Brief Summary:
The purpose of this study is to determine whether birth on a birthing seat will effect numbers of instrumentally assisted vaginal births, vaginal traumas, blood loss,use of artificial oxytocin for labour augmentation and fetal outcomes.

Arm Intervention/treatment
Experimental: Birth seat group
Randomized to birth on a midwife designed birth seat
Device: BirthRite birthing seat
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.
Other Name: BirthRite® birthing seat

No Intervention: Non-birth seat group
Randomized to birth in any other position except on the midwife designed birth seat.

Primary Outcome Measures :
  1. Instrumental vaginal births [ Time Frame: Recorded within 6 hours postpartum ]
    Instrumental births include vacuum extraction and forceps delivery.

Secondary Outcome Measures :
  1. Administration of oxytocin for augmentation of labor [ Time Frame: During labor and birth up to 36 hours postpartum ]
  2. Postpartum blood loss [ Time Frame: Up to 24 hours after birth ]
    Blood loss postpartum is weighed and measured and maternal hemoglobin levels are registered.

  3. Perineal outcomes [ Time Frame: Up to 36 hours after birth ]
    Perineal outcomes include vaginal and perineal traumas, episiotomies and perineal edema.

  4. Fetal outcomes [ Time Frame: Up to 36 hours after birth ]
    Fetal outcomes include Apgar scores, cord blood pH levels and admissions to the NICU.
