Overview
Kingsdown Millhaven Extra Firm Mattress 14.5" Split Cal King
The Kingsdown Millhaven Extra Firm Mattress 14.5" is a hybrid innerspring mattress built for back and stomach sleepers who rely on a firmer extra firm mattress for back pain relief and proper spinal alignment. A gel foam quilt sits right at the sleep surface, drawing heat away before pressure can build. Beneath it, Tri-Tech Gel Infused Memory Foam™ works with graphite, silver, and copper infusions to keep sleep cooler and fresher night after night. A resilient latex layer sits just above the coil system, delivering targeted lumbar support without letting the lower back sink or round. Our Mancini's Sleepworld sleep specialists can walk you through every option in this lineup so you can feel the firmness difference for yourself before you decide.
COMFORT AND FEEL: Extra firm with a flat, structured surface that holds the spine level all night.
SIZE: This Split Cal King sized mattress is a smart fit for taller couples who want independent firmness control on each side.
BEST SLEEP MATCH: Best for back and stomach sleepers who prefer an extra firm feel. The flat, minimal-give surface keeps the hips from sinking, so the spine stays aligned from shoulder to heel.
BEST FOR: Ideal for sleepers who need strict spinal support, run warm through the night, or wake up with persistent lower back tension.
CONSTRUCTION SPECIFICATIONS: The gel foam quilt at the surface pulls heat away the moment you lie down. Tri-Tech Gel Infused Memory Foam™ adds graphite, silver, and copper for antimicrobial cooling comfort. A latex lumbar layer supports the lower back precisely. The 904Q individually wrapped coil system moves per zone, and the Full Body Surround high-density foam encasement keeps the edge stable.
SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup available. Compatible with adjustable bases, platform frames, and box springs. No tools needed for assembly.
NOT A FIT FOR: Sleepers who prefer any cushioning or plush feel at the surface. Side sleepers needing hip and shoulder pressure relief may find the extra firm feel too restrictive.
