Note: This is not a review. This is our plain-English explanation and overview of the current Serta iComfort Hybrid mattresses for 2020. Also see our overview of the all-foam Serta iComfort series, which mirrors the Hybrid line but features a foam support rather than coils.

Serta iComfort Hybrid Mattresses

Serta's iComfort Hybrid line has been redesigned for the 2020 model year, and now directly reflects its non-hybrid all-foam iComfort mattresses. The two product lines use the same model numbers, the same foams and memory foams, and the same cooling technology. The difference is the hybrid line's use of a pocketed-coil support unit rather than a foam support base for the regular iComfort line.

From a features standpoint, a coil base means that these hybrid models have a lot more bounce than the all-foam versions. You'll also find better airflow, since air can flow more freely around steel springs than it can in a solid chunk of foam.

The iComfort Hybrid collection from Serta includes 4 models, two of those with two different comfort levels, so 6 mattresses in total. These new 2020 versions replace the previous iComfort models from 2018-2019.

With all of its 2020 iComfort mattresses, Serta introduced some new foams with a variety a features intended to help you sleep cool. Serta indicates the extent of each model's cooling features with embroidered snowflakes on the side panel of each mattress.

The mattresses also vary a little by height, by cooling features, and by price.

iComfort Memory Foams

Serta has introduced a new set of memory foams used in the 2020 iComfort and iComfort Hybrid models, and the differences in feel between the models come down to the combination and amount of the foams used in each, as well as the type of coil unit. Here's a rundown of the new memory foams Serta is using. In addition to these, you'll see a more standard gel memory foam, called Gel Active Max, used in the mattresses; this foam is similar to earlier generations of Serta's gel memory foams.

Serta uses the same top foam layers in both hybrid and non-hybrid versions. For example, the CF1000 and the CF1000 Hybrid use the same combination of comfort foams, but one has a solid foam support unit while the other uses a pocketed coil unit at the bottom.

Carbon Fiber Memory Foam

This new-for-2020 foam is a slow responding one with lots of that melting, memory foam feel. It's infused with carbon fibers; carbon (like graphite) is a known conductor, and its use in this foam is meant to channel heat away from the body.

We've been starting to see carbon used in foam mattresses, but most commonly, we've seen it as carbon dust; Serta is instead using longer fibers, which might better help heat travel compared to dust.

Here's a look at that carbon fiber foam. It's included in all of the iComfort mattresses, both regular and hybrid.

UltraCold System Memory Foam

A variation of the Carbon Fiber Memory Foam, Serta's "UltraCold System" is comprised of the same carbon fiber-infused foam, but with an added layer of phase change material on top.

We have seen phase-change coatings used more and more often in mattresses; you can liken it to wax beads covered in a casing. When cool, they feel noticeably cool to the touch, and it takes much longer for your body to warm them than it would a plain foam. This type of phase-change coating is intended to keep you feeling cooler longer while you fall asleep.

Here's what the phase-change coating look like on top of the UltraCold System foam.

Air Support Foam

The other notable new memory foam from Serta is its Air Support Foam. It's still a memory foam, but it's scored into hollowed-out cubes. Here, Serta is creating some air flow, much in the same way as egg-crate foam or even springs. There's simply less material, and more opportunity for air to move through and around the foam.

The Air Support Foam is used in just the two CF4000 Hybrid mattresses (as well as the non-hybrid CF4000 foam models), and we noticed it helps creating more cushioning and conformance, along with noticeable pressure relief.

Here's a look at the Air Support Foam.

Pocketed Coil Support Units

The iComfort Hybrid collection all feature a pocketed coil support unit with 1,025 coils in a queen-size bed. Serta varies the spring strength to change up the firmness levels of the mattresses. Firmer coils are used in the line's firm mattresses, such as the CF2000 Hybrid and the CF4000 Hybrid Firm, while softer coils are used in the company's Medium and Plush versions.

You'll find plenty of deep bounce in all these beds. The top foams tend to absorb motion up near the surface, but once you drop your weight on the bed, you'll notice the bounce. (By contrast, the non-hybrid iComfort models have almost no bounce at all).

Around the edge of the bed on all four sides is a foam edge support, intended to boost stability right along the edge.

Serta iComfort CF1000 Hybrid

The base model in the iComfort Hybrid series, the CF1000 comes in just one comfort level, and contains just one type of memory foam, the Carbon Fiber Memory Foam. Serta calls this mattress a Medium, and it's using the softer of Serta's two coil units.

The feel of this bed is extremely similar to that of its non-hybrid counterpart. While it does give you some slow-melting memory feel, it has the least amount of that feel in the series. Aside from the carbon fiber foam, it has no additional cooling features.  However, this is not a mattress with very deep cushioning -- we felt more of a 'floating-on-top' feel, so more of your body will be exposed to the air.

Serta iComfort CF2000 Hybrid

Stepping up in the line, the 12" tall CF2000 Hybrid includes the same Carbon Fiber Memory Foam included on all of the new iComfort mattresses, but adds Serta's Gel Active Memory Foam as well. Like carbon, gel is a known conductor of heat, so it's intended to add some extra heat-dissipation qualities.

The CF2000 is classed as a Firm by Serta, and it's using their firmer coil support unit.

Since the iComfort CF2000 has two foams with cooling properties, Serta gives it two "snowflakes" as an indication of those features.

Serta iComfort CF3000 Hybrid

Continuing up the line, the 12.5" tall CF3000 Hybrid substitutes Serta's UltaCold System memory form for the Gel Active Foam. The layer of phase-change material on top of that foam gives it a palpable coolness to the touch. The CF3000 Hybrid also gets a new cover with cooling properties. Serta called is the "Max Cold" cover, and it includes fiber that do give it a coolness to the touch.

The iComfort CF3000 Hybrid comes in two softness levels: Medium and Plush. With both, though, you do experience more cushioning depth and conformance compared to the CF1000 and CF2000 mattresses.

The CF3000 Hybrid, since it has three cooling features (the carbon fiber memory foam, the phase change coating, and the cooling cover), gets three 'snowflakes' printed on the side panels.

Serta iComfort CF4000 Hybrid

The top of the line iComfort Hybrid mattress is the CF4000 Hybrid, available in two softness levels, Firm and Plush. These have all of the cooling features of the CF3000 mattresses, and add the Air Support Foam, with its hollowed-out cube-shaped cells of memory foam. It also adds height -- for a total of 13.5" inches.

The Plush version is definitely the softest of the iComfort Hybrid mattress, with the deepest cushioning and a lot of that slow, melting into the bed feel -- the most of any of the iComfort beds.
