Our take-Kicking off our best king-sizemattress review is the Brooklyn Bedding Signature mattress. It fits the bill for your average sleeper looking for a quality king bed that won't cost too much.

Our take-It's the best king-size bed for people who want the traditional memory foam feel you can find in a Tempur-Pedic mattress at a more wallet-friendly price.It has a thick memory foam construction, giving it a relieving and slow-responding memory foam feel. It takes a few seconds for your body to activate the foam, but once it does, the memory foam slowly contours around your curves and nestles you into the bed.

Our take-WinkBed is an affordable luxury mattress that’s widely accommodating. The steel coils and fluffy pillow top make the WinkBed mattress a standout choice if you’re looking for a supportive and durable bed.

Our take- The Sparrow Signature Hybrid from Nest Bedding is a unique mattress that's a particularly great option for couples, thanks to its dual firmness capabilities. If you and your partner have varying sleep preferences or positions (as many couples do), you can choose a different firmness for each side with the dual split options: medium/firm, firm/plush and plush/med. Even with the dual firmness, there's no awkward gap in the middle of the bed. This feature is available only in the Sparrow's king and California king sizes.

Our take-The DreamCloud Premier Hybrid is the best king-sized bed in a box mattress. It’s a premium, 13-inch-thick bed that combines layers of gel memory foam and durable coils. The hybrid construction gives the DreamCloud Premier mattress a nice mix of pressure relief and durability, with reinforced edges and reduced motion transfer.

Our take-You may not be familiar with Allswell, but you're likely familiar with its parent company Walmart. As its entrance to the bed-in-a-box game, Walmart introduced the affordable Allswell mattress. The Allswell mattress is a good hybrid mattress for the price of a low-budget foam mattress, giving it a well-deserved spot on this best king bed list.

Our take-If you live with back pain, you need a king-size mattress that relieves it, not adds to it. The Saatva Rx mattress was designed to alleviate back pain from chronic conditions like scoliosis or sciatica.

Our take-In a sea of bed-in-a-box mattresses, brands have to add a little sauce to their designs to make them stand out. The Layla Hybrid is unlike most other hybrid mattresses because it comes with a two-in-one deal. What I mean is that it's flippable, and you can sleep on each side of the mattress comfortably.

Brooklyn Bedding Aurora Luxe: Many mattresses make embellished claims about their cooling abilities, but the Brooklyn Bedding Aurora Luxe effectively cools with multiple cooling enforcements, including cooling foam, Titan Cool technology and a cooling cover. With three firmness levels to choose from and a strong hybrid construction, it's a versatile mattress that works for any sleeping position and body type.

Purple mattress: There aren't many mattresses out there like the Purple. It's made with a special gel-like material the brand calls its GelFlex Grid. It's squishy and firm at the same time, offering a nice balance of support and pressure relief. It has a medium firmness level that suits all sleeping positions.

Testing a king mattress is similar to how we test most of our mattresses, and we pay attention to a handful of important factors.

• Firmness: The measure of how firm or soft a mattress feels is an important factor in deciding if a bed is suitable for you or not. Firmness, a lot of the time, indicates how pressure-relieving or supportive a mattress feels. Side sleepers usually like a softer mattress because it offers more give, and thus, more pressure relief around the hips and shoulder areas. Back and stomach sleepers, on the other hand, tend to sleep better on firm beds that keep the spine properly supported. We test firmness by using our judgment and deliberating amongst team members. It's easier to test firmness when you have 100 different mattresses to compare it to.
• Construction and features: We take a close look at the construction of a mattress, which is a good tell on how it feels and how supportive it is for certain body types. We also consider any extra or special feature a mattress might have to stand out from the rest of the competition. Is it cooling? Does it have a special cover made with Celliant fabric or cashmere? Does it have an extra durable construction? We take all of this into consideration when testing mattresses and delegating best list picks.
• Performance: This refers to motion isolation, temperature regulation and edge support abilities. How well does a mattress perform when we put it to the test? We test motion isolation by having couples judge how it sleeps, or placing a glass of water at the end of the bed to see how much it shakes when we move. Edge support is tested by laying on the sides, bouncing and checking how sturdy it feels. Personal experience is also how we test temperature, with the help of a thermometer gun.
• Feel: Feel is a separate topic from firmness. This refers to how a mattress' materials are perceived. Is it dense and morphy like memory foam, neutral and soft like neutral foam, or supple and bouncy like latex foam? We like to describe the feel as best we can since you're unable to feel it through your computer screen.

When looking for the best mattress, you should take in some key considerations. You should follow the same guidelines when looking for a king-size bed, with the same considerations.

• Hybrid vs. foam: The more you weigh, the more supportive your mattress should be. Hybrid beds are best for all body types, including those over 230 pounds, while foam beds are typically ideal for people under 230 pounds.
• Firmness is a key indicator of how accommodating a bed will be. One of the first things to think about while looking for the best kingmattressis firmness. Are you aside sleeper, back sleeper orstomach sleeper? Side sleepers typically needsofter mattresses, while back and stomach sleepers benefit from a firmer mattress because having afirm bedwill help support the spine, decreasing back pain. Medium beds right in the middle are perfect for combination sleepers.
• Key featureslike cooling tech, edge support reinforcements and Celliant covers can help you decide if a bed fits your lifestyle and circ*mstances. Strong edge support is great for couples who share a mattress, while beds with Celliant covers are perfect for people with active lifestyles.
• Price matters when looking for a king bed. The bigger the bed, the more expensive it is. King beds are often more than $1,000, but there are budget options like Allswell to consider if you're looking for maximum savings.

Not everyone needs a king-size bed, but it is mighty convenient and comfortable during these situations:

• Couples who want more space than a queen size offers
• Taller people who don't want to feel cramped (queen beds are about 6.6 feet long)
• Sleepers who share a bed with their kids (king beds are wider than California king beds)

King and California king mattresses are the most popular of the king variety, but a host of beds are technically classified as king. Here's an overview of the different types of king beds if you're looking for something a little different.

What is a good price to pay for a king size mattress?

The average king mattress costs around $1,000 or more, depending on how premium of a mattress you're looking to buy. More affordable options are available for around $500 for budget shoppers who are looking to pay a little less.

How big are king mattresses?

A king-size mattress measures 80 inches long by 76 inches wide and 4 inches thick. Compared to a queen-size mattress, it offers the same length but with 16 additional inches in width.
