Frequently Asked Questions

Answers to some of the frequently asked questions are customers have about the Back Science™ Bed and the technological innovations we utilize. Have a question not on this page? Feel free to send us an email to or give us a call at (800) 667-1969 to speak with a sleep expert who can personally assist you in finding the perfect fit and answer any questions you have about our products and services.

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.

5 out of five star rating on Trustpilot

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!

5 out of five star rating on Trustpilot

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!
