The Ultimate Guide to Our Extra Firm King Mattress: Unmatched Support & Space

Are you searching for an extra firm king mattress that delivers on its promise of unwavering support? You're not just looking for a bigger bed—you're seeking a sleep solution that combines expansive space with the solid, supportive feel your body needs. A standard king mattress often falls short in firmness, but a truly well-engineered extra firm king can transform your sleep.

This guide breaks down everything you need to know about our ProSupport Ultra Firm King Mattress, designed for those who refuse to compromise on support or space.

Who is the Extra Firm King Mattress For?
This mattress isn't for everyone. It's a specialized solution for:

• Couples with Diverging Needs: When one partner is a heavier individual or suffers from back pain, and both need ample space.
• Stomach and Back Sleepers: Sleepers who require a solid surface to maintain spinal alignment all night long.
• Heavyweight Individuals (230+ lbs): Those who need a mattress that prevents excessive sinkage and provides robust, edge-to-edge support.
• Hot Sleepers Who Need Firmness: The combination of our cooling technologies and a firm, non-conforming surface promotes better airflow.

Engineered for Uncompromising Support: Key Features
Our ProSupport Ultra Firm King Mattress is built with a focus on durability, support, and cooling.

1. Dual-Chamber Support Core

• A base of 12.5-gauge, tempered steel pocketed coils provides a rock-solid foundation that resists sagging.
• A top layer of 2.2 PCF High-Density Extra-Firm Foam ensures a minimal contouring feel, offering the solid surface you're looking for.

2. Reinforced Edge Support System

• A king mattress demands a usable sleep surface. Our Foam-Encased Perimeter features high-density walls around the entire edge, preventing collapse when you sit or sleep near the side. This ensures you and your partner enjoy the full 76" x 80" space.

3. Cooling, Breathable Comfort Layer

• The firm feel is complemented by a breathable, moisture-wicking cover and a gel-infused graphite layer that pulls heat away from the body, ensuring you stay cool on a supportive surface.

Your Questions, Answered
Q: How firm is it, really?
A: On a scale of 1-10 (with 10 being the firmest), this mattress is an 8.5-9. It provides immediate, solid push-back with just enough cushioning to prevent pressure points, making it ideal for those who find standard "firm" mattresses too soft.

Q: Is it good for back pain?
A: Yes. By promoting excellent spinal alignment and preventing the hips from sinking, it alleviates the common causes of lower back pain exacerbated by soft mattresses. Many of our customers report a significant reduction in morning back stiffness.

Q: Will it support a heavier couple?
A: Absolutely. This is one of our primary design focuses. The high-gauge coils and ultra-dense foam are specifically chosen for their durability and weight-bearing capacity, making it an excellent extra firm king mattress for heavy people.
