Sealy Posturepedic® Medina II Medium Mattress 13\" Twin

The Sealy Posturepedic® Medina II Medium is a medium mattress built for the sleeper who wakes up stiff and wants reliable back support without sacrificing comfort. A medium mattress for back pain relief, this innerspring is engineered with Sealy's orthopedic-inspired Posturepedic® Support System at its core, designed to keep the lumbar in place through the night. The MoistureProtect™ Cover works at the surface, wicking away warmth and humidity so you're not waking up damp or overheated. Constructed in the USA and backed by a 10-year limited warranty, this is a straightforward innerspring that earns its keep night after night. If you'd like to put it next to a few alternatives before deciding, the sleep specialists at Mancini's Sleepworld are happy to let you feel the difference in person.

COMFORT AND FEEL: Medium feel with a responsive coil base that supports without sinking.

SIZE: This twin sized mattress is well suited for a solo sleeper, student, or guest room where space and reliable nightly support matter.

BEST SLEEP MATCH: Back sleepers and side sleepers who prefer a medium firm innerspring will appreciate how the PrecisionFit™ Coils push back evenly, keeping the hips level and the lower back from dropping.

BEST FOR: Ideal for sleepers who wake up with lower back tension, sleep warm, or want long-term coil support without a pillow-top price.

CONSTRUCTION SPECIFICATIONS: The Posturepedic® Support System uses PrecisionFit™ Coils that flex and adjust to your body's individual needs, helping reduce Bed Aches™ over time. The Coil Edge reinforces the perimeter so the full surface stays usable. The MoistureProtect™ Cover keeps the sleep surface dry and comfortable through the night.

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

NOT A FIT FOR: Stomach sleepers who need firm resistance to keep the pelvis level, or sleepers who prefer the deep contouring feel of memory foam.

Sealy Posturepedic® Medina II Medium Mattress 13\" — Queen

The Sealy Posturepedic® Medina II Medium Mattress is a medium-feel innerspring mattress built for the sleeper who wakes up stiff and needs a medium mattress for back pain relief without losing comfort. The orthopedic-inspired Posturepedic® Support System puts PrecisionFit™ Coils exactly where your body bears the most weight, keeping the lumbar lifted so your spine stays neutral from the moment you lie down to the moment you get up. This is a tight-top innerspring constructed in the USA, backed by a 10-year limited warranty, and built to hold its feel year after year without breaking down in the center.

Come into any Mancini's Sleepworld location and our sleep specialists will put this next to every competing option so you can feel the difference firsthand.

COMFORT AND FEEL: Medium feel with responsive coil support and gentle surface cushioning.

SIZE: This queen sized mattress is a versatile fit for couples, guest rooms, and back sleepers who need consistent spinal support across the full sleep surface.

BEST SLEEP MATCH: Best suited for back sleepers and combination sleepers who prefer a medium feel. The coil responsiveness makes it easy to shift positions without that sinking, stuck feeling.

BEST FOR: Ideal for sleepers who wake up with lower back tension, run warm overnight, or want a mattress that holds its shape for the long haul.

CONSTRUCTION SPECIFICATIONS: The MoistureProtect™ cover wicks heat and moisture away so you sleep cooler without needing extra cooling layers. The Posturepedic® Support System uses PrecisionFit™ Coils to flex independently and keep your spine aligned. The Coil Edge reinforces every side of the mattress so the sleep surface stays stable all the way to the edge. Comfort foam layers in the quilt cushion pressure points without going soft.

SETUP AND COMPATIBILITY: Delivered flat with in-home professional setup available. Compatible with a box spring, platform frame, or adjustable base.

NOT A FIT FOR: Sleepers who prefer a deep, contouring memory foam feel or those who sleep exclusively on their side and need pronounced pressure relief at the hip and shoulder.

Sealy Posturepedic® Medina II Medium Mattress 13\" Twin

The Sealy Posturepedic® Medina II Medium is a medium mattress built for the sleeper who wakes up stiff and wants reliable back support without sacrificing comfort. A medium mattress for back pain relief, this innerspring is engineered with Sealy's orthopedic-inspired Posturepedic® Support System at its core, designed to keep the lumbar in place through the night. The MoistureProtect™ Cover works at the surface, wicking away warmth and humidity so you're not waking up damp or overheated. Constructed in the USA and backed by a 10-year limited warranty, this is a straightforward innerspring that earns its keep night after night. If you'd like to put it next to a few alternatives before deciding, the sleep specialists at Mancini's Sleepworld are happy to let you feel the difference in person.

COMFORT AND FEEL: Medium feel with a responsive coil base that supports without sinking.

SIZE: This twin sized mattress is well suited for a solo sleeper, student, or guest room where space and reliable nightly support matter.

BEST SLEEP MATCH: Back sleepers and side sleepers who prefer a medium firm innerspring will appreciate how the PrecisionFit™ Coils push back evenly, keeping the hips level and the lower back from dropping.

BEST FOR: Ideal for sleepers who wake up with lower back tension, sleep warm, or want long-term coil support without a pillow-top price.

CONSTRUCTION SPECIFICATIONS: The Posturepedic® Support System uses PrecisionFit™ Coils that flex and adjust to your body's individual needs, helping reduce Bed Aches™ over time. The Coil Edge reinforces the perimeter so the full surface stays usable. The MoistureProtect™ Cover keeps the sleep surface dry and comfortable through the night.

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

NOT A FIT FOR: Stomach sleepers who need firm resistance to keep the pelvis level, or sleepers who prefer the deep contouring feel of memory foam.
