SonoFlex is a dedicated mattress manufacturer committed to making advanced, back-care mattresses accessible to all.

Back-care mattresses—which are also referred to as spinal mattresses—are designed to provide exceptional support for the spine. They help to align your posture during sleep, reducing pressure points and potentially alleviating back pain. The reason these mattresses are usually more expensive than ordinary ones is that they incorporate superior-quality materials rather than substandard elements like rebond foam or recycled shred.

Prominent brands such as King Koil, Slumberland, Four Star, Serta, and Simmons, however, elevate their prices due to brand marketing, ambassador endorsements, and dealership costs.

At SonoFlex, we strategically utilize the same high-end materials – from the spring system, transition layer, comfort layer, to the covering fabric – but minimize costs by avoiding expensive brand ambassadors and relying on the power of word-of-mouth marketing.

Let us introduce you to our series:

SPINE 1: A 12-inch mattress crafted with heat-tempered Bonnell coils and crowned with our proprietary Spinal Foam.

SPINE 2: An advancement on SPINE 1, featuring foam encasement for added stability, enabling you to safely sit or sleep at the edge of the mattress.

SPINE 3: Our ultimate offering. A luxurious 13-inch mattress equipped with thick pocketed coils and enhanced with a layer of our exclusive Spinal Foam and Comfort Soft Foam, ensuring a restful and cozy sleep.

Our SonoFlex Spinal Foam has been rigorously tested by SGS and confirmed to be completely free of toxic chemicals. Furthermore, it undergoes rigorous LGA testing to verify its durability, ensuring it will last up to 10 years – a promise we back up with a 10-YEAR WARRANTY.

Our mattresses are ideal for those experiencing back pain and require a medium-firm mattress to realign their posture and spine effectively.
