  • Super Comfortable and Perfect During a Move
I bought this air mattress right when I was moving, and since I’m pregnant, comfort was really important to me. I was honestly very surprised by how comfortable it was, and I have absolutely no complaints. It’s very easy to inflate thanks to the built-in pump, has a great height, and feels sturdy and spacious. It helped me so much during the move, and I would definitely buy it again. ... show more

  • Great hold and comfortable
So far so good, I got the king size mattress and it is the perfect size for my bed hog husband, my two year old and I to lay in pretty comfortably. It provides a sturdy hold all night with no need to inflate through out the night. Suitable for more than two guests and didn’t seem to have any leaks. It sits more on the firm side so if you like a firm bed this is for you. ... show more

  • No sqeaks, rustling or noise, very comfy and easy to inflate...just watch the size
I love this mattress, for the price and the quality I don't know if it can be beat! There is absolutely no noise getting on and off (mine was temporarily on carpeting until my platform bed came today). I added a two inch latex topper to it which I already had, which added an extra layer of comfort. On the floor it was great, like a sleep number bed, once my topper was added. The velour surrounding it is awesome. Sheets cling to it very nicely! The size referenced in the ad 72x80x18 is pretty much spot on. A standard king is 76x80. I was hoping that the 4" wouldn't make a difference but it is quite a lot once I put the airbed on the platform (another reviewer suggested that if you are putting the airbed on a platform to use the cardboard from the packaging and once cut to size, put it on the platform slats, which I did and it seems to work great). I would probably be happy with it on my platform bed if I hadn't ordered one that is a full 18" tall. I pretty much have to climb up on the bed, so even though it is only 4" short (2" on each side), I decided I need to go with about a 10" airbed. Since I took a chance on this size, I'm not going to return it. It wouldn't be fair. They would probably have to throw it out due to Covid (that's what Big Lots does - toss the returns). So I'll keep the 18" mattress for my spare room. If it was shoddy mattress, I would return it, I took my chances with the size. I recommend this mattress. Remember inflate, deflate, inflate again and deflate maybe once more so it stretches a bit. You may have to add air every three days or so, but it's worth it. Not much air, just a little due to temperature changes etc. Maybe in another week it will settle into it's "happy spot" and added air won't be needed. It's so easy to add, I don't know why people complain. Intex is a good brand -- they have been around a long time! So now I'm off hunting down a 10-12 inch for my platform bed. Hope this review helps! =) ... show more

  • Followed Instructions, Still Deflates
Very disappointed with this air mattress. I followed all of the instructions for inflating it, including allowing the material to stretch as recommended, but it still won’t hold air for a full night. I made sure the valve was completely closed, yet I wake up on the floor every morning and have to reinflate it. It completely defeats the purpose of an air mattress. I expected much better quality and would not recommend this product. ... show more

  • Good air mattress that lasted a while
I bought this air mattress in June 2024, and it was a really great air mattress for the most part. I used it as my bed and kept it inflated for as long as I could. It inflates pretty well, within less than five minutes. It was pretty comfortable; firm, yet comfortable enough to sleep on every night. It lasted me a year and four months before it finally gave out. I suspect there is a hole somewhere that is causing a leak. I had noticed over the year I've had this mattress that every 1-3 months, it would start to deflate enough that I needed to give it a quick inflate (about a minute at most). It would hold the air from there. There were only two times that I found it deflating, and found that the pump dial had turned to deflate. That probably happened from being up against a wall -- my tossing and turning probably pushed the dial against the wall and somehow turned it enough to cause it to audibly deflate suddenly. However, that only occurred twice, and hadn't been a problem since the last time it happened. Overall, this air mattress was great and lasted a good while. I now have to buy an air mattress with a sturdier material, in hopes of the new one lasting longer. I'd say this is a good air mattress to buy, but, just be careful of anything that could cause a tear or hole (even friction from movement on a hardwood floor might affect it over time). You'll get a good night's sleep on this as long as it lasts and is properly inflated. EDIT: I found the hole where the air is leaking out. It's a tiny hole on the side of the mattress. It's not on a seam, but, it's very close to a seam. Something might have punctured it or the material gave out, hard to know. ... show more

  • comfortable
Very comfortable. Just keep in mind if camping, the built in pump has to plug in to power. Because it was a high bed, we did not feel the cold ground when camping like my friends did with their shorter mattresses.
