  • What a life saver!
    Verified Purchase

    This is a great set of air mattresses. The versatility of the configurations was definitely a plus. We have used them as a king sized bed, two twin beds and as a stacked twin bed. They were very easy to inflate and stayed inflated incredibly well. We have used other air mattresses that seem to soften and lose inflation as you sleep. In fact, these are so comfortable that we used them (as a stacked set) against a wall in a living room until a new couch arrived.

  • Good Product, Still Going Strong!
    Verified Purchase

    We purchased two of these Airbeds and they are both still in great shape. We use them whenever we need extra beds for visitors. They don't leak and are quite sturdy and nice. No one has complained about their comfort so I consider them a great buy.

  • Material is plasticy.Stacking on top very unstable
    Verified Purchase

    I ordered this and tested it. I slept with each stack up as a single bed. It feels unstable and got a sailing effect- wobbly and edges seems to fall out. The material is har and plastic feel to it. One of it seems to be leaking after 3 hrs on it. Not a good experience at all. I am returning it.

  • Nice spare bed
    Verified Purchase

    A good option for a spare bed for guests. Inflates and deflates very quickly. Our guest said it was comfortable; haven't yet tried it myself but seems like it would be comfortable. One of the best features, for us, is that this particular set may be used in a few different ways; two singles, one king, one double-decker single. Lots of options for the price. We set it up as a king for our guest; we used a fitted mattress pad to keep the two separate pieces together. Our guest said the space between the two mattresses was definitely noticeable; however this did not really affect his comfort. We would recommend this airbed.
