Serta iComfort Mattress Reviews

The iComfort sleep system is Serta’s answer to the industry’s demand of a memory foam mattress that doesn’t run hot in the middle of the night. They call it their most advanced sleeping system to date, and describe a number of uniquely innovative features that justify this claim.

On the surface, it looks like this is a high end brand that should meet the needs of sensitive sleepers who want conforming support from their bed without having to deal with excessive heating, but when you’re making an investment this big, it is good to know what you’re getting into from someone other than the manufacturer.

I’ve written this guide to help you with precisely that, discussing the various aspects of this lineup in detail, and supplementing the discussion with feedback from users as well as select Serta iComfort reviews of my own.

Standout Features Of The iComfort Lineup

• Technological Innovations

Triple Effects™ Gel Memory Foam
This gel infused memory foam serves three purposes: pressure point relief, support for spinal alignment, and temperature regulation.

Cool Action™ Gel Memory Foam
This is Serta’s original gel memory foam that employs tiny gel beads for specialized support, pressure relief and thermal dissipation. Its latest iteration incorporates EverTemp™ technology to maximize its effectiveness in a wide range of temperature and humidity ranges.

EverCool® Plus Memory Foam
This is an open cell viscoelastic foam intended to provide cradling support to your body while also maintaining adequate heat dissipation. The newest version uses EverTemp™ technology to work reliably over a wider range of environmental conditions.

PillowSoft™ Foam
This is an extra-soft polyfoam that is intended to boost the cushioning support of the comfort layer of iComfort mattresses.

Deep Reaction™ Memory Foam
This is a firmer variety of memory foam that provides a heftier feel compared to the typically soft, sinking viscoelastic mattresses in the market, and is therefore used in luxury firm or extra firm models.

ActivBalance™ Support Foam
This layer of gel-infused polyfoam features a unique surface (almost egg crate like) that lets it boost the responsiveness of the ‘dead support’ memory foam layers. Its design allows it to enhance air flow.

Ultimate Edge Foam Support Core
The polyurethane support layer that Serta uses for the iComfort line features a strengthened edge to reduce roll off problems.

For the hybrid models, the support system is made out of Duet® Coil innersprings – these are carefully positioned coils designed to provide deep support and comfort for your body.

Air Suspension Technology
This is an elastic polymer layer that is intended to improve air flow while also offering bouncy support to create a moderately firm feel even in viscoelastic foam mattresses. It features reinforced edges to minimize edge roll off issues.

TempActivTM Technology
This is actually a two part mechanism, with the first being a gel foam that uses millions of temperature regulating gel beads combined with another layer of gel for support. These gel beads enable the mattress to take heat away from your body and dissipate it effectively while also boosting support.

The second is a cover material that has a dedicated thermal regulation mechanism built into its fabric, providing a surface that feels cool at the first touch. It works in conjunction with the gel memory foam to provide superior cooling throughout your sleep.

• Multiple Firmness Options
iComfort mattress models with varying degrees of firmness are available to cater to the needs of sleepers with different tastes. Serta combines various types of memory foam and regular polyfoam to achieve the different overall feels.

• Compatibility With Motion Collection Adjustable Foundations

All iComfort mattresses are designed to work with Serta’s own adjustable foundations – these allow you to change the profile of the bed so you can lie down, sit, and rest your back in an inclined position as needed.
These foundations need mattresses that can profile themselves accordingly, and often require the customer to spend time verifying the compatibility of their mattress with the foundation (or in reverse). With iComfort mattresses, you have the surety that you can set up a perfectly compatible adjustable iComfort bed configuration since both the mattress and the foundation will be from the same manufacturer.

• 120-Day In-Home Trial
Serta has partnered with various retailers to offer a generous trial program that lets you return / exchange the iComfort mattress within 120 days of purchase. You have to use it for at least 30 days, and if you’re not satisfied with its performance you can bring it back to the retailer.

Make sure that you check with the retailer beforehand whether they are part of this policy or not.

10 Year Limited Warranty
Serta maintains that their products are built to the highest of standards inside the United States, and that they have a strict QA program. To back up this claim, they offer a 10 year limited warranty on their iComfort mattresses.

However, it should be noted that they make a distinction between defects and discomfort i.e. they won’t give you a replacement if you realize, after using the mattress for a few months, that its firmness level does not fit your requirements.

In other words, you should be careful about the firmness (or plushness) at the time of purchase, and always take into account the fact that mattresses do experience some softening during the first few months.

Third Party Certifications
iComfort mattresses use only CertiPUR-US certified foams that are guaranteed to be free of harmful chemical substances that can compromise both your health and the quality of air in the bedroom. Furthermore, the iComfort lineup has won the Consumer’s Digest Best Buy for six years straight, and the Women’s Choice Award for mattresses for four years straight.

Comfort

As far as overall comfort goes, between the ability to choose from a multitude of firmness options, and the fact that both pure memory foam and hybrid models are available, there is a very good chance you’ll end up with a mattress that suits your needs in terms of support, conformity and pressure relief.

This is reflected in the generally positive feedback from the users about both the memory foam and hybrid models, but make sure you read about the durability concerns (discussed below) before you make up your mind.

Motion Isolation

iComfort mattresses yield superb motion separation, just like all other viscoelastic foam based products. The hybrid models use pocketed springs in the base, which are similarly known for their point elasticity. Motion isolation is important for people who share their bed with a partner, and don’t like to be woken up in the middle of the night because of the other person’s movements.

Some of the models also come with supporting edges to keep the sleeper from rolling out of bed.

• Temperature
Thanks to the TempActiv™ cooling mechanism used by the manufacturer, iComfort mattresses run considerably cooler than the typical memory foam mattress.

• Off Gassing Concerns
Memory foam mattress are notorious for emitting an irritating odor for the first few weeks of use. Having scoured dozens of user reviews, I’ve deduced that this isn’t a major issue with the iComfort line, since there were minimal complaints regarding this problem.

Of course, some of the more sensitive sleepers will still be able to identify the odor, but since the materials used are approved by CertiPUR-US, you can at least be assured that they won’t adversely affect your health.

• Pricing
Serta iComfort is somewhat less pricey compared to competitors such as Simmons Comforpedic, and Tempurpedic. However, it is still expensive enough to make you feel cheated if the mattress starts failing a few years in (a distinct problem that I noted in many consumer reviews).

• Durability
Although the manufacturer claims to use only the highest quality materials to make the iComfort line, it has received numerous complaints of sagging, with the process starting in a period ranging from the first few months to the first few years.
Since the manufacturer uses 4 lb/cu.ft. memory foam in the comfort layer, it is a safe assumption that this is the cause behind the sagging, as this density is a bit stingy for a viscoelastic foam mattress. I would recommend that bulky individuals consider the innerspring models with a firmer rating to get the most life out of their iComfort mattress, or stick to some other brand altogether.

Conclusion

Now that you’ve reached the end of this guide, you’ll see that Serta’s claims of innovating viscoelastic foam technology in its iComfort sleep system, to make it as cool as possible, definitely hold up. The best part is that they have memory foam varieties that have effective cooling even at relatively inexpensive price points.

However, it can also not be neglected that the iComfort series has major issues with durability, particularly where there memory foam models are concerned. They use lower density foams (presumably to keep their products cheaper than the competition), but this does sacrifice some of the hardiness of the final product, and the effects are most conspicuous with partners and / or weighty sleepers.

For this reason, I’ll advise heavier individuals to stick with the firmer versions of hybrid models with reduced heights that let the weight be effectively transmitted to the pocketed springs so the comfort layer does not take much of a beating – one such model is the Applause II Firm mattress that’s been discussed above.
