We check out the iComfort Hybrid collection of memory foam and pocketed coil mattresses.

Note: This is not a review. This is our plain-English explanation and overview of the current Serta iComfort Hybrid mattresses. Also see our overview of the Serta iComfort series of foam and memory foam beds. We also have an in-depth review of the entry-level iComfort mattress, the Blue 100CT Gentle Firm.

Serta iComfort Hybrid Mattresses

Serta's popular iComfort mattresses includes two series of all-foam beds, the Blue and the Blue Max collections. We cover those in a separate article.

There's also an iComfort Hybrid series, which we discuss in this article. These beds feature memory foam over a pocketed coil support unit, and Serta calls this collection Blue Fusion.

The collection debuted in 2018 with 11 available models with varying firmness levels and mattress heights. Mattress heights range from 12" to 16" and prices for a queen-size bed range from $1,099 to $2,799. Here's how they break down:

Pocketed Coil Unit

All of the models in the Serta iComfort Blue Fusion series share the same pocketed coil unit, using some interesting coils that blend a few coil-making techniques. (Check the video for a close look if you're a coil geek.)

Serta intersperses these special coils throughout the mattress; about one out of every five pocketed coils are the special coils. There are 1,008 pocketed coils total for a queen size mattress.

Depending on the particular model, Serta varies the softness or firmness of the coils to effect the overall feel of the bed.

Memory Foam

Serta is using their TempActiv gel memory foam in these beds. It's a slow-responding foam -- meaning it has a lot of that slow, melting feel you expect from memory foam. It's worth noting, however, that the TempActiv foam isn't as slow responding as Serta's TempActive Max memory foam that's used in its iComfort Blue Max non-hybrid models. So if you're looking for maximum memory feel, you might want to check our overview on the regular Serta iComfort models.

The TempActiv (and the TempActiv Max) memory foam includes gel and phase-change material, meant to help it feel cool, and we did think it felt cool to the touch.

In the example below, both foams were squeezed and released at the same time -- the TempActiv Max is slower to come back to shape. In a practical sense, that means the TempActiv Max will have more of that melting-into-the-bed sensation.

Mattress Covers

The iComfort Hybrid series have a very traditional mattress look, with quilted covers that, even in the firmer models, have a plushness to them. The fabric is a soft and stretchy jersey, similar to the fabric used in the non-hybrid Serta iComfort lineup.
The iComfort Hybrid 100 and 200 models have the same cover. The 300 and 500, and all of the 1000+ models include some phase change material in the covers meant to make them cool to the touch. We did think it was effective -- we could feel the cooling effect even through clothing while sitting on the bed.

Warranty information for each mattress is included on the mattress "Law Label" at the store, and vary depending on the model.
