10 Best King Size Blow Up Mattresses 2026 in the United States

The King Koil Premium California King Size Air Mattress stands out with its impressive comfort features and convenience. Made from durable, puncture-resistant materials, it is designed to last. The mattress includes a soft flocking layer and a built-in pillow, providing additional support and comfort, which is a big plus for those who prioritize a good night's sleep. The built-in, high-speed pump can inflate the mattress in under three minutes, making setup and takedown quick and easy.

It features adjustable firmness, allowing you to find your perfect comfort level, and supports up to 650 pounds, catering well to different body types and sleeping positions. These features make it an excellent option for home use, camping trips, or accommodating guests. Additionally, it comes with a 1-year warranty, showcasing the manufacturer's confidence in the product’s quality and their commitment to customer satisfaction.

However, the mattress’s size and weight might make it less portable than smaller options, which could be a drawback if you plan on moving it around frequently. Lastly, while the built-in pump is very convenient, its reliance on AC power means you'll need an outlet nearby to inflate it, which might limit its use in more remote camping locations. In summary, this air mattress is perfect for those seeking comfort and convenience in both home and travel settings, provided you have access to power for inflation.

The SoundAsleep Dream Series Luxury Air Mattress is a king-size, double-height blow-up mattress designed for both home and camping use. It stands out with its ComfortCoil Technology and SureGrip bottom, offering enhanced firmness and stability with 48 internal air coils.

The mattress ensures a comfortable sleep experience thanks to its extra-thick, waterproof flocked top and durable, puncture-resistant PVC material. The built-in, patented 1-click internal pump allows for quick and easy inflation and deflation, taking less than 4 minutes to fully inflate. This mattress is substantial, with dimensions of 84” x 72” x 19” and can comfortably support multiple people or a single person luxuriously. It weighs 23.2 pounds, making it relatively portable with the included carry bag, although its size may make it less convenient for some users to transport.

The customer-friendly 1-year warranty and US-based support offer peace of mind. While the mattress is highly rated and designed for comfort and durability, its size and weight may not suit everyone's portability needs. Additionally, some users might find the need for occasional top-ups with the pump to maintain firmness. It remains a solid option for those seeking a reliable and luxurious inflatable mattress.

The EnerPlex King Air Mattress is a solid choice if you want a large, comfortable inflatable bed for camping or home use. Made from durable PVC, it’s built to last and withstand regular use. Its size is true king-size, measuring 80 by 76 inches, and with a height of 18 inches, it offers a thicker, more supportive feel compared to thinner mattresses. The mattress comes with a built-in pump, which makes inflation quick and hassle-free, saving you the effort of using a separate pump. This feature is especially handy if you’re setting up at a campsite or for guests at home.

It’s firm in feel, which many people find supportive, though if you prefer a softer mattress, you might need to add extra bedding. Weight-wise, it’s fairly heavy at over 10 kilograms, so while it’s portable, it might be a bit bulky for frequent backpacking trips but fine for car camping or travel where space isn’t super tight. Storage is reasonable since it deflates and folds down, but due to its size and weight, it’s best suited for those who don’t need to move it very often. Customer reviews are generally positive, praising its comfort and durability.

Care instructions recommend hand washing, which means it needs gentle cleaning to keep it in good shape. The mattress includes an adapter for the pump, making setup easy. The EnerPlex King provides a firm, spacious, and easy-to-inflate solution mainly suited for home use or casual camping, with portability that’s decent but not ultra-light.
