How We Compared These Full Size Cribs
Shopping for 5 best full size cribs for babies comes down to one question most guides dodge: which crib gives you the safest, longest-lasting sleep space for the money you actually spend? We built this comparison around full size cribs specifically, not convertible cribs in general, because roundups constantly muddle the two categories.
Every model below was scored on the same checklist, so you can compare them side by side.
- Safety verification: CPSC and ASTM compliance, plus GREENGUARD Gold or Baby Safety Alliance verification where the listing shows it
- Mattress fit: whether the crib takes a standard full-size crib mattress and how many adjustable mattress height positions it offers
- Conversion value: which conversion kits come in the box versus sold separately
The 5 picks below are all full size cribs that use a standard crib mattress, so mattress fit is consistent across the board. They differ in price, style, and how much conversion hardware comes included, a point that matters more than most parents expect.

1. Archer 4-in-1 Convertible Crib: Best Value Full Size Crib
The Archer is the crib we recommend first to parents who want a safe full size crib without paying for conversion stages they may never use. At $188.99, it is GREENGUARD Gold Certified.
It converts from crib to toddler bed, daybed, and full-size bed with headboard and footboard. Three adjustable mattress height positions let you lower the mattress as your baby learns to sit and stand.
Specs, Pros, and Cons
- Assembled dimensions: 55.75 in W x 30.50 in D x 43.75 in H
- Weight: 56.1 lbs
- Finish: Grey
Pros: Lowest price here with two separate safety certifications. The gently arched headboard and open slats read classic without looking dated, and the open sides give clear sightlines across the room.
Cons: Only one finish. The toddler guardrail and full-size bed rails are extra purchases, so budget for those if you plan to convert.
If the Archer fits your budget and your nursery palette, you can view the Archer crib's full specs and price before you commit.
2. Kendall 6-in-1 Convertible Crib: Best Heirloom Design
Crown and dentil molding set the Kendall apart from everything else in this roundup, the crib for parents who want furniture that looks inherited rather than bought.
The 6-in-1 design covers crib, toddler bed, daybed, sofa, and full-size bed with or without footboard. Daybed and sofa rails come in the box. The toddler guardrail and full-size bed rails are sold separately.
Specs, Pros, and Cons
- Assembled dimensions: 55 in W x 30 in D x 42.75 in H
- Weight: 54.67 lbs
- Finishes: Antique White, Teak Brown
Pros: The molding detail is genuinely distinctive at this price, and the textured finish hides everyday scuffs better than a flat painted surface.
Cons: No GREENGUARD Gold certification listed, and you pay a premium for the decorative detailing rather than extra conversion hardware.
Parents who want the heirloom look can shop the Kendall 6-in-1 crib to check finishes and availability.
3. Saint 4-in-1 Convertible Crib: Best Jenny Lind Style
Jenny Lind cribs have a devoted following, and the Saint delivers the turned-spindle look without the fragility of cheap imitations. It is crafted from sustainable New Zealand pine with a non-toxic, lead- and phthalate-safe finish, and it is GREENGUARD Gold certified.
At $498.00, the Saint converts to a toddler bed, daybed, and sofa, and the toddler guardrail is included, which is unusual at this price and saves you a separate purchase.
Specs, Pros, and Cons
- Dimensions: approximately 54.75 in W x 30.75 in D x 39 in H
- Weight: approximately 52 lbs
- Finishes: Bianca White, Grey, Black, Teak Brown
Pros: Four finish options, the guardrail included, and real wood spindles. The low profile makes it easier to reach a newborn without straining your back at 3 a.m.
Cons: No full-size bed conversion, so this crib tops out at the sofa stage. If you want a bed for a school-age child, look at the Kendall or Juliette instead.

4. Poppy 4-in-1 Convertible Crib: Best Modern Two-Tone Look
Two-tone finishes are everywhere in nursery design right now, and the Poppy executes the trend better than most. Contrasting round spindles sit against a natural wood base and feet for a warm, contemporary feel. At $298.00, it is mid-pack on price and GREENGUARD Gold certified.
Kendall 6 In 1 Convertible Baby Crib with Classic Molding and Adjustable →
It converts to a toddler bed, daybed, or sofa. The daybed and sofa rail is included; the toddler guardrail is sold separately.
Specs, Pros, and Cons
- Assembled dimensions: approximately 54.25 in W x 30.75 in D x 34 in H
- Weight: approximately 49 to 57 lbs depending on finish
- Finishes: Bianca White with Natural, Grey with Natural, Midnight Grey with Natural
Pros: The lowest assembled height in this group at 34 inches, which makes it a strong pick for a small nursery or a room with a sloped ceiling. Three two-tone colorways give you room to match existing decor.
Cons: No full-size bed conversion, and the toddler guardrail is a separate purchase.
If the two-tone look is what you are after, check the Poppy crib's colorways and pricing.
5. Juliette 6-in-1 Convertible Crib: Best for Full Bed Rails Included
Here is where the total cost of ownership math gets interesting. The Juliette costs $539.00, the most in this roundup, but ships with both the toddler guardrail and the full-size bed rails included, separate purchases on the Archer, Kendall, and Poppy.
The 6-in-1 design covers crib, toddler bed, daybed, sofa, and full-size bed. It is GREENGUARD Gold certified, meets or exceeds CPSC and ASTM standards, and uses a standard full-size crib mattress.
Specs, Pros, and Cons
- Finishes: White, Grey
- Construction: Solid wood and engineered wood, stationary sides
- Included: Toddler guardrail, full-size bed rails
Pros: Every rail included, so no surprise purchases later. Graceful curved frame that suits both classic and modern rooms.
Cons: Highest upfront price, and only two finish options. You are paying for the included hardware, not decorative detailing.
To confirm what ships in the box, review the Juliette 6-in-1 crib's included rails.
Best Convertible Cribs: Which Conversion Stages Actually Matter
Most parents overestimate how many conversion stages they will use, the single biggest money-waster in crib shopping. A 6-in-1 sounds like better value than a 4-in-1 until you realize the sofa stage rarely gets used and the full-size bed stage requires a separate mattress and bedding anyway.
The stages that matter are crib, toddler bed, and full-size bed. The daybed and sofa stages are nice for a reading nook, but they are not why you buy a crib.
The total cost of ownership math
Here is the part most roundups skip: the sticker price is not what you pay to use every stage. Add the conversion hardware not in the box plus a standard full-size crib mattress, and the ranking can flip.
- Archer 4-in-1 ($188.99): daybed rail included; toddler guardrail and full-size bed rails sold separately. Budget for both if you plan to convert.
- Kendall 6-in-1 ($448.00): daybed and sofa rails included; toddler guardrail and full-size bed rails sold separately.
- Saint 4-in-1 ($498.00): toddler guardrail included; no full-size bed conversion, so this crib tops out at the sofa stage.
Parents who intend to use the full-size bed stage often spend more on a lower-priced crib plus separate rails than they would have on the Juliette up front.
Mattress fit and the safety test that matters most
Every crib here takes a standard full-size crib mattress, so sheets and mattresses stay interchangeable. The safety test that matters most is a snug fit with no gap at the rails, a gap wider than about two fingers is a red flag. Confirm your mattress is labeled a standard full-size crib mattress and check the fit.
Verify current recalls and confirm the standards
Before buying any crib, new or used, check the CPSC crib recall database for the model number. Used cribs deserve extra scrutiny: missing hardware, drop sides, and modified slats are all disqualifying. Then confirm the safety standards: the CPSC crib safety standards set the federal requirements for slat spacing, hardware, and mattress support. A crib that meets or exceeds CPSC and ASTM standards, like every model here, clears that bar.
Will a full-size crib fit your nursery?
Measure your floor space against the assembled dimensions before ordering. The Archer (55.75 in W x 30.50 in D) and Kendall (55 in W x 30 in D) run about 55 inches wide, so plan clearance on both sides to reach the mattress and change sheets.
At Bungle Nursery Cribs, every order ships free with insured shipping, and our price match guarantee means you can buy with confidence. Our 24/7 expert customer support team can help you compare mattress fit and conversion options before you order.
Frequently Asked Questions
What is the most common full-size crib mattress size?
A standard full-size crib mattress measures about 28 inches wide by 52 inches long, and every crib in this guide fits that size. Buy the mattress separately, then check the gap: no more than two fingers should fit between the mattress edge and the crib rail on any side. A tight fit stops a baby from slipping into the gap, so measure before you assemble.
Is it safe to buy a used crib?
Sometimes, but only with verification. Used crib safety depends on three things: a manufacture date after 2011, no drop-side rails, and complete hardware with no missing or replaced screws. Check the CPSC recall list by model number, inspect every slat for cracks, and skip any crib that has been repainted or modified. If the seller cannot show a model number or manual, walk away.
How long can a child use a convertible crib?
Most children stay in the crib stage until about 35 inches tall or when they start climbing out, usually between 18 months and 3 years. After that, a 4-in-1 or 6-in-1 model converts to a toddler bed, then daybed or sofa, and some reach a full-size bed that lasts into the school years. The crib frame itself is built for years of daily use.
What should I look for when buying a full size crib?
Start with current CPSC and ASTM compliance, then confirm the crib fits a standard full-size crib mattress with a snug gap. Look for stationary sides, at least three adjustable mattress height positions, and a GREENGUARD Gold certification if indoor air quality matters to you. Finally, count the conversion rails included, since toddler guardrails and full-size bed rails are often sold separately.
Are all full-size crib mattresses the same size?
They are close but not identical. Standard crib mattresses are built to roughly 28 by 52 inches, but foam and innerspring models can vary by a fraction of an inch at the corners. That is why you fit the mattress to the crib rather than the other way around. Bring your crib's interior measurements when shopping, and test the gap after the mattress is in place.
