The Best iComfort Mattresses, Reviewed
Serta iComfort Aveda 12" Medium Queen Memory Foam Mattress
What We Like
- 5 ZoneResponse spinal alignment design
- EverCool Fuze Gel Memory Foam cooling
- Graphite-infused foam redistributes heat
- Perfect Conform Memory Foam pressure relief
Trade-offs
- 95 pounds makes solo setup difficult
- No latex option for those who prefer bounce
A 12-inch medium memory foam mattress with five distinct support zones aims to keep your spine aligned whether you sleep on your side, back, or stomach. The EverCool Fuze Gel Memory Foam paired with graphite-infused layers is designed to pull heat away from your body, which can help reduce waking up sweaty. This mattress offers balanced support that does not favor one sleep position and includes cooling technology built into the foam.
At 95 pounds, this queen mattress is heavy enough that you will want a second pair of hands for unboxing and positioning, especially if your bedroom is upstairs. The Serta iComfortPro Granby 11.5″ Extra Firm King uses latex foam, while the Aveda’s medium feel and gel memory foam suit sleepers who want balanced comfort with cooling features. Combination sleepers get the benefit of a 5 ZoneResponse design that supports full-body spinal alignment, along with graphite-infused memory foam that redistributes heat away from your body.
Serta iComfortPro Granby 11.5" Extra Firm King Latex Foam Mattress
What We Like
- Extra firm feel for stomach/back sleepers
- 2" naturally-derived latex foam layer
- Five ZoneResponse spinal alignment design
- CoolFeel Pro cooling fabric and breathability
Trade-offs
- At 106.5 lb, rotating or moving is difficult
- Not suited for side sleepers who prefer a plush cradle
The five-zone response design in this mattress targets full-body spinal alignment while the 2-inch layer of naturally-derived latex foam provides a responsive, long-lasting feel. That extra firm support is exactly what stomach and back sleepers need to keep their spine neutral through the night, without sinking into pressure points. The CoolFeel Pro system pairs a cool-to-the-touch fabric with latex’s natural breathability, so you’re less likely to wake up overheated even on warm nights. If you prefer a bed that holds you up rather than wraps around you, this one delivers that unyielding surface with thoughtful zoning for proper posture.
The trade-off is weight: at 106.5 pounds, this king mattress is heavy enough that rotating or moving it for cleaning is a two-person job. Just be sure you’re ready for the firmness and the heft before committing.

How We Evaluated iComfort Mattresses
Our evaluation of these iComfort models is based on manufacturer specifications, material composition data, and patterns in owner feedback from across the bedding industry. We analyzed construction details like foam density, gel infusion, and zoned support systems to understand how each mattress performs.
The four criteria that mattered most were cooling technology, support design, firmness suitability, and practical ownership factors. IComfort mattresses use a range of cooling methods, from gel memory foam to graphite infusions and cooling fabrics. We weighed how each layer contributes to temperature regulation. We also evaluated the Five ZoneResponse spinal alignment design present in both models, noting how it affects pressure relief and edge support.
An honest limit of a research-led evaluation is that we cannot report on long-term durability or feel changes over years of use. We relied on owner reports about sagging, edge breakdown, and cooling effectiveness to supplement the spec sheets. For the latest Serta mattress reviews and updates, we recommend checking recent owner experiences.
What To Look For In iComfort Mattresses
Choosing an iComfort mattress comes down to matching its cooling and support layers to your sleep position and temperature preferences. Here are the key factors to consider.
Focus on the cooling layer type (gel, graphite, or phase-change), the firmness profile, and the zoned support system. Your weight and sleep position will determine whether a medium or extra firm feel is right.
Cooling Technology
IComfort mattresses use several cooling approaches, but the most common are gel-infused memory foam and graphite-infused foam. The best cooling memory foam models typically combine both, as graphite conducts heat away from the body while gel absorbs and dissipates it. Look for the EverCool Fuze Gel Memory Foam layer in the Aveda model, which is designed to reduce the heat retention common in traditional memory foam. The Granby uses CoolFeel Pro fabric and breathable latex to promote airflow.
Support and Spinal Alignment
The Five ZoneResponse system is a key feature across iComfort models. It uses targeted support zones to keep your spine aligned while reducing pressure on shoulders and hips. The best firm mattresses in the iComfort line, like the Granby, use an extra firm latex layer to prevent sinking for stomach and back sleepers. The Aveda’s medium feel uses Perfect Conform Memory Foam for contouring without sagging.
Firmness and Sleep Position
- Side sleepers generally need a medium or plush feel for pressure relief at the shoulders and hips.
- Stomach and back sleepers often prefer firm or extra firm support to prevent the hips from sinking out of alignment.
- Couples with different preferences may need to consider a compromise firmness or look at mattresses for couples with zoned or split options.
- Heavier individuals may find the extra firm Granby provides better support than the medium Aveda.
For most people, the medium-firm Aveda is the safer choice unless you know you need an extra firm surface for stomach sleeping.

Frequently Asked Questions
What is the difference between the Serta iComfort Aveda and Granby?
The Aveda is a 12-inch medium-firm memory foam mattress with EverCool Fuze Gel and graphite-infused foam for cooling. The Granby is an 11.5-inch extra firm latex foam mattress with CoolFeel Pro fabric and a naturally-derived latex layer for more responsiveness and breathability. The Aveda suits most sleepers; the Granby is for those needing firm support.
Which iComfort mattress is best for side sleepers?
The Serta iComfort Aveda 12″ Medium is the better choice for side sleepers. Its medium feel and Perfect Conform Memory Foam provide pressure relief at the shoulders and hips, which side sleepers need to maintain spinal alignment. The Granby’s extra firm feel is generally too hard for side sleeping.
Do iComfort mattresses sleep cool?
Yes, iComfort mattresses are designed to sleep cooler than standard memory foam. The Aveda uses EverCool Fuze Gel Memory Foam and graphite-infused foam to pull heat away from the body. The Granby uses CoolFeel Pro fabric and latex foam, which is naturally more breathable than memory foam. Both models reduce the heat retention common in older foam mattresses.
How heavy is an iComfort mattress, and can I move it alone?
The Serta iComfort Aveda weighs about 95 pounds for a queen size, and the Granby weighs around 106.5 pounds for a king. Both are very heavy and difficult for one person to move or rotate safely. You should plan to have at least two people for setup, and consider using a mattress bag for protection during moves.
Is the iComfort Granby good for back sleepers?
Yes, the Serta iComfortPro Granby 11.5″ Extra Firm is specifically designed for stomach and back sleepers. Its extra firm latex layer prevents the hips from sinking, which helps maintain neutral spinal alignment. The Five ZoneResponse system adds targeted support to the lumbar region, making it a strong choice for back sleepers who prefer a firm surface.
The Bottom Line
For most shoppers, the Serta iComfort Aveda 12″ Medium Queen Memory Foam Mattress is the best overall choice. It delivers the cooling and pressure relief that memory foam buyers want, with a medium feel that works for side, back, and combination sleepers. Its spinal alignment design and gel-graphite cooling make it a versatile option for anyone who sleeps warm or needs pressure relief.
If you are a stomach or back sleeper who knows you need an extra firm surface, the Serta iComfortPro Granby 11.5″ Extra Firm King Latex Foam Mattress is worth paying more for. Its latex layer adds responsiveness and breathability that standard foam cannot match, and the firm support keeps your spine aligned all night.
The single most important factor is matching the firmness to your sleep position. Side sleepers should stick with the medium Aveda; stomach sleepers should consider the extra firm Granby. Everything else, cooling, weight, and materials, matters less than getting the right support level for your body.
