The Sealy Posturepedic Hybrid is a high-end hybrid mattress. Sealy markets its 'Posturepedic' mattresses as being designed by orthopedic specialists. The 'Hybrid' option is the higher-end mattress in the lineup and uses more foam in its comfort layers. This mattress uses pocket coils in its support layer and polyfoam and memory foam for its comfort layers.
The 'Soft' variant of the mattress has a 'Medium-Plush' firmness rating. This makes it well-suited for average and lighter side sleepers, who may want a plusher mattress to comfortably cushion the shoulder and arm area. Heavier side sleepers and most back and stomach sleepers may want something firmer that provides more support for the hips and lumbar. This mattress is moderately bouncy, which helps make it feel easier to move around in your sleep. The soft memory foam upper comfort layer helps give it moderate sinking and contouring, so you feel cradled but not enveloped or tightly hugged.
Our Verdict
The Sealy Posturepedic Hybrid offers a great sleeping experience. Its medium-plush feel is best-suited for lighter people and some average side sleepers. It's well-suited for sleeping with a partner, since its great motion dissipation means you'll only feel the initial shock of movement, making your restless partner less likely to wake you up. While it uses memory foam for its upper comfort layer, which is a slower-moving material, it's very responsive, so you won't feel stuck in place. It offers fantastic edge support, so you can sleep or sit on the very edge without feeling at risk of slipping off. It also offers very good cooling, so it won't make you feel overheated, although hot sleepers looking for a very cooling mattress won't find it quite cooling enough.
High responsiveness, so you can easily move around.
Fantastic edge support, so you can easily get in and out of bed.
Very good cooling for most sleepers.
Good for light and average side sleepers.
Not firm enough for most back and stomach sleepers.
Heavier side sleepers may want something firmer.
Uses lower-quality foams.
The Sealy Posturepedic Hybrid is very good for cooling. It doesn't feel hot during the first hour of sleep and dissipates heat efficiently over an eight-hour night. If you don't usually have an issue with sleeping hot, it won't make you feel warmer. While it may be adequate for occasional hot sleepers, if cooling is a big priority, you may want to go for something with an even better cooling performance.
Very good cooling for most sleepers.
Not cooling enough for hot sleepers.
The Sealy Posturepedic has a great motion-dissipation performance. You'll only feel movements near the area where they originate, but not much motion travels across the mattress, and it dissipates quickly. You'll feel it in the lumbar area when your partner rolls over, but won't feel the mattress wobbling whenever someone moves, making motion less likely to wake you.
Great motion dissipation, so movement is less likely to wake you.
The Sealy Posturepedic Hybrid has fantastic edge support. It doesn't compress much when you sit or sleep on the side of the bed, making it easier to get in and out of bed and preventing you from feeling like you're sliding out of bed if you sleep near the edge. The outer edges of the mattress's spring layer use firmer coils for reinforcement, which helps give the mattress its strong edge support performance.
Fantastic edge support, so you can easily get in and out of bed.
The Sealy Posturepedic has excellent responsiveness. The mattress recovers its shape quickly after being compressed, which helps make changing sleeping positions easier and helps avoid any feeling of being stuck in place.
High responsiveness, so you can easily move around.
The Sealy Posturepedic Hybrid isn't a durable mattress. Both of its foam layers, including the memory foam upper comfort layer and polyfoam lower comfort layer, are made of low-density, lower-quality foam. These layers are prone to forming permanent indentations or body impressions sooner than higher-quality foams.
Uses lower-quality foams.

Differences Between Sizes And Variants
The Sealy Posturepedic mattress comes in standard sizes: Twin, Twin Long, Full, Queen, King, Split King, California King, and Split California King. Two firmness options, 'Soft' or 'Firm,' are available.
We tested the 'Soft' variant in the Queen size, and our results are only valid for that variant. Here's a picture of our unit's label.
If you have either variant of the Sealy Posturepedic Hybrid, we invite you to share your experience in the comments.
Popular Mattress Comparisons
The Sealy Posturepedic is a medium-plush mattress, making it a good option for lighter and average side sleepers. It's a good option if you sleep with a partner since its great motion dissipation means movement is less likely to wake you. You only sink moderately into it, so if you need a plusher mattress but don't like feeling enveloped, you might prefer it to similar mattresses with higher sinking like the Beautyrest Harmony Lux.
If you're a side sleeper and like a plush-feeling mattress, you may want to consider the Serta Perfect Sleeper Innerspring. It has a similar firmness overall but uses zoned coils, so the spring layer is softer at the head/foot of the mattress and firmer in the lumbar area to support your hips.
If you're looking for a recommendation, check out our picks for the best mattresses.
The Sealy Posturepedic Hybrid and the Serta Perfect Sleeper Innerspring are both hybrid mattresses with a medium-plush feel. The Sealy is a better choice for most people, as it offers better cooling and better motion isolation. The Serta has a more contouring feel, which you might prefer, and has a better edge support performance. The Serta uses one layer of good-quality polyfoam, which is more durable; however, both mattresses also include lower-quality foams.
The Sealy Posturepedic Hybrid and the Beautyrest Black have different strengths. The Sealy performs better in terms of cooling, motion isolation, and edge support. The Beautyrest Black is a more responsive mattress, making it easier to move around in your sleep. It uses mostly good-quality foam, which is more durable. The Beautyrest has a medium firmness, making it better suited for average and heavier side sleepers. In contrast, lighter side sleepers might prefer the plusher feel of the Sealy.
The Sealy Posturepedic Hybrid and DreamCloud Premier Hybrid have different strengths. They both have a medium-plush firmness level and a similar feel, but the Sealy has better edge support. The DreamCloud offers a significantly better motion isolation performance and a marginally better cooling performance.
The Sealy Posturepedic Hybrid performs better than the Sealy Posturepedic Plus Mount Auburn in most respects. The Hybrid is a higher-end model with better cooling, making it better-suited for hot sleepers, and better motion dissipation, so you're less likely to wake up when your partner moves. It features a contouring memory foam layer, yet maintains high responsiveness, making it easy to move around in your sleep. That said, the Mount Auburn offers much better edge support, which is important if you want to maximize the comfortable sleeping surface or make it easier to get in and out of bed.
We've recently started testing mattresses. We use objective data and repeatable testing for key characteristics like firmness, cooling, and motion isolation, to ensure each mattress gets the same treatment. Since we buy all of our mattresses, we can tear them down layer by layer and isolate the mechanical properties of every component: quilted tops, foams, coils, and any special materials. Our approach gives us unprecedented insight into how each product design decision contributes to a mattress's overall performance and feel, and allows us to tailor our results to different body types and sleeping positions.
Test Results
It's a 13"/34.5 cm mattress, so you can use standard fitted sheets.
The Sealy Posturepedic is a 'Medium-Plush' mattress. It's well-suited for light and average side sleepers. Some lighter back and stomach sleepers might find it offers enough support, but heavier people will likely want something firmer.
It has a moderate amount of bounce. It doesn't have a lifeless feel, which makes it easier to move around in your sleep.
This mattress offers a moderate amount of sinking and contouring. Its moderate contouring makes you feel cradled but not hugged. If you want to feel even more like you're sleeping 'on' your mattress versus in it, the lower-end Sealy Posturepedic Plus Mount Auburn has a higher firmness level and less contouring.
It has excellent responsiveness. The mattress recovers its shape quickly after being compressed, which helps avoid a feeling of being stuck in place. If you're looking for a similar option with even better motion isolation, you might be interested in the DreamCloud Classic Hybrid.
The Sealy Posturepedic has great motion isolation. You'll feel motion in the lumbar area when your partner rolls over. However, not much movement is transferred across the mattress, and it dissipates quickly, so you won't feel like the mattress wobbles whenever someone moves.
It has fantastic edge support. The edges are reinforced with pocket coils, and you can sleep on the edge of the mattress without feeling like you're about to fall out of bed. The mattress doesn't compress much when you sit on the edge, which makes it easier to get in and out of bed.
It has very good cooling. It doesn't retain a lot of heat during the first hour of sleep and does a slightly better job of dissipating heat over eight hours. It won't make you feel hot if you don't usually feel overheated. While it may be adequate for occasional hot sleepers, if you're often kept up by heat at night, consider something with a better cooling performance, such as the DreamCloud Premier Hybrid.
The manufacturer doesn't provide the cover materials. When we contacted customer support, they said they couldn't disclose the specific materials because it's proprietary information. They said, "We do treat it with antimicrobial treatment that protects against common allergens, such as dust mite dander and mold, helping the mattress cover stay fresh."
The edges are reinforced with pocket coils, contributing to its fantastic edge support performance.
The upper comfort layer is made of memory foam, which is the mattress's softest layer, so you'll sink into it easily and feel the polyfoam layer below. It's slightly firmer and prevents you from feeling the coil layer below.
Neither the memory foam nor the polyfoam layer is made of foam dense enough to be considered good quality. These lower-quality materials may lead to the mattress sagging or forming permanent body impressions sooner than mattresses that use higher-quality foams.
The upper comfort layer of memory foam is 1.4"/3.5 cm thick, so you may compress it completely and feel the firmer, bouncier polyfoam transition layer. The thin memory foam layer helps the mattress feel responsive overall. Some mattresses with more memory foam, such as the Casper Snow, which uses 3.1" (7.9 cm) of memory foam, are less responsive.
The pocket coil layer is made up of soft 15-gauge coils, and its lower coil density also makes the layer less firm overall. The layer's overall firmness is considered medium.
The mattress's spring layer's medium firmness, combined with its relatively soft foam layers, contributes to its medium-plush overall feel.
The memory foam comfort layer is soft, so you'll sink easily into it. You may also interact with the polyfoam layer below, which is a little firmer but still quite soft. This polyfoam layer is thicker and prevents you from feeling the springs below.
The pocket coil layer has a medium firmness in the lumbar area and a firmer feel at the head/foot of the mattress. Combined with its quite soft foam layers, the coils give the mattress its medium-plush firmness. If you want a mattress with a firmer feel in the lumbar area to provide more support for your hips, you might want to consider a mattress with zoned coils like the Helix Midnight Luxe 2024.
The memory foam upper comfort layer isn't very resilient or bouncy. However, it has more bounce compared with many memory foams, like the foam found in the Tempur-Pedic TEMPUR-Adapt, which contributes to the mattress's moderate bounciness and makes it easier to move around in your sleep compared with less resilient foams. The polyfoam transition layer has a much bouncier feel, so it has more 'push-back.'
