At SleepFoundation.org, we conduct extensive first-person experience tests on all but a select few products. This hands-on approach allows us to provide accurate, data-driven recommendations for mattresses, pillows, sheets, and other sleep essentials.
Guidelines for our testing methodology are as follows:
Every member of our team brings years of industry experience and knowledge to our hands-on evaluations. In addition to testing products, we’ve spoken to sleep experts and toured manufacturing sites.
Our testers fall into different categories based on body type, sleep position, and personal preferences. This level of diversity helps to ensure our product ratings are holistic and inclusive of all sleepers.
Each type of sleep product is tested using a unique set of performance criteria. We also assign ratings based on feedback from testers who fall into specific categories based on weight and sleep position (i.e. side sleepers who weigh 130 to 230 pounds).
We do not personally test CPAP equipment, anti-snoring mouthguards, supplements, and other medical devices that require a doctor's prescription. Rather than using specific rating criteria, we rely on our team's extensive knowledge of sleep products and medical industry standards to pair each reader with the right devices. These evaluations are also based on material and design quality, features, and other noteworthy product attributes.
The Sleepyhead Mattress is an all-foam model engineered for close conforming and temperature regulation. Memory foam infused with gel and copper is designed to reduce heat and microbial buildup while hugging the sleeper closely to ease pressure.

Founded in 2016, Sleepyhead is known primarily for producing mattress toppers with college students in mind. Those models include the Sleepyhead Gel Mattress Topper and the Sleepyhead Super Topper. As the popularity of the brand’s mattress toppers has remained steady, Sleepyhead added a mattress to its product line in 2026.
The Sleepyhead Mattress, also known as the Sleepyhead First Edition Mattress, is a medium (5) all-foam model that incorporates materials designed to regulate temperatures and relieve pressure. While Sleepyhead products traditionally target college students, the Sleepyhead Mattress comes in most standard mattress sizes and is appropriate for a wide range of sleepers.
During our in-house tests, we assessed the mattress performance and who this model may be best for. We’ll share those results along with construction, sizing, and policy information to help you decide if the Sleepyhead Mattress is the model you’re looking for.

“For a mattress with exceptional pressure relief, I was surprised that the Sleepyhead didn’t heat up more. Close hugging often traps body warmth, but I stayed at a comfortable temperature.”

Side Sleepers
The Sleepyhead Mattress is well suited to many side sleepers. Its top layer of memory foam provides significant contouring, limiting pressure buildup by spreading out the sleeper’s weight more evenly. Since the mattress has a medium (5) feel, most sleepers can sink in deeply enough to notice the material molding to their shape.
In our testing, the Sleepyhead Mattress was most popular with our side sleepers under 130 pounds because it was plush enough for contouring without letting them sink in too far. Many team members weighing 130 pounds or more also felt comfortable sleeping on their sides, but the surface was softer than some would prefer.
Back Sleepers
Most back sleepers under 130 pounds are likely to get the support and conforming they need from the Sleepyhead Mattress’ medium (5) surface. By adjusting to the body’s natural curves, the bed may make it easier for some who prefer this position to maintain good posture overnight.
However, the opinions of our back-sleeping testers weighing at least 130 pounds were more mixed, with some reporting that their hips sank in deeply enough to cause their spine to curve out of its neutral position.
Stomach Sleepers
As a medium (5) model, the Sleepyhead Mattress may feel comfortably plush for stomach sleepers, but many people who use this position would benefit from more support.
Among our stomach-sleeping team members, the Sleepyhead Mattress was the closest match for those under 130 pounds. Many in this group found the surface comfortable, though some who carry more of their weight around their midsections noticed mild discomfort in their lower backs. Those over 130 pounds found it more challenging to maintain an even sleeping posture because their midsections tended to sink more deeply into the surface.
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
Motion Isolation
9
/ 10
“The memory foam really dampened the surface vibrations. I barely felt any movement transfer across the bed to my side.” – Logan
Motion isolation is one of the Sleepyhead Mattress’ strong suits. Since the memory foam compresses directly under the sleeper rather than spreading movement across the surface, very little motion transfers when a sleeper changes positions or gets in and out of bed.
When we dropped a kettlebell on the bed during testing, our vibration sensor picked up minimal motion across the surface. Team members also said they were not disturbed by testing partners moving around on the opposite side of the bed.
For sleepers who are easily awakened by their partner’s movements, the Sleepyhead may be a top contender.
Pressure Relief
9.5
/ 10
“As a brand known primarily for its mattress toppers, I had high expectations for the Sleepyhead’s pressure relief, and it didn’t disappoint.” – Jeremy
The Sleepyhead Mattress stands out for its pressure relief. Its medium (5) feel lets you sink into the mattress and enjoy close cradling. The memory foam comfort layer hugs closely to the sleeper’s body, so pressure is less likely to build up around the widest or heaviest areas like the midsection and hips. Two additional layers of foam separate the top comfort layer from the denser core, so sleepers are unlikely to press directly against it.
For the majority of our team members, the deep contouring meant a pressure-free testing process. We also mapped pressure using a specialized pad, which showed few — if any — hot spots.
Temperature Control
8
/ 10
“Heat didn’t build up a lot on the mattress. I wouldn’t say it felt cool, but it also didn’t feel too warm. Given how closely the mattress conformed, I’d call that a win.” – Mary
Compared to other medium (5) models with memory foam comfort layers, the Sleepyhead Mattress regulates temperature relatively well. Several components are built for the task. The mattress cover is designed for breathability, while copper and gel infusions in the top layer are intended to transfer heat away from the sleeper’s body. The second foam layer is also engineered for breathability to help heat escape.
Our temperature readings showed mild heat retention, though our testers noted that it was not remarkable enough to impact their overall comfort.
This level of temperature control may make the Sleepyhead Mattress a good option for sleepers who tend to overheat but still want the close hug of memory foam.
Edge Support
6
/ 10
“The edge felt moderately secure to me. I didn’t worry I’d roll off, though I felt more stable a bit farther in.” – Logan
Medium (5) all-foam models aren’t known for their edge support, and the Sleepyhead Mattress follows suit. Since it’s on the plusher end of the mattress firmness range, the foam compresses noticeably when a sleeper sits or lies along the perimeter. To some individuals, this can feel like the mattress is sinking out from under them, limiting the usable space, and forcing them toward the middle of the bed.
While most of our testers reported they could use the full mattress surface, many noticed that the edge felt somewhat unstable. For sleepers over 230 pounds, this trait was more challenging since they sank in more deeply.
Ease of Movement
6.5
/ 10
“Changing positions wasn’t overly difficult. At the same time, the Sleepyhead Mattress molds closely to the body and isn’t very responsive, so it also didn’t actively facilitate movement like some models.” – Jeremy
The Sleepyhead Mattress’ close hug makes the surface less conducive to movement than some models, particularly those with coil cores. The memory foam molds to the body and doesn’t instantly return to its original shape when the sleeper moves, leaving a momentary impression to get out of when changing positions.
In our testing, team members moved freely across the surface and changed positions mostly unencumbered. While it took some effort, they didn’t report any interference with their sleep or comfort. However, for sleepers with mobility issues, especially those who frequently switch positions overnight, movement may be more difficult.
Durability
7
/ 10
Most all-foam mattresses last 6 to 7 years, and the Sleepyhead Mattress should enjoy a similar life expectancy.
Foam naturally deteriorates over time, even with routine care and careful use. However, the Sleepyhead Mattress’ multilayer design could help spread out that wear and tear so it is less noticeable on the surface.
Use the mattress as directed and follow care instructions to help extend your Sleepyhead Mattress’ lifespan.
Sleepyhead Mattress Review Breakdown
The Sleepyhead Mattress is an 11-inch all-foam model with a medium (5) feel.
Its cover uses polyester-based CoolTech 2.0 fabric engineered for breathability. The mattress cover can also be removed and washed for easy cleaning.

The top layer of the mattress consists of memory foam that contours closely to limit pressure points. Meanwhile, copper and gel infusions in the material are built for temperature control. This layer is also intended to resist microbes, dust mites, and odors.
A secondary layer of foam underneath deepens the cradling, and it’s also engineered for airflow. Next, a high-density polyfoam layer helps redistribute weight while reducing the likelihood that the sleeper will sink in against the firmer core.
At the base of the mattress sits a supportive polyfoam core that acts as a stable foundation for the layers above.
