Overview
Kingsdown Millhaven Extra Firm Mattress 14.5" — Twin
The Kingsdown Millhaven Extra Firm Mattress 14.5" is a hybrid mattress built for back and stomach sleepers who need a genuinely firm, extra firm mattress for back pain relief without sacrificing the body-contouring comfort that keeps pressure from building overnight. The coil-and-foam construction works from the ground up to keep the spine aligned, and the multi-layer comfort system at the surface means firm doesn't have to feel punishing. If you've been waking up stiff or sinking too far into a softer mattress, this is the one worth lying down on. Stop by any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference yourself.
COMFORT AND FEEL: Extra firm feel with flat, stable support and minimal give at the surface.
SIZE: This twin sized mattress is a smart fit for a solo sleeper, a dedicated guest room, or a growing child who needs firm spinal support.
BEST SLEEP MATCH: Back and stomach sleepers who need extra firm support to stop the hips from dropping will feel the difference here. Firm back sleepers, this one was made for you.
BEST FOR: Ideal for sleepers who need serious lumbar support, tend to overheat at night, or have been told by a doctor to sleep on a firmer surface.
CONSTRUCTION SPECIFICATIONS: The gel quilt surface pulls warmth away so you don't wake up hot. Tri-Tech Gel Infused Memory Foam adds cushioning with antimicrobial properties from graphite, silver, and copper. A resilient latex layer sits just above the coils to keep the lower back from sagging. Individually wrapped coils respond to movement without transferring it. A high-density foam encasement firms up the perimeter.
SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup available. Works with an adjustable base, platform frame, or traditional box spring. No tools needed.
NOT A FIT FOR: Side sleepers who need hip and shoulder cushioning will likely find this too firm. Not the right choice for sleepers who prefer a soft or plush feel.
