Plank Luxe Hybrid Mattress

Firmness benefits

• ACA approved — endorsed by the American Chiropractic Association for spinal support and reduced back pain.
• One of the firmest hybrids available — true firm to extra-firm options that keep your back supported all night.
• Flippable design — choose Firm or Extra Firm to fine-tune feel and extend lifespan.
• Inspired by tatami mats — minimalist support with modern comfort.

More than just firm

• High-density foams — cushioning for hips and shoulders without sink.
• Optional GlacioTex cooling cover — better temperature control for hot sleepers.
• Breathable build — open-cell foams and a coil core promote airflow.
• Targeted coil support — 6″ Ascension coils for adaptive support and motion isolation.

Why we like it

• Two real firm feels in one — flip to adjust without gambling on a single firmness.
• Edge stability is legit — you can sit or sleep near the side without slide-off.
• Back-first design — the flat, supportive surface keeps posture honest for back and stomach sleepers.
• Motion stays put — coils are pocketed, so partner shift doesn’t ripple across the bed.
• Heat has an exit plan — breathable coil core plus optional cooling cover keep temps more even.
• Value is strong — durable build that outlasts most firm foam beds at the price.
