Incredibly comfortable crib mattress – soft, safe, and perfect for baby sleep
The Letmxiu Premium Crib & Toddler Mattress has been one of the best investments we've made for our baby's sleep setup. From the moment we set it up, the quality was immediately apparent — the 100% knitted fabric surface is incredibly soft to the touch, and you can tell it was designed with a baby's comfort and delicate skin in mind. The premium fleece surface is gentle and cozy without being too warm, which is important for safe infant sleep. Our baby has been sleeping noticeably more soundly since we switched to this mattress, and as a parent, there is no greater reassurance than seeing your little one comfortable and rested. The mattress provides just the right level of firmness that is recommended for infant safety while still feeling soft and cushioned. The hypoallergenic materials are a huge plus for us. Knowing that the mattress is free from irritants and safe for a baby with sensitive skin gives us real peace of mind. The surface is also easy to wipe clean, which is essential for a product that will inevitably encounter spills and messes. The fit in our standard crib was perfect with no gaps around the edges, which is critical for safety. The mattress is lightweight enough to handle easily when changing sheets but feels sturdy and well-constructed overall. If you're looking for a crib mattress that prioritizes your baby's comfort and safety without compromising on quality, this is an excellent choice. Highly recommend to any new parent setting up a nursery. One of those purchases you won't regret.

Fantastic Mattress — Soft, Safe, and Truly Well‑Made
I’m genuinely impressed with this crib and toddler mattress. The quality stood out the moment I unboxed it. The 100% knitted fabric and premium fleece surface give it a soft, cozy feel that still manages to stay breathable and comfortable for little ones. It has that perfect balance of firmness and softness, which is exactly what you want for safe infant sleep but still comfortable enough as they grow into toddler years. The 5-inch thickness makes it feel sturdy and supportive, not flimsy like some cheaper options. I also appreciate that it’s non‑toxic and hypoallergenic, which gives real peace of mind when it comes to sensitive skin and overall safety. Fitment was spot‑on — it sits snugly in a standard crib with no awkward gaps. Everything about it feels thoughtfully made, from the stitching to the materials. It’s one of those purchases where you can tell the manufacturer actually cared about comfort and safety. Overall, this mattress is absolutely worth it. Soft, safe, supportive, and genuinely well‑designed. I’d buy it again without hesitation. Our granddaughter hasn't complained about it even once (she is only 3 months) haha! Seriously she sleeps very well and we love it!

Letting it air out first. Soft texture, comfortable cushion.
Light, but just what my son needs. He's a thick kid. He is very dense, too 😂. So this mattress is perfect for him. He is only 18 months. Love, love, LOVE!

Excellent Quality Crib Mattress
Excellent crib mattress! It fits perfectly in our crib, and the quality is great. The mattress is firm, comfortable, and provides good support for my baby. The cover is soft and breathable, and there was no strong odor after opening. Highly recommended for parents looking for a safe and affordable crib mattress.

Great buy!!!
Stop searching for a mattress and buy this one ! I got this when my son was 5 months old and he asolutely loves it.No weird smell to it, it took about 3 full days to fully expand to its full potential. I couldn't be more pleased with this mattress. Theirs no crinkle plastic sound to it when he moves, its soft yet firm enough and safe for him to sleep on.

Amazing Quality
Wow super impressed by this mattress. Feels like a great quality adult mattress. Super soft cotton feel and comfortable. Quiet when moving around. Perfect. Baby loved it first try right out of the box. I imagine it’ll only get fluffier as it sits out of the box longer.

Not waterproof
Great mattress, but it is not waterproof so you should buy a mattress protector.

Soft and Durable! BUY IT NOW!!!
Beautiful mattress! Functions as expected. Feels so soft already and it hasn’t fully expanded as yet. My daughter is about to be 2 next month and she already loves laying on it. The box was not heavy, the mattress was snugged in there. Highly durable, holds my daughter’s weight perfectly. The mattress also fits perfectly in her princess bed. I haven’t had a reason to clean it yet but it should be easy because it came with instructions on what to use when that time comes so that’s a plus. Highly recommend! Great buy for the price!
