Sealy Naturals Mattresses: Shared Features

New for the 2022-2023 model year, the three models in the Sealy Naturals collection represent the most "green" mattresses Sealy has yet produced. These are hybrid beds, and while the mattress materials are not certified as organic, most are recycled and/or recyclable, and/or made from plant-based materials rather than synthetic, petroleum-based materials.

Sealy mattresses are mainly sold in stores, though Sealy does now sell direct through its website. See the Sealy store locator for a retailer in your area.

The three mattress have the same materials and construction, with the exception of the top layer of latex, which varies in softness to create the different feels/comfort levels.

Sealy names the three models "Firm, Medium, and Soft." In our evaluation, there was not as much difference in softness and cushioning depth as those names would suggest. We think the "Firm" was the firmest of the three, but on our spectrum, fell into the "Medium Firm" range. The Sealy Naturals Medium, on our scale was a little bit softer, but not much; we'd still class it as a medium firm. As for the Sealy Naturals Soft, we would classify it as a straight-up medium.

The point of all this is that none of the three is super firm, and neither is there a very soft option. Which you choose may come down to your preferred sleeping position and your weight. For example, a heavier side sleeper would probably want to go with the Soft, while a lightweight stomach sleeper would probably be better off on the Medium.

Here is a look at the features shared by all three models. Sealy also has a page on all of these materials.

Pocket Spring Support Unit

All of the Sealy Naturals mattresses use the same pocketed-spring unit employed in the Sealy Posturepedic Plus collection, with 1,072 encased coils (queen size). With this type of coil unit, we typically expect excellent motion isolation, while also providing some bounce to the bed.

All of the coil units are bordered by what Sealy calls their DuraFlex Pro Edge System--consisting of stronger edge support coils encased in perforated fabric to promote air flow.

The steel used to make the springs is 90% recycled steel, which would of course be recyclable down the road as well.

All-Natural Latex

All three Sealy Naturals mattresses have 3" of 100% all-natural Dunlop latex as the top comfort layer. This is real latex made from the sustainable harvest of rubber trees, and Ssaly has obtained certifications from the Rainforest Alliance and from the Forest Stewardship Council to that effect.

The latex is perforated with pin-core holes; these promote air flow and also have an effect on softness; Sealy varies the type of latex to create differences in softness and feel.

In addition to the top layer of latex, there's another inch of it on the bottom of the mattress, which serves as a sort-of base for the coil unit.

Natural Wool

The underside of the quilt layer features natural wool. Wool has moisture-wicking properties, and it is also a natural fire retardant. (All mattresses sold in the United States must include some kind of fire retardant layer. Many mattresses use silica, otherwise known as fiberglass, or they use fabrics treated with a chemical fire retardant.)

Adjustable Base Compatibility

All of the Sealy Naturals hybrid mattresses are compatible with adjustable bases.

Mattress Covers

The covers on these mattresses are made of a blend of organic cotton, hemp, and plant-based tencel, along with some polyester to give it some stretch. These materials have been tested for safety, and for low off-gassing. They are certified as Greenguard Gold, meaning they have been tested for their effect on indoor air quality and found to meet a high bar in terms of emissions.

Sealy is also in the process of having these materials certified by EOKO-Tex another testing authority which, along with Greenguard Gold, means that they are safe for the most sensitive uses, such as hospitals and day-care centers.

Functional Tufting

Most mattresses use glue to hold all their layers together. For its Naturals collection, Sealy employs tufting--yarns that travel through the whole mattress, anchored on both ends by a soft yarn button. These serve to hold the layers of the mattress together, allowing the company to really cut down on the use of chemical glues. According to Sealy, the tufting allows them to reduce glues by 65%.

The three Sealy Naturals mattresses are more similar than they are different, but here's our take on their differences.

Sealy Naturals Firm

The Sealy Naturals Firm is a 13" mattress. As with all of the Naturals models, it has a good bit of bounce from the coils below, plus latex is a fairly springy material. The Firm version has just a bit more surface bounce than the others.

Latex, generally, is not a material in which you tend to sink a lot, so you get more of a "sleeping on" instead of "sleeping in" your mattress feeling. So if you aren't a fan of feeling like you are sinking into your mattress, the Firm version gives you that most of that "floating on top" sensation.

Any of these models should work fine for back sleepers. Stomach sleepers will probably want to go with this Firm version. Heavier side sleepers may also opt for this one.

Sealy Naturals Medium

Sealy Naturals Soft

Of the three, this is the softest of the Sealy Naturals models, but even so, it's not a super soft, sink-in kind of bed. You're still going to get more of a floating on the top of your bed sensation than one of sinking in.

Average to lighter side sleepers will likely appreciate the Soft version, as will back sleepers who prefer a feel that's a little softer than the other Naturals mattresses.
