Inspired by the steady and resilient gray seal, the Grevia 5-in-1 Convertible Crib is built to grow with your child, providing support and comfort at every stage. Just like the gray seal stays close to its pup, the Grevia Crib will be by your side, transitioning from a crib to a toddler bed, daybed, and finally, a full-size bed.
【5-in-1 Convertible Design】The Grevia Crib transforms to suit your child’s needs—from a crib for newborns to a toddler bed, daybed, sofa and full-size bed. This crib adapts to your child, saving you from buying multiple pieces of furniture over the years. (Conversion kits and guardrails sold separately.)
【3 Adjustable Mattress Heights】The Grevia Crib offers 3 mattress heights, measured from the Top of Rail to Mattress Depth, allowing you to easily adjust the mattress as your baby grows:
- Newborn: 20.47" (ideal for when your baby is learning to roll over, keeping the mattress closer to the top of the rail)
- Can Sit: 24.02" (perfect for when your baby starts sitting up, the mattress is lowered to a safer position)
-
Can Stand: 27.56" (great for toddlers who are standing, providing more space for your growing child)
【Certified Safety】Meets ASTM International and CPSC safety standards, ensuring that this crib is built to last through your child’s most active years.
【Maximum Weight Capacity】 Supports up to 50 lbs (22.6 kg), ensuring that your child can safely use it through the toddler and daybed stages, with a lasting conversion into a full-size bed.
【Classic & Timeless Design】Featuring clean lines and elegant simplicity, the Grevia Crib complements both modern and traditional nursery styles, making it a versatile choice for any home.
【Easy Assembly】This crib comes with clear instructions and all the necessary parts for easy setup. It’s designed to be simple to assemble, so you can spend more time with your baby and less time worrying about assembly.
【Convenient Assembly & Size】With overall dimensions of 54.09" L x 29.72" W x 35.83" H, the Grevia Crib fits well in most nursery spaces, offering ample room for your child to sleep and grow.
