Description & Features

Dive into a world of unparalleled comfort and innovative design with the Sealy Blackwood Elevate Posturepedic Mattress paired with our Premium Divan Bed. This unique divan set embodies the perfect blend of form and function, crafted for those who prefer the firmer feel of a truly supportive sleep.

Firm support with ComfortCore technology

The Sealy Blackwood Elevate Posturepedic Mattress is not your ordinary bed. Designed to ensure a restful night's sleep, this mattress boasts the patented AlignSupport® coil technology, an expertly engineered spring system unique to Sealy. The coil's geometry contours to your body as you sink into the mattress, offering balanced support and pressure relief.

This mattress goes beyond just comfort. It features the ComfortCore™, strategically placed in the centre to target your hips and lower back, offering essential pressure relief. Surrounding the ComfortCore are layers of Firm and Extra Firm foams, ideal for those who favour a firmer feel.

Designed to last, the UniCased® edge encases the mattress, allowing for a larger usable sleep surface and preventing any "rolling off" feeling. Alongside this, the BasePlank technology ensures structure and breathability, providing a solid foundation. Furthermore, ProShield® technology protects against allergens, keeping your mattress fresh throughout its lifespan, a feature endorsed by Allergy UK.

Platform top divan base enhances orthopaedic features

But it's not just about the mattress. The Sealy Blackwood Posturepedic Mattress finds its perfect partner in our Premium Divan Bed. Handmade in Yorkshire using traditional techniques and quality timber, this divan offers durability and firmness. With a solid platform top, it provides the ideal foundation for the mattress, ensuring an unmatched sleeping experience.

The Premium Divan Bed shines not just in comfort, but also in style. Available in a range of luxurious fabrics like Charcoal and Plush Teal it can be personalised to complement your bedroom décor. Its practicality is amplified with various under-bed storage options. Whether you need two drawers or an ottoman lift option, the divan offers ample storage space.

With chrome-effect glide feet, the divan is not just durable but easily movable, handy for those bedroom makeovers or under-bed cleaning. And remember, all this comes pre assembled, saving you the hassle of setup.

With the Sealy Blackwood Elevate Posturepedic Mattress & Premium Divan Set, you are investing in a world of superior comfort, innovative design, and unmatched durability.

While this divan does not come with one, it is perfectly designed to fit all of our headboards. Whether you prefer an elegant, buttoned design, or a simple, contemporary aesthetic, we'll have the ideal headboard to suit your style. You can also customise any of our headboards to match your chosen divan upholstery, creating the perfect divan set.

The gorgeous upholstery of this divan bed is made up of 88% polyester and 12% nylon, with a brushed fabric weave to ensure the softest feel possible.

What's included

Sealy Blackwood Elevate Posturepedic Mattress

Premium Divan Bed

AlignSupport® Coil Springs

The AlignSupport® has been carefully constructed and evolved over time to be a two stage coil. First, it senses your individual shape as you rest into the mattress, followed by an instant response that applies deep down, consistent support. Also, you can sleep soundly knowing that the spring unit is twice tempered which means it’s twice as strong and durable - impressive, we know.

ComfortCore™

The foam ComfortCore™ sits in the centre third of the mattress for added pressure relief.

InfiniLux™ Comfort Layer

A luxe, premium foam that is resilient and designed to provide long-lasting comfort you can depend on.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

Allergy UK Seal of Approval

This mattress is protected from any unwanted allergens and has the Allergy UK Seal of Approval.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

Flat Mattress

This mattress will arrive flat, not rolled and boxed.

Solid Platform Top

A solid top divan base for extra support and a firmer feel.

Storage Options Available

A wide variety of storage options make this bed as versatile and practical as it is stylish.
