In the pursuit of better sleep, one name is standing out for all the right reasons. The Sealy Posturepedic Elevate Blackwood has been awarded the prestigious Which? Best Buy—a trusted seal of approval from the UK’s leading consumer review organisation. But what makes this mattress more than just a comfortable choice? It’s a masterclass in sleep engineering, handcrafted in Britain and built to last.
Why the Which? Best Buy Matters
Which? Best Buy mattresses are independently tested for comfort, durability, and performance. The Elevate Blackwood scored among the highest-rated Sealy models ever reviewed, making it a standout choice for anyone serious about sleep.
Support that Starts at the Core
At the heart of the Elevate Blackwood lies the AlignSupport™ Coil, a patented spring system exclusive to Sealy. This innovative coil features a unique geometry that senses your body as it meets the mattress, offering an immediate response followed by deep-down support. It’s twice-tempered for durability, ensuring consistent performance year after year.

Comfort, Crafted to Perfection
Sealy’s comfort architecture is more than just layers, it’s a bespoke support system of bespoke materials, hand selected and tested to deliver. Combined with a double layer of firm and extra firm foams, the Elevate Blackwood Extra Firm mattress delivers maximum support and a truly robust feel. This model is purpose-built for those who demand the firmest level of comfort and support.
The mattress is finished in luxurious textiles that are not only beautiful but also built last the distance. Each fabric is carefully chosen for its tactile quality and long-lasting performance, ensuring your mattress looks and feels exceptional for years to come.
Edge-to-Edge Excellence
Thanks to UniCased®, the Elevate Blackwood offers superior edge support. This perimeter system reinforces the entire mattress edge, expanding your usable sleep surface and eliminating that “rolling off” sensation. It also prevents sagging and lateral movement, preserving the mattress’s shape and structure over time.


Smart Sleep Technology
- SmarTex®: This advanced fabric technology is woven into the surface layer to disperse heat away from your skin, helping you stay cool and comfortable throughout the night.
- ProShield®: Endorsed by Allergy UK, this naturally derived treatment protects against allergens, keeping your mattress clean, fresh, and hygienic.
Handmade in Britain, Built for Real Life
