The Casper Slate Firm Mattress 10.5" is a firm mattress built for back and stomach sleepers who need consistent, structured support without waking up feeling like the mattress gave up on them. Three layers of foam work together to keep your spine lifted and your sleep surface stable night after night. The Breathe Flex Foam comfort layer stays responsive so you're never locked in, while the stretch knit cover adds just enough give to let the foam do its job. Stop by any Mancini's Sleepworld location and our sleep specialists will set this next to every competing option so you can feel the difference yourself.
COMFORT AND FEEL: Firm and responsive, with surface bounce that supports back and stomach sleepers without stiffness.
SIZE: This queen sized mattress is a versatile choice for couples or single adults who want room to stretch out.
BEST SLEEP MATCH: Best for back and stomach sleepers. The firm mattress feel keeps the hips from sinking too deep, holding your spine in a neutral line all night without fighting the mattress to find your position.
BEST FOR: Ideal for sleepers who need firm mattress support for back pain relief, prefer a responsive surface over slow memory foam, or tend to sleep hot.
CONSTRUCTION SPECIFICATIONS: The Breathe Flex Foam top layer is open and responsive, releasing heat instead of trapping it. Beneath that, a foam transition layer absorbs pressure so the firm base does not feel punishing. The Casper Core base foam keeps the mattress from softening out over time. The foam is CertiPUR-US certified.
SETUP AND COMPATIBILITY: The Slate arrives rolled and compressed in a box, expands fully within a few hours, and is compatible with adjustable bases, platform frames, and box springs. No tools needed.
NOT A FIT FOR: Sleepers who prefer a plush or contouring feel will find this too firm. Not recommended for side sleepers with significant hip or shoulder pressure needs.
