Overview

Mancini's Sleepworld Onyx Medium Mattress 13" · Queen

⭐⭐⭐⭐ 4.2 · 100+ verified sleepers

The Mancini's Sleepworld Onyx Medium Mattress 13" is an innerspring mattress built for the sleeper who runs warm, wakes up stiff, and wants real coil support without sacrificing surface comfort. The best mattress for pressure point relief queen-size shoppers often overlook is one that combines active cooling at the cover with a proper coil count underneath. That is exactly what the Onyx Medium delivers, and it does it at a price that does not require a conversation about compromises. Stop by any Mancini's Sleepworld location and a sleep specialist will place this next to every competing option so you can feel the difference yourself.

COMFORT AND FEEL: Medium firmness with a cushioned surface and a coil core that keeps your hips level through the night.

SIZE: This queen sized mattress is a natural fit for couples or the single sleeper who wants room to move without crowding the bedroom.

BEST SLEEP MATCH: Side and back sleepers will feel right at home on a medium hybrid innerspring queen. The coils keep the spine from sinking while the gel-infused quilting softens the shoulder and hip contact that wakes lighter sleepers.

BEST FOR: Ideal for sleepers who sleep hot, need hip and shoulder pressure relief, or wake up feeling stiff across the lower back.

CONSTRUCTION SPECIFICATIONS: The heavyweight stretch knit cover is built to stay cool against the skin. Beneath it, two quilting layers of super soft foam and gel-infused memory foam take the edge off contact pressure. A 1" med-firm foam comfort layer and 1.5" extra firm support foam keep the midsection from bottoming out. An 840-count pocketed coil system with shock-absorbing base foam handles the rest. Foams are CertiPUR-US certified.

SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Works with adjustable bases, platform frames, and box springs. No tools required on your end.

NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel may find the Onyx Medium firmer than expected. Not recommended as a dedicated stomach-sleeper mattress.
