The Serta iComfort Standard is an all-foam mattress model that comes in three firmness levels and profile thicknesses. Side sleepers in particular should enjoy the cradling, pressure-relieving quality of this mattress.
- Three firmness options to accommodate different sleeper types
- Memory foam excels at relieving pressure and absorbing motion
- Free White Glove delivery and old mattress removal for online orders
- Stomach sleepers over 230 pounds may prefer a firmer mattress
- The Plush model sleeps warmer than the other two designs
Serta has a long history of producing high-quality mattresses and bedding. Since merging with Simmons in 2016, the brand has introduced a wide selection of premium mattresses, including the iComfort all-foam mattress line. The iComfort Standard is the entry-level model in this collection. Other Serta mattress offerings include the Perfect Sleeper X, Perfect Sleeper X Series Two collections, and Serta Arctic.
Our team evaluated all three firmness levels of the Serta iComfort Mattress in our Seattle Test Lab, using high-tech tools to see how well each bed performs in terms of temperature regulation, motion isolation, and pressure relief. The results of our hands-on tests can help you decide whether the Serta iComfort will work well for you.

TEST LAB RATINGS
How the Serta iComfort Scored
Motion Isolation9.5/10
The Serta iComfort Standard is a standout when it comes to motion isolation. When a person sleeping on one side of the bed rolls over or gets in or out of bed, their movement is unlikely to disturb a bed partner sleeping on the other side of the bed.
Soft memory foam comfort layers absorb vibrations, and are the reason this mattress isolates motion so well, The Firm model contains firmer foam, so there is more motion transfer, However, even the Firm model is above-average at motion isolation.
Logan Foley, Executive Product Director: Most sleepers won’t be disturbed by movement traveling across the bed’s surface on the Serta iComfort Standard, especially the Plush and Medium models.
Pressure Relief9.5/10
We use a body mapping tool to visualize where and how much pressure builds up beneath a person lying on a bed. We found that all three models of the iComfort Standard are above-average when it comes to distributing body weight evenly over the bed’s surface and reducing pressure buildup beneath heavier areas of the body.
Higher pressure relief scores generally translate into less pain and discomfort for sleepers. The softer iComfort Standard models excelled more at relieving pressure, but people should still choose the model for them based on their sleep position and body weight, rather than by pressure relief score.
Mary Fenton, Head of Product Content: In all firmness options, this mattress excels at relieving pressure. When people choose the right model for them, they shouldn’t experience strain from pressure buildup.
Temperature Control7.0/10
Memory foam is a mattress material prone to absorbing body heat. However, Serta has taken efforts to offset this tendency in the iComfort by incorporating a cooling cover and graphite-infused memory foam.
Whether the iComfort Standard will feel too hot for you depends on your normal sleep temperature. Those who sleep relatively cool shouldn’t have issues with any of the three models, but sleepers who run hot may only find the Firm model cool enough.
Brad Nehring, Product Testing Manager: I wasn’t too hot when sleeping on the Medium iComfort Standard, but people who become overheated easily might want to opt for the Firm model or another mattress.
Edge Support6.0/10
Edge support is an important factor for people who need to use the perimeter of their mattress as leverage when getting in and out of bed. With the iComfort Standard, the Firm model has average edge support and can adequately support most sleepers.
The Plush and Medium models have below-average edge support. While many sleepers won’t notice or feel bothered by this, it may lead to buckling edges for heavier sleepers and feel unstable for those who regularly sit on the edge of the bed.
Brad Nehring, Product Testing Manager: I felt comfortable lying near and sitting on the edge of the Firm iComfort Standard, but the Plush and Medium models folded a little beneath my body weight.
Ease of Movement6.5/10
The deep contouring of soft memory foam can be a double-edged sword. While its “hug” feels comfortable and relieves pressure for many sleepers, the temporary body impressions that form in memory foam can feel like ruts that are hard to get out of when it’s time to move.
The Firm model of the iComfort Standard scored average in terms of ease of movement, and most sleepers won’t have a problem moving on its surface. The Plush and Medium models may provide more resistance, especially to sleepers who already struggle with strength or mobility.
Logan Foley, Executive Product Director: I didn’t have a problem rolling over or getting out of bed, but the Plush model is so soft and conforming that some people may find these movements difficult on its surface.
Durability6.5/10
We expect the Medium and Firm Serta iComfort Standard Mattresses to last an average length of time, which is about 6 or 7 years. The estimated lifespan for the Plush model is a bit shorter. The memory foam comfort layers are most likely to degrade first, which could change the feel of the mattress and the level of comfort it provides.
HANDS-ON TESTING
Testing Team Takeaways
To test the Serta iComfort, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.
Brad Nehring
Product Testing Manager · Back sleeper · 215 lbs.
Back sleeper · 215 lbs.
“As a back sleeper, all of the Serta iComfort Standard models felt comfortable to me, though I felt like the Medium was most effective at keeping my spine aligned.”
Mary Fenton
Head of Product Content · Combination sleeper · 150 lbs.
Combination sleeper · 150 lbs.
“The Firm iComfort Standard is a nearly ideal mattress for me, especially when I’m sleeping on my back or stomach. The Plush and Medium models weren’t as supportive, and they were more difficult to change positions on.”
Logan Foley
Executive Product Director · Side sleeper · 140 lbs.
Side sleeper · 140 lbs.
“I received immense pressure relief while sleeping on the Plush iComfort Standard. I also couldn’t detect any motion whatsoever from my partner on the other side of the bed, which was a plus.”
Who it Fits
Fit by Sleep Position and Body Weight
Sizes, dimensions and weights
Side Sleepers
The iComfort Standard’s highest ratings came from side sleepers. Across all body types, side sleepers will find a good match with at least one of the iComfort’s three firmness levels. Side sleepers up to 230 pounds tend to prefer the Plush and Medium models, while those over 230 pounds should feel more supported on the Firm model.
Zoned support is the primary reason the iComfort works so well for this group. The bed is designed to provide more reinforcement around the midsection, allowing the lower back and hips to sink in gently without compromising spinal alignment. This ensures ample cushioning and extra support where side sleepers need it most.
Back Sleepers
Virtually all back sleepers can find comfort on the Serta iComfort Standard, provided they choose the right firmness level for their weight. The Firm model rates the highest with back sleepers across different body types, particularly those who weigh 130 pounds or more.
Back sleepers under 130 pounds should be satisfied with the Plush and Medium models. Those between 130 and 230 may also find the Medium model comfortable, but they generally prefer the Firm.
Stomach Sleepers
For most stomach sleepers, the Firm model of the Serta iComfort Standard will be the best of the three options. This design can provide the support needed to keep a stomach sleeper’s spine aligned throughout the night. Those under 130 pounds may also be able to find comfort on the Plush and Medium models, but these aren’t adequate for stomach sleepers over 230 pounds.
Some stomach sleepers who weigh more than 230 pounds may find that even the Firm iComfort Standard isn’t ideal for them. These sleepers might want to opt for an even firmer mattress to ensure that their midsection doesn’t sink into the mattress at night, which can create strain in the lower back and neck.
