customize and easily access the insides of their mattress in the unusual case that an adjustment or modification is needed, and wish to promote the spirit of transparency and honestly with our customer base.

Airflow Transfer System™

Up to 100Xs More Breathable

*Patented Airflow Transfer System™ Technology

Our *Patented Airflow Transfer System Cooling Technology is a system of using thousands of holes in the upper portion of the mattress that connect all the way through to horizontal channels lower down in the mattress to allow for up to 100Xs more breathability than other mattresses on the market. This technology works by allowing air to freely flow through many pathways in the top of the mattress and out the sides, and vice-versa. Creating these open pathways exponentially increases the breathability of the mattress, which does the work of carrying your body heat out throughout the night and keeping the total system's temperature down as a result. Continuously cycling new air throughout the mattress over the greatly increased surface area created by the airflow transfer system provides a breathability and cooling effect that cannot be achieved any other way.


Our head of product development, Chiropractor Dr. Rick Swartzburg, D.C. developed and patented this technology in 2006. Since then, many manufacturers in the industry have tried and failed to replicate this technology with various methods. Many mattresses on the market ventilate their layers by punching holes through them without channeling, which presses one end of the holes agains the flat layer below it and, much like a bunch of pipes sealed at one end, don't allow nearly as much, if any air to actually flow through them. Some mattresses simply groove or channel the sides of the bed which, not only don't allow for nearly the same level of airflow as connecting them to the top, don't actually ventilate the top layers which are storing the majority of your body heat.


While technologies such as PCM, or "active" cooling in mattresses has been a staple and somewhat effective technology used in mattresses in recent years, they provide a "cool to the touch" sensation when you first lay down, that does not tend to last throughout the whole night. While active cooling can play a helpful part in keeping your mattress cooler and help you fall asleep, without breathability, any mattress will still get hot as it absords the heat from your body. Ultimately, the combined natural cooling effect of the hypergel top layer of the Back Science™ bed paired with the Airflow Transfer System™ creates a much cooler sleeping experience over the other technologies on the market.

Update: After 2 months my wife's back pain at night is gone! Thank you Dr. Rick and the incredible team at Ultrabed for your recommendations and expertise in finding us a great Back Science mattress!

Back Science Review Image of Customer in Showroom

My wife and I just visited the Ultrabed showroom in Agoura Hills, CA. What a great experience! Dr. Rick (the owner) and Jordan (salesperson), were patient, helpful, and no-pressure. They listened to our concerns regarding my wife's back pain with our current mattress, and as a chiropractor Dr. Rick was able to recommend various brands of mattresses and explain their design attributes, heat conduction characteristics, and features. Ultimately we settled on a custom Back Science mattress which is Rick's patented and proprietary mattress. We are looking forward to taking delivery in a few weeks and getting more restful nights of sleep.

The showroom is conveniently located off the 101 freeway, with ample parking, gentle music, a water feature, soft lighting, and a clean aesthetic. It's obvious this company cares about their customer experience and stands by their products. Highly recommend!

I'm a stomach sleeper so finding a mattress that is both firm enough, but also cushioned enough for my hip and shoulder pressure points is always a challenge. The folks at Ultrabed in Agoura Hills, CA were amazing. They let me try out every firm mattress they had and explained the differences between them. I settled on the Back Science Series 2, it has the perfect combo of firmness and cushioning. The lumbar support is great and helps keep my hips elevated properly and the gel foam topper gives just the right about of cushion without feeling like I'm drowning (a relief after having achy hip pressure points every morning from my old mattress). The edge support and motion isolation are also great. The delivery and set-up was super easy and they even called to check-up on me after a few weeks of sleeping on the new mattress to see if everything was feeling good. The only thing this magical mattress couldn't do was convince my cat not to wake me up at 5 am.

I found our mattress by going to the local mattress store and trying it out. The salesperson listened to our needs, he was most helpful and knowledgeable, explaining which mattress we would most benefit from. We went with the Back Science Series 2 Mattress and the Adjustable Bed with Lumbar Back-Flex Technology.They offered a good return/exchange policy in place in case it did not work out. About 2 months later, I received a phone call to see how satisfied we were with the bed. I shared the bed is amazing, especially how the adjustable bed cradles you but I would have liked it to be a little firmer along the edge. They scheduled the mattress to be the same day, pick up/return, so to give it the firmer support we were looking for. We could not be happier with our Back Science Series 2 Mattress and the service was over the top!

Overall, the Back Science Bed tends to be on the firmer side, but it is also universally comfortable, thanks to the contouring proprietary extra buoyant ResiliFlex™ support base and Posture-Flex™ Gel Comfort layers™. You don't need a mattress to be as hard as a rock in order to support the spine properly. Back pain sufferers too often go to a mattress that borders on floor like firmness, thereby losing any ability to fill in the bumps and curves of the body, which will not only create pressure points over time, but lead to an imbalance of the spinal alignment. While we have spent years developing the right formulation for proper spine support, we do recognize that there are going to be some cases where the customer requires a different firmness and in those cases, which is why we use our proprietary modular cover system that allows us to make firmness changes, as well as adjust the amount of lumbar support right from your home. In those special cases, we will do a custom comfort layer exchange to ensure you get the right firmness changed out at no additional cost whatsoever! You can also rest well knowing that our 4-month sleep trial gives you the ability to even exchange your mattress model if so desired and we will cover all the shipping fees to do so. Of course, you can also take us up on our 4-month sleep trial and return the mattress, since our ultimate goal is to help you find the best solution for your back pain, regardless of what solution you need to make it happen!

While we have an over 90% success right from the get go, we realize that each person is unique and after 20-years of producing mattresses and shipping them world-wide, we have perfected a solution to address any issues that can come up, should a customer not be 100% satisfied for any reason whatsoever. First, if the firmness is not to you satisfaction, we offer our totally free modifications that are easily performed in your own home. Thanks to our proprietary GripLock™ modular cover system, you can easily adjust the overall firmness of your mattress, as well as adjust the amount of lumbar support with a simple zip-on and zip-off alteration of the layering. In some cases, we may need to exchange the layering for a different level of firmness, but those layers can easily be sent through a simple UPS shipment and again, there are no extra fees associated with any modification you need during your worry-free 365-Night Sleep Trial. We can even exchange the mattress or customize a whole new one at no cost, should that be necessary for any reason. We want to establish a life-long relationship with you as a valued customer and just like we have done with our customers over these last 20-years, we offer our free modification and exchange policy to ensure that you have that certainty that we will take care of any needs you have and when we cannot do that for any reason, you can also rest assured that you can take us up on our 4-month sleep trial and even return the mattress if needed.

Thanks to our Modular Cover System, you can easily alter the firmness on one side of the mattress right from your home. If you are sure from the start that it is something that may be needed, you can easily select which firmness you want for each side from the product page and our sleep experts are here to assist you with any customizations / modification you would like to make in your mattress before it even ships to you. Just give us a call at (800) 667-1969 and we'll be happy to help!

Our customers who pair their mattress with an adjustable base often find they want separate adjustability on one side vs the other so they can, for example, stay up and watch TV or read while their partner lays flat to go to sleep. In this case, a split mattress design allows you to do this by having 2 separate mattress halves that can each move independently. However, many of our customers want to still be on one connected mattress with their partner, or don't like the idea of a seam in the middle of the mattress, this is where the Split-Top® design comes to the rescue. By only splitting the head portion of the mattress and leaving the foot portion connected, you can separately adjust the head of each side from one another without feeling separated or worrying about the mattress sides moving apart from each other. The Split-Top design does limit the amount of separate foot adjustability from one side vs the other, however most of our customers find that you can still get quite a bit of separate adjustability in the foot section without disturbing your partner's side, with just a slight slant in the middle while you've got the feet up on one side. Still confused about which design to go with? Call (800) 667-1969 to speak with a sleep expert who can help you make the right choice for you.

The important points to consider in determining whether a mattress will hold up over a long period of time are the following:

The quality of the foam
Back Science™ uses only the highest quality, 100% U.S.A. manufactured foam. Many companies will say their mattresses are manufactured in the US, but they actually use cheap foam that comes from overseas places like China and are merely assembled in the US. The material quality and quality control standards of these cheaper foams used in many mattresses on the market today not only dramatically hurts the longevity of a mattress, but can also create increased VOC emissions (toxic off-gassing). Many mattress foams that are not properly tested for VOC emissions can contain harmful, and even carcinogenic chemicals such as formaldehyde that are released from the mattresses into the air you breathe. Back Science mattresses are made with foam that is Greenguard® Gold certified, which is the highest standard of testing for VOC emissions, rated for schools and children.

The effect of sweat and skin oils on any soft surface
Because the Back Science Bed uses our Patented Airflow Transfer System™ to keep you from heating up in the night and the Posture-Flex™ Gel-Infused Surface has a cooling effect, less perspiration will occur and prevent damage to the mattress over time. It is still a good idea to use one of our Organic Cotton Kool-Flow™ Mattress Protectors to offer an extra layer of protection for your mattress from perspiration that breaks down foam, however, you can rest easy knowing that the quality materials and construction of your Back Science™ mattress are rated to last for 30 Years so, even if you don't have your mattress for its full life-span, you know it's going to support you better and for longer than other mattresses on the market today.

The foundation you use to support your mattress
While cheap box-springs are readily available, they do not offer a supportive surface for your mattress. The thinner construction of these less-supportive foundations allow them to "hammock" or "bow" in the middle which can not only put your spine out of alignment and cause restless or painful sleep, but can also damage your mattress long-term due to the foam sinking in-between the supports or misshaping from a foundation which does not stay flat. The best way to support your mattress is with one solid surface that is constructed not to bow under the weight of a mattress and person on top of it. Our True Platform Foundation is constructed right in our Southern California manufacturing facility with 100% USA materials with an array of sturdy support to keep the solid surface in shape and make sure “hammocking” doesn't occur. Our platform foundation is made similarly to hard-wood flooring with 2-3 times the amount of material normally used in a cheap box-spring to ensure lasting, quality support for the life of your mattress. If you choose to pair your mattress with an adjustable base, the steel supports and upholstered solid wood surfaces provide best-in-class support so you never have to worry about your base affecting your quality of sleep.

Due to the quality of the materials in our mattresses, they are not able to be shipped compressed like a bed-in-a-box, so they are sent large freight via special carrier in a full-sized mattress box, and the same for the adjustable bases. Smaller items such as pillows are usually sent via ups if ordered alone and arrive within a few days. Larger items such as mattresses and bed foundations usually arrive about 4 days to a week after they are shipped out from our facility, however, freight shipping times are just an estimate and cannot be guaranteed due to factors beyond our control such as changing weather conditions along the trucks' route.

We offer our industry-leading 365-Night Sleep Trial, during which you have the option for completely free customizations, exchange, or a full return with no restocking fees, ever. If you are unsatisfied for any reason with your mattress, just give us a call and we can not only exchange for another model, but also customize the mattress to fit you personally and make sure you end up with the right fit, and we offer this service at no additional cost whatsoever. If you feel that the Back Science™ Bed is not for you, you can return it for a full refund less shipping costs. We do not charge restocking or processing fees of any kind.

For full details on our Risk-Free 365-Night Sleep Trial, view full policy.

Our Back Science™ Mattresses are backed by our industry-leading 30-Year Limited Warranty which offers double the coverage and strength of most mattress warranties. The warranty is in place to cover you against dips / sag in your mattress occurring over time. Most mattress warranties will not cover you until you have a dip of at least 1.5 inches, however, our warranty covers you at only 3/4 inch for twice the protection. Getting a dip in your mattress is the quickest way to put your alignment off and cause aches and pains in your sleep. Even though the quality of the Back Science mattresses stands above the competition by holding up better over time, you can rest assured under the protection of our warranty that you'll have quality sleep for decades to come.
