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.

Product Information
Grevia is designed as a 5-in-1 convertible crib that grows with your child:
Crib: newborn to around 3 years, up to 50 lbs
Toddler bed: about 15 months to 5 years, up to 50 lbs
Daybed / Sofa: about 3 to 5 years, up to 50 lbs
Full-size bed: 3 years and up, up to 50 lbs
Toddler rail, daybed/sofa parts, and full-size bed conversion kits are sold separately.
Yes. Grevia is GREENGUARD Gold Certified, meaning it has been tested for low chemical emissions. This helps support a cleaner indoor environment, especially in enclosed spaces like nurseries and apartments.
Grevia is tested to meet applicable ASTM and CPSC requirements for cribs in the U.S. It also features 2.09" / 5.3 cm slat spacing and a stable, full-size crib structure designed for everyday nursery use.
No. Grevia is not JPMA certified. Its current safety and material highlights are GREENGUARD Gold Certified, ASTM tested, CPSC compliant, and FSC® MIX Certified Wood.
Use the highest mattress position for newborns. Lower the mattress as soon as your baby can sit, reach, or pull up, usually around 5–6 months. Grevia has three mattress support positions: 20.47", 24.02", and 27.56".
Most parents transition between 18–36 months, or earlier if their child starts trying to climb out. Grevia’s toddler bed mode is intended for children at least 15 months old and up to 50 lbs. Toddler rail is sold separately.
For crib, toddler bed, daybed, and sofa modes, use a standard U.S. crib mattress. Recommended size: 52" × 27.6". The mattress should be at least 27 1/4" × 51 5/8" and 4–6" thick.
For full-size bed mode, use a full-size mattress: 74.8" × 54.33".
No. The mattress is not included. Choose a standard crib mattress that fits the size requirements above.
Crib mode does not require extra conversion parts. Toddler rail, daybed/sofa parts, full-size bed conversion kits, and the full-size metal bed frame are sold separately.
For full-size bed mode, use the compatible full-size conversion parts and a full-size metal bed frame. Follow the instructions for your chosen foundation or frame to ensure proper support.
Grevia has a solid wood frame made with responsibly sourced New Zealand pinewood and durable components. It is designed for daily use through crib and toddler stages, with a maximum weight capacity of 50 lbs.
Yes. Grevia’s footprint is 54.1" × 29.7", giving baby a full-size crib space while still fitting most nurseries, apartment bedrooms, and shared rooms.
Assembly usually takes about 30–45 minutes for two adults. Hardware and clear instructions are included, and no special tools are needed.
No. Grevia does not have wheels. This is intentional, so the crib stays stable in the nursery. If you need to move it, we recommend having two adults lift it or disassemble it as needed.
Grevia is finished with a low-VOC, lead-free, and phthalate-free coating. If your baby is teething, check the rails regularly and contact Harppa support if you notice any damage, chips, or loose parts.
For safe sleep, keep the crib clear of pillows, blankets, bumpers, stuffed toys, and other soft items. Use a firm, properly fitted mattress with a tight-fitting sheet.
Wipe the crib with a soft damp cloth and mild soap when needed. Do not use abrasive cleaners. Dry the surface after cleaning to help maintain the finish.
Grevia’s net weight is 47 lbs. Boxed size is 55.91" × 31.69" × 4.92".
Grevia includes a 24-month warranty. If anything feels off, contact Harppa support with your order number and product details.
