Serta Tranquility Eco Firm 2-Stage Baby Crib and Toddler Mattress - Waterproof Standard Baby Crib & Toddler Mattress - GREENGUARD Gold Certified- 52" L X 27.5" W (50 Year Warranty)

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!!

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.

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.

We’ve been using this for a little over 6 months now and it is great! I worry about the foam mattresses/bed in a box stuff since they’re still pretty new and I don’t want my baby breathing that in. I definitely prefer the classic innerspring mattress for her and for the rest of my family! This mattress is great, fits snugly in the crib with no gaps, I haven’t seen any sagging whatsoever! I am pregnant again and definitely will be purchasing another one for this baby too!

This mattress was not as firm as I thought it was going to be, but it isn’t horrible either.

I have to say, I absolutely AGONIZED over a mattress for our son. I wanted a fancy organic one so badly but we just couldn't afford it at the time. So I settled on a regular one with good reviews. And it turns out I actually love it. We've been using it over 18 months now and no issues. It fits well in the Dream On Me Synergy 5-in-1 crib too. We did turn it over to the toddler side pretty soon after we got it. It's not that soft that our kiddo couldn't roll back over and I noticed he slept a LOT better that way. I love it so much we may even take it on our vacation and just toss it in the bottom of the Regalo play yard. I'd also recommend the Amazon basics jersey crib sheets. Super soft and wash well. I got two sets at my shower and loved them so much that I got two more later on.

Don't believe the complaints about the mattress deforming, it doesn't. It holds up to 125LB Great Danes with out deforming. The dogs love it and much less expensive than a purpose-made dog bed.

It arrived on time, in good condition, and fits in my little one's crib well. She's been sleeping on it for a week now and seems to sleep more soundly than she had been in her bassinet. The only issue I have is a little silly - it can be difficult to get a fitted sheet on to. Honestly I think that it's because the mattress is so thick (due to the 2 sided nature, which is actually a plus) and who doesn't have a hard time with fitted sheets, am I right?! So just try to get crib sheets with a little stretch so they don't rip, and you'll be golden.
