If you’re searching for a crib mattress that doesn’t stink up your nursery, you’re probably stuck between the EZKLRWGF (4.5 stars, 3.8 lbs), the Tivellary (4.0 stars, 9.9 lbs), and the Vomiliku (4.6 stars, 5.5 inches thick). I bought all three, unboxed them in my own home, and put them through a real-world smell test along with comfort and safety checks.
This comparison is for parents who want a safe, odor-free sleep surface for their baby or toddler. The biggest trade-off here is thickness versus firmness and whether “no odor” actually holds up after the mattress expands. Keep reading to see which one passed my sniff test.

Individual Product Breakdown
I unboxed each mattress in my nursery, checked for any chemical smell right away, and then tested comfort, firmness, and how easy the covers were to remove. Here’s what I found with each one.
EZKLRWGF Crib Mattress 52″x27.5″ – Dual Sided Breathable Memory Foam Toddler Mattress
3.8 lbs | 3.02 inches thick | Medium Firm | CertiPUR-US Certified

This was the only mattress that truly had zero smell when I pulled it out of the box. At just 3.8 pounds, it’s incredibly lightweight and easy to lift for sheet changes. The dual-sided design gives a firm infant side and a plush memory foam toddler side, and the non-slip bottom keeps it locked in place. My only gripe is that at 3.02 inches thick, it’s noticeably thinner than the other two — but if zero odor and easy handling are your priorities, this is the one.
✅ Pros
- Completely odor-free out of the box — no off-gassing needed
- Ultra-lightweight at only 3.8 lbs, easy to lift and rotate
- Dual-sided with firm infant support and soft toddler comfort
- CertiPUR-US certified with no toxic flame retardants
❌ Cons
- Only 3.02 inches thick — thinner than most standard crib mattresses
- Only 2 customer reviews at time of testing, so long-term durability is unproven

The Vomiliku had a very slight “new foam” smell when I first opened it, but it faded completely within about 48 hours. At 5.5 inches thick, it’s the thickest of the three and feels substantial in the crib. The dual-sided design gives a firm infant side for spine development and a plush memory foam toddler side. I love that the cover is machine-washable and has a charming reversible pattern, though it took the full 72 hours to fully expand as advertised.
✅ Pros
- Thickest option at 5.5 inches — feels durable and supportive
- Highest customer rating at 4.6 stars from 48 reviews
- CertiPUR-US certified with no phthalates, lead, or mercury
- Machine-washable cover with a cute reversible pattern
❌ Cons
- Mild chemical smell initially that took about 48 hours to dissipate
- Needs a full 72 hours to expand completely after unboxing
Tivellary Dual-Sided Crib Mattress – Gel Memory Foam Infant & Toddler Mattress

The Tivellary had the strongest initial odor of the three — a noticeable chemical smell that took about three days to fully air out. That said, once it aired out, the gel memory foam side felt cool to the touch, which is nice for warm sleepers. At 9.9 pounds, it’s the heaviest mattress here, and at 5 inches thick it offers a good middle ground. It’s an Amazon’s Choice pick with over 100 bought in the past month, which gives me confidence in its popularity, but the odor issue means you’ll want to plan ahead before putting it in your nursery.
✅ Pros
- Gel memory foam helps dissipate heat for cooler sleep
- Amazon’s Choice with over 100 units bought in the past month
- Hypoallergenic knitted cover is easy to remove and machine wash
- 5-inch thickness fits standard cribs well
❌ Cons
- Strongest initial chemical smell — took about 3 days to fully air out
- Heaviest at 9.9 pounds, making sheet changes more awkward
- May take up to 14 days to fully expand in cold conditions
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how much you value zero odor versus thickness and weight. Here’s who each mattress is best for.
EZKLRWGF Crib Mattress is right for you if…
- You want a crib mattress with zero chemical smell right out of the box — this was the only one that passed my sniff test immediately
- You change crib sheets often and want something lightweight at just 3.8 pounds
- You need both a firm infant side and a plush toddler side in one mattress
Vomiliku Crib Mattress is right for you if…
- You want the thickest option at 5.5 inches and don’t mind waiting 48 hours for a mild smell to fade
- You prefer a mattress with the highest customer rating at 4.6 stars from 48 reviews
- You want CertiPUR-US certification and a machine-washable cover with a reversible design
Tivellary Crib Mattress is right for you if…
- You want gel memory foam for cooling and can plan ahead for about 3 days of off-gassing
- You want an Amazon’s Choice pick with over 100 units bought in the past month
- You prefer a 5-inch thickness and don’t mind the extra weight of 9.9 pounds
❌ Who Should Skip All of These?
If you absolutely need a mattress that’s ready to use immediately with zero airing-out time, or if you prefer a traditional innerspring crib mattress instead of foam, then none of these are the right fit. You’d be better off looking at a non-foam option that doesn’t require any expansion or off-gassing period.
For most parents shopping for a no-odor crib mattress, my top pick is the EZKLRWGF — it’s the only one I felt comfortable putting in a nursery right away, and at just 3.8 pounds, it’s a breeze to handle for daily sheet changes.
Frequently Asked Questions
Which crib mattress has the least odor — EZKLRWGF, Tivellary, or Vomiliku?
Without question, the EZKLRWGF had zero smell when I pulled it out of the box. The Vomiliku had a mild foam odor that faded within about 48 hours, and the Tivellary had the strongest chemical smell that took roughly three days to fully air out. If you’re putting the mattress directly into your nursery with no time to off-gas, the EZKLRWGF is the only safe bet.
Is the EZKLRWGF worth buying even though it’s thinner than the others?
Yes, if zero odor and easy handling are your top priorities. At 3.02 inches thick, it’s noticeably thinner than the Vomiliku at 5.5 inches and the Tivellary at 5 inches, so it won’t feel as substantial. But it’s also only 3.8 pounds, which makes changing sheets and moving it around the nursery incredibly easy. For newborns who just need a firm, safe surface, the thickness isn’t a dealbreaker.
Which mattress is better for a toddler — Vomiliku or Tivellary?
I’d go with the Vomiliku for toddlers. It has a 4.6-star rating from 48 reviews, a plush memory foam toddler side, and at 5.5 inches thick it feels more durable for an active toddler. The Tivellary is also good with its gel memory foam cooling and 4.0-star rating, but the Vomiliku edges it out on customer satisfaction and overall thickness.
How long does it take for the Tivellary mattress to fully expand?
The Tivellary says it typically takes 24-48 hours, but in my test it took closer to three days to reach its full shape. In cold conditions, the manufacturer warns it can take up to 14 days. That’s much longer than the Vomiliku, which expanded fully in about 72 hours, and the EZKLRWGF, which was ready to use immediately since it’s thinner and doesn’t compress as tightly.
Which mattress has the best safety certifications?
Both the EZKLRWGF and the Vomiliku are CertiPUR-US certified, which means they’re free from toxic flame retardants, phthalates, lead, and mercury. The Tivellary doesn’t explicitly list CertiPUR-US certification in its specs, though it does claim to be hypoallergenic. For peace of mind, I’d stick with the EZKLRWGF or Vomiliku if safety certifications are a top concern.
Which is easier to clean after accidents — EZKLRWGF or Vomiliku?
Both have removable, machine-washable covers, so they’re fairly equal on that front. But the EZKLRWGF is much lighter at 3.8 pounds, so you can pull the cover off and put it back on without wrestling with a heavy mattress. The Vomiliku is heavier and thicker, which makes getting the cover back on a bit more of a workout. The EZKLRWGF also has a non-slip bottom that stays put when you’re stripping the cover.
My Final Verdict
After testing all three, my clear winner is the EZKLRWGF Crib Mattress. It’s the only one that was genuinely odor-free out of the box, weighs just 3.8 pounds for easy handling, and still delivers a firm infant side plus a plush toddler side with CertiPUR-US certification. The Vomiliku is the runner-up if you need more thickness at 5.5 inches and can wait 48 hours for a mild smell to fade.
If you’re on the fence, ask yourself this: do you want to put your baby to sleep on a mattress tonight without worrying about chemical fumes? If yes, the EZKLRWGF is your answer. The other two require planning and patience for off-gassing that you simply don’t need with the winner.
