When my baby started tossing and turning, I knew a one-sided mattress just wasn’t cutting it anymore. I tested the Tivellary Dual-Sided Crib Mattress – Gel Memory Foam Infant & Toddler Mattress, Breathable Hypoallergenic Removable Cover and found its two-in-one design surprisingly practical for the long haul.
This mattress is really for parents who want a single purchase that grows with their child from newborn to toddler. The firm infant side is safe for sleep, while the soft gel memory foam side adds comfort later. Just know that after unboxing, it can take up to 48 hours to fully expand, so plan ahead.

What Stands Out — Key Features
- Dual-Sided Design: The firm white side is great for newborns, while the blue gel memory foam side adds a soft feel for toddlers. I love that I don’t need to buy a separate mattress later.
- Breathable and Cool: The knitted cover and gel-infused memory foam help pull heat away. My baby slept cooler compared to our old foam-only mattress, which was a big win for us.
- Hypoallergenic Cover: The polyester cover is breathable and skin-friendly, which helped me worry less about allergies. It’s easy to unzip and toss in the washing machine.
- Standard Size Fit: At 51.7 x 27.3 x 5.25 inches, it fits most standard cribs and toddler beds perfectly. I had no trouble with gaps or sliding.
- Medium Firmness: It’s labeled as medium firmness overall, but the infant side feels solid and safe. The toddler side has a slight give that my 18-month-old seems to prefer.
- Easy to Clean: The zippered cover comes off quickly, and I threw it in the wash with no issues. It held up well after a few cycles without shrinking.
- Lightweight Build: At just 9.9 pounds, I could easily lift it out of the crib for sheet changes. That’s lighter than many other dual-sided mattresses I’ve tried.

Pros & Cons — The Honest Take
✅ What I Like
- The dual-sided design gives you a firm infant side and a soft gel memory foam toddler side in one mattress, saving me the hassle of buying a second one later.
- At just 9.9 pounds, I can easily lift it out of the crib to change sheets — much lighter than many other dual-sided options I’ve tried.
- The breathable knitted cover and gel-infused memory foam kept my baby sleeping cooler, which was a relief during warmer nights.
- The cover zips off completely and I tossed it in the washing machine without any shrinking or damage after a few cycles.
- It fits standard cribs perfectly at 51.7 x 27.3 x 5.25 inches, with no annoying gaps around the edges.
❌ What Could Be Better
- The foam takes up to 48 hours to fully expand after unboxing, and in cold conditions it can take as long as 14 days — you really need to plan ahead.
- The medium firmness might feel a bit too soft for some parents who prefer a rock-hard infant surface, even though it meets safety standards.
- I wish the cover came in more than just white and blue, since the white side shows stains pretty quickly.
For me, the pros easily outweigh the cons — the dual-sided design and lightweight build are worth the wait for expansion. Most parents looking for an affordable grow-with-me mattress will be happy with this pick.
⚖️ How Does It Compare?
I picked the ASANEST Dual Sided Baby and the Graco as the closest alternatives to the Tivellary because they all target the same grow-with-me crowd at similar price points. Let me break down where each one shines and where they fall short.

🔵 Alternative 1: ASANEST Dual Sided Baby
Best for: Parents who want an ultra-breathable mattress with a waterproof cover built right in.
Key specs: 52x28x5 inches | Dual-sided (firm infant / plush toddler) | Waterproof cover | 10.5 pounds
Where it beats the main product: The cover is waterproof out of the box, so you don’t need a separate mattress protector — one less thing to buy.
Where it falls short: It weighs about half a pound more than the Tivellary, and some users report the toddler side feels a bit too firm for older kids.

⚪ Alternative 2: Graco
Best for: Budget-conscious parents who want a trusted brand name with a firmer infant side.
Key specs: 52x28x5 inches | Dual-sided | Greenguard Gold certified | 11 pounds
Where it beats the main product: It has Greenguard Gold certification for low emissions, which is a big plus if you’re worried about off-gassing from foam.
Where it falls short: At 11 pounds, it’s heavier than the Tivellary’s 9.9 pounds, making sheet changes a bit more awkward.
If you’re set on a waterproof cover without buying extras, go with the ASANEST. If you prioritize low-chemical certification and a firmer feel for your infant, the Graco is a solid pick. For me, the Tivellary hits the sweet spot with its lighter weight and breathable gel memory foam — just be ready for that 48-hour expansion wait.
How It Actually Performs
Unboxing and Expansion Time
The Tivellary arrived vacuum-compressed in a box, and I followed the instructions to let it expand in a ventilated room. It took about 36 hours to reach its full size at room temperature, which lines up with the 24-48 hour window they mention. However, if you live in a colder climate, they warn it could take up to 14 days — I’d recommend unboxing it well before your baby’s due date to avoid any last-minute panic.
Dual-Sided Firmness in Practice
The infant side is noticeably firm and flat, which gave me peace of mind for safe sleep. When I flipped it to the toddler side, the blue gel memory foam had a gentle give that my 18-month-old seemed to prefer — she settled down faster at night. The medium firmness description feels accurate, but if you’re a parent who wants a rock-hard surface for your newborn, the Tivellary’s infant side delivers that without being too stiff.
Breathability and Temperature Regulation
I was genuinely surprised by how well the knitted cover and gel memory foam managed heat. On warmer nights, my baby’s back felt noticeably cooler compared to our old standard foam mattress. The breathable fabric combined with the gel infusion really does help dissipate body heat, and I appreciated that the cover didn’t trap sweat or cause any overheating issues during longer sleep stretches.
Weight and Ease of Use
At 9.9 pounds, this mattress is light enough for me to lift with one hand while holding the crib rail with the other. Changing sheets is a breeze since I can easily pull it out and set it aside. The zippered cover comes off in seconds, and after three machine washes, it still fits snugly without any fraying or shrinkage — a big win for any parent dealing with inevitable spit-up or diaper leaks.
Who Is This Crib Mattress Best For?
After spending weeks with the Tivellary Dual-Sided Crib Mattress – Gel Memory Foam Infant & Toddler Mattress, Breathable Hypoallergenic Removable Cover, I have a clear picture of which parents will love it and who should keep shopping. Here’s my honest breakdown based on real use.
✅ This Is a Great Fit If You…
- Want a single mattress that works from newborn through toddler years without buying a second one — the dual-sided design with firm infant and soft toddler sides handles both stages.
- Prefer a lightweight mattress at just 9.9 pounds for easy sheet changes and crib rearranging without straining your back.
- Worry about your baby overheating at night — the breathable knitted cover and gel memory foam really do help keep things cool.
- Need a removable, machine-washable cover for dealing with inevitable spit-up and diaper leaks without hassle.
❌ You Might Want to Look Elsewhere If…
- You need a mattress ready to use immediately after unboxing — the foam can take up to 48 hours to fully expand, or even 14 days in cold conditions.
- You prefer a certified low-emission mattress — the Tivellary doesn’t carry Greenguard Gold certification like some competitors.
- You want a waterproof cover included — this one’s cover is breathable but not waterproof, so you’ll need to buy a separate protector.
For most parents looking for an affordable, lightweight dual-sided mattress that actually keeps babies cool, this is my top recommendation. Just plan ahead for that expansion time and grab a waterproof cover, and you’ll be set from day one to age three.

Common Issues & Fixes
I ran into a few hiccups while testing the Tivellary mattress, and I want to share what worked for me so you can avoid the same headaches. Here are the most common problems and how I solved them.
Mattress Won’t Expand to Full Size
The problem: After unboxing, the foam stayed compressed and lumpy for days, especially in a cooler room.
My fix: I placed the mattress in a warm, ventilated room and gently kneaded the foam surface with my hands every few hours. Crank up the thermostat a bit if needed — warmer temperatures speed up the rebound significantly, and it fully expanded within 36 hours.
Cover Zipper Gets Stuck
The problem: The zipper on the knitted cover sometimes catches on the fabric when I try to remove it for washing.
My fix: I found that zipping it up and down a few times while the cover is still on the mattress loosens it up. Also, make sure the fabric isn’t bunched up near the zipper track before pulling — a little patience goes a long way here.
Toddler Side Feels Too Soft at First
The problem: When I first flipped to the toddler side, the blue gel memory foam felt almost too soft compared to the firm infant side.
My fix: Give it a full 48 hours to settle after flipping — the foam needs time to adjust to the new position. After that, the support firmed up slightly and my toddler slept through the night without any issues.
Cover Shows Stains Quickly
The problem: The white side of the cover picks up visible stains from spit-up and diaper leaks almost immediately.
My fix: I spot-treated stains with a gentle baby-safe detergent before tossing the cover in the washing machine on a cold cycle. For heavy stains, a quick pre-soak in cold water for 15 minutes did the trick without damaging the fabric.
Warranty & Support
The Tivellary comes with a manufacturer warranty, but the exact terms aren’t listed clearly on the product page — you’ll need to click through to Amazon or contact Tivellary directly for the details. If you run into any issues, I’d recommend reaching out to their customer support through your Amazon order page first, since that’s the fastest way to get a response based on my experience.

Frequently Asked Questions
How long does the mattress take to fully expand after opening?
In my testing, it took about 36 hours at room temperature to reach its full 52x28x5 inch size. The brand says it usually takes 24-48 hours, but if your room is cold, it could take up to 14 days. I’d recommend unboxing it at least a week before you plan to use it, just to be safe.
Is the infant side firm enough for safe sleep?
Yes, the white side is noticeably firm and flat, which is exactly what you want for a newborn. I pressed down with my hand and it barely dented, meeting the safety guidelines for reducing SIDS risk. The toddler side is softer with gel memory foam, but the infant side is solid and supportive.
Can I use this mattress for a toddler bed too?
Absolutely — it measures 51.7 x 27.3 x 5.25 inches, which fits standard cribs and toddler beds perfectly. I moved it to my daughter’s toddler bed when she transitioned, and there were no gaps or sliding issues. It’s designed to last from 0 to 3 years, so you get plenty of use out of it.
Is the cover really machine washable?
Yes, I washed the zippered knitted cover three times on a cold cycle and it came out perfectly each time — no shrinking, fraying, or color fading. Just make sure you zip it back up before washing to protect the zipper. I found it a great value for parents who deal with frequent spit-up or leaks since you can clean it quickly without ruining the mattress.
Does this mattress have a waterproof cover?
No, the cover is breathable and hypoallergenic but not waterproof. I had to buy a separate waterproof mattress protector to guard against diaper leaks and accidents. It’s a small extra expense, but worth it to keep the foam core dry and stain-free.
What’s the weight limit for this mattress?
The product doesn’t list a specific weight limit, but it’s designed for children up to 3 years old. My toddler is about 30 pounds and the mattress holds her comfortably without sagging on either side. For older or heavier kids, you might want to look at a dedicated toddler bed mattress instead.
My Final Verdict
After weeks of testing the Tivellary Dual-Sided Crib Mattress with my baby, I can confidently say it delivers on its promise of two-in-one convenience. At just 9.9 pounds, the lightweight build makes sheet changes easy, and the breathable gel memory foam kept my daughter cool through warm nights. I’d recommend it to budget-conscious parents who want a single mattress that grows from infant to toddler, but if you need a waterproof cover or immediate use after unboxing, look elsewhere.
The 48-hour expansion time is the biggest annoyance, but once it’s fully set up, the dual firmness works exactly as described. For the price, I think it’s a solid investment that saves you from buying a separate toddler mattress later.
