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!

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!

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

Plush Full size crib mattress
This mattress is very nice. It’s springy and plush. The fabric is very soft and easy to clean. The thickness is great. I was very surprised by how light weight it was while being so fluffy.
