[EX Q]: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
[EX A]: Negative

[EX Q]: Great Gift Great Value - I had to get one for myself. The glasses are over sized and the shaker stirs up a great batch of dry Martini's. I love the retro glass look and the shaker has a seal to prevent leaking while shaking your favorite drink.
[EX A]: Positive

[EX Q]: What the heck? This movie is rated R! The theatrical version was rated PG-13! Now I'm not allowed to get or see this movie, which was only mediocre to begin with. Great job!
