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.

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.

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.

Comfy dreams for my little dreamer 😴✨
The mattress is absolutely amazing! The 100% knitted fabric with the premium fleece surface is so soft and cozy, I swear my baby feels like she’s sleeping on a cloud. She’s more comfortable, sleeps peacefully, and honestly, it makes bedtime a little happier for both of us. The mattress is firm enough to be safe for baby while still giving a plush, comfy feel. Easy to clean and high-quality — exactly what I wanted for her nursery. Pros: Super soft premium fleece surface Comfortable yet firm enough for baby’s safety Easy to clean and maintain High-quality construction Cons: Baby might never want to leave the crib (bonus problem 😅) You may be tempted to nap in there yourself Verdict: Amazing. A perfect balance of comfort and safety — my baby sleeps happy, and so do I!

Delivery time EXCEEDED 6 DAYS
Product is very nice,fabric feels wonderful and 2 sided memory foam is easily identified by the touch, firm/plush yet stable support. Would like to have had a removable,washable waterproof protector included with the mattress, and quicker than 5 day unfold/ fluff time, but still once flat began to expand and without any foul chemical odor. Overall Mattress is very nice, especially for price point. Other request would be more accurate delivery time stated. Was purchased because of next day delivery promise and it was for my grandson who lives in another city,and trying to meet a Sunday evening deadline before family was to return to hectic schedule of the work week. While the seller shipped the item IMMEDIATELY AFTER PAYMENT WAS CONFIRMED, IT LEFT PHOENIX ARIZONA that day, and landed in Hebron KY, later that same evening/ early morning, and was to the facility for delivery the next day. It was going to Middletown Ohio which is only about an hours drive away the item sat in a warehouse DORMANT from early a.m. Monday morning which was the original DELIVERY DAY, which never happened, was moved to next day delivery again twice from Tuesday, NO SHOW, then told FRIDAY, AGAIN NO SHOW, and finally tracked and updated that it had left KY late Friday evening for Ohio, and early Saturday received in the Ohio reception center, again not leaving for delivery until 10am Saturday and yet not arriving until 1 p.m Saturday afternoon, and they still had to unpack and unroll and let flatten and fluff for 5 more days, so my grandson has still not been able to sleep in a crib, and has been stuffed into a playpen yet another night. I am hopeful with today being Wednesday and over 10 days since I ordered it that he will be able to use it this evening. So final review PRODUCT IS VERY NICE QUALITY,FABRIC n VALUE, SELLER GOOD RESPONSE TIME, SHIPPING FACILITY TIME MANAGEMENT VERY POOR COMMUNICATION AND TIME MANAGEMENT

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!

Its soft, comfortable, lightweight. Definitely a great mattress compared to others I've seen. Inflating didn't take long. Usually mattress in a bag smell musty, this one didn’t.
