Why choose a Sealy mattress?

Great sleep starts with the correct support. For unparalleled construction, unique engineering for your body and the guarantee of a great night’s sleep, Sealy have the mattress for you. Choose between the innovative PostureLux or Posturepedic range for the ultimate in tailored support, to give you the comfort you need for that much-needed time to unwind in bed. Sealy is proud to be the start and end of people’s daily routines and goes above and beyond in terms of research and innovation.

Sealy Posturepedic technology™

Elevate Ultra mattresses offer deep-down support with their twice-tempered AlignSupport® Coil and structure with a UniCased® system. Expect a firm wall around the entire edge of the mattress that creates long-lasting durability, extends the sleep surface, and prevents the roll-off feeling. They also feature:

ProShield® technology

Sealy ProShield® technology is endorsed by Allergy UK as it helps keep your mattress clean and keeps allergens at bay.

SmarTex® fabric

SmarTex® fabric wicks away moisture whilst you sleep, keeping you cool and regulating the temperature of your sleeping environment.

MemorySense® ComfortCore™

The MemorySense® ComfortCore™ is positioned in the mattress's centre third for added pressure relief for the most vulnerable parts of your body. It mainly focuses on the heaviest parts of your body, such as your hips and lower back so rest assured you'll get the support and comfort you need.

Sealy PostureLux Collection

Every PostureLux mattress features bespoke PostureTech Core Support Plus™ springs, twice tempered with six turns for increased height and support. Like the Posturepedic range, you can enjoy a fully encompassed edge, with the added benefit of reinforcement from UniKey®. They also feature:

ProShield® technology

Sealy ProShield® technology is endorsed by Allergy UK as it helps keep your mattress clean and keeps allergens at bay.

SilverFresh™ technology

SilverFresh™ technology is expertly woven through the fabric of every PostureLux mattress. Designed to keep your sleep surface fresh, this innovative technology prevents bacteria to promote sleep health.

Latex Comfort Layer

Paired with supportive pocket springs is a Latex comfort layer, responding to your body’s shape and motion to give pressure relief targeted to the areas that need it most. Plus, latex is naturally anti-bacterial, designed to keep your mattress feeling ultra-fresh throughout its lifespan.

Which Sealy mattress is best?

Your best Sealy mattress depends on personal preferences such as what fillings you like and how you sleep. Naturally, different positions require different levels of support. Rest assured, there’s a Sealy mattress for just about everyone. The full range includes four comfort grades:

• Plush medium comfort: PostureLux Forbes
• Medium comfort: Elevate Ultra Antuco & PostureLux Kindra
• Firm comfort: Elevate Ultra Daito & PostureLux Wilton
• Very firm comfort: Elevate Hagen

Which Sealy mattress is best for back pain?

The Sealy range is a great choice if you experience back pain when sleeping.

Elevate Ultra Posturepedic mattresses have been specially designed with technology that provides excellent support by distributing your body weight. When you're in a deep slumber they alleviate stress on your spine, relieve painful pressure points and aid the spine's natural alignment.

For precise support that’s uniquely engineered to your shape and motion, the PostureLux collection has the solution for you. The PostureTech Core Support Plus™ springs are engineered to reduce lateral movement and provide responsive support as you sleep, with an added layer of latex for targeted pressure relief.

Which Sealy mattress is best for side sleepers?

If you tend to sleep on your side (more than half of British adults do), we recommend you opt for a soft to medium comfort grade. This helps cushion vulnerable pressure points and ensures you’re adequately supported. The PostureLux Forbes mattress offers that perfect halfway point, with a plush medium comfort grade to give cosy support. For a true medium feel, check out the Elevate Ultra Antuco mattress, complete with a luxurious pillow top for extra cushioning.

Which Sealy mattress is best for back sleepers?

If you tend to sleep on your back, we recommend you opt for a Sealy mattress with a firm comfort grade. This helps your back remain neutrally aligned and it will prevent your body from sinking too far into the mattress’s surface. If that sounds like your cup of tea, the Elevate Ultra Daito mattress has a firm comfort grade for optimal support, moulding quickly to your sleeping position. For responsive support, the PostureLux Wilton mattress comes complete with a firm latex layer for pressure relief and lumbar support.

Which Sealy mattress is best for front sleepers?

We recommend front sleepers choose a medium to firm mattress to ensure their stomach is supported and prevent their back from arching. Choose either the Elevate Ultra Antuco or PostureLux Kindra mattress if you’re a stomach sleeper. With a medium comfort grade, these luxurious choices provide just the right blend of softness and firmness, plus reactive support.

What Sealy mattress sizes are available?

Our Sealy mattress range features sizes single, small double, double, king, and super king. There is a size to suit all bed frames. You can even choose a Sleepmotion compatible version. It's tailored to fit our range of Sleepmotion adjustable bed frames. For more information on dimensions, please visit our bed and mattress size guide.
