Query: Not just one but TWO were bad!

When I first set up this bed, I absolutely loved it. Within 3 weeks a huge lump started to form right in the middle of it. Amazon was good enough to ship me a replacement at no cost. Within a month after I got the new one...the exact same thing happened. Plus it kept loosing air, and I found tiny little holes all over it. I ended up using the entire patch kit it came with. Thats when I threw it in the garbage.I can understand defects...but I it shouldn't have happened twice in a row. I do not recommend this bed to anyone.
