Sealy Posturepedic Plus Plainfield Medium Euro Top: the supportive medium, cool and dry
If you have wanted the back-friendly support the Sealy name is built on without going firm, the Plainfield Medium Euro Top is the one that lands in the middle. It is a 6 out of 10, a true medium, built on the 966-coil PrecisionFit support system under a moisture-wicking MoistureProtect cover, with a plush Euro-top sewn flush to the surface. Plush on top, supported underneath, cool and dry where you sleep.
PrecisionFit targeted support
Sealy built its name on back support, and the Plainfield delivers it with 966 pocketed PrecisionFit coils that each move on their own. Your spine is supported point by point, and the bed firms up where you carry more weight, answering your hips and shoulders separately instead of pushing back as one slab. That independence is also what keeps a partner's movement from carrying across the bed. A DuraFlex reinforced edge extends that support to the perimeter, so the usable surface runs nearly wall to wall and you can sit or sleep right to the edge.
Cool, dry, and contouring
The MoistureProtect cover, built with Surface-Guard Technology, wicks heat and moisture off the surface so it sleeps cooler and drier than a standard cover, a real difference for warm or restless sleepers. Beneath it, SealyComfort and SealySupport gel foams cradle the shoulders and hips and carry heat away, and the Euro-top adds a soft, tailored landing. Those gel foams are CertiPUR-US certified, so the layers you sleep closest to are tested for content and emissions.
Tuned to a true medium
At a 6 out of 10 it is a supportive medium, the most universal feel, balanced for backs and most sides. In the first minutes lying down you notice the order of the layers: the Euro-top gives first with a soft landing, the gel foams cradle your shoulders and hips, and under all of it the coils hold your spine steady so you settle in rather than sink through. It is the easiest surface for a combination sleeper to roll across. If you sleep strictly on your side and want a deep, pillowy hug, the softer Plainfield Soft Euro Top fits better; if you want a distinctly firm surface, step to the Plainfield Firm Euro Top. A medium is a compromise feel by design, and the floor team would rather point you to the right one.
The same bed sold under three names
Sealy sells this exact mattress nationally under a different model name at each retailer, an old industry habit that makes price comparison hard on purpose. At Mattress Firm it is the Posturepedic Plus Norman II 15-inch Medium Euro Top; at Sleep Outfitters and Mattress Warehouse it is the Posturepedic Plus Cranford Grove Medium Euro Pillow Top. Same Sealy build, same law tag, same manufacturer UPC (748369694583 in Queen). Here it is the Plainfield. Compare by UPC and see for yourself.
Where it sits in the Sealy line
Plainfield is the Posturepedic Plus tier, a step above standard Posturepedic, and it sits alongside the Pro Indianapolis. Both are mid-tier Sealy beds: the Plainfield carries the MoistureProtect cover and the 966-coil PrecisionFit system, while the Pro Indianapolis steps up to a 1,066-coil system with MaxSupport reinforcement. Numbers only tell you so much, so feel them side by side and compare firmnesses and tight-top versus Euro-top builds across the full Sealy lineup. If you are switching from an older innerspring gone soft in the middle, the reinforced perimeter and independent coils are the difference you notice first. At 15 inches it is a tall mattress, so deep-pocket sheets sized 15 inches and up sit best, and it works over a sturdy platform, close-slatted base, solid foundation, or compatible adjustable base.
Ten minutes beats ten reviews
Targeted support and a cool, dry surface are things you feel lying down, not things you read. The Plainfield Medium Euro Top is on the floor with the rest of the Sealy line across the five Kentucky Mattress Overstock stores (Lexington, Richmond, Georgetown, London, and Somerset, no appointment needed), where shoppers rate the team around 4.7 stars across hundreds of Google reviews. Because the floor team is paid the same regardless of brand, the guidance stays honest. The 90-night trial and Sealy's 10-year limited warranty are honored buying from an authorized local dealer, free local delivery and free setup are included with delivery usually next business day in stock, and the old mattress leaves with the team. Lie on it in Lexington this week, or select your size to see the live price.
What makes this mattress different
966 PrecisionFit Coils
A pocketed-coil support system where each coil moves on its own, supporting your spine point by point and firming up where you carry more weight, with motion kept from carrying across the bed.
True Medium, 6 out of 10
Tuned to the most universal feel: plush enough for most side sleepers, supportive enough for backs, and easy for combination sleepers to roll across.
Euro-Top Cushioning
A gusseted cushioning layer sewn flush to the perimeter for a soft, tailored landing that holds its shape over the same supportive coils.
SealyComfort & SealySupport Gel Foams
Gel-infused comfort and transition foams contour to shoulders and hips and draw heat away, so you settle in without sinking through.
MoistureProtect Cover
Built with Surface-Guard Technology to wick heat and moisture off the surface, so it sleeps cooler and drier than a standard cover.
DuraFlex Reinforced Edge
A firmer coil perimeter so the usable surface runs nearly wall to wall; sit or sleep right to the edge.
Posturepedic Plus Tier
A step above the standard Posturepedic, with the brand's targeted coil support and gel-foam comfort in a 15-inch Euro-top build.
90-Night Trial & 10-Year Warranty
The same 90-night comfort trial Sealy offers, plus Sealy's 10-year limited warranty, honored when you buy from an authorized local dealer.
Plainfield Medium Euro Top, layer by layer
This is the coil-and-foam Posturepedic Plus Euro Top build, the spring model with gel comfort foams over a pocketed-coil core, not the separate Posturepedic Plus Hybrid. Top to bottom:
- MoistureProtect cover with Surface-Guard Technology. The surface you touch first. It wicks heat and moisture away so the bed sleeps cooler and drier than a standard knit.
- Euro-top cushioning layer. A gusseted cushion sewn flush to the perimeter, the soft landing that gives first when you lie down.
- SealyComfort and SealySupport gel foams. The contouring and transition layers. They cradle the shoulder and hip and pull heat away, and they are CertiPUR-US certified, so the layers you sleep closest to are tested for content and emissions.
- 966 PrecisionFit coils. The support system. Each coil answers your body on its own, so your hips and shoulders are met separately instead of the whole bed pushing back as one slab. That independence is also what keeps a partner's movement from traveling across the mattress.
- DuraFlex reinforced coil edge. A firmer perimeter so support runs nearly wall to wall.
Stacked up: a 15-inch, true-medium surface (6 out of 10) where the Euro-top and gel foams give a soft entry and the coils hold your spine steady underneath. Sealy publishes the layer architecture; exact layer thicknesses are not all published, so they are not invented here. Ten minutes lying down tells you the rest.

Sealy's hybrid build: a cooling cover over pressure-relief comfort foams, on a targeted pocketed-coil support core reinforced exactly where you need it.
Who sleeps best on the Plainfield Medium, and who shouldn't
Combination sleepers. A true medium is the easiest surface to roll across, and the PrecisionFit coils add the rebound that makes changing positions effortless. This is the lane the Plainfield Medium is built for.
Back sleepers. Supported without feeling hard. The Euro-top relieves pressure along the spine while the coil core keeps the hips from dipping out of line.
Most side sleepers. The Euro-top and gel foams give the shoulder and hip enough room to settle, without the deep sink of a soft model. If you sleep strictly on your side and want a deep, pillowy hug, the softer Plainfield 15-inch Soft Euro Top is the better call.
Couples with different bodies. Each side gets its own answer from the independent coils, and the DuraFlex edge keeps the whole surface usable, all the way to the perimeter.
Warm or restless sleepers. The MoistureProtect cover wicks heat and moisture off the surface, the difference you notice when you stop waking up hot. If running hot is your single biggest issue, ask the floor to compare it against a cooler-sleeping build before you commit.
Who should look elsewhere. Strict stomach sleepers and anyone who wants a distinctly firm, on-top-of-the-bed feel will be happier on the firmer Plainfield 15-inch Firm Euro Top. A medium is a compromise feel by design, and the floor team would rather point you to the right one than sell you the wrong one.

Frequently asked questions
How firm is the Plainfield Medium Euro Top?
About 6 out of 10, where 10 is firmest: a true, balanced medium. The Euro-top gives a soft entry while the coils hold your spine steady, so it lands in the middle rather than feeling too soft or too stiff.
Is this an innerspring or a hybrid?
It is the coil-and-foam Posturepedic Plus Euro Top, the spring build with gel comfort foams over the 966 PrecisionFit coil support system. It is not the separate Posturepedic Plus Hybrid model. When Sealy means hybrid, the model name says Hybrid; this one does not.
Is the Plainfield 15-inch Medium Euro Top the same bed as the Mattress Firm Norman II?
Yes. It is the same Sealy mattress with the same manufacturer UPC, 748369694583 in the Queen size. Sealy gives each retailer its own model name for this bed: Mattress Firm sells it as the Sealy Posturepedic Plus Norman II 15-inch Medium Euro Top, Sleep Outfitters and Mattress Warehouse sell it as the Sealy Posturepedic Plus Cranford Grove Medium Euro Pillow Top, and here it is the Plainfield. Same build, same law tag, compare the UPC and the price.
What is the PrecisionFit coil system?
A pocketed-coil support system: 966 coils that each move independently, supporting your spine point by point and firming up where you carry more weight, with motion isolation that helps keep one partner's movement from carrying across the bed.
What does the MoistureProtect cover do?
Built with Surface-Guard Technology, it wicks heat and moisture off the surface so the bed sleeps cooler and drier than a standard cover, a real benefit for warm or restless sleepers.
How is Plainfield (Plus) different from the Pro Indianapolis?
Both are mid-tier Sealy beds. The Plainfield (Posturepedic Plus) features the MoistureProtect cover and the 966-coil PrecisionFit system, while the Pro Indianapolis steps up to a 1,066-coil system with MaxSupport reinforcement. Feel them side by side.
How is it different from the Plainfield Firm or Soft Euro Top?
The Medium is the middle of the Plainfield Euro-top lineup: softer at the surface than the Plainfield 15-inch Firm Euro Top, flatter and more supportive than the Plainfield 15-inch Soft Euro Top. Most shoppers should compare the Medium against the model one step firmer and one step softer.
How tall is it, and will my sheets fit?
It stands 15 inches tall, so deep-pocket sheets sized 15 inches and up sit best.
Do I need a special foundation?
No. A sturdy platform, a close-slatted base, a solid foundation, or a compatible adjustable base all work if you want to raise the head and feet.
Can I see it near me?
Yes. It is on the floor with the rest of the Sealy line across the five Kentucky Mattress Overstock showrooms (Lexington on Nicholasville Road, Georgetown, Somerset, London, and Richmond), no appointment needed. Free local delivery, and the old mattress leaves with the team.
