Overview
Sleepworld Express 11.5" Innerspring Medium Firm Mattress Twin XL
The Sleepworld Express 11.5" Innerspring Medium Firm Mattress is an innerspring mattress built for the back sleeper who needs real lumbar support without sacrificing surface comfort. At 11.5 inches tall, it layers a responsive pocketed coil core under a medium firm foam comfort layer, giving the spine a lifted, aligned feel from the first night. The 4-way stretch knit cover moves with you as you shift positions, so nothing pulls or binds. This is a straightforward, honest mattress that does its job well. Stop by any Mancini's Sleepworld location and our sleep specialists will put this one next to its closest competitors so you can feel the difference yourself.
COMFORT AND FEEL: Medium firm with a slightly cushioned surface and firm pocketed coil response underfoot.
SIZE: This Twin XL sized mattress is built for taller solo sleepers, college dorm rooms, and guest spaces where full-length legroom matters.
BEST SLEEP MATCH: Best for back sleepers and some side sleepers seeking a medium firm mattress for back pain relief. The coil-forward feel keeps the hips from sinking and the lumbar from rounding overnight.
BEST FOR: Ideal for sleepers who need consistent spinal support, want a mattress that holds its shape over years, or are outfitting a dorm room or guest bed.
CONSTRUCTION SPECIFICATIONS: The 4-way stretch knit cover flexes without bunching so you always feel the comfort layer beneath it. A 1.5-inch medium firm high-density foam comfort layer cushions without letting the hips sink. The 8-inch 790 pocketed coil system responds independently under each pressure point. A 3/4-inch shock-absorbing high-density base foam keeps the coils stable and the mattress from softening prematurely. Foams are CertiPUR-US certified.
SETUP AND COMPATIBILITY: Arrives rolled and compressed in a box. Unroll onto any platform frame, adjustable base, or box spring and it fully expands within hours, no tools needed.
NOT A FIT FOR: Sleepers who prefer a deep plush or memory foam contouring feel. Not designed for those who sleep hot and need active cooling layers.
