If you are shopping for a crib that will serve your family for years, an adjustable mattress height is one of the most useful features to look for. A higher mattress position makes it easier to lift a newborn in and out, while a lower position keeps an older, more mobile baby from reaching the rails. Many of the cribs on the market offer this feature, but the details vary in ways that matter, from the number of height positions to how well the crib converts into a toddler bed later on. This guide compares five popular options so you can find the one that fits your nursery, your budget, and your long-term plans.

Our Picks: Best Crib With Adjustable Mattress Height reviews
DaVinci Charlie 4-in-1 Convertible Crib: A Long-Term Nursery Anchor
The DaVinci Charlie is a 4-in-1 convertible crib built to grow with your child. It starts as a standard crib and can later be converted into a toddler bed, a daybed, and a full-size bed. The listing notes that the conversion kits and bunkie board are sold separately, so you should budget for those extras if you plan to use the crib beyond the baby years. Its four adjustable mattress heights let you keep the mattress high during the early months, when reaching a newborn is a daily task, and lower it as your baby begins to sit and stand.
The design leans toward clean, modern lines in a white finish. The listing describes solid New Zealand pine construction and hidden hardware, so no screws or bolts are visible on the finished piece. This matters more than it might seem. Visible hardware can collect dust and can loosen over time, while a cleaner exterior is easier to wipe down. The crib is described as GREENGUARD Gold Certified, which means it has been tested for a broad range of chemical emissions, and the listing also says it is lead- and phthalate-safe.
In everyday use, owners tend to appreciate the smooth transition between height positions and the generous sense of solidity that solid wood brings. The main trade-off is that the full value of this crib depends on buying the extra pieces. If you only need a crib for the first two or three years, you may find the base price is not the whole story. Some parents also prefer a crib that does not require a separate conversion purchase to reach the toddler stage, so think about how many transitions you expect to make.
Compared with the other choices here, the Charlie stands out for its combination of four height positions, a broad conversion range, and a modern white look that suits many nurseries. It is a strong pick for families who want a crib that can serve as a long-term piece of furniture rather than a short-term purchase.
Pros:
- Four adjustable mattress positions to match your baby’s growth stages
- Converts to a toddler bed, daybed, and full-size bed for extended use
- Hidden hardware gives it a clean, polished appearance
- Solid New Zealand pine construction and GREENGUARD Gold Certified finish
Cons:
- Conversion kits and bunkie board are sold separately, which adds to the total cost
Verdict: The DaVinci Charlie is a strong choice for parents who want an adjustable crib that carries through to a full-size bed. If you plan to use the crib for many years and value a clean, modern look, it is worth the investment, provided you account for the conversion pieces.
Davinci Marley 3-in-1 Convertible Baby Crib: Warm Walnut Finish With Sustainable Credentials
The Davinci Marley is a 3-in-1 convertible crib in a walnut finish. It offers four adjustable mattress positions, so you can keep the mattress high for newborns and lower it as your baby becomes more active. The listing says it converts to a toddler bed and a daybed, with the toddler conversion kit sold separately. Notably, it does not list a full-size conversion, which makes it a slightly shorter-term option than the 4-in-1 models in this group.
The walnut color is warmer and more traditional than the white or light finishes found elsewhere in this lineup. The listing highlights solid New Zealand pinewood and engineered wood that is TSCA compliant, along with wood sourced from forests certified by the Forest Stewardship Council (FSC). For buyers who care about where their furniture materials come from, these details carry real weight. The finish is described as a non-toxic, multi-step painting process, and the crib is listed as lead- and phthalate-safe and as meeting ASTM International and U.S. CPSC safety standards.
Practically, the Marley suits a nursery where the furniture is meant to feel cohesive. The listing points to matching dressers, which makes it easy to build a coordinated room. One detail to plan for is that the crib is a standard regular size, and the manufacturer recommends its own non-toxic, GREENGUARD Gold mattresses for the best fit. Choosing a mattress that matches the crib’s dimensions is essential for safe sleep, so do not skip this step.
Compared with the Charlie, the Marley gives up the full-size conversion in exchange for a warmer aesthetic and a stronger sustainability story. It makes the most sense for families who prioritize natural wood tones and FSC-certified sourcing and who do not need a crib that turns into a full bed.
Pros:
- Four adjustable mattress positions for changing needs
- Walnut finish offers a warm, traditional look
- FSC-certified wood and GREENGUARD Gold Certification support a healthier nursery
- Designed to coordinate with matching dressers
Cons:
- Converts only to a toddler bed and daybed, with no full-size option, and the toddler kit is sold separately
Verdict: The Davinci Marley is a dependable, eco-conscious choice for parents who want a warm wood finish and adjustable height. Choose it if you value sustainability and a cohesive nursery look, and plan to purchase a mattress sized for the crib.
Graco Paris 4-in-1 Convertible Crib: Classic Style With Strong Safety Credentials
The Graco Paris is a 4-in-1 convertible crib with a classic, traditional design in a soft blush finish. It converts from a baby crib to a toddler bed, a daybed, and a full bed with headboard and footboard, though the crib-to-bed conversion kit is sold separately. The listing covers conversion well, but it does not specify the number of mattress height positions. That is an important gap for this article’s focus, so confirm the height adjustment details with the seller or product documentation before you buy if adjustable height is a must-have for you.
The build is described as pine and wood composites, which offers solid everyday strength. The Paris carries a GREENGUARD Gold Certified designation and is listed as Baby Safety Alliance verified, with independent testing at an accredited lab and annual re-testing to recent standards. Those third-party validations add credibility, especially for parents who want more than a manufacturer’s own claims. The listing also specifies crib dimensions of roughly 54.33 inches wide, 29.45 inches deep, and 43.07 inches high, which helps when you measure your space.
Assembly is described as taking about 30 minutes, with two adults recommended. That is a reasonable timeline, and the recommendation for a second pair of hands is worth taking seriously, since aligning long crib panels alone can be frustrating. The product is backed by a one-year limited warranty through Storkcraft, the licensed manufacturer.
Against the DaVinci models, the Paris is the most traditional in style and the most explicit about third-party safety verification. Its main question mark is the adjustable height detail. If you can confirm four positions, it becomes a very competitive option. If not, the lack of documented height adjustment may rule it out for families who want to lift the mattress for newborn care.
Pros:
- Classic design that suits a wide range of nursery styles
- Converts to a toddler bed, daybed, and full bed
- GREENGUARD Gold Certified and Baby Safety Alliance verified
- Listed assembly time is manageable, and the one-year warranty adds reassurance
Cons:
- The listing does not specify mattress height positions, so adjustable height should be confirmed before purchase
Verdict: The Graco Paris is an excellent pick for parents who prioritize classic style and independent safety verification. Before buying, confirm the mattress height details, since that feature is central to many families’ decisions.
DaVinci Kalani 4-in-1 Convertible Crib: Chestnut Warmth for Growing Families
The DaVinci Kalani is a 4-in-1 convertible crib in a rich chestnut finish. Like the Charlie, it offers four adjustable mattress positions, which allow you to keep the mattress high during the newborn stage and lower it as your baby grows. It converts to a toddler bed, a daybed, and a full-size bed, with the toddler and full-size conversion kits sold separately. Its conversion range makes it a strong long-term option for families who want the furniture to last well beyond the nursery years.
The listing describes 100% solid New Zealand pine and a non-toxic, multi-step painting process, with the crib listed as lead- and phthalate-safe. It is also described as GREENGUARD Gold Certified, with testing for more than 10,000 chemical emissions and VOCs. The chestnut color has more depth than the lighter finishes here, which can make a nursery feel warmer and more grounded. It pairs naturally with wood-toned dressers, and the listing suggests the matching Kalani dressers for a coordinated room.
There is one important practical note: the listing currently shows this crib as unavailable. That makes it harder to recommend as an immediate purchase, but it may still be worth watching if you prefer this specific finish. If it is not available when you shop, the DaVinci Charlie offers a very similar feature set in a white finish.
Compared with the Marley, the Kalani offers the broader full-size conversion path, while the Marley has a similar warm tone but a narrower conversion range. Compared with the Paris, it provides documented height adjustment, though it has less of the third-party verification language that the Paris highlights.
Pros:
- Four adjustable mattress positions for changing needs
- Converts to a toddler bed, daybed, and full-size bed
- Solid New Zealand pine with a warm chestnut finish
- GREENGUARD Gold Certified with a non-toxic painting process
Cons:
- The listing shows it as unavailable, and the conversion kits are sold separately
Verdict: The DaVinci Kalani is a well-rounded convertible crib with strong long-term value and a warm finish. If it is in stock when you shop and you like chestnut tones, it is a dependable choice. If not, the Charlie is a close alternative.
Albert Baby Astin 3-in-1 Convertible Crib: Budget-Friendly Guardrail Bundle
The Albert Baby Astin is a 3-in-1 convertible crib in a natural wood finish. It includes a toddler guardrail, which is a useful detail because the guardrail is often sold separately from other cribs. The listing says the crib transitions to a toddler bed with that guardrail and later to a daybed. It features a four-position adjustable mattress, so you can raise the mattress for newborns and lower it as your baby begins to roll, sit, or stand.
The Astin is built from solid New Zealand pine and features a sleek frame with a smooth finish. The listing mentions hidden screws and rounded edges, which contribute to a clean look and reduce the chance of snags. It is described as meeting ASTM and CPSC safety standards and as non-toxic and lead-free. The natural finish is lighter and more casual than the walnut or chestnut options, and it suits nurseries that lean toward Scandinavian or minimalist decor.
The Astin’s main appeal is value. Including the guardrail upfront means one less purchase to plan for in the toddler years. The listing also notes a one-year warranty and emphasizes straightforward assembly and a sturdy build. Keep in mind that the crib’s conversion path is shorter than the DaVinci models, since it does not list a full-size bed option. Like the other standard cribs here, you should buy a mattress that matches the crib’s dimensions and follow the manufacturer’s guidance on mattress fit for safe sleep.
Among the five, the Astin is the most budget-conscious option with full height adjustment. It may not offer the same depth of conversion or the same third-party certification language as the Graco, but it covers the essentials well for parents who want a practical, no-frills crib.
Pros:
- Includes the toddler guardrail, saving a separate purchase
- Four adjustable mattress positions for a practical range of heights
- Solid New Zealand pine with hidden screws and rounded edges
- Natural finish suits a light, modern nursery and comes with a one-year warranty
Cons:
- Shorter conversion path with no listed full-size bed option
Verdict: The Albert Baby Astin is a practical, value-focused crib that delivers adjustable height and a toddler guardrail in one package. It is a smart choice for families who want the essentials without paying for extra conversion pieces they may never need.
How to Choose a Crib With Adjustable Mattress Height
Understanding Mattress Height Positions
The most useful feature of an adjustable crib is the ability to change how high the mattress sits. Newborns are much easier to lift when the mattress is near the top of the frame, so you do not have to bend deeply into the crib every time you feed or comfort your baby. As your child grows and begins to move, the mattress should be lowered so that the rails are well above their reach. Several of the cribs in this guide offer four positions, which gives you a useful range of adjustment. When comparing models, look for the number of positions and confirm that the listing actually describes them. As the Graco Paris shows, not every listing spells out this detail, so it is worth checking before you commit.
Conversion Options and Long-Term Use
Convertible cribs are designed to adapt as your child grows, but the conversion paths differ. Some convert to a toddler bed and a daybed, while others add a full-size bed option with a headboard and footboard. Pay attention to whether conversion kits are included or sold separately. A crib that looks like a bargain can become more expensive once you add the pieces needed to reach the later stages. Think about how long you want the crib to serve your family, and make sure the conversion options match those plans. If you want a crib that can eventually become a full bed, a 4-in-1 model will usually offer more long-term flexibility.
Safety Certifications and Materials
Because a crib is where your baby will spend many hours each day, the materials and safety testing matter. Look for clear language about compliance with recognized safety standards, such as those from ASTM International and the U.S. Consumer Product Safety Commission. Certifications related to indoor air quality, such as GREENGUARD Gold, indicate that a product has been tested for a broad range of chemical emissions. Materials matter too. Solid pine is a common and durable choice, while FSC certification indicates that the wood comes from responsibly managed forests. Finishes should be described as non-toxic and lead- and phthalate-safe. Read these claims carefully, and compare how each manufacturer supports them with details rather than general promises.
Crib Dimensions and Mattress Fit
A crib is only as safe as the mattress that goes inside it. Many of the cribs here are standard-size, but the listings make clear that the right mattress matters. Measure your nursery space before you buy, and note the crib’s exterior dimensions, especially if the room is tight or the crib must fit between a wall and a window. Once you have the crib, buy a firm, properly sized mattress that fits snugly with no more than a small gap around the edges. Some manufacturers recommend their own mattresses for the best fit, which is a sensible guideline to follow. Avoid adding soft bedding, pillows, or bumpers, and follow the manufacturer’s instructions for setup.
Assembly, Hardware, and Build Quality
Assembly is an area where expectations often differ from reality. Some cribs can be assembled by one person in under an hour, while others are better tackled with a partner. The Graco Paris, for example, lists about 30 minutes of assembly with two adults recommended. Hidden hardware, like the kind described on several DaVinci and Albert Baby models, gives a cleaner look and reduces exposed screws that could loosen over time. Whatever crib you choose, tighten all hardware after assembly and check it periodically. Sturdy construction and secure joints matter more than any single feature, and they make the difference between a crib that feels solid for years and one that wobbles.
Style, Finish, and Nursery Fit
The finish you choose will shape the feel of the room. White and light natural finishes tend to feel bright and airy, which suits modern or Scandinavian nurseries. Walnut and chestnut tones create a warmer, more traditional look. Consider the other furniture you plan to buy, such as a dresser or changing table, and choose a finish that complements it. Many manufacturers offer matching pieces, which can simplify decisions, but mixing finishes can also work well if you choose a consistent undertone. Since the crib will be part of the room for years, pick a color you will still like once the nursery has grown into a child’s bedroom.
Warranty, Support, and Availability
Warranty coverage and customer support are easy to overlook, but they provide peace of mind when you are assembling a large piece of furniture. Several of the cribs in this guide list a one-year limited warranty, and the Graco Paris is backed by a support team through its licensed manufacturer. Also check whether the model you want is in stock. Availability can change, and a crib that is unavailable when you are ready to buy will delay your plans. If you find a model you like but it is not currently available, consider a close alternative with similar features rather than waiting indefinitely.
Frequently Asked Questions
What does an adjustable mattress height do for my baby?
An adjustable mattress height lets you set the mattress high when your baby is small, which makes it easier to lift them in and out without strain. As your baby begins to sit up, pull up, or stand, you can lower the mattress so the rails stay well out of reach. This flexibility supports your daily routine and helps you keep the crib safe as your child becomes more mobile.
How many height positions should I look for?
Four positions is a common and useful range, and several of the cribs in this guide offer it. Having four options gives you a gradual path from the newborn stage to the mobile stage. Fewer positions can still work, but more choices generally make it easier to match the crib to your baby’s development.
Do I need to buy conversion kits right away?
You do not need them for the crib stage, but you will need them if you plan to convert the crib into a toddler bed or a full-size bed later. Many convertible cribs sell these kits separately, so check the listing and factor them into your total budget. Buying them when you need them can help spread out the cost.
Which mattress should I use with these cribs?
Choose a firm mattress made for the crib’s size, and check the manufacturer’s recommendation for the best fit. A mattress that is too small leaves dangerous gaps along the edges. Avoid soft bedding, pillows, and bumpers, and follow all guidance in the crib’s instructions for safe sleep.
Is a GREENGUARD Gold certification important?
GREENGUARD Gold certification indicates that a product has been tested for a broad range of chemical emissions and is designed to contribute to cleaner indoor air. It is a helpful indicator for parents who want to limit exposure to chemicals in a baby’s sleep space. It is not the only factor to consider, but it is a meaningful signal when comparing products.
Can I use a crib with a toddler guardrail?
Some cribs, such as the Albert Baby Astin, include a toddler guardrail, which helps when your child transitions to a toddler bed. Others require you to buy the guardrail or conversion kit separately. Check what is included before you buy so you know what to expect when your child is ready for the next stage.
Which crib is best overall?
For most families who want a long-lasting, adjustable crib with a clear path to a full-size bed, the DaVinci Charlie is the strongest all-around choice. It offers four height positions, a broad conversion range, and a clean modern look. Families with a tighter budget may prefer the Albert Baby Astin, while parents who prioritize third-party safety verification and classic style should consider the Graco Paris after confirming its height details.
Final Recommendation
If you want the most complete package, the DaVinci Charlie is our top pick. Its four adjustable mattress positions, full-size conversion path, and hidden-hardware design make it a strong investment for a nursery you want to last. Budget-minded buyers will find good value in the Albert Baby Astin, which includes a toddler guardrail and offers full height adjustment. The DaVinci Marley and Kalani suit parents who want warm wood finishes and sustainability credentials, while the Graco Paris is a fine option for those who value classic style and independent safety verification, as long as the mattress height details meet your needs. Choose the crib that matches your room, your timeline, and your must-have features, and you will have a safe and practical space for your baby to sleep and grow.
