I tried last night to sleep on the floor. Well trust me when I say the floor is HARD. I woke up several times with my back killing me. The last time I woke up I got on Wal-Mart.com and check out their prices for this Twin Air Mattress. I was surprised on how much it cost - $21.00. I thought I can afford that.
I took off to our local store. I was surprised again at how many people are out this time of the morning. I went to the bedding department first and found another Air mattress but the cheapest one there was $40.00. I went to the Sporting goods and there was the Coleman Air Mattress.
Keith has a Rainbow Vacuum that has a blowing valve and I blew up my mattress in less than a minute.
The valve on the mattress is the best that I have ever seen, it has two stoppers built in. One is on the inside of the mattress and the other is on the outside. All you do is pull out the port and blow up the mattress, when its full, just push it back in and the plug on the inside stops the air from coming out. Then put on the cap on the outside. That was it. It was super easy, even for me, that is still half asleep.
