 Serta iComfort Blue 100 Mattress

Overview: Serta iComfort Blue 100 Mattress

Last Updated: September 2018

The iComfort Blue 100 mattress from Serta is somewhat unique today, in that you can purchase one directly online through Serta, or buy it though major mattress stores. Either way, the price is the same. The iComfort line was introduced in 2017 by Serta. This model we review here is the entry-level (and least expensive) mattress in the line, the Blue 100 Gentle Firm (it's available in just one version).

The Serta Blue 100 mattress has a fairly common construction, with about 2.75" of gel memory foam on top, followed by two more layers of progressively firmer polyurethane foams. The mattress comes shipped to you fully expanded, whereas most online mattresses these days come compressed into a box.

Something to keep in mind: this Serta mattress is available in a lot of places, so shipping and returns will vary depending on the retailer. If you order directly from Serta, you get free white-glove delivery to the room of your choice, plus setup and removal of all the packaging. If you order from a local store, or through Amazon, the retailer's own shipping and returns policies will apply, which may or may not include the "white glove" service.

While a 120-night trial period in advertised, keep in mind there's a $200 pickup fee plus a 15% disposal fee should you decide to return the mattress if you ordered directly through Serta.com (see Serta return policy). That differs quite a bit from most online-only mattress brands, which generally include free returns within the trial period. Again, that's if you order from Serta directly. Policies at other online stores or in your local mattress shop might be different, so it's worth checking.

While the shipping and return policies might be confusing, an advantage is that you can actually try out the Serta iComfort Blue 100 in a store before you buy, which could be an advantage for those not comfortable with ordering a bed sight unseen.

From a performance perspective, we found the iComfort Blue 100 to be especially good for back sleepers. And if you are sensitive to a partner's movements on the bed, you may be reassured that we found motion isolation to be excellent. We were also impressed with edge support on this mattress; with a lot of memory foam beds, we find ourselves 'melting' off the side of the bed when sleeping right on the edge. But the Serta iComfort Blue 100 mattress has an effective foam edge support that kept us feeling stable.

With almost three inches of slow-responding memory foam, this bed definitely has that melting-into-the-mattress feel you associate with memory foam, but it's not as deep or quicksand-like as other mattresses. So if you like the feel of memory foam, but don't like the 'stuck in a hole' feeling that sometimes comes with it, this Serta mattress might suit you.

Among our concerns: We questioned support and spinal alignment for heavier side and stomach sleepers (200+ lbs.) who might sink through the Serta mattress's comfort layers and end up resting on the much firmer foam layers below.

We also had some questions around value. The iComfort Blue 100 mattress from Serta competes in a crowded online field of many similar 10" foam and memory foam beds, a number of which retail for a bit less. Compared to mattresses you might see in a store, we think the Serta iComfort Blue 100 mattress goes toe-to-toe with competing brands, but less so when compared to companies that sell mattresses directly online.

You can use the Serta iComfort bed on any suitable and supportive foundation. Serta sells a matching foundation, but it's not required. It can also be used on an adjustable foundation. Serta sells several adjustable base units, but again, none are a required purchase.

Read on for our detailed report and be sure to check out the video to see this mattress in action as we put it through our tests. You can always visit the company's website for more on the iComfort Blue 100 Mattress from Serta.

 

Construction

Mattress type:  Gel Memory Foam over Foam

Made In:  United States

Mattress Thickness:  10”

Mattress Weight:  51 lbs (queen size)

 

Layers

The Serta iComfort Blue 100 mattress is a 10″ thick bed comprised of 4 layers of foam (listed below from top to bottom)

  • 3/4" gel-flecked memory foam
  • 2" "Evercool" gel memory foam
  • 1" polyurethane transition foam
  • 6" polyurethane support foam with firmer edge-support foam
The top two layers are what we consider the comfort layers of the mattress. The topmost layer of memory foam is fairly quick responding and is flecked with gel intended to help channel heat from the body. The thicker second layer of memory foam also contains gel, and is both softer and slower responding than the top layer. After that, you have an inch of transition foam that's made of standard polyurethane, and below that a 6" block of polyurethane support foam.
Serta has chosen not to disclose the densities of the foams used in the iComfort Blue 100 bed. We typically use foam densities to estimate longevity and compare the bed to others. We do have a clue based on the total weight of the queen size iComfort Blue 100 of 51 pounds; some competing foam mattresses weigh 20 or 30 pounds more, leading us to guess that the foam densities in this mattress may be lower than that of the competition (lower density foams tend not to last as long).

 Foam Layers on the Serta iComfort Blue 100 Mattress

Cover

The layers of the Serta iComfort Blue 100 mattress are wrapped in a nice, stretchy cover. We thought it felt a bit like a heavy sweatshirt material, very soft and cozy.

Comfort & Feel

There are three aspects that make up our assessment of comfort and feel. We call these "preference-based characteristics" because no rating here is better or worse – rather, the attributes that are most desirable to you will be determined solely by your personal preferences. We apply the same classification standards to each mattress so you can more easily compare apples to apples.

Softness ( what’s this )

Keep in mind that what mattress companies call “firm” or “soft” is a purely a preference. All mattresses should be supportive and promote healthy spinal alignment. Whether a mattress is fluffy and squishy (what mattress companies call soft or plush), or less so (what companies call firm), is purely down to your personal needs and preferences.

Serta calls the iComfort Blue 100 a "gentle firm" mattress. That seemed in line with what we would call a Medium, maybe slightly towards a firmer medium. It was almost a little hard to characterize since the top two memory foam layers are quite soft, but the support coming from below is quite firm. Altogether we'll stick with Medium as our assessment.

Not sure what softness is best for you? Take our Mattress Match Quiz and find out.

Softness Level
(1=Least Soft, 9=Most Soft)
5 Medium

 

Cushioning Depth ( what’s this )

This refers to how deeply you sink into the mattress or feel cradled or hugged, versus a feeling of floating on top of the bed. Because of the two soft layers of memory foam on top of the mattress, we'd call cushioning slightly deeper than average, with a bit of that "hugged" feeling.

Cushioning Depth
(1=Shallowest, 9=Deepest)
6 Slightly deeper than average

 Serta iComfort Blue 100 Cushioning Depth

Responsiveness ( what’s this )

Responsiveness refers to how quickly a mattress recovers its shape after being compressed. When you press your hand into the mattress, for instance, then remove it, does it take several seconds for the mattress to return to flat, or does it recover immediately?

The Serta iComfort Blue 100 mattress does have almost 3 inches of memory foam, and it is a fairly slow responding foam, so you do get a good bit of that melting-into-the-bed feeling.

Typically with all-foam beds, there isn't a lot of bounce, and the iComfort bed from Serta is no exception. When our tester dropped his weight to the bed, he barely bounced at all.

Response Rate
(1=Slowest, 9=Fastest)
3 Slow response, no bounce

 

Back Support & Pressure Relief

The two things that you should always be sure to get from your mattress are spinal alignment (commonly thought of as "back support") and pressure relief. Unfortunately, no mattress will deliver these two things equally well for all sleepers. In particular, spinal alignment and pressure relief capabilities will vary across sleepers with different weights, body shapes, and sleep positions. To help you determine how this mattress will perform for you, we break down our spinal alignment and pressure relief assessments by sleeper type.

In our evaluations, the Serta mattress offered very good support especially for back sleepers, and for lighter weight side and stomach sleepers.

 

Spinal Alignment

The key to good back support is maintaining proper spinal alignment while you sleep. This means that the mattress should hold your spine in roughly the same position it's in when you're standing. The ability of a given mattress to do this will generally depend on your weight, sleep position, and body shape.

Here is how we break down the spinal alignment of the Serta iComfort Blue 100 mattress:

Weight Range Back Sleepers Side Sleepers Stomach Sleepers
Lighter <150 lb 9 8 7
Average 150 to 200 lb 9 8 7
Above Average 200 to 250 lb 9 7 6
Heavier >250 lb 9 6 6

 

Back Sleepers:

Our tester felt very supported in this position, and we felt that most people would feel similarly well supported in this position regardless of weight. Because of the soft layers on top, lighter people will probably experience the Serta iComfort Blue 100 mattress as a softer mattress, while it may feel firmer to heavier individuals.

Side Sleepers:

When it came to side sleeping, our tester felt good. His shoulders were able to get into the mattress enough to create good spinal alignment. As his body began to warm the memory foam, he felt himself sinking further in, which for a person of his weight was fine. We questioned, however, what would happen for heavier people, who might sink through the soft memory foam layers to the firmer and less pressure-relieving layers below.

Stomach Sleepers:

For stomach sleeping, our 200 pound tester felt good, but did feel his hips starting to sink just a bit more than he would have liked. When your hips sink too much in the stomach-sleeping position, you can create too much arch in the back which can lead to back pain down the road. We think that for those lighter than our tester, who are occasional stomach sleepers, the Serta iComfort mattress should be fine, but for heavier individuals, it may not be suitable, as hips could sink too low in this position.

 

Pressure Relief

When a mattress pushes back against your body with too much force in a concentrated area, the result can be pain, soreness, loss of circulation, excessive tossing, and other problems. In general, such "pressure points" are of greatest concern for side sleepers, since that's the position in which your body's weight is distributed over the smallest surface area. To find the right mattress for your needs, keep in mind that the pressure-relieving capabilities of any given mattress will vary depending on the sleeper. Factors like your weight and body shape (e.g., broader shoulders and/or hips) will determine how far you sink into the mattress, and the pressure relief offered by that mattress will vary widely at different depths.

Here's how we sized up the pressure relief of the Serta iComfort Blue 100 mattress:

Weight Range Typical curves Extra curvy
Lighter <150 8 8
Average 150 to 200 8 8
Above Average 200 to 250 7 7
Heavier >250 6 6

Similarly as with side sleeping in general, we found that pressure relief with the Serta mattress is dependent on body weight and curves.

Other Characteristics

Beyond the preference-based characteristics of comfort and feel, and the body matching for spinal alignment and pressure relief, a mattress will have a number of other attributes that can make it a better or worse choice for you. We call these "priority-based characteristics" because they are areas in which a mattress can be better or worse, but that will have differing amounts of importance to each sleeper. So, determining how much importance to give to these features will be entirely a matter of your own personal priorities. As always, we apply the same ratings standards to each mattress so you can more easily compare apples to apples.

 

Motion Isolation ( what’s this )

With a bowling pin standing upright on the Serta iComfort memory foam bed, we dropped a bowling ball on it to gauge how movements on one side of the mattress might be transferred to other areas. The pin barely moved. When our tester dropped his body to the bed, the pin also barely moved.

In general, foam and memory foam beds are good choices if you are easily disturbed by a partner's movements, and the Serta mattress is no exception.

Motion Isolation Rating 10 /10 Exceptional

 

Temperature ( what’s this )

Memory foam has a reputation for heat retention, so this is always something we examine with foam beds. In the case of the Serta iComfort mattress, cushioning isn't as deep as with some memory foam beds, so more of your body is exposed to air, meaning there's less chance of overheating.

The top two layers of memory foam are infused with gel, and gel is a known conductor, so the memory foam here is intended to help channel heat from your body.

If overheating in bed is an issue for you, and you’ve experienced it with other mattresses, other models have features that are specifically intended to address this, and a foam bed in general is likely is not your best choice.

Stays 'Cool' Rating 5 /10 Average for foam

 

Edge Support ( what’s this )

Foam mattresses aren’t typically very supportive along the very edge of the mattress—important if you like to sit on the edge of the bed, or if you tend to sleep along the edge. The Serta iComfort Blue 100 mattress does have firmer foam on both sides of the bed, and in our tests, it was quite effective. Our tester felt very stable both while sitting on the edge, and while laying on the edge of the mattress.

Edge Support Rating 8 /10 Very good for foam

 Serta iComfort Blue 100 Edge Support

Ease of Repositioning ( what’s this )

Ease of movement can also be an issue with memory foam especially the type of slow-responding memory foam used in the Serta mattress. But our tester did not feel hindered in rolling from side to side on the bed.

Repositioning Rating 7 /10 Above average for memory foam

 

Green Features ( what’s this )

For mattress shoppers concerned with the use of natural materials, sustainable manufacturing practices or the like, we offer our subjective evaluation of any efforts taken by the company to make the mattress more green, healthy, or safe. 

In the case of the Serta iComfort Blue 100 mattress the company makes no claims about the use of natural materials. However all of the foams used are certified to the CertiPUR-US standard, which verifies that a material has low VOC off-gassing as well as a lack of chemicals and other substances regulated by the CPSC.

Green Rating 5 /10 Does have some safety certifications

 

Adjustable Base Compatibility ( what’s this )

We tested the Serta iComfort mattress atop our adjustable bed frame, and had no issues. The foot tended to lift up, but that is very typical for a brand new mattress. Given a break-in period, in our experiences, mattresses will relax and conform to the foot of the bed.

Adjustable Base Compatibility 8 /10 Very good compatibility

What You’re Getting

The Serta iComfort Blue 100 bed is a 10" memory foam over foam mattress made by a company with a long history in the mattress business. The top two layers of memory foam (2.75" total) are infused with gel to help regulate heat, and the mattress is wrapped in a sturdy and nice-feeling cover.

 

How Long We Think It Will Last

When it comes to estimating the comfort lifespan of a mattress, we tend to use foam density as our best, albeit imperfect, predictor of how long a foam will retain its shape and resiliency. In the case of the iComfort Blue 100 mattress, Serta has chosen not to disclose the densities used. However, the total weight of the queen size version-51 pounds- is very light compared to similarly constructed competing mattresses, which typically weight 20 to 30 pounds more. That tells us that the foams used in the Serta mattress are not as dense as much of the competition. Generally, denser foams should hold up better in the long run.

 

Overall Value

Pricing for the queen size Serta iComfort Blue 100 mattress is $1,099, a price that's a little higher than some competing memory-foam-over-foam beds sold from online companies. When compared to what you might find in a mattress store, this Serta bed is comparable, and ultimately that's who may appreciate this mattress most--those who are uncomfortable buying a mattress online without trying it in a store.

However, we are concerned by Serta's trial and refund policy. While a 120-night trial is comparable to the competition, a $200 return fee plus 15% disposal fee is not.

Value Rating 6 /10 Average value

 

Delivery, Returns, & Warranty

Delivery

  • Free delivery with white glove service from Serta.com

Delivery and setup will vary depending on where you purchase the iComfort Blue 100 mattress, so check before buying.

 

Returns

  • 120-day trial period through Serta.com
  • $200 return fee plus 15% disposal fee

Serta does offer a 120-day trial period through purchases made online, but not that there is a hefty fee for returning a mattress. Again, return policy will differ depending on where you purchase the mattress, so check before purchasing. Serta returns.

 

Warranty

  • Warranty Length: 10 years
  • Indentation Coverage: 3/4” and above

One of the biggest, if not THE biggest complaints about any mattress from consumers regards body impressions—the inability of a mattress to spring back, eventually creating a low spot/sinkhole in the mattress. As such, mattress warranties all contain a term defining how big a sag or ‘body impression’ (measured when no one is on the mattress) is considered a defect, and thus covered under the warranty. The industry standard for mattresses is generally between ¾” and 1.5”. Serta has chosen to cover indentations that meet or exceed 3/4” which is better than average among foam beds. Practically speaking, that means any softening or sagging would need to be at least that deep before the warranty would offer you protection. See: Serta warranty.
