(Top 4) Best “King Size” Air Mattresses To Buy Online: Tested & Reviewed


King size air mattresses provide a comfortable and spacious sleeping solution, whether you’re hosting overnight guests, going on a camping trip, or need a temporary bed. To help you make an informed decision, we’ve compiled this comprehensive buyer’s guide featuring the best king size air mattresses available online, complete with descriptions and pros and cons based on customer reviews.

What to Consider Before Buying

Comfort and Support:

A comfortable and supportive air mattress is crucial for a good night’s sleep. Look for features such as flocked or quilted tops for added comfort, internal coil systems for improved support, and adjustable firmness to cater to your personal preferences.

Inflation and Deflation:

Effortless inflation and deflation are essential for convenience and easy setup. Some air mattresses come with built-in electric pumps, while others require external pumps. Built-in pumps are typically faster and more convenient but can add to the overall weight of the mattress.

Material and Durability:

Opt for an air mattress made of puncture-resistant and waterproof materials, such as PVC or TPU. A thicker material usually provides better durability, but it may also increase the weight of the mattress. Look for air mattresses with reinforced seams and airtight valves to prevent air leaks.

Height and Thickness:

Air mattresses come in various heights and thicknesses, with raised options offering a more bed-like experience. A higher air mattress is usually more comfortable and easier to get in and out of but may be more challenging to transport and set up.

Portability and Storage:

If you plan on using your air mattress for camping or traveling, consider its portability and ease of storage. Lightweight air mattresses with carrying bags or compact storage options are more convenient for travel.

Weight Capacity:

Ensure the air mattress you choose can accommodate the combined weight of its users. Most king size air mattresses have a weight capacity of around 600 lbs, but it’s essential to verify this information before purchasing.

Warranty and Customer Support:

A good warranty and responsive customer support are crucial when investing in an air mattress. Look for brands that offer warranties and have a reputation for excellent customer service to ensure you’re covered in case of any issues.

Price and Value for Money:

King size air mattresses can range from budget-friendly options to premium models. Determine your budget and consider the mattress’s features, durability, and comfort when deciding if it offers good value for money.

By considering these factors, you can make an informed decision when purchasing a king size air mattress that best suits your needs and preferences. Don’t forget to read customer reviews and research each product thoroughly before making a purchase to ensure you get the perfect air mattress for a comfortable night’s sleep.

King size air mattresses usually measure approximately 76 inches wide by 80 inches long, which is the same as the standard dimensions for a regular king size mattress. However, the height of air mattresses can vary significantly depending on the design and features. There are three common height categories for king size air mattresses:


These air mattresses have a height of around 5 to 9 inches. They are lightweight and compact, making them suitable for camping and easy storage but may be less comfortable than taller options.


With heights ranging from 10 to 18 inches, mid-rise air mattresses provide a more comfortable sleeping surface without being too bulky. They are a popular choice for both indoor and outdoor use.


High-rise air mattresses typically measure 19 to 25 inches in height, offering a bed-like experience and easier access. They are ideal for indoor use and provide the most comfort but may be less portable and more challenging to set up.

Typical Pricing for a King Size Air Mattress:

The price of a king size air mattress can vary significantly depending on the materials, features, and brand. Here’s a general breakdown of the pricing ranges you may encounter:


King size air mattresses in the “Budget Friendly” category typically cost between $50 and $100.

Mid-range king size air mattresses are priced between $100 and $200.

These mattresses usually offer a better balance between comfort, durability, and features, such as built-in pumps and flocked tops. They are suitable for more frequent use and offer better value for money.


Premium king size air mattresses can range from $200 to $500 or more.

These high-end options often come with advanced features like adjustable firmness, reinforced construction, and luxury materials. They provide the highest level of comfort and support but may not be necessary for everyone.

When shopping for a king size air mattress, it’s essential to consider your specific needs, preferences, and budget. Keep in mind that spending a bit more on a higher-quality air mattress may be a better long-term investment, especially if you plan on using it frequently.

The Different Styles and Their Uses:

Air mattresses come in various styles and designs, each with their unique features and advantages. Here are the different kinds of air mattresses and their popular uses:

Single-height air mattresses:

These air mattresses are typically 5 to 9 inches high and are lightweight and compact. They are easy to transport, making them perfect for camping trips, hiking, and other outdoor activities where space and weight are critical. Single-height air mattresses are also suitable for occasional overnight guests in a home setting.

Double-height air mattresses:

Double-height air mattresses are taller, usually between 10 to 18 inches in height. They provide more comfort than single-height mattresses, making them suitable for both indoor and outdoor use. These mattresses are ideal for temporary sleeping arrangements, such as accommodating guests in your home, college dorms, or during a move.

Raised air mattresses:

These air mattresses are the tallest option, typically between 19 to 25 inches in height. They provide a bed-like experience and are easier to get in and out of, making them ideal for long-term use or elderly guests. Raised air mattresses are more suitable for indoor use, such as in spare bedrooms or as a temporary bed during home renovations.

Self-inflating air mattresses:

Self-inflating air mattresses are made of open-cell foam sandwiched between two layers of fabric. They are designed to inflate automatically when the valve is opened, making them convenient and hassle-free. These mattresses are popular for camping trips and other outdoor activities where a comfortable sleeping surface is desired.

Air mattresses with built-in pumps:

These air mattresses come with integrated electric or battery-operated pumps, providing quick and easy inflation and deflation. They are perfect for home use, especially for those who host guests frequently or need a temporary bed for themselves. Some models even offer adjustable firmness for customized comfort.

Airbeds with adjustable air chambers:

These high-end air mattresses feature separate air chambers that can be adjusted to control the firmness and support level on each side of the bed. This design allows couples to customize their sleeping experience according to their preferences. These luxurious airbeds are suitable for long-term use in place of a traditional mattress.

In summary, the type of air mattress you choose depends on your intended use, comfort preferences, and budget. Consider the features and advantages of each kind to find the best option for your specific needs.
