Last homebirth we used the large fishy pool. Personally, it wasn't deep enough for my preference. It didn't cover my belly and when i leaned on the sides, my whole back was exposed..and I really wanted warm water on my back.
This time we got the large Birth Pool in a Box and it goes about 3 inches deeper than the large fishy. Plus it has handles and a seat that either you or your partner can sit on to support you, and it has the inflatable bottom just like the fishy pool. I LOVED it when I blew it up on a test run. It was super fast to blow up too cause it had larger holes for the electic pump, where as with the fishy it was the small holes that used the small attachment and it took about twice as long to inflate.
I'm not really too concerned about the uncomfortable level for the mw. I mean, yeah, I love my mw and all...but I'm looking for my own comfort here and if she REALLY needs to get at me, she will.

I'm kinda hoping this will be a pretty hands off birth though.
