Query: The 1st one leaked but the second one is great!

The first bed that I ordered leaked badly within the first 24 hours. I returned it and took a chance and ordered another from Amazon. It arrived just in the nick of time for my house guests. That was 3 weeks ago and since I was expecting another house guest soon, we decided to leave it inflated. It has inflated for three weeks now and I haven't had to add any more air! We have been lounging around on it and I'm happy to say that it is quite comfortable. I did notice that the "sure grip bottom" doesn't really grip on a hardwood floor. I put a very small "no-slip" rug pad under a portion of it and now it stays put.
