I'm so impressed with the quality and comfort of this air mattress. After my old air mattress had a leak, I did some research on what to buy next and I found King Koil. I've told everyone I know, I'm never buying anything but King Koil!
Purchased for my daughter to be able to use for having friends at the house. It inflates quickly and worked well for the couple of uses it has had so far. The 1-year warranty is fantastic too!
Fantastic air mattress. If I could give this 6 stars I would! It is very comfortable. We have guests over often and they absolutely love sleeping on the California King size!
I purchased the King Koil air mattress and have been very satisfied. It's comfortable, easy to inflate/deflate, and has held up well. Highly recommend for a comfortable, reliable temporary sleeping solution.
Yes. King Koil's patented coil-beam construction is engineered specifically to maintain firmness overnight. Unlike basic air mattresses that soften as you sleep, ours holds its shape from when you inflate it to when you wake up.
What sizes does King Koil come in?
King Koil air mattresses are available in Twin, Full, Queen, and California King - each in your choice of 13", 16", or 20" raised height profiles. The 20" is our most popular, sitting at the same height as a traditional bed frame and making it easy to get in and out of. We also offer a dedicated kids/ toddler size, designed lower to the ground with safety in mind. Whatever your situation: guest room, camping trip, or a sleepover setup for the kids, there's a King Koil built for it.
Still unsure? Consider your space, how many people will use the bed, and how portable you need it to be.
Yes, the King Koil air mattress is designed to provide maximum comfort and support while you sleep. The mattress features a soft flocked top layer and a durable coil beam construction that helps distribute your weight evenly.
Most air mattresses are essentially inflatable pool floats made from thin material, basic construction, and they lose air by morning. King Koil uses patented coil-beam support, heavy-gauge puncture-resistant material, and a patented, built-in pump engineered for longevity.
