Full Product Description

Say goodbye to restless nights and morning lower back stiffness. The Core 11" Extra Firm Hybrid is purpose-built to deliver steady, unyielding support without sacrificing surface comfort. If you have been struggling with mattresses that dip, sag, or sink under heavy pressure, this hybrid offers the rigid, stable foundation your body needs.

At the heart of the mattress is an 8" heavy-duty wrapped pocket coil system that responds to your body while isolating motion transfer. Topped with a high-density firm transition layer and wrapped in a breathable, quilted stretch-knit cover, the Core 11" prevents excess body sinkage while keeping your core properly supported all night.

Whether you are a back sleeper, stomach sleeper, or simply prefer a solid sleep surface, this mattress delivers reliable durability and temperature regulation for years of restorative sleep.

Frequently Asked Questions

Who is the Core 11" Extra Firm Hybrid best suited for?

This mattress is ideal for back sleepers, stomach sleepers, individuals with lower back pain, and those who dislike the deep "sinking" feeling of traditional memory foam.

Does this mattress sleep cool?

Yes. The pocketed coil base allows open air circulation through the mattress core, preventing the heat retention common in all-foam mattresses.

Will I feel my partner moving at night?

No. The pocketed coils are individually wrapped, meaning motion is absorbed locally so movement on one side of the bed does not transfer to the other.
