Kingsdown Millhaven Medium Firm Mattress 14.5" – Split Cal King

The Kingsdown Millhaven Medium Firm Mattress 14.5" is a hybrid mattress built for the sleeper who runs warm, wakes up stiff, or shares a bed and needs motion kept on their side. Kingsdown has been handcrafting mattresses in the USA since 1904, and the Millhaven reflects that research-driven approach: every layer is placed with purpose, not just stacked for height. The result is a medium firm hybrid that handles back pain relief without sacrificing the cushion your shoulders and hips need. If you want to feel how this compares to everything else in the room, come into any Mancini's Sleepworld location and our sleep specialists will put you on it side by side with the competition.

COMFORT AND FEEL: Medium firm with a cushioned surface that holds the spine level without pushing back.

SIZE: This Split Cal King sized mattress is built for couples who want independent firmness control on a generously long sleep surface.

BEST SLEEP MATCH: Best for back sleepers and combination sleepers who want a medium firm hybrid mattress that cushions the hips on contact and keeps the lumbar from sinking by morning.

BEST FOR: Ideal for sleepers who wake up with lower back tension, run warm through the night, or share a bed and need less motion transfer.

CONSTRUCTION SPECIFICATIONS: The gel foam quilt at the surface pulls heat away before it builds. Tri-Tech™ Gel Infused Memory Foam cradles the shoulders and hips while graphite, silver, and copper work to keep the feel fresh. A resilient latex layer sits directly above the coil system to hold the lumbar in place. Individually wrapped coils absorb movement so your partner's shift doesn't become yours. A high-density encasement keeps the edge firm.

SETUP AND COMPATIBILITY: This Split Cal King works on an adjustable base, platform frame, or traditional box spring. Delivered flat with in-home professional setup included.

NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel may find the medium firm surface too structured. Not ideal for strict stomach sleepers needing maximum resistance.
