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.

Sleepworld Express 11.5\" Innerspring Medium Firm Mattress Queen

The Sleepworld Express 11.5\" Innerspring Medium Firm Mattress is a medium firm innerspring mattress built for the back sleeper who needs dependable lumbar support without waking up feeling like they slept on a board. It earns its place in a crowded value category by pairing genuine coil-based support with comfort foam that actually does something, not just softens the surface. If you have been shopping a medium firm mattress for back pain relief and want something that holds its shape year after year, this one is worth lying on. Stop by any Mancini's Sleepworld location and a sleep specialist will put this next to every comparable option so you can feel the difference before you decide.

COMFORT AND FEEL: Medium firm with a responsive, slightly lifted feel that keeps the spine supported all night.

SIZE: This queen sized mattress is a generous 60 by 80 inches, a strong fit for couples sharing a master bedroom or solo sleepers who like room to stretch.

BEST SLEEP MATCH: Built for back sleepers, and some side sleepers who prefer a firmer surface. The medium firm feel keeps the hips from sinking while still taking the edge off pressure points at the shoulders.

BEST FOR: Ideal for sleepers who wake up with lower back stiffness, want a responsive coil feel instead of foam sink, or need a mattress that holds its shape through years of use.

CONSTRUCTION SPECIFICATIONS: The stretch knit quilt panel moves with you rather than pulling tight when you shift positions. Beneath it, 1.5 inches of medium firm high-density comfort foam cushions without going soft. An 8-inch, 790-pocketed coil system handles targeted support and keeps motion from traveling across the bed. A shock-absorbing high-density base layer holds everything in place so the support feels consistent well past the first year. Foams are CertiPUR-US certified.

SETUP AND COMPATIBILITY: Arrives rolled and compressed as a bed-in-a-box, expands within hours, no tools needed. Compatible with adjustable bases, platform frames, and box springs.

NOT A FIT FOR: Sleepers who prefer a deep plush or pillow-top feel will find this too firm. Those needing a soft pressure-relief surface for side sleeping at the hip should consider a softer option.

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.
