The biggest advantage of the Coleman 4-N-1 Quickbed Airbed is its versatility. It can convert from two twin mattresses to a king or a double-height twin, so it works in a variety of situations. Users also say it's comfortable and easy to use, though they do have a few durability complaints. Its weakest point is the lack of a pump, but at $45, you can add one without breaking the bank.
Bring your own pump. Like other Coleman mattresses, the 4-N-1 Quickbed Airbed doesn't come with its own pump. However, any Coleman pump -- manual, electric or battery powered -- should work with its double-lock valve, and pumps from other manufacturers will fit with an adapter. Users generally find the mattress easy to inflate and deflate, regardless of the type of pump. They say the double-lock valve is a useful feature, as it keeps air from leaking out after inflation but lets it all out quickly during deflation. Afterward, the mattress rolls up neatly into its own built-in carrying bag.
Comfort level varies. Reviews suggest that the comfort level of this mattress depends on the configuration. When stacked to make a double-height twin bed, it's quite comfortable, but the individual twin mattresses are only as comfortable as you'd expect for an air mattress. Some users say the king-size mattress is actually the least comfortable, as there is a noticeable gap between the two halves. A couple of reviews recommend covering this extra space with a blanket, or even stuffing blankets into the crack. Another owner says that a "really supportive pillow" is a must with this mattress.
Watch out for leaks. Like other Coleman mattresses, this one receives mixed durability reviews. Users generally agree that it holds air very well as long as the mattress is intact, but there are also quite a few complaints about holes or gaps in mattresses that are brand new or nearly new. Usually only one of the two twin mattresses is affected, but this eliminates most of the mattress's utility. One owner recommends testing both mattresses immediately after purchase and being prepared to return them if one is defective. Another recommends buying a bottle of vinyl-patching solution, as "the chances of having to repair it are huge."
The author, a camping enthusiast, reviews and recommends air mattresses based on her family's experience. She declares the Coleman 4-N-1 Quickbed Airbed "the best bargain I've ever got for air mattresses," because it's so versatile. She also says it holds air well, but that it's not as comfortable as a real bed.

In over 125 reviews, the Coleman 4-N-1 Quickbed Airbed earns an overall rating of 4.2 stars out of 5. Owners praise the airbed's versatility, comfort and ease of use, but we saw many complaints that one of the two mattresses leaked -- either right out of the box or shortly after purchase.
