Thinking About A Hybrid?

Choosing a mattress is a big deal. You’re making a commitment that will directly affect how you sleep and your sleep affects how you perform throughout the day. There’s no doubt about it, sleep is crucial and being comfortable is a must. 

When you’re searching for a mattress, you might not be ready or even want to make the jump to an all-foam mattress but you are interested in that conforming feel they provide. Well, you’re in luck. A hybrid mattress is just the ticket.

What Is A Hybrid?

Sealy's mattresses are the outcome of ages of engineering designed to offer outstanding support and comfort. A hybrid mattress combines the best of both memory foam and innerspring mattresses. Hybrid mattresses are a great way to experience the pressure-relieving benefits of memory foam while enjoying the traditional feel of an innerspring mattress.

Many people are curious about the benefits of memory foam and gel memory foam mattresses but are hesitant to switch to an all-foam mattress. A hybrid mattress is a great option since it combines innerspring systems with memory foam. Hybrids allow sleepers to enjoy the perfect blend of sturdy, responsive support and contouring comfort.

The springs inside a hybrid mattress are usually the same size and gauge as those inside a traditional mattress with a layer of memory foam laid on top for support and contouring. The presence of these coils retains that bouncy feel you’re used to as well. The layers of memory foam at the top offer that contouring, snuggling feel that it’s known for. Hybrid mattresses also tend to be a bit thicker than a standard memory foam mattress. Sealy has worked with orthopedic specialists to produce real support for your body.

We have a wide selection of Hybrid Mattresses, so you’ll be sure to find one that suits your needs. Today, we’ll look at the Copper II and the Kelburn II.

About Sealy Hybrid Mattresses

Sealy Posturepedic has made its mark with exceptional, deep-down support and comfort. 

These Performance Hybrid mattresses feature Sealy's new individually encased innerspring coil system which offers better-contoured support, unique to your body. For over 100 years, Sealy has made mattresses right here in the US, and their technology has gotten better and better over the years.

The Sealy® Posturepedic Performance Hybrid Series

Sealy's innovative hybrid mattresses provide a lightly-conforming comfort on top with stable, innerspring core support. They combine the best of both worlds without the downfalls. Here’s a closer look at two mattresses from the Performance Collection that are some of the best selling mattresses on our site.

Sealy Hybrid Copper II Mattress

The Sealy® Posturepedic Premier Hybrid Copper II Plush mattress is the successor to the Consumer Reports top-rated mattress, the Sealy® Posturepedic Hybrid Trust II mattress. This mattress has been upgraded to make it even more supportive and much more relaxing. The Copper II mattress brings together Sealy’s Ultra Firm Foam with SealySupport ComfortSense and Immersion Chill foams. This combination ensures a plush feel while still providing full support. You’ll also find both plush and firm options available.

The UltraStretch, High-Loft Knit cover offers smooth waterfall construction and is designed to be lightweight, durable, breathable, and very soft to create a body-hugging sensation. This fabric, along with the breathable side panels, encourages you to sleep comfortably and a little cooler the whole night through.

Here’s a more in-depth at its features:

Features

DuraFlex Coil Edge System

A high-density flexible coil edge that surrounds the mattress for more reliable edge support with a larger sleeping surface and increased durability.

MoistureProtect

The cover’s fabric is built to wick moisture away from your body throughout the night, assisting you to stay cool and comfortable.

Chill

Cool-to-the-touch technologies promote a restful sleeping environment.

Individually wrapped coils

Independently encased coils allow independent movement. This targeted support reduces motion transfer and allows the coils to respond to the natural curves and alignment of your spine.

Gel Memory Foam Top Layer

Conforming memory foam made of gel is added for further flexible, durable support.

Zoned Support

In the center portion of the mattress, nearly 20% more coils are packed into the bed for even better support where you need it most. The Sealy® Posturepedic Hybrid Performance Copper II mattress features a coil count of up to 1000 springs.

Sealy Hybrid Kelburn II Mattress

The Sealy® Posturepedic Kelburn II mattress offers durable all-over support with exclusive Posturepedic Technology™ for reinforced support where you need it most, similar to the Copper II. 

The Hybrid Kelburn II mattress also features individually encased coils, called the Sealy® Embrace Premier Coil System, and pairs that reinforced center with the CoreSupport Center that adds additional gel memory foam over the middle third of the mattress for incredibly comfortable support.

The Sealy® Posturepedic Kelburn II mattress is topped by the DuraFlex Fabric which is lightweight, durable, and extremely soft to the touch. The side panel fabric is much more breathable than the previous collection and allows for even better airflow to help you keep cool the whole night through.

Features

DuraFlex Edge

The entire surface of the top of the bed can be used thanks to the reinforced border around the edge of the mattress, which also creates a solid place to sit on the edge of the bed.

Half Foam & Half Springs

With a hybrid mattress, the best of both worlds is specially engineered of springs and memory foam for full-body support. The memory foam on top supplies body-conforming comfort.

Cooling Material

The chill material is 12 times more effective at drawing away excess heat so that your mattress remains cooler while you fall asleep and helps you to fall asleep faster and stay asleep longer.

Individually Wrapped Coils

Encasing allows each coil to move independently for targeted support and reduced motion transfer. The encased coil system also responds to the natural curves and alignment of your spine.

Gel Memory Foam Top Layer

A gel memory foam top half creates body-conforming comfort while reducing motion transfer.

Core Support Center

Reinforced gel memory foam in the center third of the mattress and 20% more coils create exceptional support and durability at a spot in the mattress that absorbs the most weight and wear-and-tear.

Specifications

  • Medium Firm - Supportive, but comfortable without being too soft.
  • Ideal for back and stomach sleepers.
  • Adjustable base friendly

Mattress Layers

Key Takeaways

sealy hybrid layers

Both these mattresses provide the comfort of a well-made Sealy hybrid mattress that combines the conforming feel of memory foam and the bounce of springs. They both offer cooling technology, though the Copper II does have a bit more of that. Additionally, the Copper II is just a bit thicker than the Kelburn II.

When choosing between the mattresses the key things to remember are how hot you sleep as the Copper II will be better, if you want a softer or firmer feel as the Copper II provides this while the Kelburn II is just available in medium, and your budget as the Kelburn II is a better option for those who are budget conscious. 

These are truly the deciding factors as they both provide the premium edge support, hybrid benefits, and memory foam with chill. The Copper II also provides one inch of Sealy® ComfortSense™ Foam for a bit more cushioning.

These American-Made mattresses are some of the best hybrid options around. Whichever mattress you choose, you’re sure to love it.
