Vs softer mattresses: The Blackwood's firm feel gives noticeably more support and less sink than a softer mattress, while ComfortCore™ still provides targeted pressure relief exactly where it's needed. If you're a back or front sleeper, or a heavier sleeper who needs dependable support, this is the better choice. Softer mattresses suit side sleepers or those who want a more plush, cushioned surface.
Vs medium mattresses: This mattress offers noticeably firmer, more consistent support than a medium mattress, thanks to the AlignSupport™ Coil and BasePlank foundation. Medium mattresses suit a broader range of sleeping positions, while the Blackwood is built specifically for those who need a firmer, more supportive feel.
Vs premium and luxury mattresses: This mattress shares the same patented AlignSupport™ Coil technology and ProShield® treatment found in higher-priced Sealy ranges. The difference is typically in the depth and number of comfort layers, rather than any compromise in spring quality or craftsmanship.
The Blackwood is backed by Sealy's 7-year manufacturer's guarantee against defects in materials and workmanship. Given the patented AlignSupport™ Coil construction, this is a mattress designed to last - the guarantee reflects that.
National Bed Federation (NBF) Approved - Independently verified to meet strict UK standards for quality, safety and responsible manufacturing.
ProShield® Treatment - Endorsed by Allergy UK - Independently endorsed by Allergy UK, confirming the anti-allergen treatment meets recognised standards for reducing allergen exposure.
The Blackwood delivers dependable firm support with genuine cooling and allergen protection, backed by Sealy's patented AlignSupport™ Coil technology. If you're a back or front sleeper looking for a supportive, breathable mattress, this is well worth a closer look.
