1. After inflation with the standard built-in compressor for cheap air beds (really always the same device) keeps the bed its hardness for about 2 hours. After this time, the pressure has dropped to a default value, which keeps the bed in an unhealthy banana shape. The compressor is a known air leakage in these beds, also extremely noisy and quite inefficient.
2. The left side of the bed is softer and deeper than the right side, as if the advertised stiffening, which should allow a sitting on the bed, was not installed on the left.
3 On the right side is a seam after 2 nights burst that generates these beads on the bed edges.
4. According to another use is above seam has completely adopted.
5. # 4 was the last night, in which the "bed" its air overnight as far held that not folded wakes up on the floor. In other words, there is considerable leakage has formed, as well as in half of the other reviews. Why Amazon these disposable beds still being sold is a mystery to me.
I can not imagine how one can get the idea that would allow such a bed good night's sleep. This is an ergonomic maximum accident that borders on assault. Do not be fooled by the rectangular shape on the product image and the older guests are, the more you should look for something else.
Conclusion: Due to the abysmal quality and workmanship there is only one star because 0 stars are not possible. For the same price is often a nice hotel room to book with a real bed, what can the guests to spare pain.
