Sealy Posturepedic Reviews: Quick Outline

Buying A Sealy Posturepedic Mattress

Sealy is a well-established mattress brand; they’ve actually been around since 1882. They typically sell through retailers, both in-store (e.g. Macy’s) and online (e.g. US-Mattress.com).

If you order through US-Mattress, you’ll receive free delivery. This means you’ll need to schedule delivery and it will take a little longer than with your standard bed-in-a-box mattress, but once the bed arrives, it takes very little effort on your part. And, since the bed is delivered full-size it is ready to go in just a few minutes (i.e. no need to wait for it to decompress).

US-Mattress also typically offers a 120-night in-home trial so that you have plenty of time to make up your mind regarding the bed. For the record, four months is more than long enough to give it a yay or nay.

The only wrinkle in the in-home trial is that US-Mattress usually requires you to try the bed for at least 30 nights. This is to allow your body to adjust to the bed and to allow the bed to soften up (all beds soften with use).

If you decide that the Sealy Posturepedic Hybrid Kelburn is not for you, as of when we’re posting this review (late 2018), US-Mattress offered completely free returns. They don’t charge any shipping fees, restocking fees, or pain-in-the-butt fees. It should be completely free to return the bed. You can check the current policy on US-Mattress.com.

Also, the Posturepedic Hybrid Kelburn comes with a standard 10-year warranty.

Sealy Posturepedic Price And Coupon Code

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

SizePrice (MSRP)
Twin XL$1,274
King / Cal King$1,799

The one thing with Sealy products is that coupons are scarce since the mattresses themselves are sold through retailers, but the pricing is often times 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.

Posturepedic Mattress Construction & Design

Much like the name states, this is a hybrid mattress made with coils and foam. Let’s break down its construction, though, layer by layer.

First is a layer 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. A queen size Posturepedic Hybrid Kelburn II has about 1,000 coils total. On top of this layer is a couple layers of memory foam, which is what gives this bed it’s memory foam feel. These layers stack up to make a 12” mattress.

General construction overview of the Hybrid Kelburn mattress

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.

Special Cover On This Sealy Mattress

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 don’t know about all that, but we really like the grey and black design and how soft it is. The cover really gives this mattress a premium look.

Soft and comfortable cover

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.

Also, remember to rotate your bed every 3-6 months to help prevent any permanent indentations or sagging. This will help to extend the lifespan of your mattress. This bed is not meant to be flipped—the coils are meant to be the bottom layer of this bed, so make sure you keep it right side up.

What Sealy Posturepedic Mattresses Feel Like

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

The Hybrid Kelburn is about a flat 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 would 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 sleeper type, as well.

How Does It Handle Side, Back & Stomach Sleepers?

Yes. We think the Sealy Posturepedic Hybrid Kelburn II is a good option for back and stomach 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 that if you’re over 250 lb, we don’t think this will be a great mattress for back/stomach sleeping—it will end up being a little too soft.

Should be just fine for back and stomach sleepers (that weigh under 250 lb)

When beds are too soft, they let the heavier parts of the body (i.e. head, hips, shoulders) sag into the mattress, which causes the spine to curve. This can result in aches and pains in the morning. A properly supported spine prevents this.

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

Body Types Discussion

Because this is a thick, hybrid mattress, we think it will be good 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.

This is a thick and supportive mattress

This is a lot of mattress for very petite body types, but regardless, it’s still a good mattress. It will definitely work for individuals weighing under 250 lb. You can pretty much take your pick of sleeping positions and you should be just fine.

Will The Sealy Posturepedic Bed Sleep Hot?

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.

Will It Be A Viable Mattress For Couples?

We think this is a really nice mattress for couples. 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 who chugged too much water before bed and now has to use the bathroom every hour.

As for the edge support, it’s a little bit of a misnomer. As mentioned previously, the memory foam creates a divot where your body is—regardless of whether you’re in the center of the bed or along the perimter.

The problem here is that if you end up on the edge of the bed, that divot makes it hard for you to find your way back to the middle of the bed, so much so that it’s almost easier for you to just roll off onto the floor. 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.

Review Verdict

This is a really nice bed with a comfortable memory foam feel. It’s accommodating of any sleeper type and any body type. We like that it doesn’t heat up like 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.

How did the Slumber Yard get this mattress?

US-Mattress sent it to us because they thought we’d like to try it. We are in no way obligated to them to write anything good or bad about this mattress, or any mattress they send us. All opinions are purely that of the Slumber Yard team.

Does this mattress come with anything else?

Great question! When you go to purchase this bed through US-Mattress, you have the option to tack on a box spring, which comes in multiple models (even an adjustable base and some split ones), or a premium bed frame. So you have the possibility of getting a whole new bed set up showing up to your house all in one delivery. Pretty convenient, huh?
