This castor set, in combination with the matching guardrail, transforms your babybay® in no time at all into a full-fledged bassinet. Thus your baby is also during the day always in your proximity. The parquet roles provided with a rubberized running surface preserve your floor and provide for an extra-quiet rolling, so that your baby can continue to sleep gently. Even on a normal carpeted floor the castors run safely and smoothly. The castors are made of abrasion-resistant plastic, two of the four castors are equipped with an easy-to-operate foot brake and can therefore be easily locked after moving. The set of castors can be easily mounted on your babybay® in combination with the sleeves which fit exactly into the provided drillings.
