## Description

Serta’s Tranquility Eco Firm Crib and Toddler Mattress achieves a strong, stable and safe sleep surface that’s made especially for your growing baby. Built with 120 heavy-duty innerspring coils for long-lasting firmness, air vents to keep it fresh, plus a durable two-sided design, it will withstand years of use. Just flip it as your child grows; it’s hardworking on both sides. One side provides the ideal firmness for infants while the other offers a layer of natural cotton for toddlers. Designed by the same brand that’s been leading the way in mattress innovation and technology for more than 80 years, Serta’s crib and toddler mattresses deliver the same quality craftsmanship and attention to detail as their adult mattresses. All Serta crib mattresses are GREENGUARD Gold Certified and meet the strictest standards offered by the GREENGUARD Environmental Institute, which recognizes products with low chemical emissions, contributing to improved indoor air quality.

Review: Must have! - I decided to purchase this mattress to replace the Graco foam mattress that came with our crib due to concerns about toxic emissions. This mattress carries the Green Guard certification for low chemical emissions, and is very well constructed - it seems like it will last for a long time. The mattress is a perfect fit for the standard crib - leaving no gaps are spaces along the edges. There is an infant side and a toddler side (the infant side is clearly marked on the mattress). This mattress is also very quiet - does not make crunchy noises when the baby moves around. Highly recommend!!
Review: Great mattress! - Love this mattress! We have used our current one for 2 years now and just purchased our second for our next baby. Mattress has held up great, no rips or indentations, and is still firm but comfy. Also, the green guard gold certification is a must for me! I knew I wouldn’t purchase another mattress other than this one for our second baby.

### ⭐⭐⭐⭐⭐ Great mattress! (2nd time mom)
*by O***. on February 14, 2019*

Awesome mattress! My son is 9mo old and almost 25lbs so we needed a firm mattress that supports his weight. This does the trick! People say you can feel the coils, which is kind of true that you can feel slight grooves if you run your hand over the mattress, but if you lay on it, you don’t feel it. You just feel well supported and comfy. I had my 3.5yr old son lay on it on his belly cheek down on the mattress and he said it was great! I weigh about 135lbs and it supported my weight so I have no doubt we’ll be using this mattress for years as he grows into toddlerhood.
