The Sealy Posturepedic Hybrid is a mid-range 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.
Our Verdict
The Sealy Posturepedic Hybrid is best-suited for side sleepers in the average and heavier weight categories. It offers fantastic body conformity for heavier people and very good body conformity for average people, so you'll sink into the mattress enough to relieve pressure on your arms and shoulders. The lighter parts of you will also sink moderately into the sleeping surface, which helps reduce pressure on areas like your knees. Still, heavier people may also prefer a bit more support for side sleeping. Additionally, lighter individuals won't compress the mattress enough for comfortable side sleeping.
Fantastic body conformity for heavier people.
Very good body conformity for average people.
Soft upper comfort layers help with pressure relief.
Poor body conformity for lighter people.
The Sealy Posturepedic Hybrid is fairly well-suited for back sleeping for lighter people. It offers adequate support to keep your spine aligned, and its plush upper layers help relieve pressure around your hips. It provides mediocre support for average and heavier people, however, who will probably want something firmer for back sleeping.
Adequate support for lighter people.
Soft upper comfort layers help with pressure relief.
Mediocre support for average and heavier people.
The Sealy Posturepedic Hybrid is best-suited for lighter stomach sleepers. It provides adequate support for people in that weight category, so your hips will stay fairly aligned with the rest of your body. Still, you may want a firmer mattress for stomach sleeping. It's not a good option for average or heavier stomach sleepers, as it's not supportive enough to keep your spine aligned.
Adequate support for lighter people.
Soft upper comfort layers help with pressure relief.
Mediocre support for average and heavier people.
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.
The Sealy Posturepedic Hybrid offers good pressure relief for individuals in the average weight category, who will compress the mattress enough for comfortable side sleeping. It offers even better body conformity for heavier people. However, it's less conforming for lighter people. While its upper comfort layers allow your whole body to sink in, which helps with pressure relief, lighter people will still need a plusher mattress for proper pressure relief when side sleeping.
Fantastic body conformity for heavier people.
Very good body conformity for average people.
Soft upper comfort layers help with pressure relief.
Poor body conformity for lighter people.
The Sealy Posturepedic Hybrid is a 'Medium-Plush' mattress that offers adequate support for lighter people. If you're sleeping on your back or stomach, your hips will stay fairly supported. However, it's much less supportive for average and heavier people, making it less suitable for back and stomach sleeping, especially.
Adequate support for lighter people.
Mediocre support for average and heavier people.
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 the course of 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 top priority, you may want to opt for something with 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 you 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 has excellent responsiveness. The mattress recovers its shape quickly after being compressed, and has a bouncy feel, which helps make changing sleeping positions easier and stops you from feeling stuck in place.
High responsiveness, so you can easily move around.

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 are available: 'Soft' and 'Firm'.
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 best-suited for average and heavier side sleepers. It's also a reasonable option for lighter back and stomach sleepers, although some medium-plush mattresses offer better support, such as the Serta Perfect Sleeper Innerspring. It's also a good option if you sleep with a partner since its great motion dissipation means movement is less likely to wake you compared to mattresses like the DreamCloud Classic Hybrid and Serta Perfect Sleeper Innerspring.
If you're looking for a recommendation, check out our picks for the best mattresses and the best mattresses for side sleepers.
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 best-suited for average and heavier side sleepers. It's a decent option for lighter back and stomach sleepers, although you may want a more supportive mattress.
This mattress offers good body conformity for average people, so if you're sleeping on your side, you'll compress it enough to relieve pressure on your shoulder and arm. It also provides fantastic body conformity for heavier people. However, if you're in the lighter weight category, you won't compress it enough for comfortable side sleeping.
This mattress provides adequate support for lighter individuals, ensuring that when sleeping on your back or stomach, your hips remain fairly aligned with the rest of your body. However, it provides mediocre support for average people and slightly worse support for heavier people. The heavier parts of your body will sink in further, making it less ideal for back and stomach sleeping, especially.
This mattress has a bouncy feel that makes it easy to change sleeping positions.
This mattress doesn't contour around you as closely as some mattresses, so less of the sleeping surface is in contact with your body. The lighter parts of your body will sink into it more than with some 'Medium' mattresses like the Saatva Classic, which helps relieve pressure and creates a slightly hugging feel.
It has excellent responsiveness. The mattress quickly recovers its shape after being compressed, which helps prevent a feeling of being stuck in place.
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. If you're looking for a similar option with even better motion isolation, you might be interested in the DreamCloud Classic Hybrid.
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.'
