Electric air pump can be filled in 50-150 seconds (mattress, bed generally takes about 2 minutes). Non-built-in electric pump products need to buy another foot pump or another purchase of electric inflator pump.
Folded clothes will have a fold trace, inflatable bed is the same, there will be a fold trace, when you pump, fold trace will slowly disappear, when the fold trace completely disappeared, said the bed has been full of air, this process is generally 1 to 2 minutes. Inflatable bed will not play explosion, because full, inflatable bed inside the air pressure than pump is also large, gas can not play in, so will not hit the bed explosion. Theoretically, the fuller you hit the gas, the greater the impact on your life. I suggest you: lie down and feel comfortable. On the other hand, if you feel more comfortable playing, you play more.
