I recommend it
I’m absolutely delighted with this mattress! It offers excellent firmness and support, yet is comfortable enough for my little one as they transition from crib to toddler bed. The dual-sided design was a fantastic bonus — nice and firm for infants, then a slightly softer side as they grew. The hypoallergenic materials feel safe and high-quality, and it fits perfectly with our crib setup. Easy to keep clean and totally worth the investment. Highly recommend for any parent wanting a reliable, premium mattress for their child.

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!

Crib mattress
I purchased this crib mattress for my baby and I’m really happy with it. The quality is great it feels firm enough for safe sleep, but still comfortable. My baby sleeps well on it and I feel at ease knowing it’s supportive. The size fit perfectly in the crib with no gaps, which gives me peace of mind. It’s also lightweight, which makes changing sheets super easy. No smell , easy cleaning. Overall, I’d definitely recommend this crib mattress to other parents looking for something safe, comfortable, and affordable. Compatible with Delta baby crib

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

Bought it twice
This mattress is fantastic! The 5” thickness is perfect—firm yet comfortable for my little one. Had to buy it TWICE. The hypoallergenic, non-toxic materials give me peace of mind, and the knitted fleece surface feels soft and cozy. Fits perfectly in our crib and toddler bed, and cleaning is super easy. Definitely worth it for a safe and comfy sleep!
