Sealy Posturepedic® Plus Plainfield 15" Soft Euro Top Mattress

Sealy Posturepedic Plus Plainfield: a true soft that still holds your back

The Sealy Posturepedic Plus Plainfield in Soft Euro Top is a 3 out of 10 at 15 inches, built on the 966-coil PrecisionFit™ support system under a moisture-wicking MoistureProtect™ cover. It is the Posturepedic Plus tier: Sealy's targeted coil support and gel-foam comfort with a cushioned Euro-top, designed to sleep cool and dry. If you want a genuinely soft surface that does not let your spine fold into a hammock, start here.

What you notice in the first few minutes

Lie down and the top layers give first, the way a real 3 out of 10 should: your shoulder and hip settle into the Euro-top and gel foams. What keeps the softness honest is underneath. The PrecisionFit coils catch you before you sink too far, so your back stays in line instead of dropping, and the surface reads cool, not warm and clingy. That is the line a cheap soft bed cannot hold.

PrecisionFit™ targeted support

Sealy built its name on back support, and the Plainfield carries it with the PrecisionFit™ pocketed-coil system: 966 coils that each move on their own, supporting your spine point by point and firming up where you carry more weight. The Posturepedic Plus design encases those coils and zones them, so the lower back gets extra reinforcement exactly where most people ache. Because each coil works independently, partner movement stays contained: when one of you turns over, the other side barely registers it. A DuraFlex™ reinforced edge extends that support to the perimeter, so the usable surface runs nearly wall to wall. On a soft mattress that edge matters more than people expect: it is why a plush top still feels like the whole bed, not just the middle.

Cool, dry, and contouring

The MoistureProtect™ cover, with Surface-Guard™ Technology, wicks moisture away so the surface sleeps cooler and drier than a standard cover. Beneath it, the CertiPUR-US® certified SealyComfort™ and SealySupport™ gel foams contour to your shoulders and hips and carry heat away, and the Euro-top cushioning is sewn flush to the perimeter, so it keeps its shape over the coils instead of shifting underneath you. One honest note: a soft, cushioned top breathes a little less than a firm one, so if heat is your single biggest issue, a firmer build in this line will run cooler.

Tuned to soft, and who that fits

At a 3 out of 10 this is a true soft: deep gel-foam cushion for the shoulder and hip, with the PrecisionFit coils keeping a soft bed from sagging. That makes it a natural fit for side sleepers, for lighter-weight bodies that do not need a firm deck to feel supported, and for anyone who wants soft on top without losing spinal alignment. If you sleep mostly on your stomach or carry more weight, a soft surface can let your hips drop too far. In that case step up to the medium or firm in this same line, and the Mattress Overstock floor can walk you through both side by side.

Same bed, different names

Sealy renames this build for each retailer, so the model name changes but the mattress does not. The Plainfield is the same Posturepedic Plus bed that Mattress Firm sells as the Norman II and Sleep Outfitters sells as the Cranford Grove (matched by UPC, not by name). If you have lain on one of those and liked it, this is the bed, and worth comparing on price before you decide.

Where it sits in the Sealy lineup

Plainfield is the Posturepedic Plus tier, a step above standard Posturepedic, sitting alongside the Pro Indianapolis line, which steps the coil count up to 1,066 with MaxSupport reinforcement. Neither is simply the better mattress; the right call is the one your back agrees with. Compare firmnesses and Euro-top versus tight-top builds across the full Sealy lineup in one visit.

Living with it, and how to shop it

It needs nothing exotic underneath: a sturdy platform, close-slatted base, solid foundation, or compatible adjustable base all work. It stands 15 inches tall, so deep-pocket sheets (15 inches and up) fit best. A soft, supported, cool surface is something you confirm lying down, not from a screen, so the Plainfield Soft Euro Top is on the floor with the rest of the Sealy line across the five Mattress Overstock showrooms in Kentucky (Lexington on Nicholasville Road, Richmond, Georgetown, London, and Somerset), no appointment needed. Give it ten real minutes in your own sleep position; the 4.7-star rating from more than 500 Google reviewers across the five showrooms was earned that way. Mattress Overstock is an independent Kentucky retailer since 2012, and the associates here are paid the same no matter which brand you choose, so the guidance stays honest and never pushed toward one bed. The 90-night trial and Sealy's 10-year limited warranty hold when you buy from an authorized local dealer, delivery and setup are free, and the old mattress leaves with the team at no charge.
