We carry two sizes of balls. You want to pick a ball that will allow you to sit with your legs parallel to the floor and still be a bit soft. Most women will find a 65cm ball is great unless they have really long legs or are taller than 5’9″. Although if you like a softer ball, go with the larger one and underinflate it for more give. You should use your ball daily for optimal fetal positioning. The more familiar you are with the ball and being able to be comfortable on it, the more useful it will be for you to use in labor.
