Sealy Posturepedic® Plus Plainfield 14” Medium Mattress at Mattress Overstock
The Sealy Posturepedic® Plus Plainfield 14” Medium is a balanced, medium-feel innerspring built on Sealy’s Posturepedic® Plus support system—966 PrecisionFit™ coils tuned to keep your back and hips aligned, with cushioning comfort layers on top. The title tells you the starting point—a Medium feel, 14” profile, coil support—but the showroom test is where you learn whether it fits your shoulders, hips, lower back, partner movement, and base setup.
What to compare in person
- Comfort feel: Lie in your normal sleep position long enough to feel pressure at the shoulder, hip, and lower back. Medium is the most popular feel because it works for back, side, and combination sleepers.
- Support: Compare how level your body feels here versus the firmer Plainfield Ultra Firm and the softer Plainfield Soft.
- Edge support: Sit and lie near the perimeter—the DuraFlex™ coil edge is built to hold its shape so you get the full sleep surface.
- Cooling and materials: The MoistureProtect™ cover and gel comfort foams are designed to manage surface heat; judge the feel with your own sheets in mind.
- Partner use: Test motion transfer and how easy it is to change positions on the coil system.
Questions to bring to the showroom
- What sleep position and firmness have worked or failed for you?
- Do you want a true middle-of-the-road feel, or do you lean firmer or softer?
- Will this sit on an existing frame, foundation, platform, or adjustable base?
- What delivery, setup, and old-mattress removal details apply to your address?
Same bed, different names
Sealy sells this exact mattress nationally under a different model name at each retailer—an old industry practice that makes price comparison hard. At Mattress Firm this bed is the Sealy Posturepedic® Plus Norman II 14" Medium Mattress, and it carries the same manufacturer UPC (748369694316 in Queen). At Sleep Outfitters and Mattress Warehouse it’s sold as the Sealy Posturepedic® Plus Cranford Grove Medium Mattress. Same Sealy build, same law tag—we call it the Plainfield, and the price is the part we changed. Compare by UPC and see for yourself.

What makes this mattress different
Posturepedic® Plus Support System
966 PrecisionFit™ coils are zoned to support your heaviest areas and help keep your spine aligned through the night.
DuraFlex™ Coil Edge
A reinforced coil border gives you a solid, durable perimeter—steadier edge sitting and more usable sleep surface.
SealyComfort & SealySupport Gel Foams
Gel-infused comfort and transition foams cushion pressure points while keeping you from sinking too far into the mattress.
MoistureProtect™ Cover
A cool-to-the-touch knit cover with Surface-Guard™ Technology helps manage heat and moisture at the surface.
Sealy Posturepedic Plus support is built around alignment, not just softness
Sealy tunes the Posturepedic Plus coil core and comfort layers to keep your midsection from sagging first, then builds the feel on top of that foundation.
The Plainfield 14” Medium sits in the middle of the Plainfield lineup. Compared with the firmer Plainfield Ultra Firm it gives more give through the shoulders and hips; compared with the Plainfield Soft and the Euro Top models it feels flatter and more supportive. That is the practical difference you feel in the showroom.

Back sleepers – The medium feel over a coil core keeps the hips from dipping while still relieving pressure along the spine.
Side sleepers – Enough cushioning at the shoulder and hip for most side sleepers, without the deep sink of a soft model.
Combination sleepers – The coil system adds rebound, so it is easy to move and change positions through the night.
Couples – The DuraFlex edge and responsive coils make the whole surface usable and help keep movement from carrying across the bed.

Frequently asked questions
How firm is the Plainfield 14” Medium?
We rate it 6 out of 10 (10 = firmest) – a true medium. The right fit depends on your sleeping position and whether you like to sleep more on top of the mattress or more in it.
Is the Plainfield 14" Medium the same as the Mattress Firm Posturepedic® Plus Norman II 14" Medium?
Yes — it’s the same Sealy mattress with the same manufacturer UPC (748369694316 in the Queen size). Sealy gives each national retailer its own model name for this bed: Mattress Firm sells it as the Sealy Posturepedic® Plus Norman II 14" Medium, Sleep Outfitters and Mattress Warehouse as the Sealy Posturepedic® Plus Cranford Grove Medium, and at Mattress Overstock it’s the Plainfield. Same bed — compare the UPC and the price.
How is it different from the Plainfield Ultra Firm or Soft?
The Medium is the middle of the Plainfield lineup: firmer and flatter than the Plainfield Soft and Euro Top models, but with more give than the Plainfield 13” Ultra Firm. Most shoppers should compare the Medium against the model one step firmer and one step softer.
Is it an innerspring or a hybrid?
This is the innerspring (quilted/tufted) Posturepedic Plus build with the 966 PrecisionFit™ coil support system and gel comfort foams – not the hybrid version.
Does it work with an adjustable base?
Yes, it is compatible with adjustable bases.
How fast can I get it in Kentucky?
We deliver with our own team across Kentucky, and most in-stock sizes arrive the next business day. Pickup is available at our Kentucky showrooms.
What if I do not like it after a few nights?
You have 90 days to make sure the comfort is right. We recommend giving any new mattress at least 21 nights, because the foams and cover need time to settle and your body needs time to adjust.
