The Helix Midnight is a hybrid mattress with foam and coils providing pressure relief and support. The mattress fits side and lightweight back sleepers, but heavier individuals and stomach sleepers may prefer a firmer bed.
The coil unit features individually-wrapped coils to minimize motion transfer, so the Helix is good for couples with different sleeping preferences. The bed has thicker-gauge coils in the perimeter for added edge support, allowing you to use the entire surface of the bed. The Helix Midnight uses memory foam to reduce the pressure on the hips, shoulders, and lower back. Memory foam is known as one of the best materials that conform to the body to relieve pressure build-up.
What stands out?
- The Helix Midnight has a Soft Touch Design Cover made of soft-knit fabric. The cover enhances breathability, preventing the foam layers from overheating.
- This hybrid mattress features a comfort layer made of a blend of high-density memory foam.

The WinkBed mattress comes compressed in a box regardless of the size you choose. WinkBed ships the mattress directly to your door, which is convenient if you’re after a large bed like King or Queen. You can choose the firmness level based on your preferred sleeping position. Back and stomach sleepers may prefer the firmer models, while side sleepers should enjoy the soft WinkBed.
This hybrid mattress is suitable for hot sleepers, thanks to its gel-infused foam. The gel prevents overheating and helps reduce night sweats by cooling the body. The second layer is SupportCell foam, followed by the innerspring unit with 8-inch coils and a layer of polyfoam for added support.
What stands out?
- The innerspring layer has five zoned support points to relieve pressure in sensitive areas while providing support and responsiveness for easy repositioning.
- The WinkBed has a Tencel cover that enhances breathability, preventing the foam layers from overheating.

If you struggle with back pain, it’s possible that your king-size mattress isn’t providing enough targeted support. The Saatva Classic aims to provide just that, with multiple features that encourage healthy spinal alignment.
This luxury innerspring model includes Lumbar Zone® Technology that ups the support in the mattress’s middle—directly under the portion of the spine that most needs a sturdy foundation. It also has a dual-coil design that combines a base coil unit with a separate system of pocketed springs. Together, these coils lend the bed helpful responsiveness and even more support, a beneficial combo for achy backs.
Why do we love it?
- Topping off Saatva is an euro pillow top crafted from organic cotton. Beneath this is a layer of memory foam that helps with pressure relief and increasing the overall comfort of the bed.
- Saatva offers free white glove delivery, meaning there is no unboxing period or heavy lifting. You can throw sheets and pillows on it right away and enjoy a luxurious night of sleep right away.

Five different layers of foams and individually wrapped coils help this bed reach its 14-inch profile. This model was made to help sleepers obtain maximum shuteye by targeting their comfort and support needs. This bed’s price tag is cheaper than many other luxury brands but does not sacrifice quality.
The DreamCloud Premier has a medium firmness that should work well for couples, and the brand uses individually wrapped coils to help minimize motion transfer for a more peaceful rest.
What makes it special?
- DreamCloud Premier is furnished with a Cashmere-blend cover that’s quilted to 2 inches of foam, including 1 inch of gel-infused memory foam. This should provide excellent pressure relief for those struggling with aches and pains.
- Reinforced edges allow couples to take advantage of the full surface area and should be helpful for those needing support getting out of bed.

The spring unit and the proprietary foams in the Dawn give it a firmer feel that’s perfect for people who prefer minimal sinkage. Instead of classic memory foam, this bed features Helix Dynamic Foam—a material that emulates the airy feel of latex—as its first foam layer. Back and stomach sleepers should appreciate the even, stable support that this material offers.
The Dawn also cools down sleepers with a breathable cover, the airflow around its coils, and foams that avoid heat retention. (If you want extra cooling power, you can upgrade the cover to a GlacioTex™ version.)
Why does it stand out?
- The Dawn balances comfort with palpable support. Our reviewers felt that they were resting “on top of” rather than “inside” the mattress.
- The long sides of the Dawn have reinforced coils for sturdy edge support.

The Emma Original king-size mattress is especially affordable when compared to competitors—the brand commonly offers it at sales prices of less than $1,000. That’s a desirable deal when you consider the thought that went into its multiple foam layers and reinforced edges.
Although some foam mattresses can be inefficient at cooling, the Emma fights off heat with a moisture-wicking, breathable cover and a layer of AIRGOCELL® foam, which vents away excess body heat. The HALO® Memory Foam beneath it contours to key pressure points and helps to encourage proper spinal alignment.
What else should you know?
- The durable foam base that acts as this bed’s foundation is impressively resilient and engineered to resist sagging over time.
- This king-size mattress is also a great bet for couples, as its foam layers restrict motion transfer for uninterrupted rest on both sides.

Hybrid mattresses offer some impressive perks for shoppers because they’re built with both foam and coils. The Bear Star Hybrid is a 13-inch tall mattress equipped with five premium layers.
The first layer is a copper-infused memory foam that should provide plushness and temperature regulation. Below this memory foam is a layer of comfort foam, which is made to adapt to different body types and sleep positions, a benefit for couples sharing a King-size bed. This layer also serves as a transitional unit between the top foams and the coils below, while also maintaining responsiveness and airflow.
Why do we love it?
- The coil unit is really where this bed shines for support. This 8-inch thick innerspring layer should ensure your spine remains well-aligned throughout the night.
- The base of this bed is a highly-dense foam for added durability and long-lasting use.

How Big is a King-Size Bed?
A standard king-size mattress is 76 inches wide and 80 inches long. These dimensions make king beds a full 16 inches wider than queen beds—they give you more than a foot of added lateral space.
Although these are the typical dimensions of a king-size mattress, there are nuances when it comes to the type of king bed you buy.
Types of King Beds
Standard King
A standard king-size mattress is one that measures 76 inches wide and 80 inches long. You may also hear it referred to as an Eastern king. It’s the most common incarnation of a king-size bed.
California King
A California king mattress is slightly narrower and longer than a standard king, measuring 72 inches wide and 84 inches long. It’s also known as a Western king, Cali king, or Cal king.
What’s the Difference Between a King and a California King?
A standard king-size mattress is wider than a Californa king, whereas a California king is slightly longer. In terms of surface area, a standard king actually has more space: 6,080 square inches, as opposed to the Cali King’s 6,048.
So, why you might buy a Cali king over a standard king? Certain sleepers—especially tall ones—appreciate the extra length. Its dimensions may also just work better with your bedroom setup. The king vs. California king debate is long and storied, with good arguments on either side.
Split King

A split king mattress is exactly what it sounds like: a king-size bed, split down the middle into two separate sides.
Split kings are ideal for couples who want to sleep beside one another but have notably different preferences in terms of comfort. For example, maybe you like a soft mattress, but your partner prefers an extremely firm bed. With a split king, you wouldn’t need to compromise.
Often, a split king will be two twin XL mattresses lined up side by side. This setup works well with a split adjustable base—sleepers not only get the feel they want from their bed, but they can also manipulate the position of each mattress independently.
Some companies make split kings that are separated at the head of the mattress but conjoined at the foot. These mattresses can be used with adjustable bases that only reposition the head of the bed.
California kings can be available as split kings as well, though they’re a bit tougher to find than standard split kings.
Pros and Cons of a King-Size Bed
Pros
- Lots of Space: King-size beds offer the most surface area of any standard mattress size.
- Room for Couples, Kids, and Pets: A king-size mattress can fit two (or more!) sleepers comfortably.
- Built for All Body Types: Kings are robust mattresses that can typically accommodate petite and large bodies alike.
- Better Motion Isolation: More space means less disturbances from your sleeping partner.
Cons
- Cost: Given their impressive size, king-size mattresses can be more expensive than smaller models.
- Setup Can Take Effort: You’ll need a bedroom big enough for a king-size bed, and potentially someone to help you maneuver it into place.
King-Size Mattress Shopping Considerations
Material

Beds come in all shapes, sizes, and makes. The material that sleepers choose to sleep on is going to drastically affect how they rest.
The most common materials are coils, polyfoams, memory foams, and latex. Many beds today use a mix of all of these in their construction. Here is a quick breakdown of what you might see.
- Coils: Most innerspring mattresses these days don’t use the same type of springs your grandma and grandpa grew up on. Many bed-in-a-box brands use a pocket coil that keeps the bounce while isolating motion. These are typically part of a hybrid and topped with some sort of foam.
- Foams: There are a lot of different types of memory foam mattresses out there, but the two most common are memory foam and poly foam. Memory foams are going to be slow responding and contour tightly to curves for pressure relief. Where poly foams will have more of a quick response that helps wipe away strain.
- Latex: Latex mattresses are made out of latex, which is a type of rubber foam. There are typically two types – Talalay and Dunlop latex. These differ in construction but have a very similar feel and quick responsiveness, gently contouring to sleepers bodies and cradling their curves.
Preferred Sleeping Position

What position the shopper sleeps in should determine what type of bed they want to order. The following are the four most common sleeping positions: back sleeper, side sleeper, stomach sleeper, and combinations sleeper.
Side sleepers typically like a soft bed that can relieve pressure from their hips and shoulders, as these areas put more pressure into a bed over a smaller surface area.
Back sleepers usually enjoy something that can help distribute their weight evenly over the surface of the bed. A medium feel often works for these folks as this will fill in the gap between their hips and shoulders without throwing off their alignment.
Stomach sleepers often drift towards a firmer bed. These types of mattresses keep their hips elevated and level with their shoulders. An overly soft bed could cause their hips to dip too low into the mattress.
Combination sleepers need a bed that targets all 3 sleeping positions, usually something with a medium feel and more responsiveness to help them move around.
Whatever position you sleep in, be sure you are getting something that caters to your body type so you can get the proper support your body needs.
For more information, see our article on the Best Sleeping Positions.
Firmness Level
The firmness of your mattress is going to affect how you sleep. Something overly soft can leave you feeling stuck in bed, while something too firm can feel like concrete.
Beds are usually categorized as Soft, Medium, or Firm, with some variance in between. Certain brands may use different firmness titles, so reach out if you are unsure. For more info, check out our complete mattress firmness guide.
Sleeping Partners
King mattress could be a great bed for couples wanting to sleep together but don’t want to fall asleep cuddling. This lets sleepers spread out while also giving more room for sexual activities.
If you have kids, a King size mattress offers enough space for family cuddles in the morning.
Trial Period
Most companies offer some sort of trial period. Some brands even offer up to a full year. These trials allow shoppers to try these beds out in their homes within the allotted time and if they are not satisfied with their purchase they can either return their mattress or exchange it for a new model.
Warranty
Brands offer varying warranties, some even provide lifetime protection. Warranties typically cover manufacturing errors or abnormal wear and tear of a product. If damage occurs within the time of the warranty, the brand will usually ship their customers a new mattress.
Certifications
These are given by third parties that test beds for safe amounts of chemicals and heavy metals. Certifications are also given for brands that have gone above and beyond national safety requirements and strive to clean up their production with organic and all natural materials and manufacturing. These certifications can vary, so be on the lookout between brands.
Additional Features
Some brands will provide extra services and features. This could be anything from handles that make the bed easier to carry, all the way to White Glove Delivery, a service where your bed is installed for you. Some mattresses may be hypoallergenic, a smart bed, or have special features that help with edge support or cooling.
