⚙️ Key Features
High-density encased coils move independently to target your body’s heaviest points, providing deep-down support while virtually eliminating motion transfer across the sleep surface.
A rigid, stable foam layer that prevents the lower back from bowing — providing cooling pressure relief without the "quicksand" sinking feeling of traditional memory foam.
The premium knit cover wicks moisture and heat away from your body while Surface-Guard Technology™ keeps your sleep environment fresh and hygienic over time.
A durable coil border delivers a consistent sleep surface from edge to edge and a sturdy seating surface — making it easier to get in and out of bed.
Proudly manufactured in the United States with Sealy’s traditional craftsmanship and modern sleep science — backed by a 10-Year Limited Warranty.
🩺 Is This the Right Mattress for Your Sleep Problem?
The firm innerspring core prevents the hips from sinking and keeps the lumbar spine in a neutral, supported position. The SealySupport™ Gel Foam layer adds a stable base that resists compression — the combination most frequently recommended by orthopedic specialists for lower back pain sufferers.
Unlike deep-contouring memory foam beds, the Medina II Firm provides immediate push-back and a fast response time. The "on-top-of-the-bed" feel makes it easy to shift positions throughout the night — ideal for sleepers who struggle with mobility or who wake up feeling trapped.
The firm surface keeps you sleeping on top of the mattress rather than sinking in, maximizing airflow between your body and the sleep surface. The MoistureProtect™ cover and gel foam layer actively wick and dissipate heat — a significant advantage over traditional innerspring beds.
The PrecisionFit™ encased coils absorb motion independently, preventing movement from traveling across the mattress. The reinforced perimeter edge also eliminates the "roll-off" effect, giving both partners a stable, undisturbed sleep surface.
The high-density coil system and firm foam layers provide the resistance needed to prevent bottoming out over time. This is one of the most durable configurations in the Sealy lineup — firm mattresses typically have a longer comfort life because the denser materials resist softening.
❓ Frequently Asked Questions
What is the difference between the "Medina II" and the "Dallas"?
They are the same mattress. Sealy uses different regional names for the same model across different retailers. The Medina II is the name used in our store — identical specs, construction, and warranty as the national "Dallas" model.
Is this mattress good for back pain?
Yes — the Medina II Firm is one of our most recommended models for back and stomach sleepers with lower back pain. The firm surface keeps the hips elevated and the spine in a neutral line, which is the position most orthopedic specialists recommend for lumbar relief.
What is included with White Glove Delivery?
Professional setup in your room of choice, removal of all packaging, and old mattress/box spring removal upon request — all at no additional cost.
How long does delivery take?
Delivery typically occurs within 2–3 weeks to ensure your mattress is handled with the highest standards.
