Chiropractor Dr. Rick Swartzburg, D.C. gives demonstration of key features of Back Science™ Sleep System

Introducing the Back Science™ Sleep System

While I created the Back Science Sleep System to help back pain sufferers and those who want to maintain a healthy spine, it really was created by all the thousands of customers I worked with over the years who contributed their feedback about what did and did not work for them, including the bed support, comfort, temperature changes, partner motion transfer, edge support, ability to turn more easily on the mattress and even the finer details. It’s why I am so proud of the feedback I see day in and day out with Back Science and I look forward to one day hearing your experience added to those many voices!

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!
