Description

The Sealy Posturepedic Sophia Flex Medium King Mattress (735571) is an Australian-designed and manufactured mattress that balances comfort and support. It is part of the “Sophia Flex” range, which is specifically engineered to be compatible with adjustable bed bases.

Key Features

• Support System: It features the 3 Stage Titanium RestSUPPORT™ coil system. These coils are designed to provide targeted support that balances stability and comfort by sensing and responding to your body’s movements.

• Adjustable Compatibility: The mattress uses FlexiCased® Edge technology, which features an articulating perimeter. This allows the mattress to flex and adjust easily with adjustable bed bases (such as Sealy’s Energise or Inspire models) while maintaining edge-to-edge support.

• Comfort Layers:

  • ComfortCore Plus: This layer includes densified memory foam and gel-infused visco-elastic layers in the center third of the mattress to target and relieve pressure in the lower back.

  • Quilt & Foam: It incorporates deep premium foam and “supersoft” quilt layers for a luxurious, pressure-relieving feel that contours to the body.

• Sleep Surface Technology:

  • SmarTex®: A fabric treatment designed to regulate temperature by wicking away moisture to keep you cool.

  • HealthShield®: An antimicrobial treatment integrated into the cover to maintain a hygienic sleep surface.

  • Premium Wool Fibre Blend: Used in the cover to promote breathability and airflow.

This mattress is designed for those who want a “medium” feel—not too soft and not too firm—and is particularly suitable if you are using, or planning to use, an adjustable bed base. As it is a single-sided mattress, it does not require flipping, though it should be rotated periodically according to standard maintenance guidelines.
