Overview
Beautyrest Black® Series Three Firm Mattress 15" Eastern King
The Beautyrest Black® Series Three Firm Mattress 15" is a luxury innerspring mattress built for back and stomach sleepers who want serious support without a punishing feel. As the third tier of the Beautyrest Black® collection, it layers every feature from Series One and Series Two, then adds Self-Response™ Latex for responsive pressure relief and an upgraded cooling cover that actively moves heat away from the body through the night. The coil system works independently under each zone of the body so the person next to you never feels you shift. If you want to feel this mattress against every other option on the floor, the sleep specialists at Mancini's Sleepworld will set it up side by side so you can feel exactly what the difference is.
COMFORT AND FEEL: Firm feel with a quilted surface that supports without pressing back.
SIZE: This Eastern King sized mattress is a strong fit for couples or single sleepers who want generous space and room to stretch out fully.
BEST SLEEP MATCH: Back and stomach sleepers are the natural fit here. The firm mattress for back sleepers keeps the spine level and the hips from sinking, which means you wake up without that familiar morning stiffness.
BEST FOR: Ideal for sleepers who run warm, carry tension in the lower back, or need the spine held in a neutral line through the night.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology moves with each part of the body independently, so support never feels stiff or uniform. Micro Diamond™ Memory Foam pulls heat away from the body while you sleep. Self-Response™ Latex breathes and bounces back, relieving pressure without trapping warmth. SurfaceTouch™ Gel Memory Foam is quilted directly into the surface for immediate cushion on contact.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Works on an adjustable base, platform frame, or box spring. No tools needed for base assembly.
NOT A FIT FOR: Side sleepers who need deep hip and shoulder cushioning, or anyone who prefers a plush or pillow-top feel.
