[Q]: Needed place for kids to sleep while visiting grandma and now they argue over who gets to sleep on the air mattress. Both think it's more comfy than their bed at home.Would have given 5 stars, but the bag it comes with to put it in is worthless, no chance of ever getting it in there again.
[A]: Positive

[Q]: Comfortable right out of the box. Well made. Durable. Can't vouch for the waterproofing of them, as I have learned many moons ago.....no shoes are waterproof. I refuse to test them, once you do...they never seem to be the same.
[A]: Positive

[Q]: While visiting Quebec City, I heard her CD playing in a clothing store. I asked who the artist was, walked to the music store down the street and bought it. If you like Jewel, Tori Amos, Alanis Morisette, etc. you'll LOVE this. I'm now buying several more through amazon.com for my sister and a couple friends for X-mas because they heard my CD and LOVED it. Can't find it in any US stores...yet! It's mainly in French, but her voice and the music is so good, it doesn't matter.
[A]:
Positive
