Why We Tested the Babyletto Mercer Crib

One of my close friends was searching for a compact crib with storage for her small apartment. After weeks of research, she chose the Babyletto Mercer 3-in-1 convertible crib, and I had the chance to help her assemble and test it with her baby girl (8 months old at the time). What stood out to both of us was how this crib balances form and function. It’s stylish but practical, modern but surprisingly budget-friendly.

If you’re a parent who loves clean lines and values built-in storage, this review may help you decide whether the Mercer is the right nursery match for you.

What We Liked vs. Areas for Improvement

Here’s what stood out to us during testing—the good and the not-so-perfect.

Babyletto Mercer Crib Review: In-Depth Breakdown

1. Assembly and Setup

Assembly instructions were clear and well-organized. All parts were labeled, and nothing was missing. We spent most of the time attaching the drawer and making sure everything was tightened securely. Compared to some other cribs I have assembled, the Mercer was refreshingly easy to put together.

• Time to Assemble: ~1 hour
• Tools Required: Allen wrench (included)
• Ease of Setup: Straightforward

? Tip: Having a second person hold the panels steady makes setup much easier.

2. Safety and Stability

My friend’s daughter started using the Babyletto Mercer crib when she was around 8 months old, and she’s still sleeping in it now as a toddler. Over time, she went from sitting to pulling herself up and eventually jumping and bouncing against the sides, as toddlers love to do. Even with all that movement, the crib has stayed impressively stable. There’s been no wobbling, no squeaking, and no signs of looseness.

The babyletto Mercer 3-in-1 convertible crib meets all current U.S. crib safety standards and feels secure even with a toddler’s rougher movements.

When we first set it up, I also tested the crib for stability and safety, just like we do with every crib we review on our site. That includes pressing on different panels, checking joints, and scanning for any sharp edges or loose parts.

The Babyletto Mercer passed all our safety checks with flying colors, and real-life use only confirmed our impressions. It’s sturdy, well-balanced, and absolutely reliable from both a safety and durability standpoint.

• Safety Standards: Meets/exceeds ASTM and CPSC standards
• Safety Certification: GREENGUARD Gold Certified
• Stability: Very stable; passed pressure and shake tests

3. Durability and Build Quality

During setup and delivery, there were no chips or scuffs, which reflects the quality of the crib. After five months of use, the finish still looks beautiful. The surface has shown resistance to everyday wear, such as minor bumps and scrapes. The drawer continues to slide smoothly and feels just as sturdy as it did on the first day.

Update: My friend’s daughter has been using this crib for nearly three years. During that time, the crib has been converted twice—first from a crib to a toddler bed and now to a daybed. Despite these changes, the crib remains solid and stable. Her daughter did chew on the top rail while teething—something many toddlers do—but it only left a few faint tooth marks that don’t affect the crib’s structure or finish. Oh, and do not worry, the finish is safe for the child.

Overall, the Mercer has held up beautifully through the toddler years, and it still looks and functions great.

• Material: Solid New Zealand pine wood; MDF drawer
• Durability Rating: 9/10

4. Mattress Fit and Height Adjustability

The Babyletto Mercer crib features a sturdy metal spring mattress support that feels well-built and robust. You can adjust it to four different height levels, which gives you more than enough flexibility as your baby grows.

Since my friend’s daughter started using the crib at 8 months, we didn’t use the highest setting. Instead, she and her husband used two mattress heights—the second-lowest when their daughter was less mobile, and the lowest once she started pulling up.

She told me that adjusting the mattress support was pretty easy and didn’t give them any trouble. It only required moving a few screws and re-tightening them. The whole process took just a few minutes.

• Mattress Fit: Snug, secure fit with standard-size mattress
• Recommended Crib Mattress:
   • Brand’s Pick: Babyletto Pure Core Crib Mattress
   • Baby’s Little Place Pick: Newton Wovenaire Crib Mattress
• Adjustable Mattress Height: 4 levels

5. Under-Crib Storage Drawer

One of the most appreciated features of the Babyletto Mercer is its built-in drawer. It’s neatly tucked underneath the crib and divided into two sections—perfect for storing extra sheets, swaddles, or wipes. The drawer slides smoothly and feels just as sturdy today as it did when we first assembled it.

My friend especially liked how much this drawer helped keep the nursery organized. The compartments made it easy to separate everyday essentials from backup items.

The only downside here is that the under-crib drawer doesn’t have a lid or solid cover. When the mattress is set to a higher level, the drawer contents are a bit more visible. That said, we’ve noticed this with other convertible cribs that include drawers, like the Graco Remi and DaVinci Colby. It’s not a dealbreaker, just something to be aware of.

Still, if you’re tight on space or just love hidden storage, this feature alone sets the Mercer apart from many other cribs in the same price range.

• Design: Built-in, two-compartment storage
• Accessibility: Easy to reach from either side
• Visibility: Exposed at higher mattress settings
• Drawer Stability: Smooth glide, even after years of use

6. Convertibility and Versatility

The Babyletto Mercer is a 3-in-1 convertible crib, which means it grows with your child—from a standard crib to a toddler bed and eventually to a daybed.

Included Toddler Rail Saves Time and Money

One of the biggest advantages? The toddler bed comes with a safety rail. My friend really appreciated not having to shop around or worry whether a separate rail would fit properly.

“I’ve heard from other moms that finding a compatible toddler rail can be a nightmare,” she told me. “This saved us a lot of time and frustration.”

? Many cribs don’t include the rail, and by the time you need it, it might be sold out. Having it included with the crib is a big win.

Easy Transition to Daybed

Over nearly three years of use, my friend and her husband converted the crib twice—first to a toddler bed and more recently to a daybed.

“Switching it to the toddler bed was pretty easy,” she said. “My husband helped hold the rail in place while I screwed it in. But I did the daybed conversion by myself—it only took about 10 minutes.”

The conversion process is straightforward and doesn’t require any extra tools or parts.

Even after multiple conversions and years of daily use, the crib has remained stable and wobble-free. All joints are still secure, and the structure remains as solid as it was on day one.

• Conversion Modes: Crib → Toddler Bed (with guardrail) → Daybed
• Ease of Conversion: Simple, tool-free transitions after disassembly

? Wondering how to convert the Babyletto Mercer crib? The instructions are clear, and the parts are included in the box—you won’t need to search for add-ons later.

7. Design and Aesthetics

One of the first things I noticed while helping my friend assemble the crib was its low-profile frame, which is part of what makes this a great space-saving crib design.

Even though the crib sits lower to the ground, the distance between the top rail and mattress (especially at the lowest setting) still meets all safety standards. So no, your baby won’t climb out any sooner than they would in a taller crib.

This design also makes the crib much more accessible for shorter parents. My friend, who’s under 5’4”, mentioned how much easier it was to lay her daughter down without leaning awkwardly over the side.

Aesthetic Impact on the Nursery

The modern nursery aesthetic of the Mercer crib stands out thanks to its clean lines, open slats, and minimalist frame. These details also make the room feel more spacious and breathable, even in smaller nurseries.

“We live in a small apartment, and I love how open and uncluttered the room still feels with this crib in it,” my friend told me.

Thanks to its modern aesthetic and compact footprint, the Mercer is an ideal choice for parents seeking to create a clean, calm, and functional nursery.

However, the crib only comes in two color options—white and white with gray accents. That was perfect for my friend, who wanted an all-white nursery, but some parents might wish for a few bolder choices.

• Style: Minimalist, contemporary
• Color Options: White, Gray/White

? If you’re looking for something beyond neutral tones, this crib might feel limiting.

8. Price & Value for Money

You get convertibility, certified safety, and a built-in drawer without needing to buy extras like a toddler rail. For the features offered, it’s a great deal. You’ll be hard-pressed to find a crib in this price range that includes a toddler rail, under-crib storage, and Greenguard certification.

• Price: Mid-range ($300–$400)
• Value for Money: High

Why Mercer Wins:

While several cribs like the Kalani and Benton offer full-size bed conversions, only the Mercer includes both a toddler rail and a built-in drawer. The Mercer’s minimalist design and compact footprint are ideal for parents looking to save space and simplify transitions without buying extra conversion kits.

How Hadley Compares:

The Graco Hadley is the most similar to the Mercer in terms of functionality, as it includes an under-crib drawer and features a modern look. However, it lacks a toddler rail and may not feel quite as refined in terms of build quality. Still, for parents needing drawer storage and a lower price, the Hadley is a solid alternative.

Why You Might Choose Another:

If you’re focused on long-term use with full-size bed conversion or prefer more nursery color options, the Kalani or Emery might give you greater flexibility. Just remember, you’ll likely need to purchase additional accessories separately.

Bottom Line:

For parents seeking a sleek, toddler-ready crib with hidden storage and solid durability, the Babyletto Mercer remains one of the most practical and design-forward options on the market.
