How Does the Sealy PosturePedic Bed Feel?

This mattress from Posturepedic has a soft, airy memory foam feel. When you lay down on it, you’ll slowly sink into the material, but it doesn’t hug you too much, so it’s not overwhelming. Rather than contouring around you, it creates a gentle dip where your body lies.

sealy posturepedic mattress review hybrid kellburn deal promo code discount firmness

The Hybrid Kelburn is about a medium on the soft-to-firm scale. As is typical of memory foam, it has slow responsiveness, but the coils help balance it out so that you don’t ever feel “stuck in the mud” the way you might with Zinus, for example.

Keep in mind that firmness is relative, though. The more you weigh, the more you’ll sink into a bed and the softer it will feel. On the reverse side, the lighter you are, the more you’ll lay on top of a mattress, and the firmer it will feel. You should take this into account for your sleeper type, as well.

Pressure Relief

Pressure relief is an important factor for many people, including side sleepers and those suffering from hip pain or arthritis pain. The Sealy Posturepedic mattress scores well in this category, thanks to its top layer of memory foam.


We’d say this mattress sleeps more temperature neutral. How hot or cold you sleep on this bed will probably have more to do with external factors, like what you keep your AC set to, what type of sheets you’re sleeping with, and your body weight.

Sealy PosturePedic Mattress Construction

Like the name states, Sealy Posturepedic Hybrid Kelburn is a hybrid mattress made with coils and foam. These layers stack up to make a durable 12” mattress accommodating for all body types. Let’s break down its construction, though, layer by layer:

sealy posturepedic hybrid kelburn mattress review contruction
  • Base layer – A foundation of zone support coils; in the center of the mattress, there are 20% more coils for support, and then the edges have more spread out coils
  • Transition layer – The center layer of this mattress is a layer of softer foam to neutralize the firm feel of the coils
  • Comfort layer – A layer of pressure-relieving memory foam, which is what gives this bed its memory foam feel

All of Sealy’s beds are designed and built in the United States. Also, all of the foams used in the mattress are CertiPUR-US certified, which means (in essence) that the mattress is safe to sleep on and was not made with certain harsh chemicals or metals.

Sealy Mattress Cover

We really like the cover of this bed. It’s made with a “MoistureProtect” fabric that’s supposed to draw moisture away from the body in order for you to stay most comfortable. We can’t speak fully on that because we don’t have a method to measure moisture levels, but we can say we really like the grey and black design and how soft it is. We think the cover gives this mattress a top-tier, premium look.

This cover isn’t removable, so if you happen to spill anything or have any mistakes, just mix some mild soap with warm water and spot treat it.


Since the Sealy hybrid contains a layer of pocketed coils, this bed should be more durable and last longer than all-foam types. Coils are better at handling weight than foam, which is why we recommend hybrid mattresses for heavier folks (more on that later).

Body Type Analysis

Keep in mind, your weight could change your perception of the mattress firmness. As you could imagine, a mattress will feel different to a petite woman who weighs 100 lbs versus a 6’3 athlete who weighs 230 lbs.

  • Petite Body Types

    Smaller or lightweight individuals may find the mattress is too firm for their taste if they sleep on their side. Those who sleep predominately on their back, stomach, or a combination of all positions, though, might find it to be accommodating. If you’re looking for a mattress for petite people, make sure to take a look at our Best Mattresses for Petite People list.

  • Average Body Types

    If you have more of a moderate build, we think this mattress will provide a nice balance between support and pressure relief. For reference, we write all of our reviews (including our Sealy mattress reviews) from the perspective of an average-sized person.

  • Heavy Body Types

    Because this is a thick, hybrid mattress, we think it will be a great option for heavier people. The coils in this bed are supportive and durable enough to carry more weight than your typical all-foam mattress. You might want to stick to sleeping on your side though, as you might not get enough support if you lay on your back or stomach.

Sleeper Type Analysis

This Sealy Posturepedic mattress has a neutral mattress firmness that we think accommodates most sleeper positions including back, side, stomach, and combination.

  • Back Sleeper

    We think the Sealy Posturepedic Hybrid Kelburn is a good option for back sleepers because it’s firm enough to keep the spine in neutral alignment by supporting the hips and shoulders. The only caveat to this is if you’re over 250 lbs. We don’t think this will be a great mattress for back sleeping—it will end up being a little too soft.

  • Side Sleepers

    We also think the Sealy Posturepedic Hybrid Kelburn is pressure relieving enough for side sleepers. The memory foam in this bed does a good job of accommodating curves instead of fighting against them.

  • Combo Sleepers

    As you might anticipate, we found that the Sealy hybrid is a good mattress for combo sleepers too. You shouldn’t have a problem switching between sleeping positions, and you’ll get a nice balance of support and pressure relief.

Sealy Posturepedic Mattress Performance

Is Sealy Posturepedic Mattress Good For Couples?

If you’re looking for a mattress for couples, you might like Sealy PosturePedic Hybrid Kelburn for a couple of reasons. This includes its ample edge support and motion isolation.

Edge Support

If you and your partner like to spread out on your mattress at night, go for a king size. The edge support isn’t bad, but it’s not on par with Beautyrest Black or Stearns & Foster Addison Grace. Though, it’s definitely not a dealbreaker with this bed.

Motion Isolation and Noise

The motion isolating capabilities of this bed are quite good, as is the case with most memory foam beds. This is particularly helpful to light sleepers who don’t want to wake up along with their partner. 

Sealy Posturepedic Pricing

The Sealy hybrid is definitely not a cheap mattress, but it’s not expensive either. It’s in between, and all things considered, we think it’s a nice value.

SizePrice (MSRP)
Twin XL$1,574
King / Cal King$2,099

Does Posturepedic Offer Discounts?

The one thing with Sealy Posturepedic products is that coupons are scarce since the mattresses themselves are sold through retailers, but the pricing is oftentimes controlled by Sealy. Retailers will offer promotions—such as a free Visa gift card or gadget—but you almost never will find a proper coupon code. You can check US-Mattress.com to see current deals and offers.

Sealy Posturepedic Mattress Verdict

The Hybrid Kelburn Mattress from Posturepedic is a really nice bed with a comfortable memory foam feel. It’s accommodating of any sleeper type and any body type thanks to its middle-of-the-road firmness level and hybrid construction. We also like that it doesn’t heat up as other memory foam beds do and that it has a nice premium look. Overall, if you’re in the market for a memory foam mattress, we think it’s hard to go wrong with this one unless you’re a heavy back and stomach sleeper looking for a more firm mattress.

How Will My Sealy Posturepedic Mattress Arrive?

Sealy PosturePedic Mattress Vs. Other Brands

  • Posturepedic vs. TempurPedic

    Both PosturePedic and TempurPedic offer a comfortable memory foam/coil hybrid mattress. With that said, PosturePedic is more affordable than TempurPedic. TempurPedic also makes models specifically designed to help regulate body temperature and help you sleep cooler, making it a better choice for hot sleepers.

  • Posturepedic vs. Nectar

    One major reason why Nectar mattresses are different from PosturePedic’s Kelburn hybrid is because of its construction. The Nectar Mattress is made with all-foam and no coils, therefore, is more suitable for petite and medium body types. PosturePedic, on the other hand, is made with a supportive coil base and is more accommodating for heavy body types. Also, Nectar provides a full-year trial period and a lifetime warranty, beating PosturePedic’s 10-year warranty and 120-night trial.

How We Test The Mattresses

  • My Slumber Yard

    My Slumber Yard has been around since the beginning of the bed in a box craze. Our team has personally tested and reviewed over 175 mattresses so far, and we keep more than 150 beds in our office so we can compare them (and take afternoon naps).

    When testing mattresses, we evaluate the following factors:

    Construction: We cut beds open to see what’s inside and how it’s made.
    Feel: We check if it has a stuck-in-the-mud memory foam feel, or if it’s more of a neutral foam or a plush pillow top, etc.
    Firmness: We have our own firmness scale and evaluate how that may vary depending on your body and sleeper type.
    Pressure relief: We test what’s the sweet spot for different body and sleeper types.
    Support: How that changes by body/sleeper type
    Edge Support: This is important for couples who share a bed. Would you roll out of the bed, or can you sleep confidently close to the edges?
    Motion Isolation: We use the water glass test to see how the bed fares with motion transfer. This is another important factor for couples who don’t want to wake up when they move.
    Temperature Regulation: We use a temperature gun to evaluate if the bed warms up, stays neutral or actively cools while you sleep.
    Noise: This could be an issue in beds with coils or innerspring.
    Off-Gassing: Some beds could have a smell for a few weeks after unpacking, and we try to warn you about it.
    Company Policies: We also take into account policies such as shipping, returns, trial period and warranty.
    Value: We look at a bed’s price in the context of what it offers in terms of features and quality of materials and construction.
