For camping use, we found the best ratings for the Coleman Single High Quickbed Airbed, available in sizes from twin (Est. $20) to king (Est. $35). Most users say that this super-inexpensive mattress is an amazing value: comfortable, easy to inflate and deflate and very good at retaining air. They also like the built-in carrier, which makes it easier to transport the mattress. One major caveat is that this mattress doesn't come with a pump. Coleman offers several compatible models -- from the $20 QuickPump Hand Pump Dual Action Inflation System to the $30 Rechargeable QuickPump -- but adding one will roughly double the cost of the mattress. The other downside of this mattress is durability; reviews indicate that its typical lifespan is three months to a year. The mattress does have a one-year warranty, but shipping costs aren't covered, making it nearly as cheap to buy a new one.
Coleman also offers the versatile Coleman 4-N-1 Quickbed Airbed (Est. $45) . This air mattress can be used as two separate twin beds, zipped together to make one king-size mattress, or stacked and snapped together for one double-high twin mattress. Like the Coleman Single High Quickbed Airbed, it comes with a built-in carrying bag but does not include a pump. Users find this mattress comfortable and easy to inflate, and they say it holds its air well. As with the other Coleman mattress, its chief problem is durability. Many reviews say that one of the two twin mattresses either had a leak when purchased or developed one soon afterward.
We also found reasonably good reviews for the Intex Supreme Air-Flow ($65 and up). The manufacturer bills this as an indoor air mattress, and its built-in pump is designed for use with a standard electric socket. However, Cabelas.com, a major retailer of outdoor supplies, offers it for camping use, and some users say it works fine for this purpose with the addition of an inverter to hook it up to a car battery. The Intex Supreme's biggest plus is comfort; many users find this double-height air mattress so comfortable that they use it as a permanent bed. Most owners also find it easy to inflate and deflate. However, reviews are split on how airtight the mattress is. While most reviews say it holds air well, we saw many that complain of leaks, especially along the seams. Moreover, this airbed is not backed by a warranty.
