I fancy giving one of these a go. However the cheapest I can find in the UK is £175 for a 5 week hire 
www.samanthajayne.co.uk/birthing-stool--backrest-5-week-hire-39-p.asp
for what is essentially a bit of plastic with a hole cut in it.
Also unsure if it will fit in the back of the car to take to the hospital.
Am wondering whether a nice long sit on the toilet would be a practical cut-price alternative 
What do you reckon? has anyone else had a go with a birthing stool? Are they worth it?
