The Astrid cot bed will grow with your little one. Suitable from birth until approx. 4 years old, the 3-position base height ensures there is a setting for each of your child’s milestones. When it is time to transition to a big bed the included dual ended safety rail will provide reassurance and familiarity during an often-daunting time. The Astrid cot bed requires an Obaby 140 x 70cm mattress, available separately.
