The Casper Slate Firm Mattress 10.5" is a firm mattress built for back sleepers and stomach sleepers who need a surface that holds them up rather than lets them sink. It is Casper's entry-point all-foam mattress, and it earns its place in the lineup with a firm mattress for back pain relief that is easy to live with every night. At 10.5 inches, it sits at a practical height that works with most standard bed frames and foundations. If you want to feel it before you commit, our sleep specialists at Mancini's Sleepworld are happy to put this one next to comparable options so you can sense the difference for yourself.
COMFORT AND FEEL: A firm, lightly responsive foam surface that holds the lumbar in place without feeling rigid.
SIZE: This twin sized mattress is a great fit for kids' rooms, first apartments, and solo sleepers who want firm support in a compact footprint.
BEST SLEEP MATCH: Best suited for back sleepers and stomach sleepers. The firm feel keeps the hips level and the lower back supported, which is exactly what those positions need.
BEST FOR: Ideal for sleepers who need extra-firm support, tend to feel unsupported on softer foam, or wake up with lower back stiffness.
CONSTRUCTION SPECIFICATIONS: The top layer is Breathe Flex Foam™, an open-cell foam that allows air to move through as you sleep. A middle transition layer eases the shift from surface to base. The firm Casper Core base holds its shape over time, keeping the mattress from softening out in the center.
SETUP AND COMPATIBILITY: Arrives rolled and compressed; expands within a few hours with no tools needed. Compatible with adjustable bases, platform frames, and slatted foundations. Box spring not recommended.
NOT A FIT FOR: Side sleepers who need hip and shoulder cushioning may find this feel too firm. Sleepers who prefer a slow, deep-sink sensation will not find it here.
