King Koil Luxury Queen Size Air Mattress with Built-in High-Speed Pump, 20″ Adjustable Double High Premium Pillow Top Inflatable Airbed for Guests, Camping & Home (Manufacturer Warranty)

I slept on this mattress every night for two years and three months (Nov. 2020 – Dec. 2022 then again Feb. 2024 – April 2024). About to order another one, as I recently had to roll it up for good. I believe an error on my end caused it to develop a bulge and leak air, not a mattress defect. Basically, with it lasting so long, I got over-confident and over-inflated it a couple of times, maybe three.As my main bed, i have a lot of praise for this puppy, and really only three drawbacks, one of which is just the nature of an air mattress. Lets start with the drawbacks:1) When it began to leak air, I called customer service for technical assistance to troubleshoot the leak. Well, the guy refused to continue speaking or even listen to me since my mattress was out of warranty.So…hmmm. But, if the mattress was in warranty, I’m sure their customer service is perfectly fine. I assume this because they do have a fine product and probably stand behind its quality. That’s just good business unlike the customer service I received.2) Air mattresses naturally have these pocket dips, if you will. Because I didn’t want to purchase a mattress topper, I just padded it with my spare comforter. Worked pretty darn well!3) biggest drawback and keep in mind, I purchased mine Nov. 2020, so this feature may not be on the mattress now in Aug. 2024. Idk. But…It had this large hump to keep your pillow from slipping off the edge and onto the floor. Great idea. But my queen fitted sheet wouldn’t fit on the mattress due to this hump. Not even close. I had to buy a king fitted sheet.Now, this ended up being a good thing because the king fitted sheet covered both sides (not ends, just sides) of the bed all the way down to the floor. This protected the siding a bit in my opinion.Another unexpected “this-is-ok” about the hump was that it somewhat felt…headboard-ish…which is nice if you’re used to a normal bed frame and mattress.Let’s move to the good stuff:1) I like a firm mattress. Check – it is a very comfortable firm.2) I sleep in all positions, but mainly a side sleeper. Check. Support was good for my lower back. Shoulder did not hurt in the morning. Lower back would hurt occasionally if I slept on my back too much, but for me…that’s the norm no matter what mattress I sleep on. When I flip onto my stomach, it’s comfy due to the mattress having just enough give. Keep in mind, I also padded it a bit with a comforter under my fitted sheet.3) For the first 2-3 weeks of owning it, I had to add about 5 seconds of air to it every 5-7 nights…probably due to it adjusting to its shape and newness. After that, I’d add maybe 5 seconds worth of air every 2-3 weeks. No biggie. But it was important not to add too much and overinflated. I was very careful about this…up until I got complacent and went beyond 10 seconds in one go (which as I said earlier, I think that’s why it developed a bulge and therefore a leak that I could never find.).4) All sides are flocked. My fitted sheet would rise up a bit, but not too bad. I’m guessing if the sides where the smooth type, they would have risen up a lot.5) the edges didn’t sink a whole lot. When they began to get a bit squishy, that’s when I knew my mattress needed an air top-off of about 5 seconds.6) So as to not over-inflate and ruin my mattress, I felt the mattress after 5 seconds when I’d top it off. This was usually enough. It fills up quickly. If you need to go beyond 5 seconds, I recommend doing so in 3 second intervals after those first 5 seconds. Remember, once it reaches firm, it’s at capacity and you must stop. Continuing to fill it could bust the inside coils.7) Thickness: it’s 20” off the ground. I’m a 125 lb; 5 foot, three inch female. Not too shabby to get out of bed comfortably.8) It really has a lovely, elegant appearance. With sheets on, no one knows that, but still…it does speak to the care put into the product from the manufacturer.9) the bag is nice. I used it twice in the two years of this being my only bed. I made the bed fit in there again, after two attempts to roll it to bag size.10) It will sleep two people just like a traditional queen mattress. My feet sometimes hung off the end just a bit, but I also tend to sleep low in a bed (head not all the way at top). The hump at the top takes up some of the length, so if you’re a 6 foot dude, your feet may hang off a bit if you’re stretched out, but it’s really a small issue with how nice the bed is.So, my bed finally pooped out, but again, I think it was my own error. I was really happy with my bed and bummed when it bit the dust, so… I’m going to give these folks my business again and order a new one. I bet I’ll get another 2-3 years out of it.
