CONVERSION OPTIONS

As your needs change - a child wants a new bed, or maybe a sibling arrives - the bed can keep up with the new needs.

Choose the bed you want to convert and see the conversion options in the bed converter.

We guarantee a five-year availability of the standard conversion kits for all convertible beds from the date of purchase.

SAFETY AND COMPLIANCE

Tested and approved according to safety standard EN 747-1:2012+A1:2015.

According to EN 747 loft beds and the upper bed of bunk beds are not suitable for children under 6 years due to the risk of injury from falls.

A smaller child can sleep in the lower bed of bunk beds, possibly with a bed guard for extra safety.
