The Serta iComfortPro Mattress Level One Medium is an all-foam mattress built around 5 support zones, up to 2 inches of naturally-derived latex foam, and a cool-to-the-touch fabric. It is the entry point of the iComfortPro line, listed at $1,999.00, and it targets sleepers who want a premium foam feel without coils. If you want zoned support for spinal alignment, responsive latex rather than slow memory foam, and a surface that stays cool to the touch, this is the model to look at first.

Who is the Level One Medium for?
The Level One Medium suits sleepers who want an all-foam mattress with structured zoning rather than a uniform slab of foam. Serta describes it as a medium-feel, 12-inch mattress with 5 zones designed for improved spinal alignment in any sleep position. It is made for all sleep positions, which makes it a reasonable default for combination sleepers who shift between their back and side during the night. The latex foam responds to movement instead of sinking slowly, so you get contouring without the stuck-in-the-mattress feeling that memory foam can create.
This model is also aimed at people who care about heat. The quilted top uses CoolFeel Pro Fabric, described as cool to the touch, and the latex foam is naturally breathable. Serta states directly that latex does not trap heat the way synthetic foams can. If you have found yourself waking up warm on a traditional memory foam mattress, the material choice here is the main reason to consider this build.
It is worth noting who this is not for. The Level One is an all-foam mattress, so sleepers who prefer the pushback of coils will not find them here. Serta also sells the same line in an Extra Firm feel, and the Medium is only one of the two options at this level. If you sleep primarily on your stomach and want a strongly structured surface, the Extra Firm version of Level One is the one Serta points to for that preference.
What does the construction actually include?
The Level One Medium is built in layers that each do a specific job. The top is a quilted cover with CoolFeel Pro Fabric for a cool-to-the-touch surface. Underneath sits PillowSoft Aire, which Serta describes as providing enhanced cushioning and promoting airflow through a gently rippling design. The comfort layer is 2 inches of naturally-derived True Response Latex Foam, measured on the queen size, which gives the mattress its responsive, breathable character. The base is the 5 ZoneResponse Design, which alternates firmness levels across the surface to keep the body in natural alignment.
Here is how the key specifications break down:

The CertiPUR-US certification means the foam was tested for and is free from harmful chemicals and gasses. Serta also advises against applying liquids to the mattress, since moisture or chemicals applied directly to the surface can cause premature breakdown of the foam.
How does the 5-zone design change the feel?
The 5 ZoneResponse Design is the defining feature of this mattress. Rather than using one consistent firmness across the whole surface, Serta alternates levels of firmness in five ergonomic zones. The intent is to give targeted comfort and support where the body needs it most, which is what keeps the spine in natural alignment whether you sleep on your back, side, or stomach. For a side sleeper, this typically means more give at the shoulders and hips and firmer support at the waist. For a back sleeper, it means the lumbar region does not collapse into the foam.
The latex foam works alongside the zoning rather than against it. True Response Latex Foam responds to movement and to the natural curves of your body, which gives you pressure relief without the slow contouring of memory foam. Serta positions latex as more breathable and longer-lasting than memory foam, and notes that it comes from rubber trees, making it naturally durable, non-toxic, and breathable. If you have ever felt trapped in a memory foam mattress when trying to turn over, the responsive character of latex is the practical difference you will feel here.
The Medium feel sits between the Extra Firm option and the plusher feels found higher in the iComfortPro line. It is a balanced choice for couples with different sleep positions, and it is the version Serta describes as offering a medium-feel supportive sleep surface for a restorative night.
How does it handle cooling and motion?
Serta addresses cooling on two fronts: the CoolFeel Pro Fabric on the quilted top and the breathable latex foam underneath. The brand states directly that these two elements work together to help you sleep comfortably cool throughout the night. The PillowSoft Aire layer adds to this with its rippling design that promotes airflow through the comfort layers. For sleepers who run warm, the combination of a cool-to-the-touch surface and open-cell latex is the core cooling story of this mattress.
On motion, Serta describes the Level One Medium as designed to minimize the impact of your partner’s movement. As an all-foam mattress with no coils, it is built to absorb movement rather than transfer it across the surface. If you share a bed with a partner who gets in and out during the night, this is the category of mattress where foam generally performs well.

What does it cost and what do the terms cover?
The Serta iComfortPro Level One Medium is listed at $1,999.00. It is available in Twin XL, Queen, King, and Cal King. Serta also publishes where Level One sits in the wider iComfortPro line: Level 1 starts at $1,499, Level 2 starts at $2,099, and Level 3 starts at $3,499. The $1,999 figure is the specific price for this Medium model, while the $1,499 starting figure covers the Level One range as a whole, including the Extra Firm feel.
The purchase terms are straightforward. Serta offers a 100-Night Trial, with a 100-Day In-Home Trial specifically for purchases made directly on Serta.com. If you decide the mattress is not right for you within that window, you contact Serta by phone or email and they coordinate a return. Shipping is free, and the mattress is covered by a 10-Year Limited Warranty that handles manufacturing and workmanship defects.
Compared to the Saatva Classic, which carries a 365-night home trial, free white-glove delivery with in-room setup and old-mattress removal, and a lifetime warranty, the Serta terms are shorter on trial length and warranty duration. The Saatva Classic also comes in three comfort levels and two heights, which gives you more firmness options on a single product page. If trial length and delivery service matter as much to you as the feel of the mattress, that comparison is worth reading in full.

Who should not buy the Level One Medium?
Skip this mattress if you want the pushback of coils. The Level One is an all-foam build, and Serta positions it as a premium all-foam sleep experience. Sleepers who prefer an innerspring or hybrid feel, or who want the bounce that comes with a coil support core, should look at Serta’s hybrid lines instead. The same applies if you want a pillow top: Serta explains that a pillow top is an additional layer of padding sewn into the top of the mattress, and the Level One is not sold with one. Pillow top options appear at Level 2 and Level 3 in the iComfortPro line.
Also skip it if you need a trial longer than 100 nights or a warranty beyond 10 years. Those terms are what Serta publishes for this model, and they are shorter than what some competitors offer. If you are a heavier sleeper who needs a mattress engineered for higher weight capacities, this model is not positioned for that use, and you should compare specifications carefully before ordering.
Finally, consider skipping it if you want to compare multiple firmness options on one product page. Level One offers Medium and Extra Firm. If you want Plush, Plush + Pillow Top, or a wider range of feels, those are found at Level 2 and Level 3.
How does Level One compare to Level Two and Level Three?
Serta publishes the differences between the three iComfortPro levels directly. Level 1 starts at $1,499 and features 5 support zones with up to 2 inches of professional-grade latex foam and an advanced cooling system, available in Medium and Extra Firm. Level 2 starts at $2,099 and includes all the benefits of Level 1 plus up to 5 inches of professional-grade latex foam, with additional cooling and latex upgrades available, in Plush, Plush + Pillow Top, and Extra Firm. Level 3 starts at $3,499 and adds up to 13 inches of professional-grade latex foam plus graphite-infused latex foam, in Plush, Plush + Pillow Top, and Firm.
The practical read: Level One is the value entry, Level Two adds more latex depth and more feel options, and Level Three is the premium build with the most latex and the graphite infusion. If you already know you want a medium-feel all-foam mattress with zoned support and you do not need a pillow top, Level One covers the core of what the line offers at the lowest price.

What is the Saatva alternative?
The Saatva Classic is the natural alternative if you want coils, a longer trial, and white-glove delivery. It is an innerspring mattress with a 3-inch Euro pillow top, a dual-coil design made of triple-tempered recycled carbon steel, and patented Lumbar Zone Technology for spinal alignment. It comes in three comfort levels: Plush Soft at 3/10, Luxury Firm at 5-7/10, and Firm at 8/10, and in two heights, 11.5 and 14.5 inches. The cover is a breathable blend that includes organic cotton and is treated with Guardin botanical antimicrobial treatment.
The terms are where the two diverge most clearly. Saatva advertises a 365-night home trial, free white-glove delivery with in-room setup and free old-mattress removal, and a lifetime warranty on the mattress for as long as the original purchaser owns it. The Saatva Classic is also endorsed by the American Chiropractic Association and uses CertiPUR-US certified foams and GREENGUARD Gold certified materials.
The choice comes down to build and terms. The Serta iComfortPro Level One Medium is an all-foam mattress with latex comfort layers and 5 zones, listed at $1,999.00 with a 100-night trial and 10-year warranty. The Saatva Classic is a coil mattress with a Euro pillow top, three firmness options, and substantially longer trial and warranty terms. If you want foam with responsive latex, the Serta is the better fit. If you want coils, more firmness choices, and longer protection, the Saatva Classic is the one to check.
Verdict
The Serta iComfortPro Level One Medium is a strong pick for sleepers who want zoned, responsive latex foam in an all-foam build, with a cool-to-the-touch surface and a 100-night trial. Choose the Saatva Classic instead if you want coils, three firmness levels, free in-room delivery, and a lifetime warranty.

FAQ
Does the Level One Medium sleep cool?
Serta states that the CoolFeel Pro Fabric on the quilted top and the naturally breathable latex foam work together to help you sleep comfortably cool throughout the night. The PillowSoft Aire layer also promotes airflow through its gently rippling design. Latex foam is described by Serta as not trapping heat the way synthetic foams can, which is the material-level reason this build is positioned as a cooler all-foam option.
Is the Level One Medium good for couples?
Serta describes the Level One Medium as designed to minimize the impact of your partner’s movement, which is the standard benefit of an all-foam construction with no coils to transfer motion. The Medium feel is also a balanced option for couples who sleep in different positions, since the 5 zones are designed to support the body in any sleep position. If you and your partner disagree on firmness, note that Level One only comes in Medium and Extra Firm, so there is no plush option at this tier.
What is the difference between the Medium and Extra Firm versions?
Both are Level One models with the same 5-zone design and up to 2 inches of latex foam. Serta describes the Extra Firm as designed for those who prefer a strong, structured sleep experience, while the Medium is described as a medium-feel supportive 12-inch mattress. The choice comes down to how much surface give you want: Medium gives you more contouring, Extra Firm gives you a flatter, more rigid platform. Both are available at the Level One tier.
Can I return the mattress if it does not work for me?
Yes, for purchases made directly on Serta.com. The 100-Day In-Home Trial lets you contact Serta by phone or email within the trial window to coordinate a return. Serta notes that this trial applies only to purchases made on Serta.com, so if you buy through a retailer, the retailer’s own return terms apply. Shipping is listed as free shipping and returns for this model.
