Introduction

If you want a good night’s sleep, then you need a good mattress. But, knowing which one to pick can be daunting. There are so many brands, materials and sizes out there – knowing which one will work for you seems like an impossible task. But, our team of experts have done the legwork for you and tested mattress after mattress. Here are our top picks for the best king mattress out there right now.

In a nutshell

What you need to look out for

With a King mattress, you have more space in bed than the average person. This makes them perfect for couples who aren’t fans of cozy sleeping, and couples with young children or pets who like to crawl into bed with them. You won’t feel crowded in bed, even with the extra people if you use a mattress this size.

It also helps to make larger than average bedrooms look more put together and cozy. If you have a spacious master bedroom, then a king size bed helps to pull the room together.

4.6 / 5

See how we rate >

Key features

  • Zoned Support™
  • Medium firmness
  • Memory foam and springs

Great for

  • Light sleepers/couples
  • Any sleep style
  • Warm sleepers
One of the areas that the Casper Hybrid mattress shines is in it’s zoned support that has been built into one of the foam layers. This technology helps to keep you supported in any sleeping position in a way that provides minimal disturbance to the rest of the mattress. This means that couples who share a bed won’t wake each other up if they move around during the night. Perfect for King size mattresses.Thanks to its hybrid construction, it also does an incredibly effective job of regulating body temperature throughout the night. The individually wrapped coils help to promote air flow through the base of the mattress and through the three layers of breathable foam on top. Again, this is useful for king mattresses as they are often used for couples to share.

See how we rate >

Key features

  • Soft firmness
  • 4 foam layers
  • Stain-resistant cover

Great for

  • Side sleepers
  • Pain relief
  • Motion isolation
When you have a foam layer in a mattress that is referred to as the “could comfort layer”, you know you’re going to be sleeping on a soft, luxurious mattress. And that is exactly what you get with the Puffy mattress – it really lives up to its name. This does mean that the mattress may be too soft for some – especially those who are of a larger build. If you’re a heavier individual, you will probably sink down a little too far than is optimal.When our testers were trialing this mattress, they found that it was ideally constructed for stomach sleepers – which is rare when it comes to all foam mattresses. While they rated it high for all sleep positions, it really impressed us in this respect, so it’s definitely something to bear in mind if you usually sleep on your front.

The Leesa mattress has been constructed with its very own LSA200 foam on the top layer. This foam has been specially constructed to offer comfort paired with advanced cooling technology so you’re kept cooler while you sleep. This is especially useful for King mattresses as they can sometimes retain more heat than smaller sizes, so it keeps you and your partner at a comfortable temperature throughout the night.This mattress also has a number of glowing reviews across the web attesting to a reduction in back pain after switching to Leesa. Our own testers wholeheartedly agree, so this would definitely be a great choice of king mattress for those who have suffered in the past.

King Mattress Buying Guide

WHICH MATTRESS IS BEST FOR...

For most people, the purchase of a King mattress is for a couple to share together. Because of this, it’s important to choose a brand that has designed their mattress with this in mind. Mattresses with zoned support and anti-motion transfer are key to keeping both parties comfortable and sleeping throughout the night.

Even though Queen mattresses are the most popular size, by upgrading to a King, you’re giving yourself more space to stretch out and relax, as well as filling up more of a larger bedroom.

WHAT YOU NEED TO CONSIDER
When buying your King size mattress there a few things you need to consider before making your purchase.
 Materials / Construction

Choosing the right material for your mattress will depend on a number of things. The main construction types available for mattresses are foam, latex, innerspring and hybrid. There is a selection of these in our recommended list, so whichever you prefer, you’ll be able to find a king mattress of that construction.

 Firmness / Sleeping Style

Whether you’re a front, back, or side sleeper, having a King mattress means you have space to really stretch out and feel comfortable while you sleep. It is worth bearing in mind though that every mattress will have a different firmness level. Most memory foam mattresses will land on the firmer side, but there can be exceptions to this rule. It’s worth investigating the firmness levels of your chosen mattress before purchasing.

  Budget

Buying a King mattress is not always the most budget-friendly option, so if you’re conscious of price, you’ll need to factor this in. Mattresses today vary in price quite significantly, so even if you’re counting pennies, you’ll be able to find something to match your budget.

WHAT ARE THE BEST MATTRESS TYPES FOR KING MATTRESSES
We already mentioned that you have a number of options when it comes to the construction of your mattress, and choosing the right kind is just as important as any other factor. Here’s a quick rundown of the four types of mattress available.
Memoryfoam mattress
Foam / Memory Foam

Memory foam mattresses are usually great choices for people who prefer a firmer feel. They provide great support and help you stay in alignment by conforming to your body while you sleep. This also makes them excellent choices for back pain sufferers, as they help to relieve some of that pain while you sleep. Because of the deep depressions, your body makes in the foam, they may not be ideal for couples though, as it may affect each other’s comfort if your partner moves around.

Latex mattress
Latex

Latex is an option that has become more and more popular in recent years. It manages to combine the pressure relief of memory foam without the drawbacks of staying depressed when you move. While memory foam molds due to your body heat, latex does it by weight. This also means they tend to run cooler than foam mattresses too. They are also hypo-allergenic which can be important for people with allergies.

Innerspring mattress
Innerspring

Traditional innerspring mattresses are still a great choice for many people. They offer great levels of support, especially for combination or active sleepers. As they don’t mold to your body, it means that you can easily move around in bed without hindrance. Also, because they are not solid pieces of foam, they are more breathable than foam mattresses helping you to stay cooler.

Hybrid mattress
Hybrid

Combining the support of foam and the breathability of springs, hybrid mattresses can be a great option for many when purchasing their new mattress. As hybrid mattresses are always trying to work with improved technologies, they usually have zoned support and temperature regulation included – ideal for couples.

Other recommended mattress brands

Another great option for budget shoppers, the Tulo foam mattress is one of the newest brands on the block. While their review pool may be limited they are, on the whole, glowingly positive. The mattress consists of a top gel foam layer that helps keep you cool, a support layer in between, and then a durable foam foundation layer. And, just in case you’re worried about the brand being new, they also offer a 120-night trial so you can be sure it works for you.
Saatva’s foam mattress comes with the ability to customize the firmness level. You can choose from “plush soft”, “luxury firm” or “firm”, as well as being able to choose how thick you want it, so you know you’ll be getting the right mattress for you. While it’s not an especially budget-friendly option, the customization options more than makeup for this.
The Zinus Hybrid Gel Foam Mattress is a popular choice across the internet thanks to its specialized edge support. You can choose between 10” or 12” thickness to customize it to your exact specifications. The gel infused memory foam helps to keep you cool and comfortable, and all for a very budget-friendly price.
Technically, the Purple mattress doesn’t come in a box. But, it does come vacuum packed and rolled up tight into a small cylinder. Another hybrid mattress, this one comes with built-in motion isolation to help minimize disturbance to your partner if you move in the night, and also comes with a 100-night trial and 10-year warranty.

Top FAQs

What kind of bed frame works best with a king mattress?

Most mattress brands are compatible with a variety of bed frames including box springs, slats, divan, adjustable, or platforms. The bigger the mattress, the heavier the weight though – so you need to be sure your frame can withstand the mattress you choose.

Memory foam mattresses will also weigh more than spring or hybrid mattresses, so you may find that these work best on sturdier frames.

Should I buy my king mattress online?

A king mattress is a big purchase, so it’s understandable that you may not feel comfortable making the purchase online. While you don’t have the opportunity to try before you buy, the majority of brands offer sleep trials that allow you to try your new mattress over multiple nights. If the mattress isn’t for you, you can return it for a full refund within that time. So, there’s no need to worry about buyer’s regret here.

Should I get a foam, spring, or hybrid king mattress?

This all depends on your sleep style and firmness preferences really. But, if you’re buying a king size mattress for use as a couple then we recommend going for either spring or hybrid. These options offer levels of motion disturbance control that stops you from disturbing each other during the night.

 

With a foam mattress, you do get a nice firmer feel and personalized support, but with memory foam, there is less ability for movement as it molds to your shape and stays there even when you move.

How much should I spend on my King mattress?

King mattresses will generally cost more than standard sizes thanks to the extra material needed to make them. But, if you’re budget conscious, there are still many brands out there offering quality at a discounted price. All the brands we mentioned in this review offer King mattresses under the price of $2000, but the cheapest comes in at just $368 – so there’s something for every wallet.

Is King size the right size mattress for me?

King mattress dimensions are 76” W x 80” L, other than the California King, they are the largest size mattress available from most manufacturers. They are a great option for couples who desire more space while sleeping or couples who regularly have small children or pets sleeping in their bed with them.

 

You will need to make sure you have a king size bed frame in place, or buy one, especially for your new mattress. Depending on the size of your bedroom, it may be too large for your space. Although, king size meds do a great job at filling up space in larger rooms.

To wrap it up

Conclusion

Ideally, you want to replace your mattress every 7-10 years. Thankfully, the majority of brands come with a 10-year warranty, and some even come with a lifetime warranty to cover you for as long as you own it. Buying a new mattress is a big investment, so it’s good to know you’ll be covered for years to come while you enjoy your new king mattress over many peaceful nights.
