Transform your child s room with a charming house-shaped bed that is both sturdy and safe. The house bed features a reliable structure that is made of solid wood. Safety features include 15.5"" high guardrails and a lockable door, providing a secure space for imaginative dreams. Inspired by Montessori teachings, this wooden house bed encourages independence and confidence in children. Besides, the low height reduces the risk of injury from falls. Additionally, the versatile design allows the bed to transition effortlessly from a warm harbor for sleep to an exciting indoor playground by removing your own mattress. A 4""-5"" thick mattress would be perfect.
