Our Serta Perfect Sleeper Innerspring Review, Summarized
The Serta Perfect Sleeper Cascade Range delivers a traditional innerspring feel and comes in several firmness options, including select pillow-top models. We found that the Medium versionโs firm feel and consistent support made it an exceptional fit for sleepers with larger bodies and couples. However, it may be too firm for lightweight sleepers and side sleepers with joint pain, who typically need more cushioning around sensitive areas like the shoulders and hips.
The Serta Perfect Sleeper Cascade Range has a classic innerspring mattress feel. The Cascade Range comes in multiple firmness options, and some of those options come with a pillow top. The 14-inch Medium model impressed our team in every testing category, scoring at least 4 out of 5 in all of them (aside from sleep trial and warranty)
What our tester says:
โIn my opinion, it doesnโt get much better than this at this price range. The Cascade Range impressed us with its superior cooling, motion isolation, and durable support system that should maintain its shape and prevent sagging for many years to come.โ -Kenny Timper, senior staff writer and certified sleep science coachOur Review Process
At Sleepopolis, our team of certified sleep science coaches personally tests each mattress. We start by unboxing the mattress to figure out how difficult (or easy) it is to get the mattress from the box to the bed. Then, we spend time lying on the bed in different positions, taking time to assess it on our back, stomach, and side. Next, we perform our Sleepopolis tests, using specialized tools to measure qualities like motion transfer, bounce, and pressure relief. Our last step is to open up the mattress and take a look at each layer. These steps allow us to give our final verdict on each mattress.

Serta Perfect Sleeper Cascade Range Value
The Serta Perfect Sleeper Cascade Range Medium mattress is $999 before any discounts. In my opinion, it doesnโt get much better than this at this price range. The Cascade Range scored a 4 out of 5 or higher across the board and has a durable support system that should maintain its shape and prevent sagging for many years to come.
The only downside on this front is the sleep trial and warranty. Serta offers a 100-day sleep trial and 10-year limited warranty, and while this isnโt awful by any stretch, we would have liked to see more competitive policies from the mattress giant.
What Is the Serta Perfect Sleeper Cascade Range Made Of?
The Serta Perfect Sleeper Cascade Range Medium is a 14-inch mattress with dense pocketed coils for even weight distribution and stability. While technically a hybrid model (as it combines innerspring coils and foam), it has more of a traditional innerspring feel, hence why Serta advertises it as such.
My first impression of this bed was that it is a thick mattress. The foam tufts on the cover layer are super noticeable and soft, and it is definitely on the firmer side. When I cut it open, I saw a series of top foam layers and a thick bottom foam layer. The bottom foam layer has springs inside it.
Cover โ The cover layer of this mattress is soft, tufted, and pillowy. It adds a layer of plushness to an otherwise very firm mattress. When lying on this mattress with no bedding, these tufts are very noticeable against your back. While I didnโt find them uncomfortable, I could see them being distracting to some sleepers.
Comfort Layer โ The two comfort layers contain quilted foam that conforms to your body. Based on my experience, lightweight sleepers and most average-weight sleepers might not notice much contouring around their joints and lower back, but heavier sleepers may sink more into its foams and reap the benefits of these conforming foam layers.
Support Layer โ The next layer, and the bulk of the mattress, is made of dense, zoned coils that provide adequate support to every part of your body. These coils are encased in a thick block of foam for added stability.
Serta Perfect Sleeper Innerspring (Cascade Range) Mattress Firmness
The way a mattress feels, including firmness, is different for everyone and depends on a host of personal qualities. Preferred sleeping and body weight play a role in how firm a mattress feels to a person, which is why we invited testers with various body types and preferences to lie on it and provide their feedback. Every tester rated the firmness level of the Cascade Range Medium mattress according to our mattress firmness guide, and we averaged their individual scores to determine an overall firmness rating.
While testing the Serta Perfect Sleeper Cascade Range, my fellow mattress testers and I agreed it was firmer than the industry standard of medium-firm (6.5 out of 10). We gave it a firmness rating of 7.5 out of 10.
This firmness was most noticeable for me in the side-sleeping position. While the soft tufts on the surface felt nice on my shoulders and hips, there wasnโt much contouring around those areas. If youโre a side sleeper who prefers a firmer-than-average sleep surface, then this might work for you. If you have sore joints and you are seeking pressure relief, you might need a softer or more memory-foam-forward mattress.
Serta Perfect Sleeper Innerspring Mattress Performance
During testing, we use a thorough review methodology to evaluate performance in key categories. This process helps us prioritize the features that matter most to sleepers. See our in-depth test results for the Perfect Sleeper Cascade Range below, where we evaluate factors such as cooling, edge support, pressure relief, and more.
Pressure Relief Performance
Your mattress should provide enough cushioning and contouring to prevent tension from building up in pressure-prone areas. Common pressure points for many sleepers include the shoulders, hips, and lower back. If your mattress is unable to relieve pressure night after night, it could lead to chronic pain later on.
When testing pressure relief, my team and I use a pressure-mapping mat to measure how the mattress distributes weight in both the back- and side-sleeping positions. The image it generates is a color-coded map with blue and green zones indicating minimal pressure and yellow and red areas showing high-pressure buildup. These images help us predict how effectively a mattress will reduce tension for different body types and sleep positions.
The graphic also shows the average PSI (pressure per square inch) in both positions. The average PSI measurements for side sleeping and back sleeping are 14.58 and 12.43, respectively. Any number lower than those generally points to solid pressure relief.
While testing the Perfect Sleeper Cascade Range, the mat calculated a PSI of 10.95 for side-sleeping and 8.6 for back-sleeping for our average-weight tester. Lightweight tester Riley Otis also saw impressive results, with a PSI of 11.35 for side-sleeping and 8.19 for back-sleeping. These results are impressive, especially when considering the firm feel of the Cascade Range mattress.
Mattresses typically feel firmer to lightweight sleepers because they donโt sink in as much as they do for other sleepers. This lack of sinkage typically means less cushioning and more pressure buildup.
However, as impressive as these results are, I am still hesitant to recommend this mattress to side sleepers with existing shoulder or hip pain. I would still steer these sleepers toward a softer mattress with deeper contouring to ensure those sensitive areas get the relief they need.
Motion Isolation
We test motion transfer on every mattress to see how well it traps movement on one side of the bed and prevents it from spreading across the surface. A mattress with low motion transfer, or excellent motion isolation, is a must-have for couples with a restless partner. During testing, we rated the Serta Perfect Sleeper Cascade Range 4 out of 5 in this category.
Ripple test: The ripple test involves one of our in-house testers lying next to a bin of water on the mattress and moving around beside it to see if the liquid ripples, splashes, or spills onto the mattress.
I was pleasantly surprised during this test. In my experience, responsive innerspring mattresses typically underperform in this category because they are so bouncy. While the water rippled somewhat, it was a far cry from the violent sloshing I was expecting.
Motion transfer test: The partner test assesses how well a mattress would perform for couples. For this test, two testers lie beside each other on the bed. One tester wears a blindfold and lies still on their side while their colleague rolls around and gets in and out of bed on the other. The blindfolded tester raises their hand or gives a thumbs up whenever they detect movement on their side of the bed.
During this test, I was expecting to feel my testing partner, Sosha Lewisโs, every movement, but it did surprisingly well. I couldnโt really detect her getting in and out of bed, but I raised my hand three times while she was changing sleeping positions. It was noticeable but not particularly disruptive. If someone is a light sleeper, it might disturb them, but most people should sleep through it just fine.
Responsiveness
Responsiveness is how quickly a mattress returns to its original form after adding and removing weight or changing positions on it. This feature is essential for ease of movement for combination sleepers, or those who frequently change sleeping positions to get comfortable.
Generally speaking, innerspring and hybrid mattresses are more responsive than memory foam mattresses, thanks to the springy individually wrapped coils in their construction. This rule certainly proved to be true for the Cascade Range, which I found mostly easy to move around on.
Switch test: During the switch test, I lie on the bed and note how difficult it is to switch between different sleeping positions. When lying on the Perfect Sleeper Cascade Range, I found it was bouncy, responsive, and easy to switch positions on, but the tufts are so high that they could be a bit of a nuisance. That said, the tufts on the cover layer should be less noticeable once you put your sheets and covers on the mattress.
Sinkage test: Our sinkage test involves placing a 53-pound kettlebell on the mattress and using a ruler to measure the sinkage. During this test, I measured 3.5 inches of sinkage on the Serta mattress, which placed it in the moderate sinkage category. For reference, light sinkage is up to 2.5 inches, moderate sinkage ranges from 2.6 to 4 inches, and deep sinkage is 4.1 inches or more.
Most of that sinkage occurred in the plush top layer, so I think some lightweight sleepers will experience some gentle body contouring in areas like their shoulders, hips, and lower backs. However, they will still definitely feel more โon topโ of the mattress than โinโ it.
Meanwhile, average-weight sleepers and those with larger bodies may experience a better balance between the soft cushioning up top and firm support beneath.
Bounce test: During the bounce test, a mattress tester climbs a ladder 6 feet above the mattress and drops a 25-pound steel ball. A yardstick on the wall helps us measure how high the ball bounces and determine how responsive the mattress is.
Unsurprisingly, the ball bounced 35 inches on this innerspring Serta mattress. These results put it in our โhigh bounceโ category and align with what I found during the switch test. The Cascade Range bounce height beat our average of 15.8 inches by nearly 20 inches.
For reference, low bounce is anything under 8 inches, moderate bounce ranges from 8 to 12 inches, and high bounce is above 12 inches.
Cooling
If you tend to wake up hot or covered in sweat, cooling features (like phase change material, gel memory foam, and cooling fibers) can go a long way in saving your sleep. Innerspring mattresses are often a solid choice for hot sleepers, as the coil layers naturally facilitate airflow and temperature regulation.
It should come as no surprise, then, that the Cascade Range mattress earned an above-average rating of 4 out of 5 in this category.
Thermal gun test: For this test, I used a thermal gun to measure the surface temperature before and after I lay on it for five minutes. After 5 minutes, I saw a 6.8-degree increase, which is excellent, especially considering that the plush cover layer is likely more susceptible to heat.
Feel test: After completing the thermal gun test, I felt the mattress beneath me with my hands to see if it retained heat. While the tufted layer below me didnโt feel particularly cool to the touch, it wasnโt incredibly hot either. Overall, I was very impressed with the Cascade Rangeโs performance.
Edge Support
Edge support is how well the mattressโs corners, sides, and overall perimeter maintain their shape when someone is lying or sitting on it. Robust edge support is essential for couples, larger sleepers, and individuals with mobility concerns. A mattress with supportive edges allows you to rest on the sides without feeling unsteady. It also provides a safe surface to press down on when standing up in the morning.
I gave the Serta Perfect Sleeper Cascade Range a perfect 5-star score in this category.
Tape measure test: We stack weights directly onto the edge of the mattress and measure how much the bed sinks under each load. We repeat this process three times with increasing weight loads: 99 pounds, 154 pounds, and 198 pounds. The testers then record the level of sinkage under each stack of weight using a tape measure.
This tape measure test evaluates how well the mattress supports weight along its perimeter. The 99-pound stack represents lightweight sleepers, the 154-pound stack represents average-weight sleepers, and the 198-pound stack represents heavyweight sleepers. The Cascade Range mattress sank by 0.5, 1.5, and 2 inches in each of these categories, respectively.
Based on these results, most sleepers would probably feel as though they were resting on a plank of wood, were it not for the cushioned layer up top. From corner to corner, this is a supportive mattress that sleepers should feel secure on, even if they gravitate toward the very edge of the bed.
Seated test: For the seated test, I sat along the corners and sides of the Cascade Range mattress. I sat down and stood up multiple times to see how easy it was to get in and out of bed. I also wanted to see how secure I felt while sitting on the bed.
Mattresses typically sink more during this test because youโre concentrating more weight into a smaller area (your bottom). However, the seated edge support on this mattress is really impressive. It barely sank in at all when sitting on it, and I was able to lift myself out of bed without using my hands. Really easy to get in and out of bed; I would have no problem recommending this mattress to folks with mobility concerns.
Full-body test: The last edge support test involves lying on the perimeter of the mattress to see if I can comfortably rest without fear of falling off the bed. My experience lying down on the edge of the mattress was not dissimilar to sitting on it.
I didnโt feel unsteady or like I was going to fall off while lying on the perimeter of this mattress. But again, the tufts might be distracting for some people. I didnโt feel uncomfortable, but that is something to keep in mind.
Serta Perfect Sleeper Innerspring Mattress Performance for Couples
In many ways, the Serta Perfect Sleeper Cascade Range mattress is a dream come true for couples. It has strong motion isolation to prevent movement from disturbing your partner, cooling to facilitate cuddling without overheating, and supportive edges to give you a private space to roll over to when you get in a spat.
Other Performance Factors to Consider
Before you splurge on this Serta mattress, consider the following factors that many overlook.
Sex
To determine if a mattress is good for sex, we average responsiveness, cooling, and edge support. Responsiveness is arguably the most important factor to consider here, as a mattress should be easy to move around on during intimate moments. The Cascade Range earned above-average scores in each of these categories for a total sex score of 4.3 out of 5.
Noise
I did not notice any noise from this mattress during testing. There was maybe a slight clang from the bed frame, but I donโt think that had anything to do with the mattress.
Durability
According to Dr. Raj Dasgupta, one of our medical advisors and sleep experts, edge support is one of the most important factors to consider when choosing a mattress for its durability. According to him, a mattress with reinforced edges and a strong support core is less likely to sag over time. In other words, the 5-star edge support and supportive, firmer-than-average construction suggest that the Cascade Range is in it for the long haul.
Plus, Serta beds come with a 100-night sleep trial and a 10-year limited warranty, so you can sleep a little more peacefully knowing that defects and premature sagging are covered.

Serta Perfect Sleeper Innerspring Sleeping Position and Body Weight
Your body weight significantly impacts how a mattress feels, which is why our in-house team obtains feedback from mattress testers across a range of body types. In general, a mattress will feel softer to sleepers with bigger bodies, as they are more likely to sink further into the layers.
โSleepers who weigh less than 130 pounds are likely to find a mattress more firm because they will not get as much contouring,โ explains Dr. Dasgupta. โHowever, a firmer mattress might sink deeper for those who weigh 230 pounds or more, which would make it feel softer.โ
Before we dive into our recommendations, though, we want to recognize that people come in all shapes and sizes, and people of every size deserve a mattress that works for their body type. We use the weight categories light, average, and heavy to more easily categorize sleepers based on how mattresses will perform for their body type, as most mattresses are designed for the group we call โaverageโ (130 to 230 pounds).
As a general takeaway, lighter sleepers donโt require as much support as average-weight sleepers, and mattresses will tend to feel firmer to them. On the other hand, heavy sleepers tend to need more support than average-weight sleepers and sink into the mattress more. As far as sleeping positions go, side sleepers likely need a softer mattress while stomach sleepers usually need a firmer, more supportive one. Back sleepers are usually somewhere in the middle.
Is the Serta Perfect Sleeper Cascade Range a Good Mattress for Light Sleepers (Under 130 pounds)?
- Light Back Sleepers โ Back sleepers in this weight category who prefer a firmer sleep surface should feel comfortable on the Cascade Range. These sleepers will likely feel more โon topโ of the bed and get enough lower-body support to keep their spines in neutral alignment.
- Light Side Sleepers โ I would not recommend this mattress for lightweight side sleepers, especially those with joint pain. These sleepers will not get the contouring they need to relieve pressure meaningfully on this bed.
- Light Stomach Sleepers โ The Cascade Range is an excellent choice for lightweight stomach sleepers. This mattress should keep their body in a straight line, which is the biggest challenge stomach sleepers face across the board.
Is the Serta Perfect Sleeper Cascade Range a Good Mattress for Average-Weight Sleepers (130โ230 pounds)?
- Average-Weight Back Sleepers โ Average-weight back sleepers who prefer sleeping on a firmer mattress should love the Cascade Range. The tufted cover layer should provide some cushioning to fill the lower lumbar area, but these sleepers will likely feel the support more than anything.
- Average-Weight Side Sleepers โ I think this mattress is a touch too firm for side sleepers in this category, especially if they have preexisting joint pain. That said, it could work for some side sleepers who prefer a firmer mattress.
- Average-Weight Stomach Sleepers โ Like back sleepers in this weight category, these sleepers will find enough lower lumbar support to maintain healthy spinal alignment.
Is the Serta Perfect Sleeper Cascade Range a Good Mattress for Heavy Sleepers (over 230 pounds)?
- Heavy Back Sleepers โ Heavy back sleepers will sink in more than light and average-weight sleepers on this mattress. Still, they should find the support they need thanks to the Cascade Rangeโs dense layer of innerspring coils.
- Heavy Side Sleepers โ These sleepers should get the perfect balance of support and contouring on this mattress.
- Heavy Stomach Sleepers โ Stomach sleepers in this weight category might sink further into the Cascade Range than other sleepers, but they should still feel supported and comfortable on this mattress.

Serta Perfect Sleeper Cascade Range vs DreamCloud
The DreamCloud is a high-scoring hybrid mattress that earned a firmness rating of 6.5 out of 10 during our testing. Like the Cascade Range, it has a supportive layer of coils and a soft, tufted cover layer for added comfort.
- Price: At full price, the DreamCloud is $1,892 for a queen-size mattress, which is nearly $900 more than the Cascade Range.
- Sleeping position: Both mattresses are solid options for back sleepers. However, the DreamCloud is more gentle on the joints, making it more comfortable for side sleeping. The Cascade Range has the edge when it comes to stomach sleeping, thanks to its ultra-supportive feel.
- Cooling: The crisp cover layer of the DreamCloud gives it a slight edge in this category. We gave the DreamCloud mattress an impressive 4.5 out of 5 during testing.
- Body weight: The DreamCloud and Serta are both good options for average-weight sleepers. However, the DreamCloudโs softer surface is better for lighter bodies.

- Price: The Kendall Medium is more expensive than the Cascade Range at $1,899 for a queen-sized mattress.
- Sleeping position: Both mattresses are better suited for back and stomach-sleeping. Side sleepers will need something much softer than these models.
- Cooling: Both models performed similarly on our cooling tests, with each mattress earning a 4 out of 5 in this category.
- Body weight: Average-weight sleepers who prefer a firmer sleep surface and sleepers with bigger bodies should feel very comfortable on either bed. Lightweight sleepers will likely find both mattresses too firm for their liking.
