Overview
Mancini's Sleepworld Onyx Medium Mattress 13" · Eastern King
The Mancini's Sleepworld Onyx Medium Mattress 13" is a hybrid mattress built for the sleeper who runs warm and needs genuine pressure relief without giving up support. If you've been waking up stiff, or you're sharing a bed with someone who tosses and turns, this is the mattress built to fix both problems. The Onyx Medium sits at a price point that punches well above its class, delivering coil-based support and gel-infused comfort in one 13-inch package. Come see it in person at any Mancini's Sleepworld location and our sleep specialists can put it next to every competing option so you feel the difference yourself.
COMFORT AND FEEL: Medium feel with a cushioned surface that contours to your body while the coil core keeps your spine in line.
SIZE: This Eastern King sized mattress is a generous 76 by 80 inches, built for couples or solo sleepers who want full room to stretch out.
BEST SLEEP MATCH: Side sleepers and combination sleepers will appreciate this medium hybrid mattress for pressure point relief, with the pocketed coils keeping the lumbar lifted so you don't wake up tight.
BEST FOR: Ideal for sleepers who run hot, need hip and shoulder cushioning, or share a bed and don't want to feel every time their partner moves.
CONSTRUCTION SPECIFICATIONS: The cover is a heavyweight stretch knit that actively draws warmth away from the surface. Beneath it, a gel-infused memory foam layer cushions pressure points and keeps heat moving. The fabric-wrapped pocketed coil system absorbs motion and follows your body's contours. Dense high-density support foam at the base keeps this mattress from breaking down early. Foams are CertiPUR-US certified.
SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup included. Compatible with adjustable bases, platform frames, and traditional box springs. No tools required for setup.
NOT A FIT FOR: Sleepers who prefer a plush or pillow-top feel may find the medium firmness too structured. Strict stomach sleepers needing extra-firm support should consider the Onyx Extra Firm.
