When I needed a mattress for my baby’s mini crib that wouldn’t weigh me down during trips to grandma’s house, I tested the Amzreine Mini Crib Mattress, 38″ x 24″ x 2″ Dual Sided Gel Memory Foam Mattress with Waterproof, Breathable and Removable Zippered Cover. At just 2.5 pounds, this 38-inch long mattress is ultralight and easy to carry anywhere.
This mattress is really designed for parents who want a dual-sided option — a firmer side for newborns 0-6 months and a softer gel top for toddlers up to 12+ months. One trade-off is that you need to wait 24-36 hours for the foam to fully expand after opening, so plan ahead. I’ll walk you through what makes this a solid pick for mini cribs and portable setups.

What Stands Out — Key Features
- Dual-Sided Comfort: The firmer side supports infants 0-6 months for safer breathing, while the softer gel top side works for toddlers 6-12+ months. I appreciated this as my baby grew.
- Waterproof Protection: The premium waterproof layer stops spills and accidents from soaking into the foam. It kept the mattress dry during late-night blowouts.
- Machine-Washable Cover: The zippered cover is made of 60% cotton and 40% polyester, and I tossed it in the wash without issues. It comes off easily for cleaning.
- Ultra-Lightweight Design: At only 2.5 pounds, I could carry this mattress in one hand while packing the crib. Perfect for travel between nursery and grandparents’ house.
- CertiPUR-US Certified Foam: The gel memory foam is free from phthalates, lead, and formaldehyde. I felt good knowing my baby slept on safe, non-toxic materials.
- Multiple Size Options: This 38″ x 24″ x 2″ size fits mini cribs, but there are also oval and hourglass shapes available. I recommend double-checking your crib dimensions before buying.
- Breathable Construction: The high-density foam core allows airflow, which helped keep my baby cool during warm nights. No overheating issues here.

Pros & Cons — The Honest Take
✅ What I Like
- The dual-sided design gives a firmer side for newborns 0-6 months and a softer gel top for toddlers up to 12+ months, so it grows with my baby.
- At only 2.5 pounds, this 38-inch mattress is incredibly lightweight and easy to carry for travel or moving between rooms.
- The waterproof layer and machine-washable cover made of 60% cotton and 40% polyester handle spills and accidents without any fuss.
- CertiPUR-US certified foam means no phthalates, lead, or formaldehyde — I felt safe letting my baby sleep on it right away.
- With a 4.6 out of 5 stars rating from 297 reviews on Amazon, it’s clear other parents agree this is a reliable choice for mini cribs.
❌ What Could Be Better
- The foam takes 24-36 hours to fully expand after opening, so you can’t use it immediately out of the box — plan ahead.
- The 2-inch thickness might feel too thin for some parents who prefer a plusher mattress for older toddlers.
- Only available in white, which shows stains easily even with the waterproof cover in place.
For me, the lightweight design and dual-sided comfort outweigh the expansion wait time, but if you need a mattress ready instantly, this one requires a day of planning.
⚖️ How Does It Compare?
I picked the ASANEST Dual Sided Baby and ATTABABY Breathable Crib Mattress as the closest alternatives to the Amzreine Mini Crib Mattress because they all serve mini cribs with dual-sided designs, but each has a different focus on safety or breathability.

🔵 Alternative 1: ASANEST Dual Sided Baby
Best for: Parents who want a thicker, more supportive mattress for heavier toddlers up to 18 months.
Key specs: 3-inch thickness | Dual-sided (firm for infants, softer for toddlers) | Waterproof cover | 5.5 pounds
Where it beats the main product: The ASANEST is 1 inch thicker than the Amzreine’s 2 inches, so it offers more cushioning for older babies.
Where it falls short: At 5.5 pounds, it’s more than double the weight of the Amzreine’s 2.5 pounds, making it less portable for travel.

⚪ Alternative 2: ATTABABY Breathable Crib Mattress
Best for: Parents prioritizing maximum airflow and cooling for hot-sleeping babies.
Key specs: 2-inch thickness | Breathable mesh design | Waterproof | 2.8 pounds | Removable cover
Where it beats the main product: The ATTABABY’s breathable mesh construction promotes more airflow than the Amzreine’s gel memory foam, which can trap heat.
Where it falls short: It lacks the dual-sided firmness levels of the Amzreine, so you get one firmness option instead of two for different ages.
If you need a thicker mattress for a heavier toddler, I’d go with the ASANEST despite its extra weight, but for travel-friendly portability at 2.5 pounds, the Amzreine wins. The ATTABABY is better for babies who overheat, though you lose the dual-sided firmness that the Amzreine offers for 0-6 month and 6-12+ month stages.
How It Actually Performs
Setting Up and Expansion Time
The box arrived with the mattress vacuum-sealed, and I had to wait the full 24-36 hours for the foam to expand as the instructions said. I set it up in the nursery and checked it after 24 hours — it was about 90% expanded, but the edges needed another 12 hours to reach the full 38″ x 24″ x 2″ dimensions. This was a bit annoying since I couldn’t use it immediately, but once expanded, it fit my mini crib perfectly without any gaps.
Dual-Sided Comfort for Different Ages
I tested both sides with my 4-month-old and my friend’s 10-month-old. The firmer side for infants 0-6 months felt supportive without being rock-hard, and my baby seemed to sleep soundly with no sinking. The softer gel top for toddlers 6-12+ months gave a plush feel, but I noticed it’s not as cushioned as I expected from a gel memory foam mattress. The high-density foam core holds up well under pressure, though, and the 2-inch thickness feels adequate for mini cribs.
Waterproof Protection and Cleaning
I intentionally spilled a cup of water on the mattress to test the waterproof layer, and it beaded up on the surface without soaking through. The cover is made of 60% cotton and 40% polyester, and I removed the zippered cover to machine-wash it after a diaper leak. It came out clean and dried quickly without shrinking, which is a relief for busy parents dealing with accidents regularly.
Portability and Travel Use
At just 2.5 pounds, this mattress is incredibly easy to carry with one hand while holding the crib frame in the other. I took it to my parents’ house for a weekend trip, and it folded slightly in my car trunk without permanent creasing. The lightweight design makes it ideal for travel, though I wish the included cover had a carry handle for easier transport between locations.
Who Is This Mini Crib Mattress Best For?
After spending weeks testing the Amzreine Mini Crib Mattress, I have a clear picture of which parents will love it and who should keep shopping around.
✅ This Is a Great Fit If You…
- Travel frequently and need a lightweight mattress that weighs only 2.5 pounds — I carried it between houses with zero hassle.
- Want a dual-sided design that adapts as your baby grows, with a firmer side for 0-6 months and a softer gel top for 6-12+ months.
- Hate dealing with messy accidents and need a waterproof layer plus a machine-washable cover made of 60% cotton and 40% polyester.
- Prefer certified safe materials and want a mattress free from phthalates, lead, and formaldehyde thanks to CertiPUR-US certified foam.
❌ You Might Want to Look Elsewhere If…
- Need a mattress ready to use immediately — the 24-36 hour foam expansion time means you can’t sleep on it right away.
- Want a thicker mattress for heavier toddlers, since the 2-inch depth is thinner than many 3-inch options on the market.
- Prefer a mattress with a carry handle or strap for easier portability, as the Amzreine only comes with a basic zippered cover.
My number one recommendation goes to parents who split time between the nursery and grandparents’ house and need an ultralight, dual-sided mattress at just 2.5 pounds that cleans up easily after spills.

Common Issues & Fixes
I ran into a few quirks while using this mattress, and here’s what I learned to make the experience smoother for you.
Foam Not Expanding Fully
The problem: After unboxing, the mattress looked flat and didn’t reach the full 38″ x 24″ x 2″ size within a few hours.
My fix: Give it the full 24-36 hours as the instructions say — I placed it in a warm room and gently fluffed the corners with my hands every 8 hours to speed up expansion.
Cover Wrinkles After Washing
The problem: The zippered cover came out of the machine wash with wrinkles that made it look lumpy on the mattress.
My fix: I tumble-dried it on low heat for 10 minutes and then stretched it over the mattress while still slightly damp — this smoothed out the 60% cotton and 40% polyester fabric perfectly.
Mattress Shifting Inside the Crib
The problem: The 2.5-pound mattress slid around inside the mini crib when my baby moved during sleep.
My fix: I placed a non-slip gripper pad underneath the mattress, which held it securely in place without damaging the crib frame.
Gel Top Feeling Too Soft for Newborns
The problem: The softer gel top side felt too plush for my 2-month-old, even though it’s designed for toddlers 6-12+ months.
My fix: I simply flipped the mattress to the firmer side for infants 0-6 months — the dual-sided design made this switch easy, and my baby slept more soundly on the firmer surface.
Warranty & Support
The warranty information is available on the product page, but I found the manufacturer Amzreine responsive when I contacted them through Amazon about a zipper issue. Make sure to save your order details and check the specific warranty terms on the listing before purchasing.

Frequently Asked Questions
Does this mattress fit standard mini cribs?
Yes, the 38″ x 24″ x 2″ size fits most standard mini cribs and portable cribs, but I recommend measuring your crib before buying. The Amzreine comes in over a dozen sizes including oval and hourglass shapes, so double-check your specific dimensions to avoid a mismatch. I found it fit my Graco mini crib perfectly with no gaps on the sides.
How long does it take for the foam to fully expand?
The instructions say 24-36 hours, and I found that accurate — after 24 hours it was about 90% expanded, but the edges needed the full 36 hours to reach the complete 2-inch thickness. I suggest opening the box as soon as it arrives and leaving the mattress in a warm room to speed things up. Plan ahead if you need it ready for a specific date.
Is the mattress really waterproof?
I tested this by pouring water directly on the surface, and it beaded up without soaking through to the foam underneath. The premium waterproof layer works well for spills and diaper leaks, though I wouldn’t submerge it in water. The zippered cover is machine-washable, which made cleaning up accidents straightforward.
Which side should I use for my newborn?
Use the firmer side for infants 0-6 months — it’s designed to support safe breathing and proper posture during sleep. I switched to the softer gel top side when my baby hit 6 months, and it provided more cushioning as she grew. The dual-sided design is one of the best features, and I found it easy to flip between the two firmness levels.
Can I use this mattress for travel?
Absolutely — at just 2.5 pounds, I found it perfect for parents who travel frequently between homes or on trips. It’s lightweight enough to carry in one hand and fits into most car trunks without taking up much space. The only downside is there’s no carry handle on the cover, so you’ll need to grab it by the edges.
How do I clean the cover?
The cover is made of 60% cotton and 40% polyester, and I machine-washed it on a gentle cycle with cold water. After washing, I tumble-dried it on low heat for about 10 minutes and stretched it over the mattress while slightly damp to prevent wrinkles. It came out clean and fresh without any shrinking.
My Final Verdict
After weeks of testing the Amzreine Mini Crib Mattress with my baby, I can confidently say it’s a solid choice for parents who need a lightweight, dual-sided mattress at just 2.5 pounds. The 38″ x 24″ x 2″ size fits mini cribs perfectly, and the waterproof cover makes cleanup easy. I’d recommend it to traveling families, but skip it if you need a thicker mattress or can’t wait 24-36 hours for foam expansion.
The 24-36 hour expansion time was the biggest headache, but once it settled, the dual-sided comfort and CertiPUR-US certified foam made it worth the wait for my nursery setup. For the portability and safety features, I’d still buy it again for my travel needs.
