Sealy Posturepedic Memory Foam Medium 12" Mattress
Couldn't load pickup availability
The honest verdict: the Sealy Posturepedic Memory Foam Medium is the all-foam bed for people who already know they love the memory-foam hug and want it at a balanced, do-anything feel. No coils. It is pressure-relief memory foam that molds to you, a transition layer, and a high-density support core, tuned to a true medium on a 12-inch profile, around a 5 out of 10. You get the conforming, motion-absorbing surface foam is loved for, with enough support for most sleepers, and a cooling cover to fight the heat solid foam tends to trap. If memory foam is the feel you are after, this is the one that suits the widest range of people.
What it is made of, and the feel that creates
Lie down and the top layer gives, then slowly cradles. Your shoulders and hips settle in, the small of your back fills in, and the pressure points that nag you on a flat firm bed quietly let go. It is a hug, not a hammock: the transition layer and dense core catch the sink before it goes too far, so you rest supported on the surface instead of buried in it. From top to bottom it is a clean all-foam build. Pressure-relief memory foam molds to your body and eases the shoulders and hips. A transition layer bridges the soft top and the firm base so the change is smooth, not a drop. A high-density support core does the job coils would, holding a true medium steady underneath you. A cooling cover counters the heat memory foam holds onto, and every foam inside is CertiPUR-US certified for content, emissions, and durability.
Who it suits, and who it does not
A true medium is the most universal feel there is, which is exactly why this bed fits so many people. Back, side, and combination sleepers all tend to land well: the medium gives a side sleeper enough room at the shoulder and hip, while the dense core keeps a back sleeper from sagging. Foam-feel lovers get the conforming surface they came for at a balanced firmness. Couples do especially well, because all-foam construction soaks up movement, so one person turning over barely carries to the other side. Here is who the Mattress Overstock team would point elsewhere, and would rather say so up front:
- If you want the bounce and airflow of coils, Sealy's hybrids like the Posturepedic Plus Albany pair foam over a coil core.
- If you want a firmer, more on-top feel, the Memory Foam Firm is the firmer all-foam version of this same idea.
- If you sleep very hot, solid memory foam runs warmer than a coil build even with the cooling cover, because a coil core moves more air. A hybrid will serve a hot sleeper better.
Coming off coils, and living with it
Trading an innerspring or a hybrid for this one means giving up lift and bounce for a quieter surface that hugs instead of pushes back. The difference shows up most in motion. Where a spring bed telegraphs every turn your partner makes, this one absorbs it, so your half of the bed stays calm while they get settled. It works on an adjustable base, so it can flex with you if you read or watch TV in bed, and it carries a 10-year limited warranty. Inside the Sealy line this Medium is the balanced middle: the Memory Foam Firm is the firmer call, and the Albany is the hybrid when you want coils.
Why buy it from Mattress Overstock
Mattress Overstock has been an independent Kentucky retailer since 2012, with five showrooms you can walk into, no appointment needed: Lexington on Nicholasville Road, plus Georgetown, Somerset, London, and Richmond. The memory-foam hug is a feel you either love or you do not, so come lie on this exact mattress for ten real minutes in your own sleeping position, and the team will set it side by side with the Firm and the hybrids so you can feel the gap for yourself. Delivery, setup, and old-mattress haul-away are free across the Kentucky service area, so the new bed arrives ready and the old one leaves the same day. Because everyone on the floor is paid the same no matter which brand you pick, the advice you get is straight, never nudged toward foam over a hybrid. Pick your size to see the live Mattress Overstock price, then compare it with the Memory Foam Firm and the coil hybrids in the Sealy lineup, and come feel the difference. A minute on your side tells you more than this whole page can.
What makes this mattress different
Pressure-relief memory foam
The top layer molds to your body and eases the shoulders and hips: the signature foam hug, dialed to a balanced medium rather than a deep sink.
Transition layer
Bridges the conforming top and the firm core, so the change from soft to supportive feels smooth instead of like dropping onto the base.
High-density support core
The all-foam foundation that does a coil's job: durable, even support that holds a true medium steady, no springs required.
Cooling cover
Counters the heat solid memory foam tends to trap, so the conforming feel stays comfortable through the night.
Excellent motion isolation
All-foam construction soaks up movement, so a restless partner's turns barely cross the bed. A strong pick for couples and light sleepers.
CertiPUR-US certified foams
Every foam inside is tested for content, low emissions, and durability, so the conforming feel is one you can trust for the long haul.
True medium, 12 inches, 90-night trial
A 5-out-of-10 feel on a 12-inch all-foam profile, adjustable-base compatible, backed by a 90-night comfort trial and a 10-year limited warranty.
The classic foam hug, balanced to a true medium
The Posturepedic Memory Foam Medium is all foam, no coils, on a 12-inch profile tuned to a true medium (about a 5 out of 10). The support comes from a dense foam base instead of springs, which is what gives it the quiet, cradling feel rather than the lift and bounce of a hybrid.
From the surface down:
Cooling cover. The outer layer counters the heat solid memory foam holds onto, so the conforming feel does not turn into a hot one.
Pressure-relief memory foam. The comfort layer molds to your body and slowly cradles it, easing the shoulders and hips and filling in the small of your back. This is the layer that creates the hug.
Transition layer. Sits between the soft top and the firm base, so the change from conforming to supportive is gradual. It also keeps you from sinking straight through to the core.
High-density support core. The foundation, doing the work coils would in a hybrid: durable, even support that holds the medium feel steady underneath you. Every foam in the build is CertiPUR-US certified.
Want it firmer? The Memory Foam Firm is the firmer all-foam version. Want coils and bounce? The Posturepedic Plus Albany hybrid. See the full Sealy lineup.
Shop the Sealy lineup →The balanced foam feel that fits the widest range
Side sleepers: the medium gives at the shoulder and hip so they settle in instead of bracing, while the dense core keeps the waist from dropping. A comfortable middle for anyone who found a firm bed too hard but a soft one too sinky.
Back sleepers: the memory foam fills in the lumbar curve and the high-density core holds the hips level, so support stays even from shoulders to seat.
Combination sleepers: a true medium is the most position-flexible feel there is, so rolling from back to side through the night does not mean fighting the mattress.
Couples: all-foam construction absorbs motion, so one person turning over or getting up barely reaches the other side. One of the better picks here for light sleepers sharing a bed.
Foam-feel lovers: if you already know you want that slow-cradling, conforming surface, this delivers it at a balanced firmness rather than a deep, hard-to-move-on sink.
Probably not for you if you want the bounce and airflow of coils (the Albany hybrid), a firmer on-top feel (the Memory Foam Firm), or you sleep very hot, where a coil hybrid breathes more than any all-foam bed.

Frequently asked questions
Is this a hybrid or all-foam?
All-foam, no coils. Support comes from a high-density foam core, with pressure-relief memory foam and a transition layer on top. If you want coils and bounce, see Sealy's hybrids like the Posturepedic Plus Albany.
How firm is it?
A true medium, around a 5 out of 10, which is the most universal feel there is. It suits back, side, and combination sleepers. If you want firmer, the Memory Foam Firm is the firmer all-foam version.
Does memory foam sleep hot?
Solid memory foam holds more heat than a coil hybrid, which is why this model uses a cooling cover to counter it. It is comfortable for most sleepers. If you run very hot, a coil hybrid moves more air and breathes better. This is one worth feeling in person.
How does it compare to the Memory Foam Firm?
Same all-foam idea, different feel. This Medium sits around a 5 out of 10 and cradles more; the Memory Foam Firm is the firmer, more on-top option. Side sleepers and pressure-relief seekers usually prefer the Medium; back and stomach sleepers who want firmer support lean toward the Firm.
Can I use it on an adjustable base?
Yes. The all-foam build flexes with an adjustable base, so it works if you like to raise your head to read or watch TV, or raise your legs at night.
Does it contain fiberglass?
The foams are CertiPUR-US certified, which tests for content, emissions, and durability. We will not guess at a fire-barrier material we cannot confirm, so if a no-fiberglass guarantee is a dealbreaker for you, ask the showroom team and we will get you a straight answer on this exact model before you buy.
Will it have a new-mattress smell at first?
Some all-foam mattresses give off a mild new-foam odor when first unwrapped, which fades over a few days with airflow. The foams are CertiPUR-US certified for low emissions. When we deliver and set it up, it is ready to sleep on.
What warranty and comfort trial come with it?
It carries a 10-year limited warranty against manufacturing defects, plus a 90-night comfort trial. If the feel is not right within the trial, you exchange it for store credit toward any bed of equal or greater value (no cash refund, and no restocking-fee games).
How do delivery and setup work?
We deliver across our Kentucky service area with our own team, usually the next business day when your size is in stock, set the new bed up, and haul your old mattress away, all free. The new bed arrives ready and the old one leaves the same day.
