I have available a Woods 36 x 72 (Twin Size) Woods air mattress for $25.00. This mattress has been FD tested 4 times since it was produced in May of 2006. It works very well and has been kept clean and protected. It uses 4 D cells to blow it up. They do a fine job and it stays inflated for a good night's sleep. The motor does both inflate and deflate. This makes packing up very easy as it removes completely any air in the bag. It does not have any non manufactured holes. I slept very well on it. It comes with it's own storage bag. I will even throw in a mosquito net. If you pay the full price, I will add the 4 D cells I have to power it. They work very well. I have attached a photo of it inflated and in it's bag.
