I remember the struggle of finding a mini crib mattress that didn’t feel like a rock or a sponge. So I tested the Lisara Mini Crib Mattress, 38″ x 24″ x 3″ Dual Sided Gel Memory Foam Mattress with Waterproof, Removable and Breathable to see if it could actually deliver on both comfort and safety.
This mattress is really for parents who want a two-in-one solution as their baby grows from infant to toddler. The dual-sided design offers a softer gel memory foam side and a firmer high-density support foam side. The only catch is that the 3-inch thickness might not fit every bassinet, so you need to measure first.

What Stands Out — Key Features
- Dual-Sided Firmness: I love that this mattress has a softer gel memory foam side for comfort and a firmer high-density foam side for support as your baby grows. It’s like getting two mattresses in one.
- Waterproof TPU Cover: The premium TPU membrane on both sides really works. I spilled water on it and it beaded right up, so no worry about accidents soaking through.
- Breathable Ice Silk Cover: The cover is 35% ice silk and 65% polyester, which felt cool and smooth to the touch. My baby didn’t get sweaty during naps, which was a relief.
- Removable Zipper Cover: The zipper makes it easy to take the cover off for washing. I machine-washed it at 30 degrees Celsius with mild detergent, and it came out looking like new.
- Lightweight at 3 Pounds: Weighing only 3 pounds, this mattress is super easy to lift and move between rooms. I can swap it from the mini crib to the pack n play without any hassle.
- Multiple Size Options: It comes in over a dozen sizes, from oval 30″ x 18″ to rectangle 47″ x 23.6″. I tested the 38″ x 24″ mini crib size, which fits most standard bassinets.
- Medium Firmness: The mattress is rated as medium firm, which is the sweet spot for infant sleep safety. It’s supportive enough for newborns but still comfortable for toddlers.

Pros & Cons — The Honest Take
✅ What I Like
- The dual-sided design gives me a softer gel memory foam side for comfort and a firmer high-density foam side for support, all in one mattress.
- The waterproof TPU cover on both sides handled a spilled sippy cup without a drop soaking through to the foam.
- At only 3 pounds, I can easily lift this mattress in and out of the mini crib without straining my back.
- The ice silk cover (35% ice silk, 65% polyester) felt noticeably cool and smooth, which kept my baby from overheating during summer naps.
- The zippered cover comes off easily for machine washing at 30 degrees Celsius, and it held up perfectly after three washes.
❌ What Could Be Better
- At 3 inches thick, this mattress is thinner than some standard crib mattresses, so it might not work for deeper bassinets or pack n plays.
- The cover is waterproof but not completely stain-resistant — I noticed a faint mark after a diaper leak that required extra scrubbing.
- I wish the zipper was a bit more heavy-duty; it felt a little flimsy when I pulled it around the corners.
For me, the pros clearly outweigh the cons — the dual-sided firmness and waterproof cover are exactly what I needed for a growing baby. The thinness is the main trade-off, but it’s a fair one for a lightweight mini crib mattress.
⚖️ How Does It Compare?
I compared the Lisara Mini Crib Mattress against two popular alternatives to see how it stacks up for different needs. I picked the AOHWIDER 47×23.6 Bedside Crib for its larger size and the ASANEST Dual Sided Baby for another take on dual firmness.

🔵 Alternative 1: AOHWIDER 47×23.6 Bedside Crib
Best for: Parents with a larger bedside bassinet who need a 47-inch long mattress.
Key specs: 47″ x 23.6″ size | Dual-sided foam | Waterproof cover | Check listing for exact thickness
Where it beats the main product: It offers a much longer length at 47 inches compared to the Lisara’s 38 inches, making it a better fit for larger bedside sleepers.
Where it falls short: It doesn’t list an ice silk cover or the same breathability specs, and it may be heavier than the Lisara’s 3-pound design.

⚪ Alternative 2: ASANEST Dual Sided Baby
Best for: Parents wanting a dual-sided mattress with a slightly different foam composition for their mini crib.
Key specs: Dual-sided firmness | Waterproof cover | Removable cover | Check listing for exact dimensions and weight
Where it beats the main product: It offers a similar dual-sided concept, which gives another option if the Lisara’s specific gel memory foam feel isn’t what you’re after.
Where it falls short: It doesn’t have the same 4.5-star rating from 606 reviews that the Lisara has, and it may not include the ice silk cover for cooling.
If you need a longer mattress for a bedside bassinet, I’d go with the AOHWIDER at 47 inches. But for most parents with a standard 38″ x 24″ mini crib, the Lisara’s 3-pound weight and proven 4.5-star rating from over 600 buyers make it the safer bet. The ASANEST is a decent backup, but it doesn’t offer anything extra that the Lisara doesn’t already cover.
How It Actually Performs
Dual-Sided Firmness in Real Life
I tested both sides of this mattress over two weeks, and the difference is noticeable. The softer gel memory foam side feels plush but still supportive — my baby sank in just enough to be comfortable without any risk of sinking too deep. The firmer high-density foam side is noticeably sturdier, which I preferred for older infants who need more support. I appreciate having both options in one 3-inch thick mattress, though I wish the transition between sides was a bit more dramatic for growing babies.
Waterproof Protection Tested
I poured a full cup of water on the cover and watched it bead up and roll off instantly. The premium TPU membrane on both sides really works — not a single drop reached the foam underneath, even after letting it sit for 10 minutes. I also tested it with a warm bottle of milk, and it repelled that just as well. For parents dealing with diaper leaks or spit-up, this is a huge relief. The cover stayed dry on the surface, and I just wiped it clean with a cloth.
Breathability and Temperature Control
The ice silk cover (35% ice silk, 65% polyester) genuinely feels cool to the touch. I placed my hand on it after the mattress sat in a warm room, and it was noticeably cooler than standard polyester covers I’ve used. My baby didn’t wake up sweaty during afternoon naps, which was a problem with our old mattress. The breathability claim holds up — air seems to flow through the fabric well. That said, on very hot days, the 3-inch foam still retains some warmth, so it’s not a miracle cooler.
Ease of Cleaning and Care
I machine-washed the zippered cover at 30 degrees Celsius with mild detergent, and it came out looking brand new. The zipper held up fine through three washes, but I do pull it gently around the corners to avoid stressing the teeth. The cover dries quickly on a low tumble dry setting. One thing I noticed: the waterproof layer makes the cover slightly stiff after washing, but it softens up again after a day of use. At 3 pounds, the whole mattress is easy to carry to the laundry room.
Who Is This Mini Crib Mattress Best For?
After spending weeks with the Lisara Mini Crib Mattress, 38″ x 24″ x 3″ Dual Sided Gel Memory Foam Mattress with Waterproof, Removable and Breathable, I have a clear picture of who will love it and who might want to pass. Here’s where it shines and where it doesn’t.
✅ This Is a Great Fit If You…
- Have a standard 38″ x 24″ mini crib or bassinet and need a mattress that fits without any gaps.
- Want a dual-sided mattress that grows with your baby — the softer gel memory foam side for newborns and the firmer high-density foam side for toddlers.
- Deal with frequent diaper leaks or spit-up and need a truly waterproof cover that won’t let anything soak into the foam.
- Prefer a lightweight mattress at only 3 pounds that’s easy to lift out for cleaning or moving between rooms.
❌ You Might Want to Look Elsewhere If…
- Need a thicker mattress for a deeper crib or pack n play — the 3-inch height is slimmer than standard 4 or 5-inch options.
- Want a mattress that’s completely stain-resistant — the waterproof cover cleans well but can show faint marks after heavy leaks.
- Prefer a firmer zipper — the one on this cover works fine but feels a bit light-duty compared to some alternatives.
My top recommendation is for parents with a standard mini crib who want a practical, dual-sided mattress that handles messes well and won’t break the bank.

Common Issues & Fixes
I ran into a few quirks with the Lisara Mini Crib Mattress during my testing, and I figured out simple fixes for each. Here’s what to watch for and how to handle it.
The cover feels stiff after washing
The problem: After I machine-washed the cover at 30 degrees Celsius, the waterproof TPU layer made it feel a bit stiff and crinkly.
My fix: I let the cover air dry for a few hours, then tossed it back on the mattress. The warmth from the foam and normal use softened it up within a day, and it felt just as smooth as before.
The zipper gets stuck on corners
The problem: When I tried to zip the cover back on, the zipper occasionally snagged on the fabric around the rounded corners of the 38″ x 24″ mattress.
My fix: I pinch the fabric flat on both sides of the zipper track before pulling, which keeps the teeth aligned. Going slow around the curves also prevents any fabric from getting caught in the zipper.
The mattress shifts inside the cover
The problem: After a few nights of use, I noticed the foam core slid slightly inside the cover, leaving a small gap at one end.
My fix: I unzipped the cover, centered the foam, and re-zipped it while holding the cover taut. The snug fit of the 3-inch foam inside the cover keeps it in place once it’s properly aligned.
The waterproof layer makes a crinkling noise
The problem: When I first laid the mattress down, the TPU membrane made a faint crinkling sound every time I pressed on it.
My fix: I let the mattress sit for a day at room temperature, and the noise faded significantly as the foam and cover settled together. A quick stretch of the cover over the mattress also helped reduce any loose spots.
Warranty & Support
The Lisara comes with a product warranty that you can check on Amazon for full details. I didn’t need to contact support during my testing, but the brand has a standard return policy through Amazon, so you’re covered if anything goes wrong.

Frequently Asked Questions
Does this mattress fit a standard 38″ x 24″ mini crib?
Yes, it fits perfectly. I measured my mini crib before ordering, and the 38″ x 24″ size matched exactly with no gaps on the sides. Just make sure to measure your own crib first because Lisara offers over a dozen sizes, and this one is specifically for mini cribs. The 3-inch thickness also sits flush with most bassinet bottoms.
Is the cover really machine washable?
Absolutely. I washed it three times at 30 degrees Celsius with mild detergent, and it held up great. The zipper survived all the cycles without any issues, and the waterproof layer didn’t peel or crack. Just don’t use bleach or iron it — the instructions are clear about that. I let it air dry, and it was ready to use again in a few hours.
Which side should I use for my newborn?
I started my baby on the softer gel memory foam side for comfort during those early months. The dual-sided design means the softer side is best for infants who need a little more cushioning, while the firmer high-density foam side is better for older babies and toddlers who need more support. I switched my baby to the firmer side around 6 months old.
How heavy is this mattress?
It weighs only 3 pounds, which is surprisingly light for a foam mattress. I can easily lift it with one hand while holding my baby in the other arm. That makes it perfect for moving between rooms or taking on trips. The lightweight design also means it doesn’t put much pressure on the crib’s support slats.
Does it have any chemical smell out of the box?
I noticed a faint new-foam smell when I first unboxed it, but it faded completely after about 24 hours of airing out. I left it in the nursery with the window open for a day, and by the next morning, there was no odor at all. I found it perfect for a baby’s sensitive nose once that initial smell dissipated.
Can I use this mattress in a pack n play?
Lisara actually makes a specific Pack n Play Mattress size at 38″ x 26″, which is slightly wider than this 38″ x 24″ mini crib version. I tried the mini crib size in a standard pack n play, and there was about an inch of gap on each side. For safety, I’d recommend buying the dedicated pack n play size if that’s your setup.
My Final Verdict
After weeks of testing the Lisara Mini Crib Mattress, 38″ x 24″ x 3″ Dual Sided Gel Memory Foam Mattress with Waterproof, Removable and Breathable, I can confidently say it delivers on its promises. The dual-sided firmness, waterproof TPU cover on both sides, and lightweight 3-pound design make it a practical choice for most parents. I’d recommend it to anyone with a standard 38″ x 24″ mini crib who wants a versatile, easy-to-clean mattress. Skip it if you need a thicker 4 or 5-inch option for a deeper bassinet.
The 3-inch thickness is the main trade-off, but for a mini crib, it’s actually ideal — it fits snugly without being too bulky. The 4.5-star rating from 606 buyers backs up my experience, and I’d buy it again for my next baby without hesitation.
