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 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.

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.

If any of you are out there trying to find a mattress that fits an IKEA crib (that's not an IKEA mattress) this one fits! This mattress is truly 52" long, most other mattresses are 51 1/2 inches, which is slightly too short for IKEA cribs, leaving too large of a gap for me to be comfortable with. Plus this is a really good firm quality mattress. I looked at loads of mattresses on Amazon, and its hard to go by the dimensions labeled because they are sometimes the dimensions of the box and not the actual mattress, but the dimensions listed on this mattress is of the actual mattress. A little more than I wanted to spend on a mattress, but it will take my daughter through to her toddler years so a good investment I think.

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.

I have bought this mattress for my firstborn so I decided to buy this again for my second one. The first mattress I bought was labeled which side was for newborn, which side was for toddler. This new one however is not labeled. It is the only complaint I have. Please make sure to start labeling for future buyers.

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!

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.

I bought this for a toddler bed for my 3 year old grandchild. It’s a perfect fit for the frame and seems very comfortable. I expect to use it for another 5 years or so with my other grandchildren.
