Description

Experience pressure-relieving sleep with the Sealy Advantage Memory Essential Mattress. Designed to bring you a fine blend of memory foam comfort and medium-firm support.

Innovative support

Made with Sealy's unique PostureTech Core Support spring system, this mattress actively supports the heaviest parts of your body whilst gently getting firmer and applying support where it is needed most. These brilliant springs provide long-lasting, deep targeted support.

Cocoon comfort

Sink into a deep sleep with a plush layer of the MemorySense® memory foam, specifically designed to wrap you up in cocoon-like comfort throughout the night. This special foam reduces tossing and turning to help you stay asleep so you can wake up feeling fully rested.

With a medium to firm feel, you can get the perfect blend between comfort and support!

If this firmness isn't for you, check out the Sealy Waltham Advantage Latex Mattress for a medium feel.
