Review: Best camping mattress we’ve ever used! - This foam-filled air mattress completely changed our camping experience. It is extremely comfortable, well insulated, and surprisingly doesn’t sleep hot like some foam mattresses can. We woke up feeling like we had slept on a real bed rather than an air mattress. The biggest difference is the foam filling. It provides much better support and doesn’t have that “bouncy” feeling you get with a traditional inflatable mattress. The rechargeable pump is another huge plus. It inflates the mattress quickly and makes deflating it just as easy when it’s time to pack up. No struggling with a manual pump or trying to squeeze all the air out by hand. We use it in the back of our SUV, and it fits our setup perfectly. After sleeping on this, we will never go back to a traditional inflatable air mattress for camping. It’s comfortable, supportive, insulated, and incredibly convenient. If you’re looking for a comfortable car-camping mattress, I highly recommend this one. It’s worth every penny!
Review: Would I recommend them? Absolutely. - We bought these to supplement what are supposed to pass as a mattresses in our pop up camper. I wouldn't say they solve any problems (hubby and I both have injuries and some issues). But they are certainly comfortable and no complaints from us. WAY better than whatever the foam pad is that came with the pop up. ----> Although! We use these mattresses on top of those foam things. We deflate them and leave them in the pop up. They deflate flat enough that closing the camper is not an issue. I haven't attempted to deflate them and roll them up and stuff them in those storage bags. However, once they're deflated they do seem like they wouldn't be *terribly* difficult to manipulate. It might take two people tho. They're bulky but not exactly heavy when they're inflated or deflated (not counting the potential rolled up aspect). Plenty of cushion for our camping trips. Durable enough we could take them outside if we wanted to. They each came with their own air pump for inflating and deflating. However, when I opened the valve the mattresses just puffed right up. I didn't need the pump. And using the pump to deflate them takes just a few minutes. Remember to charge them up before you head out the door. Ours were fully charged at the end of our last camping trip and had no charge at all when we tried to use them on the recent one (about a 7 week window). Fortunately with our pop up, we just plugged them in with no further issue. I've only ever had air mattresses that are 1/10th percent better than a pool float. That's my comparison; I have never tried a different product similar to this one. So, I do think these were a bit pricey but worth it. Would I recommend them? Absolutely.

### ⭐⭐⭐⭐⭐ Affordable and comfortable
*by J***. on July 15, 2026*

I initially wanted to purchase an Exped, but the price point was too high. This was at half the price plus you get a thicker mattress. My wife and I preferred using it with the least air and practically all foam, with both of us on the mattress the little air inside compressed enough to allow enough firmness for support and the foam gave enough cushion for a good night's sleep. It took 3 nights of camping to figure this out, but we know what we like on our next trip. It's easy to setup. Unpack and open the vent to allow it to self-inflate which takes less than 5 minutes, then adjust the air to your liking. High quality for sure!!!
