Outcome Measures
Primary Outcomes (1)
Instrumental vaginal births
Instrumental births include vacuum extraction and forceps delivery.
Recorded within 6 hours postpartum
Secondary Outcomes (4)
Administration of oxytocin for augmentation of labor
During labor and birth up to 36 hours postpartum
Postpartum blood loss
Up to 24 hours after birth
Perineal outcomes
Up to 36 hours after birth
Fetal outcomes
Up to 36 hours after birth
Study Arms (2)
Birth seat group
EXPERIMENTALRandomized to birth on a midwife designed birth seat
Non-birth seat group
NO INTERVENTIONRandomized to birth in any other position except on the midwife designed birth seat.
Interventions
Randomization takes place on admission to the labor ward when the participants are in active labor.Participants in this arm were to sit on the seat for 20 minute periods.After these 20 minutes, the participant should stand and mobilize during two to three contractions, before resuming the birth seat position. If progress of the descent of the fetal head was obvious the participant was not asked to mobilize.

- Body Mass Index less (BMI) than thirty
- gestational diabetes not requiring medical treatment
- women who were planning a vaginal birth after a caesarean section (VBAC)
