Queen King Split Head Queen Split Head Plush Serta® All Mattresses
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options.

Express ShippingHow to Choose a Mattress
Choosing a mattress comes down to three decisions: what holds you up, how firm it feels, and what size fits your room and the people in the bed. Everything else follows from those. The support layer underneath determines how the bed behaves over years of use, while the comfort layers on top decide how it feels on the first night, and the two are worth judging separately. National Mattress carries innerspring, hybrid, memory foam and latex construction from Sealy, Serta, Beautyrest, Stearns & Foster, Tempur-Pedic, MLILY, Chirofoam, Springwall, Marshall Mattress, Evergreen and our own NM line.
Firmness is a fit rather than a quality rating. Side sleepers usually want medium or plush, so the shoulder and hip can sink far enough to keep the spine straight. Back sleepers usually want medium to firm, which fills the lumbar curve. Stomach sleepers want the firm end, so the hips are not allowed to drop below the ribs, and extra firm belongs there and to heavier sleepers. If you share the bed and your answers differ, a pocketed coil support system limits how much of your movement reaches the other side, and choosing a larger size does more for a shared bed than any single feature. Firmness on our mattresses runs extra firm, firm, medium and plush.
🛏 Coil, Foam, Hybrid or Latex
In a pocket coil bed each spring sits in its own fabric pocket and compresses on its own, so far less of your movement reaches the other side. A connected coil unit links the springs together for a firmer, more uniform surface at a lower price. All-foam beds contour closely and make no noise. Latex is springier than memory foam and does not hold heat the same way.
💤 Firmness by Sleep Position
Side sleepers need the surface to give at the shoulder and hip. Back sleepers want medium to firm, enough to fill the lumbar curve without flattening it. Stomach sleepers want the firm end, which keeps the hips level with the ribs. If you move between positions all night, medium is the safest place to start. Body weight shifts this too: a heavier sleeper compresses any comfort layer further and generally reads a mattress as softer than a lighter sleeper does.
👥 Sharing the Bed
Two things decide whether a shared bed works: motion transfer and edge support. Pocketed coils and a foam-encased perimeter mean far less of your movement reaches the other side, and they keep the outer few inches usable rather than collapsing when you sit on them. If one of you sleeps hot, that is a materials question, and it is worth solving on the comfort layer rather than compromising on firmness.
📏 Get the Size Right First
Size is the one decision you cannot adjust later with a topper. Measure the room, then measure the route in: stairwell turns, doorways and elevator depth are what actually stop a delivery. A queen suits most couples, a king buys shoulder room, and twin XL is the length growing teenagers and taller single sleepers need.
