iComfort Blue 100 Memory Foam Mattress by Serta

The Serta iComfort Blue 100 memory foam mattress features a soft contouring gel memory foam top, gel-infused memory foam sub-layers, and an edge-maintaining and roll-off stopping base layer. The Blue 100 offers a balanced comfort level, leaning towards the softer side, and is priced at the introductory level of the iComfort lineup. We found this mattress to be pretty incredible and are excited to tell you all about it.

The iComfort series by Serta offers a lineup of memory foam mattresses designed for comfort and priced for several different budget ranges. The iComfort Blue 100 Gentle firm is rated as a 4-5/10 firmness, features Serta’s TempActiv™ Gel Memory Foam and Ultimate Edge® foam base. The Blue 100 is the introductory model in the iComfort family and is priced in the $1,110 range. The main difference in this model compared to the more expensive ones is the lack of Serta’s Deep Reaction™ Memory Foam and Air Suspension™ Technology.

The iComfort Blue 100 features several layers of foam to provide a balanced sense of support and comfort.


The iComfort takes a balanced approach to provide comfort and back support. This mattress makes use of several different layers to provide a dynamic and adaptive contour support. Each layer is designed with a specific benefit in mind and, as a collective, they all work to provide a cool and comfortable night’s rest.

Layer One: ¾” TempActiv™ Gel Memory Foam

The first layer is Serta’s renowned TempActiv Gel Memory foam that’s designed to provide all the benefits of gel memory foam and better temperature control. Keeping things cool is always an important concern when it comes to memory foam mattresses. The iComfort passes with flying colors; largely because of this ¾” thick layer.

Layer Two: 2” EverCool® Fuze™ Memory Foam

The second layer down is a 2” thick layer gel-infused memory foam that is designed by Serta with breathability in mind. This layer is very similar to the top layer but created in such a way that helps offer better pricing for this introductory iComfort model.

Layer Three: Serta Balanced Support Foam

The third layer is a fairly generic foam, again to help reduce cost on the introductory model, that is included to help balance out the plushness of the memory foam. While memory foam offers often-superior contouring it can easily feel too soft without added support. This 1″ thick layer rests just below the memory foam to help provide that “just right” balance between comfort and support.

Layer Four: 6″ Ultimate Edge Foam

This bottom-most layer offers ample support for the entirety of the mattress and helps support optimal weight distribution. Serta’s Ultimate Edge system is designed to avoid edge-sagging and prevent rolloff when one gets too close to the edge. Base layers are often where manufacturers choose to “cheap out” and save cost. The iComfort memory foam mattresses are no such cheapskates.


The iComfort mattress is available in both memory foam and hybrid memory foam designs. Our review here is only of the memory foam model and not meant to describe the hybrid. With that in mind, the iComfort memory foam mattress is available in several different models as well. Each offers something special and you might fight it useful to compare their variations.

Blue 300 Firm

The iComfort Blue 300 by Serta

Features a 4-layer foam design supported by a foam core base, priced around $1500 for a queen size bed. This mattress features a TempActiv top layer, and EverCool memory foam layer, support foam, and deep reaction memory foam layers all resting on a solid Ultimate Edge foam base. Overall thickness is 11.25″, which is slightly more than the Blue 100. This mattress is advertised as an 8/10-10/10 firmness by Serta.

Blue Max 1000 Cushion Plush

Features a 5-layer comfort foam design supported by a foam core base, priced around $1700 for a queen size bed. Again, this mattress features a topmost layer of the TempActive gel memory foam, followed by 2 separate layers of EverCool memory foam, a layer of 2″ thick support foam, and a 7″ foam core base. This mattress is best characterized by its double layers of Supreme Memory Foam which accommodates a softer overall comfort level. This mattress is advertised as a 2/10-4/10 firmness by Serta.

Blue Max 1000 Cushion Firm

The iComfort Blue Max 1000 Firm Features Several Layers of Targeted Foam and Memory Foam for a much Firmer Comfort Level

The Blue Max 1000 Firm has a 1″ thick TempActiv top layer, four more layers of foam and memory foam for a firmer comfort level, and rests on a 6″ Serta Ultimate Edge Foam Core layer. This mattress is similar to the Blue Max 1000 Plush but makes use of additional memory foam layers near the top of the mattress for a firmer comfort level, but not too firm. Advertised as a 5.5-7.5/10 firmness.

Blue Max 3000 Elite Plush

The iComfort Blue Max 3000 Elite Plush Features Serta’s Air Suspension™ Technology

The Blue Max 3000 Elite Plush features many of the same types of foam and memory foam layers as its kindred comparatives. The main discerning feature of the Elite series is the Air Suspension™ Technology layer that rests just above the Ultimate Edge foam support base layer. This layer is designed to help promote an even lighter, softer, and cooler comfort level than other Blue-series mattresses.

Blue Max 5000 Elite Luxury Firm

We’ll be honest: there is a trend among the iComfort mattresses that the more buzzwords in the name—the higher the price. The Blue Max 5000 Elite Luxury Firm mattress boasts the largest number of buzzwords and is correctly characterized as the “top-of-the-line” among iComfort models. This mattress is best understood by its double layers of Deep Response memory foam and a layer of Air Suspension polymer just above the base foam layer. Serta rates the firmness of this mattress as a 5/10 comfort level.

Size & Pricing

The iComfort Blue 100 comes in all standard bed sizes, including California King. This mattress is among the thinnest of the iComfort memory foam mattresses and would likely look a bit out of place without a set of box springs. Unless you’ve got a platform or adjustable platform bed—those accommodate mattresses without box springs quite well. The iComfort Blue 100 is approximately 10″ in thickness and a queen size weighs about 90lbs. The Blue 100  is available directly from Serta, through authorized local dealers, and several online retailers such as Amazon. The Queen size mattress starts out priced at $1,110 though it may be available for less during certain promotions. Certainly not one of the most affordable mattresses we’ve reviewed but well within the range of what we consider reasonable.

Shipping, Warranty & In-Home Trial

The iComfort Blue 100 is a bed-in-box mattress and ships for free via standard ground carriers such as UPS or FedEx. The mattress will arrive in a box approximately 16″ x 16″ x 48″ in size which contains the iComfort in a vacuum-sealed plastic wrapping. This may seem unconventional—even downright strange—but this type of mattress shipping has become the new normal. The iComfort is backed by Serta’s standard Limited 10-Year warranty and features a 100-Night In-Home Trial.

iComfort Memory Foam Mattresses Come in Several Different Models


Serta is one of the biggest names in the mattress industry and has helped pioneer many of the textile technology that we mattress aficionados have come to love. Their products are going to be slightly more expensive than comparative bed-in-a-box brands but offer a better assurance of having construction materials and designs that are well-researched and will last. Serta also offers foundations (a.k.a box springs) designed specifically for the iComfort. These are available in a 9″ thickness or 6″ low profile design. We assume the ship free as well but would urge you to check with your retailer before purchase. We did not have the opportunity to review the foundations. Read through our bed and mattress size guide to better understand which size is best for your bed.

Final Thoughts

The iComfort Blue Max 100 memory foam mattress is a great choice for side sleepers and those under 225-250 pounds, as is common advice for most memory foam mattresses. This is a great choice for anyone looking for a mattress to help lower back pain throughout the night. Many reviews of this mattress specifically mention how much quickly their back pain went away after switching to the iComfort Blue 100. Overall, this is a great mattress and we’d recommend it to just about anyone. You’ll pay ~10% more than you would on a comparable model from other direct-to-consumer sources but get all the benefits and assurance of buying from one of the biggest names in the industry.
