Sealy Posturepedic Plus Plainfield: a true medium that holds your back and sleeps cool The Sealy Posturepedic Plus Plainfield in Medium is a 6 out of 10 hybrid at 14", built on the 966-coil PrecisionFit™ support system, a gel-memory-foam comfort layer, and a moisture-wicking MoistureProtect™ cover. This is the Posturepedic Plus tier: Sealy's targeted coil support and gel-foam comfort in a clean build made to sleep cool and dry. If you want one bed that does the universal things well and holds your back without feeling like a board, start here. PrecisionFit™ targeted support, layer by layer Sealy built its name on back support, and the Plainfield delivers it with the PrecisionFit™ pocketed-coil system: 966 coils on an 8-inch encased core that each move on their own, supporting your spine point by point and firming up where you carry more weight. Lie down on your back and the bed meets you evenly in the first minute, hips and shoulders settling in while the middle stays held, so you are not folding into a hammock. A DuraFlex™ reinforced coil edge carries that support to the perimeter, so the usable surface runs nearly wall to wall: sit on the edge to tie your shoes or sleep right out to it and it holds, which matters more than people expect on a shared bed. Cool, dry, and contouring The MoistureProtect™ cover with Surface-Guard™ Technology wicks moisture so the surface sleeps cooler and drier than a standard cover, and it resists the dust-mite dander, mildew, and odors that build up over years. Beneath it, a half-inch of SealyComfort™ gel memory foam cradles your shoulders and hips, then responsive SealyComfort™ and SealySupport™ gel foams carry that contour into the coils and draw heat away. Because the gel comfort sits over a coil core rather than a deep slab of foam, air moves through the bed: you get the cradle without the trapped, sinking-in warmth an all-foam mattress of the same feel builds over a night. The foams are CertiPUR-US® certified. Tuned to medium, and who it suits At a 6 out of 10 it is a supportive medium, the most universal feel, the kind most bodies settle into on the back, the side, or both. The PrecisionFit coils respond to each side independently, so two people of different sizes can share it and each get the support they need, with partner movement staying reasonably in check when one of you turns over. It is the honest pick for the unsure buyer and for couples who sleep differently. If you are a strict, heavier side sleeper who wants a deep plush cradle, or you prefer a firm, very flat surface, feel a softer or firmer Plainfield first. Same bed, different 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 14" Medium; at Sleep Outfitters and Mattress Warehouse it is the Posturepedic Plus Cranford Grove Medium. Same Sealy build, same manufacturer UPC (748369694316 in Queen). The Plainfield is that bed under the Mattress Overstock name. Compare it by UPC, then check the price. Where it sits in the Sealy lineup Plainfield is the Posturepedic Plus tier, a step above standard Posturepedic. It sits alongside the Pro Indianapolis, which steps up to a 1,066-coil system with MaxSupport reinforcement for a firmer feel. Neither is simply better, so it pays to feel them side by side across the full Sealy lineup. At 14" plan on deep-pocket sheets (14" or deeper); a sturdy platform, close-slatted base, solid foundation or box spring, or a compatible adjustable base all work with the hybrid. Ten minutes beats ten reviews Targeted support and a cool, dry surface are things you feel lying down. The Plainfield Medium is on the floor across the five Mattress Overstock showrooms in Kentucky (Lexington on Nicholasville Road, Richmond, Georgetown, London, and Somerset), no appointment needed, so give it ten honest minutes on your back and your side. Mattress Overstock is an independent Kentucky retailer that has been doing this since 2012, and the associate helping you is paid the same no matter which brand you pick, so the guidance is straight. The 90-night comfort trial on select Sealy models, plus the 10-year limited warranty are honored when you buy from a local authorized dealer; if the comfort is not right, you exchange for store credit toward another bed rather than a cash refund. Free local delivery and setup are included, and the old mattress leaves at no charge. Select your size to see the live Mattress Overstock price, or lie on it in Lexington this week.
