It's not metal sided, it only has metal poles holding up the sides, the rest is just liner. That's why it was so cheap.
But I guess if you were to hit a pole wrong in a catasphrophic event it could be bad too.
We're working on draining it into the bushes now, by this weekend we'll have it done right

You can get a pool, these are really inexpensive and you can get a smaller one that's cheaper.
This is actually big enough to do some fair amount of swimming. I had a great time in it today.

We thought it would be really funny/cool to get a small inflatable that we could take on road trips with us. Could you imagine a small 10'x24" at AR we could lounge in?
