As your child learns to sit and stand, the mattress base can be lowered. The three available base heights provide extra security and reassurance. Also by simply removing the fixed sides and splitting the end panels, the cot bed converts seamlessly from a cot into a cosy and stylish junior bed. Once the change is complete, the bed can be suitable for a child up to approximately 3 years, offering maximum durability and great value. Why Buy Me?
