Overview

Kingsdown Millhaven Extra Firm Mattress 14.5" Split Top Queen

The Kingsdown Millhaven Extra Firm Mattress 14.5" is a hybrid mattress built for back and stomach sleepers who need an extra firm mattress for back pain relief and wake up stiff without real structural support underneath them. At 14.5 inches tall, it layers gel-infused quilt comfort over an individually wrapped coil system with a resilient latex zone positioned precisely at the lumbar, so the lower back stays lifted rather than left to sink. The result is a mattress that holds its shape under sustained body weight without feeling punishing. If you want to feel this next to other Kingsdown options before you buy, the sleep specialists at Mancini's Sleepworld can walk you through every firmness side by side.

COMFORT AND FEEL: Extra firm feel with a cooled gel surface and a coil system that keeps the spine aligned.

SIZE: This Split Top Queen sized mattress is two independent Twin XL halves, allowing couples to customize each side independently without sacrificing shared space.

BEST SLEEP MATCH: Best for back sleepers and stomach sleepers. The extra firm feel keeps the hips from dropping and the lumbar from rounding, which is exactly what firm mattress for back sleepers need to stop waking up sore.

BEST FOR: Ideal for sleepers who need serious lumbar structure, run warm through the night, or share a bed and want to move without waking their partner.

CONSTRUCTION SPECIFICATIONS: The gel foam quilt at the surface keeps heat from pooling against the skin. Tri-Tech Gel Infused Memory Foam™ uses graphite, silver, and copper to cushion shoulders and hips while staying fresh and cool. A resilient latex layer above the coil system targets the lower back directly. The Full Body Surround Encasement System keeps the edge firm from corner to corner.

SETUP AND COMPATIBILITY: Delivered flat with professional in-home setup available. Compatible with an adjustable base, platform frame, or box spring. No tools needed for standard placement.

NOT A FIT FOR: Not the right choice for side sleepers who need hip and shoulder cushioning, or for anyone who prefers a softer, contouring feel.
