Whether you’re an early riser or a night owl, the Holst mattress is designed to support you unconditionally. To provide the best support, your mattress should allow your spine to maintain its neutral posture whilst you sleep, reducing muscular tension and strain. Backed by scientific research, Sealy Posturepedic technology works to provide correct support by aligning the body position during rest. It begins with the AlignSupport TM coil, a unique two-stage spring system that has been expertly designed and tested right here at Sealy. Its unique geometry senses your body as it meets the mattress, providing the initial response. Followed by deep down support that sits at the very heart of the coil to evenly distribute your body’s weight. It’s twice tempered too, providing dependable performance, year after year. Each and every Sealy Posturepedic is UniCased. The proprietary keys lock into place for the ultimate stability, bringing structure to every point around your mattress, allowing you to benefit from a larger usable sleep surface. It also removes the rolling-off feeling when you are snoozing or getting ready for the day ahead. Sturdy and supportive, UniCased acts as the perfect seating edge for putting your shoes and socks on. That’s not all, BasePlank pulls everything together perfectly. A stable foundation that you can trust, it underpins the AlignSupport TM system and UniCased edge support throughout the lifespan of the mattress. The ComfortCore is placed in the centre third of the mattress to target your hips and lower back for ultimate pressure relief. A combination of medium softness and firm foams provides a medium feel that is not too firm not too soft, a perfect in-between. Followed by our very own InfiniLux - a luxe, premium foam that is resilient and designed to provide long-lasting comfort you can depend on. The Holst mattress doesn’t just feel great, it looks great too. Each textile has been developed and designed to the highest quality to add a hint of luxury to your sleep space. Not only that, it’s bursting with technology for a more restful night’s sleep. SmarTex disperses heat away from the skin and regulates your temperature as you sleep.
