I’ve spent time comparing the ASANEST Dual Sided Baby Breathable Crib Mattress and the ATTABABY Breathable Crib Mattress to figure out which one is actually worth your money. Both are standard 52-inch crib mattresses with machine-washable covers, but they take very different approaches to firmness and comfort.
If you’re a new parent trying to choose between a dual-sided mattress that grows with your child and a super breathable, firm single-layer option, this one’s for you. I’ll break down the real differences so you can pick the right one for your baby’s room.

Individual Product Breakdown
I tested both the ASANEST and ATTABABY crib mattresses by looking at their firmness, breathability, safety certifications, and how easy they are to clean. Here’s what I found after digging into the specs.
ASANEST Dual Sided Baby Breathable Crib Mattress
Dual-Sided | 5-inch thick | 9.5 lbs | Medium Firm | 2 Layers

- GROWS WITH YOUR CHILD FROM BIRTH TO TODDLER – Simply flip the mattress to...
- PREMIUM SUPPORT FOR HEALTHY DEVELOPMENT – Built with a high-density foam core...
The ASANEST is my top pick because it’s actually two mattresses in one. The firm infant side is perfect for newborns 0–12 months, and flipping it gives you a softer toddler side for ages 1–3. I love that the 5-inch thickness provides substantial cushioning without being too soft, and the gel-infused memory foam layer really helps wick heat away. The only downside I see is that it has a medium firm feel rather than an extra-firm core, which some parents might prefer for the infant stage.
✅ Pros
- Dual-sided design grows with your child from birth to toddler
- Gel-infused memory foam top layer helps keep baby cool
- OEKO-TEX Standard 100 and GREENGUARD Gold certified cover
- Machine washable zippered cover makes cleanup easy
❌ Cons
- Medium firm feel may not be as firm as some parents want for infants
- Only 37 customer reviews at launch, so long-term durability is unproven

- BREATHABLE CRIB MATTRESS SURFACE – COOLER, SAFER SLEEP Our breathable crib...

The ATTABABY is a solid choice if you want a no-nonsense, firm crib mattress that’s been tested hard. It’s Baby Safety Alliance verified and CertiPUR-US certified, which gave me confidence right away. With a 4.5-star average from 131 reviews, it’s way more proven than the ASANEST. I do wish it had a dual-sided option, though — at 4.5 inches thick with only one firmness level, you won’t be able to flip it to a softer side as your baby gets older.
✅ Pros
- Firm support is ideal for infant spinal development and safer sleep
- Breathable cover promotes airflow to reduce overheating
- Waterproof machine washable cover protects against leaks and spills
- Backed by a 7-year limited manufacturer’s warranty
Which One Should You Buy?
I know picking between these two can feel overwhelming, but the right choice really comes down to whether you want a mattress that adapts as your baby grows or one that stays super firm from day one. Here’s who each mattress is actually for.
ASANEST Dual Sided Baby Breathable Crib Mattress is right for you if…
- You want a mattress that grows with your child — flip it from the firm infant side (0–12 months) to the softer toddler side (ages 1–3).
- Your baby tends to sleep hot and you need the gel-infused memory foam layer to help wick heat away all night.
- You prefer the extra 0.5 inches of thickness (5 inches total) for a plusher feel without sacrificing the firm infant support.
ATTABABY Breathable Crib Mattress is right for you if…
- You want a proven, firm mattress with 131 customer reviews and a 4.5-star average rating backing its quality.
- The breathable cover and waterproof protection are your top priorities for reducing overheating and handling leaks.
- You value a 7-year limited manufacturer’s warranty and Baby Safety Alliance verification for extra peace of mind.
❌ Who Should Skip All of These?
If you’re looking for an organic or natural latex crib mattress that’s fully biodegradable, neither of these foam options will satisfy you. You’d be better off checking out brands that specialize in organic cotton or natural rubber cores instead.
For most parents, I’d go with the ASANEST Dual Sided because the two-in-one design saves you from buying a second mattress later, and the gel-infused memory foam is a real bonus for hot sleepers. But if you just want a rock-solid, breathable, and well-reviewed firm mattress, the ATTABABY won’t let you down.
Frequently Asked Questions
Which mattress is firmer: the ASANEST or the ATTABABY?
The ATTABABY is firmer. It’s listed as a “Firm” mattress with a single-layer high-resilience foam core, which is exactly what pediatricians recommend for newborns. The ASANEST is described as “Medium Firm” because it has a gel-infused memory foam layer on top of high-density foam, so it has a bit more give. If you want the strictest firmness for an infant, go with the ATTABABY.
Is the ASANEST worth the extra money over the ATTABABY?
I think it depends on whether you want a mattress that adapts. The ASANEST gives you two firmness levels in one 5-inch mattress, so you won’t need to buy a toddler mattress later. The ATTABABY is a single firmness at 4.5 inches thick, which means you’ll get the same feel from birth through toddlerhood. For most parents, the dual-sided design of the ASANEST makes it the better long-term value.
Which mattress has better breathability for hot sleepers?
The ATTABABY has a specific breathable cover designed to promote airflow, and it’s OEKO-TEX Standard 100 certified. The ASANEST relies on its gel-infused memory foam layer to wick heat away from your baby’s body. I’d give a slight edge to the ATTABABY for breathability since the cover is explicitly designed for air circulation, but the ASANEST’s cooling foam is also effective.
Which mattress is easier to clean?
Both have machine-washable covers, so you can’t go wrong here. The ASANEST has a zippered knitted cover that removes in seconds and dries quickly. The ATTABABY has a waterproof cover that protects against leaks and spills. I’d say the ATTABABY’s waterproof layer gives it a slight advantage for parents dealing with frequent accidents, but both are very easy to maintain.
Which mattress has better safety certifications?
The ATTABABY is Baby Safety Alliance verified, CertiPUR-US certified, and OEKO-TEX Standard 100 approved. The ASANEST also has OEKO-TEX Standard 100 certification, plus GREENGUARD Gold certification and CertiPUR-US certification for the core. Both are fiberglass-free and free of chemical flame retardants. I’d call it a tie — both are thoroughly tested for safety.
Which mattress is heavier and more durable?
The ASANEST weighs 9.5 pounds, while the ATTABABY weighs 8.8 pounds. The ASANEST is also thicker at 5 inches compared to the ATTABABY’s 4.5 inches. The ASANEST’s dual-layer construction with high-density foam and gel-infused memory foam feels more substantial. I think the ASANEST will hold up better over time, especially if you flip it between the infant and toddler sides.
My Final Verdict
The ASANEST Dual Sided Baby Breathable Crib Mattress is my clear winner because you get two mattresses in one — a firm infant side for newborns and a softer toddler side for ages 1–3 — all in a 5-inch thick, gel-infused memory foam design that keeps babies cool. The ATTABABY is a great runner-up if you just want a no-fuss, extra-firm mattress with a proven 4.5-star rating from 131 reviews and a 7-year warranty.
If you’re still on the fence, ask yourself this: do you want to buy one mattress that adapts as your child grows, or are you happy with a single firmness level from birth through toddlerhood? That answer will tell you everything you need to know.
