Overview
Beautyrest Black® Series Three Firm Mattress 15" — Queen
The Beautyrest Black® Series Three Firm Mattress 15" is a luxury innerspring mattress built for back and stomach sleepers who need firm, grounded support without sacrificing the refined finish of the Black collection. It sits at the top tier of the Beautyrest Black® lineup, layering everything from Series One and Series Two beneath a firm feel that keeps weight evenly distributed and the lumbar spine where it belongs. If you've been searching for a firm mattress for back pain relief and haven't found one that also feels genuinely refined, this is the one to lie down on. Stop by any Mancini's Sleepworld location and our sleep specialists will put it next to every competing option so you can feel the difference firsthand.
COMFORT AND FEEL: Firm feel with responsive latex contouring and coil-driven lumbar support.
SIZE: This queen sized mattress is a versatile fit for master bedrooms, couples who need undisturbed sleep, and dedicated back or stomach sleepers who want room to settle in.
BEST SLEEP MATCH: Back and stomach sleepers thrive here. The firm feel for back sleepers keeps the hips level and the spine neutral, so you stop waking up stiff in the middle.
BEST FOR: Ideal for sleepers who need firm spinal support, wake up with lower back tension, or share a bed and need true motion separation.
CONSTRUCTION SPECIFICATIONS: Triple-Stranded Pocketed Coil® Technology delivers head-to-toe individualized support and absorbs movement so a restless partner stays unfelt. Micro Diamond™ Memory Foam pulls heat away from the body all night. Self-Response™ Latex contours to pressure points while keeping airflow moving. Sleep Climate™ Technology, woven into the surface, works continuously to transfer heat away as you sleep.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Compatible with adjustable bases, platform frames, and box springs. Works with slatted platforms when slat gaps are 2 inches or less.
NOT A FIT FOR: Side sleepers who need hip and shoulder cushioning will likely find this feel too firm. Sleepers who prefer a plush or pillow-top surface should look at other Series Three options.
