hexagonal or oval birth pool? any thoughts? don't know which one to get

[Gemzooks]

I'm in Holland, company is called oerbron.nl

they have oval ones or hexagonal ones, is there any real difference?

any tips much appreciated!

thanks for response! No idea what position, last time was in hospital lying on left side wired up to a million things.. I think somehow the oval one might be more comfortable, have hip problems and can't go to the place to actually look at them..
