This ergonomic cot is designed to reduce the stress placed on carers by increasing the base height and making access to the child easier. This cot has a higher mattress level and a front drop side that allows for easy access. Made from New Zealand pine sourced from sustainable forests. The smaller size is a good option for baby rooms. This ergonomic cot measures 67cm wide x 107cm deep x 126cm high. The base height excluding mattress from floor to base with wheels is 56cm high, and measures 49cm without castors. Drop side height from floor to top of the drop side when lowered with wheels is 85cm high. This ergonomic cot is designed for use with a mattress measuring 100cm wide x 60cm deep x 10cm high. It is not suitable for use with any other mattress except the Babyhood Mini Ergo Mattress. This cot is tested to the AS/NZS 2172:2003 Australian Standard for Domestic use Cot. Please note: It is important to raise the drop side on these cots evenly. Raising the drop side unevenly can cause the drop side to catch and it may get stuck, stopping it from locking into place. Babyhood suggests to avoid this is to push the locking button in as the side is lifted, this will allow the rail to lift all the way and then release the buttons allowing the drop side to lock. They also recommend that the drop sides are lubricated to ensure a smoother movement. Siqura surface sanitiser can be used to disinfect this item. This furniture is for indoor use only and assembly is required. Do not drag or pull this furniture piece. If the unit has castors only move when the castors are unlocked.
