A better king size mattress for all sleepers

King

76" x 80"

Overview

King mattresses (a.k.a. Eastern Kings) measure 76 inches by 80 inches and are a top choice among couples. These mattresses have the same dimensions as two twin XLs pushed side-by-side, so they offer plenty of room for two adult sleepers. Kings don’t fit in every bedroom, though, and are best suited for master bedrooms and larger apartments. Browse our king size mattresses, starting at $1199.

Who are king size mattresses best for?

We recommend king size mattresses for couples since they offer 38 inches of personal space on either side of the bed—perfect for two sleepers.

  • The perfect fit

    Extra wiggle room

    King size mattresses are 76 inches wide, offering plenty of room to sprawl out without impeding your partner's space.

  • Great for couples

    Ideal for families

    If you share your mattress with a partner or your children, a king size can comfortably accommodate more than one sleeper.

  • Roomy but compact

    Fits most master bedrooms

    Most master bedrooms are large enough to fit a king size mattress, so you don't have to worry about space.

How much do king mattresses usually cost?

We all approach mattress shopping with an idea of what we'd like to spend. Before you shop, it helps to have reasonable expectations and understand how much quality your dollar can (and cannot) buy.


First, let's get this out of the way: you don't have to spend thousands of dollars on a high-quality mattress. Beds that cost upwards of $3,000 may be marketed as the peak of luxury, but that's typically all the high price tag really signifies.


With that said, there are some added mattress features you may need to raise the price of a basic model. For instance, if you're looking for a bed with cooling technologies or added lower back support, these added materials tend to bump up the cost a little bit.

Mattress detail

Common mattress features increasing mattress cost

  • Cooling technologies, such as gel foam, copper-infused foam, or plant-based foam
  • Proprietary foams or technologies (materials made exclusively by and for the brand)
  • Edge support (in the form of poly foam or other materials reinforcing the edges)
  • A quilted Euro top layer (Euro pillow tops are more expensive than plush pillow top mattresses because they contain higher quality materials)
  • A longer than average warranty (average is 10 years)
  • Thicker comfort foams (in general, softer beds use more layers, and are therefore more expensive)
  • Eco-friendly materials, such as organic cotton, latex, or plant-based foams
Mattress Type Low End Price High End Price
Foam $250 $4,000
Innerspring $300 $3,000
Hybrid $250 $4,000

Are online mattresses high-quality?

Bed in a box mattresses are everywhere, but the concept of buying a mattress from your laptop or smartphone and getting it shipped to your door is still fairly new. Foam mattresses, in particular, lend themselves well to online mattress brands because they can be easily compressed down and rolled up to fit in a compact box. What's more, online mattress brands cut out the middleman, overhead costs, and inflated prices associated with brick and mortar retailers, giving customers the opportunity to snag a high-quality bed for a good price.


But are beds in a box really high-quality? Let's compare our Amerisleep mattress models to a typical foam bed found at a mattress store.

What is the Amerisleep difference?

Traditional innerspring mattresses are still popular today. Chances are, you've slept on an innerspring before—they're still frequently used in hotel rooms and college dorms because they're relatively inexpensive.


Most innersprings are made with steel coils in the core, increasing airflow through the bed, and the top comfort layer is a quilted Euro or pillow top made of poly-foam, memory foam, or latex foam.


Despite their popularity, coil mattresses aren't long-lasting, having an average lifespan of five years. In fact, the customer satisfaction level for innersprings is the lowest of any mattress type.

Absolutely love our AS3!

We absolutely love our AS3! We both had back pains prior to purchasing this bed and can honestly say, after 4 months, we haven't noticed a single ache or pain since. Would purchase again and again!

Sarah B.

Lake Charles, LA

My AS3 mattress is the best!

I purchased the AS3 mattress 3 months ago, and it has been a lifesaver. My husband and I have back issues, and we needed a bed that would help us get quality sleep. We have always struggled with being able to sleep through the night due to aches and pains and now that we have been sleeping on our AS3 mattress for 3 months now, we finally are able to sleep comfortably through the ENTIRE night!

Tay Tay

TREAT YOURSELF! A great night of rest is priceless

I purchased the AS3 and couldn't be happier, I now own 2! A king size and a king size and I will never buy another brand again. I would definitely recommend the king size AS3 over and over again, if you're considering buying this mattress because you're not getting great sleep or you're simply due for a new mattress... TREAT YOURSELF. I promise you will not regret it.

Want to sleep till noon?

We've slept on this bed for 9 months now. It's the perfect blend of softness and support. It's so comfortable we have accidentally slept till noon on many occasions! My husband has had knee and shoulder surgery and this bed is comfortable for him to sleep on his side. My back and hip pain from standing at work all day is decreased. My kids are always trying to sneak in to sleep on it. This is the best bed we've ever owned.

Just What I Needed!

We have had our Amerisleep AS4 for about two months now. It is living up to the hype so far. My husband and I both have back problems and needed support plus give in the mattress. The Amerisleep AS4 fits our needs perfectly (for reference purposes, my husband and I are both under 160lbs). In fact, the first night we had our new Amerisleep, my husband slept for 10 hours straight! That has never happened in the 20+ years we've been married!

Very satisfied customer

Love the mattress! I have back problems and this mattress is so comfortable. I sleep better and the usual soreness I felt every morning with my previous mattresses has disappeared. We liked the first mattress so much, we bought another for the guest room.

Sissa

Dothan, Alabama

I now know what good sleep feels like

I was skeptical of ordering a mattress online even though I was able to test it in the store prior to ordering. The delivery was a breeze and the mattress didn't even need to off-gas, but it's the sound sleep provided that is the point of this review. I sleep on my back now and haven't in years. Who knew I was a back sleeper? This mattress (A2) is firm and supportive yet still soft and cozy and has provided the best sleep I've ever had. Thanks for making me excited about bed again!

Dominick

Portland, OR

Excellent Product, Excellent Sleep

This is an excellent mattress. I was a bit worried about getting the AS2, as I am primarily a side sleeper, but I am getting the best sleep of my life whether I am on my side or my back. The best part is how sturdy yet quiet the bed is. My partner and I go to sleep and wake up at different times, and neither of us notice when the other gets in/out of bed. I also run pretty hot, and in my previous bed was no stranger to waking up sweaty, but this mattress keeps me cool and dry.

Nick

I would definitely buy this product again.

We are both back and side sleepers and the mattress works great for us. This mattress made sleeping with a bad hip before and after hip replacement surgery possible. Our old mattress made sleeping especially on the side intolerable.

Dennis S

I absolutely LOVE this mattress!

I have always had back issues waking up and difficulties getting to sleep on my current mattress and previous ones but when my new mattress was delivered I noticed a difference the first night! I now look forward to using it and sleep like a rock.

Worth the money!

This is my first memory foam mattress. I have always had a pillow top. I was afraid to order the wrong type for my body/sleep type. I spoke with customer service and was recommended the AS5 since birth my husband and I are smaller people (I'm 112 pounds and 5'2 and my husband is 5'8 and 165 pounds), and we both are side sleepers primarily (I also sleep on my back). I was worried it would be too soft or not soft enough, but it is perfect.

Liked the king size so much I bought my daughter one!

I like a firm mattress and shopped in stores for months trying to find the right one for me. None were comfortable. I took a shot with the Amerisleep AS1 after many reviews said it was a firm mattress. Best decision! It was so comfortable that I turned around and bought one for my daughters full size bed.

I Love This Mattress

My wife has a bad back so we needed a very firm mattress. Our old mattress was sagging and had to go so we bought a very nice split king mattress but it was just not firm enough. We saw Amerisleep and took a chance. No more back pain - we are amazed but love it. Would highly recommend.

Best bed money can buy

My wife and I use this bed every single night now. We chose the firm model in hopes we would wake up with less aches and pains after a night of sleep. It’s done that and more! Super comfortable bed while being extremely sturdy. Can’t believe how easy and fast the purchasing process was either. I would highly recommend this bed to anyone and everyone. What are you waiting for?

Frequently Asked Questions

Where can I put my new king size bed?

When it comes to mattress foundations, you've got plenty of choices. Memory foam mattresses can be used with platform beds, slatted foundations, or an adjustable base. Typically we would not recommend using any memory foam mattress with a box spring because they can cause the foam to sag.

If you do use your king size memory foam mattress with a slatted base, make sure the slats are no more than 3 inches apart. The type of bed frame you pair with your mattress can affect its lifespan, so make sure you read the manufacturer's foundation guidelines— otherwise, you risk voiding your warranty.

No matter which foundation you choose, make sure it meets the requirements set out by the warranty. If you select a bed frame that is incompatible with your mattress, you run the risk of voiding your warranty protection.

An adjustable bed base is a great option if you're looking for extra customization. Adjustable beds allow you to elevate your legs and head, which improves circulation, minimizes snoring and sleep apnea symptoms, and takes pressure off your back. Not only are adjustable bases great for healthy sleep, but they're convenient too— you can maintain a healthy posture while you read, watch TV, or relax in bed.

Some companies offer adjustable mattress sets so you can get a new mattress and an adjustable frame at a great price.

What is the best king size mattress?

The "best" mattress should do at least three things

  1. Support your back
  2. Ease pressure points
  3. Last a long time

Obviously, because you spend one third of your life in bed, you want it to be comfortable! And because it's a big investment, you expect it to last. The best mattress for you depends on your mattress type, comfort level preferences, and budget. And, if you share your mattress with a partner, you have to consider their preferences too!

Before you choose a king size bed, consider the pros and cons of each mattress type.

Memory Foam Mattreses

Memory foam isn't exactly new in the mattress world, but recent innovations have made it more and more popular. The most recent trend to boost memory foam's availability is the bed in a box revolution, which cuts out the middleman (brick and mortar stores) and ships mattresses directly to customers' doorsteps. Memory foam mattresses are easy to compress and ship in a box, so they go hand in hand with this new delivery format.

A basic memory foam mattress model has 2-3 layers of foam with some variation depending on the firmness (firmer mattresses have fewer layers, softer mattresses have more). A true memory foam mattress has memory foam in its comfort layers and then a firmer, stiffer foam as the bottom layer (usually poly foam).

Memory foam is dense and soft— two characteristics that lend themselves well to a silent, pressure-relieving sleeping surface. However, this same high-density foam is known to trap heat. Manufacturers of this popular foam infuse it with cooling gel, green tea, charcoal, graphite, or copper to dissipate some of the heat.

Amerisleep's memory foam, known as Bio-Pur®, is partially plant-based, making it more responsive and breathable than traditional memory foam.

Innerspring Mattresses

Innerspring mattresses are still the most common, widely available mattress type. They're bouncy thanks to their coil support cores, but they offer little by way of pressure relief because of their thin Euro or pillow tops (comparable to the comfort layer in a memory foam mattress).

Innersprings have one advantage over memory foam: they sleep cooler because air can easily move through the bottom coils. However, these same coils lead to sagging and deterioration after only a few years. This is probably one reason memory foam is starting to take over as the most popular type of mattress.

Hybrid Mattresses

Hybrid mattresses look and feel quite similar to innersprings, but there's a couple of major differences: first, hybrids contain more foam in their top comfort layers. In fact, a hybrid must have 2-3 inches of foam to even be classified as a “hybrid.” Second, hybrids are often made with individually-wrapped coils, also known as Marshall coils. Each steel coil is wrapped in soft fabric or foam to alleviate motion transfer and noise (two problems common to innersprings).

Latex Mattresses

Latex is popular because it feels similar to memory foam, but it's not always made with polyurethane like memory foam. For that reason, it appeals to eco-friendly consumers. Dunlop latex is harvested from the sap of a rubber tree, a renewable resource. Dunlop feels firmer than the other latex type, Talalay. Talalay latex also comes from rubber tree sap, but polyurethane fillers are added to give it a softer, bouncier feel.

Latex is not as easy to find as memory foam, nor is it available in a wide range of budget options. However, it's incredibly durable, so some prefer to invest more money in it because of its longevity.

Are there different size king beds?

Some basic mattress sizes are available in a few different iterations, like the Twin XL or the Olympic Queen. When it comes to king size beds, there are really only four variations: the standard king, split king, California king, and split California king.

Many couples like using split mattresses with an adjustable base since that allows for the ultimate customization.

Do two twin beds make up a king?

No, two twin size beds are not the same size as a king. However, two twin XL mattresses are the same size as a regular king size bed. If you're looking for a mattress both you and your partner can adjust to your preferences, we recommend a split king mattress.

Does my weight affect the mattress feel?

Yes, your body type can change the way your mattress feels. Heavyweight sleepers tend to compress the memory foam layers more deeply, and thus prefer a very soft mattress (like the AS5, which has five layers), or a fairly firm mattress (like the AS2).

Lighter sleepers typically like soft beds since they don't compress the mattress much at all. Again, your weight and sleeping position both affect which firmness you prefer. No matter your body type, make sure your mattress uses a base that will not sag. A great mattress holds up under lots of pressure without losing support.

How do I know which mattress firmness is best?

When we hear “firmness” associated with a mattress, some of us shy away— we prefer a plush, cradling surface to sleep on. However, others need firm, steady support with very little give. Much of this firmness preference stems from the way we sleep, or our sleeping position.

To avoid confusion here, we suggest familiarizing yourself with the firmness scale. Many online mattress brands use it to classify each mattress model they sell. The scale is easy enough to decipher— it goes from 1-10, with 1 being plush and 10 being extra firm. Most mattresses do not fall at the extreme ends of this scale because if they did, they wouldn't be usable.

We classify each Amerisleep mattress by firmness and use this same scale to help customers differentiate between each model.

Firm (firmness scale: 8-9, AS1)

We classify each Amerisleep mattress by firmness and use this same scale to help customers differentiate between each model.

Medium-Firm (firmness scale: 6-8, AS2)

Medium-firm mattresses have been proven to alleviate back pain better than any other firmness. It used to be that most people assumed soft mattresses were best the best mattresses for back pain, but we now know that beds with too much soft cushioning can cause the back to sink down, putting pressure on it and leading to pain.

Medium (firmness scale: 5-7, AS3)

Medium mattresses tend to be the bestsellers for most mattress brands— maybe that's because they appeal to side sleepers, who make up the majority of the population. Medium mattresses have that perfect “Goldilocks” feel; they're not too soft or too firm. Medium beds are widely recommended for side and combination sleepers because they alleviate pressure points and provide enough spinal support.

Medium-Soft (firmness scale: 4-5, AS4)

Medium-soft mattresses are often constructed with the same amount of support and transitional foams as medium beds, but their comfort layers are thicker. You'll probably enjoy a medium-soft mattress if you're a dedicated side sleeper or you just like a bit more cushioning under your weary joints.

Soft (firmness scale 2-3, AS5)

Soft mattresses have the thickest comfort layers, but they should be reinforced with transitional or support layers to ensure they won't sag. Even the softest mattress can still keep the spine aligned as long as it has high-quality support foams in its middle and foundation layers.

How long should a good mattress last?

Your mattress’s lifespan depends on the quality of materials and how well you take care of it. With that said, some mattress types tend to last longer (or not as long) as others.

Mattress Type Average Lifespan
Amerisleep Mattresses 15-20 years*
Traditional Memory Foam 7-10 years
Innerspring 5 years
Hybrid 6-7 years

We recommend using a mattress protector to ensure your mattress lasts as long as it’s supposed to and is protected from stains or spills, which usually void the warranty.

What should I look for in a mattress warranty?

Your mattress should come with a warranty; in the mattress industry, a 10-year warranty is standard. Almost all mattress warranties come with the same provisions, with some variation based on the brand and mattress type. In general, your mattress warranty should cover the following manufacturing defects:

  • Sags below a certain depth (usually 1.5 inches or more)
  • Bunched or torn foam
  • Burst or bent coils
  • Broken zippers
  • Torn covers

Is memory foam safe?

Memory foam is made with polyurethane, a petroleum byproduct that creates a plush mattress. The EPA has declared memory foam to be safe, but some notice an off-gassing smell when they open their new memory foam beds. If you do experience this, open your windows and air out the bed for a day or two. The smell should dissolve within a few days.

What if my king mattress is too soft or too firm?

You can adjust your mattress firmness using a topper. While they are a temporary solution, they do work nicely to change the feel of a bed if you need a little something extra but don’t want to go out and buy a new mattress already.

Read mattress reviews and customer feedback to ensure the mattress you choose will complement your firmness preferences; that way, you won’t need to invest in a topper later on.

How long should sleep trials last?

A 30-90 night sleep trial is typical for most online mattress brands. The trial should last at least 30 days so you can adjust to the mattress and a healthier sleeping position. Sometimes our bodies get so used to sleeping a certain way on an unsupportive mattress, we hardly notice the mattress is causing us pain! Check to see if the mattress you’re considering comes with a generous sleep trial and an easy way to return the mattress if it ends up not working out.
