About Our King Size Mattresses

At 76 by 80 inches, a king mattress is your best option if you’re sleeping with a partner. King size beds give each person 38 inches of space, or the equivalent of one twin bed per person. A king bed - 16 inches wider than a queen - is great for couples who like a little more personal space when they sleep. If your master bedroom is 10 by 12 feet, you’ll have enough room for a king mattress, two nightstands and a dresser, but it will be a bit of a tight squeeze. The ideal room size for a king bed is 13 by 13 feet or larger.

Whether you prefer your mattress firm, soft or in between, we have options for you. Our king size mattresses come in the comfort levels firm, plush and pillow top, because we understand that everyone has different needs when they sleep.

Or you may prefer our hybrid king mattresses, which combine both memory foam and innersprings.

We Have Your Next King Size Mattress

No matter what you’re looking for in your next king size mattress, City Mattress has you covered. Whether online or instore, we have the tools and the training to help your search for the ultimate sleep space end in bliss. Let us help connect you with the mattress of your dreams!

Define Your Needs

So you know you’re in the market for a king size mattress, but what kind of mattress do you really need? Our king size mattresses feature a wide assortment of types and materials, so you want ensure the mattress you choose is the right one for you. For instance, if you suffer from back pain, a firmer mattress can provide great spinal alignment. If instead you often sleep on your side, a softer surface will offer pressure relief for your shoulders and hips. In addition, temperature is an often overlooked aspect of a good night’s sleep, and your choice of mattress can affect that too.


Every king mattress at City Mattress has a softness rating from 1 (firmest) to 10 (softest). You can use this rating to guide you as you search for the best support. For example, plush and euro tops provide extra cushion for pressure point relief, which is most important to side sleepers, while firm mattress tops allow for more streamlined spinal alignment and back support. Mattresses rating higher on the softness scale can often raise your sleep temperature, since air flow is reduced the more you “sink into” your mattress. Conversely, a firmer sleep surface will expose more of your body to air, leading to cooler sleep.


A king size mattress can more than comfortably sleep two adults, even those of us on the larger side. At 76”W x 80”L, you have the option of space – you can cuddle your partner or leave space between, all depending on what each of you need. If length is more important than width for your comfort, a California king size mattress measures 72”W x 84”L. Lastly, if you or your partner are easily awakened, a memory foam or hybrid mattress may be ideal, since both help to isolate a sleeper’s movements from the rest of the mattress surface.

Adjustable Friendly

You might notice that most of our king size mattresses are adjustable friendly. This means you can pair them with an adjustable bed base. Something to keep in mind is that an adjustable friendly mattress doesn’t require an adjustable base – it simply means the option is there. If you’re curious about adjustable bed bases, the Sealy Ease 3 Adjustable Bed Base is an excellent starting point.

Why Material Matters

Traditional innersprings are still a great option, but it’s best to make sure you know which materials might best serve you. Our king size mattresses feature a wide variety of materials, each with a unique purpose. Most mattresses will combine these materials and technologies, so understanding how they work together can help you find the perfect mattress for you. Among the most common mattress types you’ll find are memory foam and innerspring, as well as combinations of the two.

Memory foam Memory foam is popular for a reason – originally developed by NASA, it’s a modern material that offers excellent support. In addition, the material molds around you as you heat it with your body. This molding quality works well for side sleepers, since it relieves pressure on the shoulders and hips while still providing solid support. A side effect of this, however, is a tendency to trap heat. This doesn’t have to be a deal breaker for warmer sleepers, since a large number of memory foam mattresses include cooling technologies to offset this issue. As a case in point, Tempur-Pedic dedicates entire mattress lines to keeping you cool while you sleep. To see an example, check out the Tempur-Pedic Tempur-ProBreeze Medium Hybrid Mattress.

Innersprings As mattress technologies go, innersprings are time tested. With their active resistance, they offer excellent support for stomach and back sleepers, keeping spinal alignment optimal. For a side sleeper, however, you may encounter pressure point soreness, in particular in the hips and shoulders. Of course, many innerspring mattresses address this with a pillow or euro top layer. See our own City Mattress Grand Teton Eurotop Mattress as an example of this. It’s worth noting that innersprings have a tendency to lose their tension eventually, resulting in sag.

Hybrid mattress Hybrid mattresses unite an innerspring core with memory or latex foam layers, addressing more than one sleep need in a single mattress. As a result, a hybrid mattress makes a great choice for couples who sleep differently, such as a back pain sufferer and their side sleeping partner. When combined with an adjustable bed base, a hybrid mattress can be the ultimate compromise. For a popular example, give the Simmons Beautyrest Hybrid Brx1000-Ip Medium Mattress a look.

Latex Another great option is latex, which features natural durability and excellent wear resistance. Latex is so durable that many latex mattresses offer warranties up to 15 years! Similarly to memory foam, latex conforms to the sleeper, though not as much. Its bouncier nature allows it to provide an experience between memory foam and innersprings – offering good resistance while still relieving uncomfortable pressure. Latex also sleeps cooler than memory foam, dependent on the mattress top. Overall, a latex mattress is a strong candidate for sleepers who need great support with pressure relief included. The PranaSleep South Beach Delano Plush Mattress is a perfect example that offers medium firmness as well as cushioned support.

Bed in a Box A king size Bed in a Box mattress gives you the option to ship quickly and receive your mattress in a convenient box measuring only a few feet long. As you might expect, many Bed in a Box mattresses are made of memory and comfort foams, which allows them to be packed and shipped in an overall smaller package. However, City Mattress also offers hybrid options for additional innerspring support. If shopping for and receiving your mattress without leaving your pajamas sounds good to you, a Bed in a Box mattress may be just the thing! We recommend the Casper Original Foam Mattress, or anything else from the Casper lineup!

Is a King Size Mattress Right for You?

No doubt about it – if you have the bedroom a space, you can’t beat the comfort of a king size mattress. Two adults can sleep in perfect comfort and even accommodate a restless little one. Furthermore, larger couples often find that a queen size mattress isn’t quite big enough, while a king size mattress provides plenty of room to stretch out.

Go Beyond Your King Size Mattress

Achieving the ultimate sleep oasis involves more than just your mattress. For that reason, City Mattress is offers a wide array of bedding and accessories to dial in your ultimate comfort. For instance, if feeling cuddled or cocooned is important to your rest, a weighted blanket might be the perfect answer. If you prefer more cushion than your mattress already provides, a king size mattress pad can give you more cushion to relax you into sleep. You can always refresh your bed’s look and feel by adding something from our king size linens and bedding collection. Of course, another great way to update your décor can be as simple as a new blanket or throw.

Enhancing your sleep experience may start with your bed, but there are many more ways to drift away. For instance, a dreamy fragrance can soothe your senses and help you destress at bedtime. If nighttime noises keep you awake, a sound machine can help your mind filter out the distractions. One important and often overlooked aspect of personal sleep comfort is a set of comfortable sleepwear. After all, your bedtime attire is closest to your skin, so it’s a serious consideration when you want the ideal night’s rest. Whatever gives you the edge in your quest for quality sleep, City Mattress can help you find it.
