Overview
Casper One Firm Mattress 11" Full
The Casper One Firm Mattress 11" is an all-foam mattress built for back and stomach sleepers who need consistent lumbar support without sacrificing comfort. A firm mattress for back pain relief, it keeps the hips from sinking too deep and the lower back from twisting out of alignment through the night. Three purposefully layered foams work together to give you responsive cushioning that bounces back the moment you shift positions.
The engineering here is straightforward and honest: no unnecessary layers, nothing that doesn't earn its place. Every foam in the stack is designed to let air move through, so warmth doesn't build up the way it can in denser memory foam builds. If you've been sleeping hot or waking up stiff, this is worth your time. Stop by any Mancini's Sleepworld location and our sleep specialists will place you directly on this mattress so you can feel exactly what the support delivers.
COMFORT AND FEEL: Firm feel with light surface bounce and stable lumbar support underneath.
SIZE: This full sized mattress is a versatile fit for solo adults, teens, and guest rooms where space is thoughtfully managed.
BEST SLEEP MATCH: Back and stomach sleepers will find firm mattress for back sleepers suits them well here. The Casper Core keeps the hips level, which is exactly what those positions need to stay pain-free.
BEST FOR: Ideal for sleepers who need firm spinal support, tend to sleep warm, or want a responsive foam feel without sinking in.
CONSTRUCTION SPECIFICATIONS: Breathe Flex Foam™ on top gives you a lively, breathable feel that responds quickly. Align Memory Foam™ in the middle eases pressure at the hips and shoulders without that slow-sink feeling. The Casper Core base keeps the mattress from softening out over time. CertiPUR-US® certified foams mean no harmful off-gassing.
SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box, expands within hours, no tools needed. Compatible with adjustable bases, platform frames, and slatted foundations.
NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel. Dedicated side sleepers needing significant shoulder pressure relief may want a softer option.
