    How Much Is a King-Size Mattress? Average Price & What to Look Out For

    A king-size mattress isn’t just where you sleep; we consider it an investment in comfort and quality of life. So, how much is a king-size mattress? The answer isn’t straightforward, as choosing one that fits your needs perfectly is a process in itself. Prices vary based on brand and other crucial factors that we will discuss in this article.

    But don’t worry, we’ve got you covered. This guide will cover everything you need to know as you search for the perfect king-size mattress, from materials and features to brand and value for money you should be looking for. Let’s start with the basics!

    What Size Is a King-Size Mattress?

    A king-size mattress is one that gives you 6,080 square inches of sleeping space, and it’s the best choice if you’re looking for plenty of room, whether you’re buying one to fit a couple, for co-sleeping with kids, or just love some extra stretching space.

    King-Size Mattress Dimensions in Inches

    • Width: 76 inches
    • Length: 80 inches
    • Surface Area: 6,080 square inches

    How Much Bigger Is a King-Size Mattress Than a Queen?

    A queen-size mattress is 60 inches wide and 80 inches long, and while it’s still an excellent choice for adults and couples for its balance of comfort and practicality, you will surely notice a difference in personal space. A queen is 16 inches narrower than a king, making for 1,280 square inches in surface area.

    Queens are a better fit for smaller bedrooms or apartments and are easier on the wallet. However, if you have little ones always hopping into bed, the added width of a king-size mattress will make all the difference.

    If you want to know how to find the right bed size for your needs, consider factors like your sleeping habits, whether you share the bed with a partner or pets, and the size of your bedroom. You can even measure your current bed and compare it to the dimensions of different mattress sizes to get a better sense of the space they offer.

    What Affects the Price of a King-Size Mattress?

    So, how do we balance comfort, durability, and features to meet our needs when buying a dream king-size mattress? If you’re ready to upgrade, you need to consider several crucial factors to help you answer the question, “How much is a good king-size mattress?” Here’s a breakdown of everything that influences the price tag and how to choose the best fit.

    How Much Is a King Size Mattress

    Materials

    The quality of the materials used in the mattress can drive costs up or down. For example, if you go for high-density memory foam, you get great comfort and support. Natural latex, on the other hand, is more flexible and eco-friendly, while organic fabrics like cotton feel soft on your skin. As said, high-quality materials cost more upfront, but they often last much longer.

    Here’s how to choose one:

    • Natural Latex: Durable, flexible, and eco-friendly. Go for latex if you want a balance of support and comfort, as this is often praised as an ultra-durable and sustainable option.
    • High-Density Memory Foam: Need relief from back or joint pain? Memory foam adapts to your body, so this may be your perfect fit if you need pressure relief and support.
    • Organic Fabrics: If you go for wool, you get hypoallergenic and sustainable! These fabrics are ideal if you have sensitive skin or want a load off your mind regarding kids’ allergies.

    Customizations

    Want adjustable firmness levels or targeted support zones? Custom features like these usually come at a premium price and target specific sleep needs, like back issues or couples with strict preferences. For those who need a mattress that can address back pain, customizations and picking the right type of mattress may help.

    Custom options can increase costs, but they’re often worth it for the added benefits if you want to tailor your mattress to your needs. So, for example:

    • Adjustable firmness can help you fine-tune your mattress to your comfort level.
    • Custom sizes allow you to match your space and personal preferences perfectly.
    • Extra support zones are great for couples who need minimized motion transfer.

    Additional Features

    Consider if you want to pay for extras like:

    • Cooling technology if you’re a hot sleeper
    • Motion isolation so your partner’s tossing and turning doesn’t wake you up
    • Edge support for added stability when sitting or sleeping near the mattress’ edges

    Typical Price Tiers of a King-Size Mattress

    To help you budget, here’s a quick overview of what you can expect to spend:

    Budget Range ($500–$1,000)

    Budget mattresses cover the basics and are great if the money is tight and you still need to buy one. They might lack advanced features like cooling technology or motion isolation, but they work well if you’re a heavy sleeper.

    Mid-Range ($1,000–$2,000)

    If you’re looking for a balance between cost and quality, mid-range options deliver. What we’ve loved most in our research are memory foam and hybrid constructions with added features like zoned support, making it the best fit for many buyers looking to upgrade from a queen-size bed.

    Premium Range ($2,000 and up)

    Premium mattresses, and especially king-size ones, offer the ultimate sleep experience. A comfortable and supportive mattress can promote deeper sleep cycles, where restorative processes occur. So, if you prioritize your well-being, consider investing in a premium mattress that caters to your comfort and sleep health.

    Types of King-Size Mattresses

    Not sure which type of king-size mattress suits you best? Below are some of the most popular options to consider.

    How Much Is a King Size Mattress

    Memory Foam Mattress

    A king-size memory foam mattress contours to your body, so it can work wonders if you are looking for pressure relief. It eases pressure points and helps us wake up without aches. Traditional memory foam retains heat, so it’s a big consideration if you’re a hot sleeper. If so, look for modern options with cooling gel layers or open-cell designs.

    Innerspring Mattress

    An innerspring mattress is a classic choice for a firmer, bouncy feel. The coil-based design offers excellent durability and airflow, so it can help keep you cool throughout the night, which is even better for hot sleepers.

    On the downside, innerspring models may not offer enough contouring. Some come with pillow tops for added comfort, but side sleepers will not find the same body-hugging effect as foam mattresses.

    Hybrid Mattress

    Can’t decide between foam and springs? A hybrid mattress could be the way to get the best of both worlds. They combine a coil system with the comfort of foam layers, but many hybrids also include high-tech features like cooling gels, zoned support, or enhanced motion isolation, so they’re a solid way to balance comfort and sturdiness. Note that hybrids tend to be more expensive!

    Best King Size Mattress for Specific Needs

    Looking for the perfect king-size mattress but not sure where to start? Here’s where different sleepers should begin their search for the right mattress.

    For Couples

    Sharing a bed shouldn’t mean waking up every time your partner moves; memory foam mattresses and hybrids are your best bet to ensure you don’t. Built to minimize motion transfer, these allow restless sleepers not to disturb their partners, and hybrid models go the extra mile to offer a balance of support and comfort to ensure both of you sleep soundly.

    For Hot Sleepers

    If you’re often too hot to sleep, start your search with an innerspring or cooling hybrid mattress. These are designed to promote airflow, and hybrid options with gel-infused memory foam are your best bet for helping regulate your body temperature at night. You can also look for mattresses with moisture-wicking covers.

    Consider pairing your chosen mattress with breathable bedding made from natural fibers like cotton or linen for optimal temperature control. Comfort and coolness? Check and check!

    For Budget Shoppers

    Searching for a cheap mattress? Basic innerspring models or budget memory foam mattresses can still deliver good sleep without emptying your wallet. They’re often less costly, but you still want decent durability and a solid warranty to achieve great sleep and stay on budget.

    King-Size Mattress Buying Tips

    Choosing a king bed doesn’t have to be complicated, and we’ll cover some crucial actionable tips below on how to do it.

    How to Choose the Right Mattress for Your Sleeping Position

    Your sleeping position matters more than you think! You should consider it when choosing your mattress because it can greatly affect how comfortable you feel.

    • Side Sleepers: If you love sleeping on your side, you’ll want a mattress on the softer to medium-firm side. This will cushion your shoulders and hips, giving you that much-needed relief and keeping your body aligned. Memory foam or hybrids are great choices here because they contour your body while supporting pressure points.
    • Back Sleepers: For back sleepers, choose a medium-firm mattress to maintain spinal alignment and support your body weight evenly. Too soft? You’ll sink and strain your lower back. Too firm? It might feel like sleeping on a rock. Hybrid options that mix supportive coils with comfy foam are the sweet spot.
    • Stomach Sleepers: For stomach sleepers, firmer mattresses are essential to prevent sinking in the midsection. This helps keep the spine neutral and avoids lower back pain [1]. Look for mattresses with firm foam layers or innerspring designs. Bonus points for zoned support!

    Finding the Best Value

    Getting the most bang for your buck is all about timing your mattress purchase and being savvy as you consider your needs and choose products that will satisfy them.

    Shop During Major Sales

    Sales events like Black Friday, Memorial Day, and Labor Day are goldmines for mattress discounts. Retailers often roll out deals and even offer free shipping or bundled extras. Planning your upgrade around these sales can save a ton on a top-tier mattress.

    Do Your Homework

    Take some time to read customer reviews. These can give you an honest look at durability and user satisfaction. A solid warranty shows the manufacturer stands behind its product. Aim for longer warranties, as they’re often a sign of better quality.

    Try Before You Commit

    Many brands now offer trial periods ranging from 90 to eye-catching 365 nights, so you can test the mattress in your home risk-free. This gives you plenty of time to decide instead of making a rushed decision in a showroom. Sleep on it (literally) to make sure it’s a good fit!

    Additional Considerations Before Buying a King-Size Mattress

    Let’s discuss what else you should keep in mind before buying a mattress for your king-size bed.

    King Size Mattress Dimensions and Room Fit

    A king-size mattress gives you plenty of space to stretch out, but before you bring one home, make sure your bedroom is ready. Ideally, your space should measure at least 12 x 12 feet, as this will leave enough room for other essentials like nightstands, dressers, or even a cozy seating area. You want your bedroom to feel spacious and not cramped.

    Shipping, Warranty, and Delivery Options

    Don’t overlook the perks! Keep an eye out for brands offering free shipping, white-glove delivery, or removing your old mattress. These extras make the setup process a breeze. Also, go for a mattress with a solid warranty (think 10+ years).

    Expert Insights

    A king-size mattress offers the ultimate luxury in sleep, providing ample space for couples, families with young children, or those who simply enjoy sprawling out.

    According to Dr. Shelby Harris, a sleep psychologist and author of The Women’s Guide to Overcoming Insomnia, “A larger sleep surface reduces disturbances from a partner’s movements, leading to deeper and more restorative sleep.” This extra space can be particularly beneficial for combination sleepers who shift positions throughout the night, ensuring they don’t feel confined or restricted.

    Mattress construction and materials also play a crucial role in sleep quality, and experts emphasize the importance of choosing the right support level. “High-quality king-size mattresses incorporate zoned support and pressure relief to maintain spinal alignment,” says Michael Magnuson, founder of GoodBed.com.

    Hybrid models, which combine memory foam and innerspring coils, are often recommended for their balance of comfort and support. Additionally, temperature regulation features—such as breathable foams or cooling gel layers—can significantly improve uninterrupted, comfortable sleep, so bear this in mind the next time you buy a king-size mattress, or even better ask in relevant subreddits about other people’s experiences.

    FAQs

    Below, we address some of the most commonly asked questions about king-size mattresses and buying one.

    How Much Is a King Mattress Worth Today?

    The price range of a king-size mattress is between $500 and $5,000, depending on the materials and features. Here’s a quick breakdown recap to help:

    • Budget-Friendly ($500–$1,000). Basic foam or innerspring options are great for shoppers on a budget.
    • Mid-Range ($1,000–$2,000). You’ll find memory foam and hybrid models that offer excellent support and durability.
    • Luxury ($2,000+). This includes premium materials like organic latex, advanced cooling features, or adjustable firmness for a customized experience.

    Why Is King Size So Expensive?

    It all comes down to size and quality. A king mattress requires more materials, whether foam, coils, or fabric. Higher-end options may also include features like cooling gels or advanced support systems for spinal alignment, which impact the price. Factor in manufacturing and shipping costs, and the price makes sense.

    How Often Should You Replace Your Mattress?

    Most mattresses last 7 to 10 years, which can also vary by type. With memory foam, you can expect to replace it in 8 to 10 years. Latex can stay in perfect condition for longer, and you should replace it every 10 to 12 years (natural latex outlasts synthetic blends). The innerspring usually lasts the least, and you can expect to shop for a replacement in 7 to 8 years, as coils tend to wear out faster.

    To keep yours in top shape, rotate it every 3–6 months and use a mattress protector to guard against spills and dust mites. When you notice sagging, lumps, or poor sleep, it’s time to upgrade.

    Is It Worth Going From a Double to a King Size Bed?

    If you have the space, absolutely. A king-size provides nearly 20 extra inches of width compared to a double mattress, giving you and your partner more personal space. It’s also perfect if you share a bed with kids or pets.

    How Long Should a King-Size Mattress Last?

    It’s tricky to state precisely a mattress’s lifespan, but we can play with numbers and approximate: Memory Foam mattresses typically last at least 8 years, though higher-quality foam may last longer. Known for their durability, latex mattresses can typically last for at least 10 years. As for innerspring, coils typically lose their support over time, especially if not properly maintained. A rough estimate is that they should last for at least 7 years.

    How Much Is a King-Size Mattress? Final Thoughts

    A king-size mattress can be a game-changer for comfortable, restful sleep, but you need to think about everything when choosing yours. From material quality to features, the prices of a king-size mattress will largely depend on your preferences.

    Explore different king-size mattress options, do research about them, and test them yourself to find the perfect one for your family. Sweet dreams!
