The Storkcraft Santorini Deluxe five-in-one convertible crib is made to grow with your little one. Build to adapt, it transforms from a crib to a toddler bed, daybed, or full-size bed as your child reaches new milestones. The adjustable mattress support base offers four height options to lower as your child grows. A toddler safety guardrail is added for extra peace of mind.
