Sealy Posturepedic® Plus Plainfield 14” Soft Mattress at Mattress Overstock
The Sealy Posturepedic® Plus Plainfield 14” Soft is a plush, soft-feel innerspring built on Sealy’s Posturepedic® Plus support system—966 PrecisionFit™ coils tuned to keep your back and hips aligned, with extra cushioning comfort layers on top. The title tells you the starting point—a Soft 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. A Soft feel lets you sink in and contour, which most side sleepers and pressure-sensitive shoppers gravitate toward.
- Support: Compare how level your body feels here versus the firmer Plainfield 14” Medium and the much firmer Plainfield 13” Ultra Firm.
- 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 even on a softer top.
- 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 plush, sink-in feel, or do you lean toward something firmer underfoot?
- 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" Soft Mattress, and it carries the same manufacturer UPC (748369694408 in Queen). At Sleep Outfitters and Mattress Warehouse it’s sold as the Sealy Posturepedic® Plus Cranford Grove Soft 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 even under a soft, sink-in surface.
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
Generous gel-infused comfort and transition foams cushion pressure points and let you settle into the mattress for a plush feel.
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—so even a soft surface still has real support underneath.
The Plainfield 14” Soft sits at the plush end of the Plainfield Tight Top lineup. Compared with the Plainfield 14” Medium it lets you sink in more through the shoulders and hips; compared with the Plainfield 13” Ultra Firm it is a completely different, cushioned experience. That is the practical difference you feel in the showroom.

Side sleepers – The soft, contouring top cradles the shoulder and hip, easing pressure for sleepers who tend to wake up sore on firmer beds.
Back sleepers – The cushioned surface lets you settle in while the coil core still holds the hips from dipping too far.
Combination sleepers – The coil system adds rebound under the plush comfort layers, so it is still easy to move and change positions.
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” Soft?
We rate it 3 out of 10 (10 = firmest) – a true soft, plush feel. The right fit depends on your sleeping position and whether you like to sleep more in the mattress than on top of it.
Is the Plainfield 14" Soft the same as the Mattress Firm Posturepedic® Plus Norman II 14" Soft?
Yes — it’s the same Sealy mattress with the same manufacturer UPC (748369694408 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" Soft, Sleep Outfitters and Mattress Warehouse as the Sealy Posturepedic® Plus Cranford Grove Soft, and at Mattress Overstock it’s the Plainfield. Same bed — compare the UPC and the price.
How is it different from the Plainfield 14” Medium or the Ultra Firm?
The Soft is the plush end of the Plainfield Tight Top lineup: it lets you sink in more than the Plainfield 14” Medium, and it is far more cushioned than the much firmer Plainfield 13” Ultra Firm. If you want a similar plush feel with a taller profile, also compare the Plainfield 15” Soft Euro Top.
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.
