The Cathedral Cove is Sealy's firm innerspring mattress built around densely packed encased coils and gel foams. Individually wrapped coils cut motion transfer, and the StableEdge Pro system plus SealyStability encased coils hold the perimeter so the edge stays usable. A CoreSupport center adds memory foam under the heaviest part of the body, and the knit cover uses MoistureProtect and Surface-Guard to wick moisture and resist odors and allergens. It suits back and stomach sleepers and couples who want a firm, bouncy, edge-stable bed rather than a sinking all-foam feel; it is made in the USA.

Owner feedback on Sealy's firm encased-coil mattresses is generally positive on support and edge stability, with couples noting less motion transfer. The most common complaint is that the firm feel is harder than expected, especially for side sleepers.
This innerspring mattress combines SealyStability™ encased coils with the StableEdge™ Pro system for edge-to-edge support. A CoreSupport™ center adds an extra layer of memory foam under the heaviest part of the body.
Layers of Sealy® gel foams sit over densely packed encased coils. The feel is firm, with conforming support and a breathable build. Each coil is individually encased in fabric, so it moves independently. This reduces motion transfer and gives a more stable surface. The encased coils also reinforce the edges, which improves durability and flexibility when the mattress is paired with an adjustable base.
The cover is a soft, durable knit fabric with MoistureProtect™ moisture-wicking to help you stay cool. Surface-Guard Technology™ protects the surface from odors and staining caused by bacteria and common allergens. The mattress is designed, assembled and tested in the USA.
