We had Sealy Millionaire mattresses years ago (pre-memory foam) and they were the best mattresses we had. Finally, after trying countless others, we found the new no-turn version with memory foam tops. Sid-sleepers need soft mattresses which are almost impossible to find but these do the job. Hope they last as long as they manufacturers say.

I bought this mattress as my partner was starting to suffer with an aching back in the mornings and not sleeping well. Since she has had this mattress, all her issues have gone away. Great support plus lovely comfortable feel toit.

Frequently asked questions

Is the Kingsley mattress suitable for all sleeping positions?
The Kingsley mattress is designed with an open coil spring unit that provides a firmer feel, making it suitable for back and stomach sleepers. Side sleepers may find it a bit too firm, so personal preference plays a significant role.
How often should I rotate the Kingsley mattress?
While the Kingsley is a one-sided mattress and does not require flipping, it is recommended to rotate it regularly to ensure even wear and prolong its lifespan.
What type of spring system does the Kingsley mattress use?
The Kingsley mattress features an open coil spring system, which consists of a continuous length of wire, providing a firmer support that is ideal for budget-conscious buyers.
Can you explain how the EdgeGuard technology improves the Kingsley mattress's performance?
The Kingsley mattress features Sealy's EdgeGuard technology, which consists of a high-density foam layer encircling the spring system. This design provides edge-to-edge support, preventing sagging and ensuring consistent comfort across the entire sleep surface. As a result, the mattress maintains its shape and performance over time, enhancing its durability and longevity.
What is the feel of the Kingsley mattress?
The Kingsley mattress offers a firmer feel due to its open coil construction, which provides solid support while maintaining a comfortable sleeping surface.
Can the Kingsley mattress be used on any bed frame?
The Kingsley mattress can be used on a variety of bed frames, including slatted and divan bases, as long as they provide adequate support for the mattress.
Does the Kingsley mattress have any specific cleaning instructions?
To maintain the Kingsley mattress, it is recommended to regularly vacuum the surface with an upholstery attachment to remove dust and allergens. If necessary, you can spot clean small stains with a mild detergent and water; however, avoid soaking the mattress. Always allow it to dry thoroughly before using it again to ensure longevity and hygiene.
How durable is the Kingsley mattress?
The Kingsley mattress is constructed with an open coil spring unit, which is known for its durability and ability to provide long-lasting support when properly maintained.
What materials are used in the Kingsley mattress construction?
The Kingsley mattress features a combination of innovative materials designed for optimal comfort and support. It includes Sealy's PostureTech spring system for bodyweight distribution, a Cooling Geltex layer that combines elastic gel with air-permeable foam for breathability, and EdgeGuard technology that surrounds the spring system with high-density foam for added durability and edge support.
Is the Kingsley mattress suitable for heavier individuals?
While the Kingsley mattress provides firm support through its open coil system, heavier individuals may want to consider their personal comfort preferences, as they might find it firmer than desired.
