A king size innerspring mattress is a great choice for those who want to upgrade their sleep game. These mattresses offer excellent support and pressure relief, making them perfect for couples or individuals who value their comfort.
King size innerspring mattresses typically range in thickness from 10 to 14 inches, with some models offering up to 18 inches of depth. This thickness provides ample support for the spine and promotes a restful night's sleep.
Innerspring mattresses feature a coil support system, which is designed to provide excellent edge support and prevent the mattress from sagging over time. This is especially important for king size mattresses, which can be more prone to edge sagging due to their larger size.
With so many options available, selecting the right king size innerspring mattress can be overwhelming. However, by considering factors such as coil gauge, mattress material, and warranty, you can make an informed decision that meets your needs and budget.

What to Know
A king size innerspring mattress is a significant investment, and there are a few things you should know before making a purchase.
King size mattresses are designed to provide extra comfort and support for taller individuals or couples who share a bed. They're typically 76 inches wide and 80 inches long, offering 16 square feet more surface area than a standard queen size mattress.
A good innerspring mattress should have a thick enough comfort layer to provide adequate support and pressure relief. This typically ranges from 10 to 14 inches in depth.
Innerspring mattresses often feature a coil-on-coil design, where multiple layers of coils work together to provide support and pressure relief. This design can help to reduce motion transfer and promote a restful night's sleep.
It's essential to consider the weight capacity of your mattress, especially if you have a larger partner or plan to add a mattress topper. A king size innerspring mattress can support up to 400 pounds, depending on the manufacturer and model.
Ultimately, the right king size innerspring mattress for you will depend on your personal preferences and needs.

One type of mattress that stands out for its durability and versatility is the innerspring mattress, particularly those that are flippable. These mattresses often feature individually wrapped pocketed springs, like those found in Simmons Beautyrest mattresses, which provide exceptional support and promote spinal alignment.
A flippable mattress allows you to switch between two different firmness levels, giving you the flexibility to adjust to your changing needs over time. For example, if you prefer a softer surface for extra pressure relief, you can flip the mattress to its softer side.
Many innerspring mattresses, including those from Sealy, feature innovative technologies like Posturepedic, which deliver superior core support and promote a cooler night's sleep due to excellent airflow.

We've recently evaluated 26 innerspring mattress models, sending them to hundreds of consumer testers to review at home. This gives us a comprehensive understanding of how they perform in real-world conditions.
Our Selection and Testing Process
We've done our research to help you make an informed decision when shopping for an innerspring mattress. We listened to readers and dug into online forums to learn about the mattresses people are curious about. We narrowed down the field to 12 brands and asked each company to recommend a model with wide appeal.

To make our picks, we considered several key factors, including quality materials, decent edge support, and adequate motion isolation. We looked for mattresses with at least 400 to 500 support coils and polyfoam densities of around 1.5 pounds per cubic foot.
We also considered the importance of a good warranty, with a minimum of 10 years of coverage. We weren't impressed by warranties longer than that, as companies can often find reasons to avoid honoring them. Here's a breakdown of our key considerations:
- Quality materials: coil counts of at least 400 to 500 support coils and polyfoam densities of around 1.5 pounds per cubic foot
- Decent edge support: the ability to sleep on the mattress without fear of rolling off the edge
- Adequate motion isolation: the ability to minimize movement with pocketed coils and foam layers
- At least a 10-year warranty: a standard length of coverage
- Reasonable return policy: a recourse for unhappy customers
We also put each of the top contenders through a rigorous testing process, including in-office testing, home testing, and owner reviews. We anonymously emailed, called, or live-chatted with each company's customer service to gauge their speed and helpfulness. We surveyed over 10,000 readers on our GH survey panel and sent hundreds of mattresses to consumer testers to review at home.
Shopping for a Mattress
Shopping for a mattress can be overwhelming, but knowing what to look for can make all the difference. Innerspring mattresses come in different firmness levels, and mattress makers often offer exclusive designs to different stores.
To find the right mattress, consider the quality of materials used. A minimum of 400 to 500 support coils and polyfoam densities of around 1.5 pounds per cubic foot are recommended to prevent sagging and body impressions.
Decent edge support is also crucial. You want to be able to sleep on a mattress without fear of rolling off the edge. Look for mattresses with a perimeter that allows you to sit on it without sliding off.
Innerspring mattresses don't isolate motion as well as foam mattresses do, but pocketed coils and foam layers can minimize movement. Consider mattresses with these features if you share a bed with a partner.
A 10-year warranty is a good starting point. While longer warranties may be available, they may not always be enforceable. Be sure to read the fine print.
If you're not satisfied with your mattress, a reasonable return policy is essential. Look for companies that offer free trials and returns, or at least provide a recourse if you're unhappy with your purchase.
To get a feel for a mattress, it's essential to lie on it and test it out. Spend several minutes to several hours lying on each mattress to get a sense of its feel and function.
