Etekcity Air Mattress Twin Size, 9"

I bought this in order to have a mattress while I was moving (after the packers took my mattress to my new house and until they delivered my stuff). I was initially confused with the inflation process, but it just required reading directions. Efficiency: The mattress inflated very quickly and without any problems. It sealed off perfectly and did not deflate. I slept on it for 2 weeks on one place, deflated, and then re-inflated for another 2 weeks at the next place. I never had to re-fill or augment: the air was tight. Practicality: I was able to unroll and inflate with no problem. Also, when I deflated this, I realized one could deflate with the inflater and this sucked the air out like one of those vacuum packers. It was great. Just know that it goes FAST, so if you're not paying attention, it will squish into a weird an annoying shape. Value for cost: Totally worth the price. I am actually planning to buy another one for guests. Durability: It had no problems with the move, inflating and deflating, movement, or use. Also, I have two small ~20 lb dogs who have enjoyed bouncing on it. No problem at all, although I was a bit worried when they first sprinted onto it. I wouldn't recommend a 100lb dog with claws who likes to dig, but this did not readily pop with the little ones. Overall: Buy. Worth it. Good. Sturdy. And practical.
