Exterior fabric and quilting
Since this is the part of the mattress that will be closest to your body, it's imperative that it feels soft and comfortable. The fabric on the exterior of every Sealy mattress is carefully chosen for both feel and resilience. These two qualities are the reason your mattress will stay comfortable for years to come.
Both the 420 SealyTech innersprings and the 667 patented PostureTech™coils inside Sealy traditional innerspring mattresses create best-in-class back support. More coils supporting your whole body means you sleep better and wake up more refreshed. Our innersprings, like our sleep sets, are made to last. Our twice-tempered PostureTech™ coils retain 98% of their height and performance, resulting in a more durable mattress with longer lasting comfort. Sealy is the only manufacturer that features twice-tempered coils.
Edge Support
The Advant-Edge® System is inserted between the outer two rows of innersprings.This is the Sealy edge system, offering stability not seen in most entry-level mattress edge systems. The Advant-Edge® PLUS System* takes the stability of the Avant-Edge® and adds this premium edge system around the perimeter of the mattress so you can sleep more comfortably all the way to the edge. *select models
