Very good
Style: 18", Color: Grey, Size: Queen
I recently purchased this inflatable mattress from Amazon, and I’m honestly very impressed with the quality and comfort. It inflated quickly and was very easy to set up. The material feels durable and strong, and the mattress stayed fully inflated throughout the entire night without losing a

This is a very good air mattress
Style: 13”, Color: Grey, Size: Twin
I love this mattress so much I work overnights and I needed something to sleep on so I bought this mattress and it was the best mattress ever it’s so comfortable I purchased it Dec 24th2025 and it’s now starting to deflate I can’t find any holes in it but I still use it. I’m not gonna get rid of it because I can still sleep on it I just need to inflate it two times throughout the night it doesn’t bother me because it’s so comfortable. I’m not gonna lie I did purchase another one. But I’m 125 lb but the grands can sleep on it when they stay over so I will be keeping it. This is a really good air mattress well worth your money.

Decent air mattress if you take care of it
Style: 22", Color: Grey, Size: Queen
I’ve been buying this air mattress, and its previous model, for the last four years. I used to go camping and attend festivals about six times a year, and I wasn’t particularly nice to my air beds. Most of the time I didn’t fold them back up neatly or put them in the storage bag. I’d just deflate them, throw them in the car, and head to the next event. Even with that treatment, they held up surprisingly well.
I was nervous about buying the new version with the redesigned inflate/deflate module, but on a whim I decided to give it a try.
I used it during a five-night camping trip near Tygh Valley, Oregon at the end of May 2026, where temperatures ranged from about 85°F during the day to around 40°F at night.
Did it lose some air over the weekend? Yes. Was it enough to bother me? No. In fact, over the entire five-night trip, I only had to add air once. Considering the temperature swings, I was impressed with how well it held up.
The new model does seem to take a little longer to deflate than the older versions, but that’s a minor complaint. Overall, I’m very happy with it.
I’ve had good luck with these mattresses over the years, and this new version seems just as solid as the previous model.
I would absolutely recommend this mattress and will continue buying this model when it’s time to replace mine.

Better than our actual mattress!!
Style: 22", Color: Grey, Size: Queen, Style: 22", Color: Grey, Size: Queen
Purchased for company to stay with us in our apartment. I honestly had no idea they made air mattresses this tall until I saw a friend with one!
My husband and I tested it out last night. We were both really impressed!
1. Really easy to inflate! First time having an internal air pump. No more forgetting the pump! The motor wasn’t nearly as loud as our previous air pump! I was able to talk to my husband and he could still hear me over the pump running.
2. Really comfortable and supportive! We chose not to inflate it fully so it contoured to our bodies better. We slept on the mattress with no sheets and I wasn’t able to feel the creases in the top which was nice. No issues with sagging and we both didn’t wake up smooshed in the middle. My husband got up in the middle of the night and I didn’t notice. So movement of the mattress is minimal! Easy to get on and off with the 22” height.
3. Easy to deflate! We followed the instructions for folding and we got it in the storage bag with no issues. Just make sure all of the air is out before you fold it.
4. High quality! We had both of our small dogs on this with us. I was afraid of their nails poking a hole but so far so good! Only a little bit of air leaked out but it could’ve been the material stretching out during the night.
Cons: The pump does not shut off automatically when inflating or deflating. So keep an eye on it so it doesn’t overfill. The mattress does get cold at night. My husband and I both mentioned that in the morning. I had to roll up in my blanket to stay warm. I’ll try sheets on next time. In the summer it might not be that big of an issue. Ours came with one patch. Hopefully we won’t need to use it.

Excellent pillow
Size: King Size Pack of 1, Color: White
This is a great pillow!! I ordered this for my elderly mother who wanted a softer pillow. She absolutely loves this one. It’s supportive, keeps her cool also keeps its shape. I love that it came with extra stuffing so you can customize it. Well worth the price!!
