Worth every penny!
Fantastic crib mattress. It feels so comfortable and I notice that my son sleeps much better on it than his old one.

Also good for cats
Added the crib sheets and before we could put it in the crib, it was already being tested. The baby also loved it. It’s firm but soft and thick. Seems like good quality thus far.

Great mattress for toddler bed, soft and comfortable and good price point
I bought this mattress for when my child transitioned into her first toddler bed. it fit perfectly and was very comfortable. It also was a great price point and quality was great.

Quality
This is a good mattress. My one son who 2.5 has used this mattress since day one and it is still supportive and shows no wear on it. I actually repurchased this for my 3 year old, for his bed and he loves it. In 2.5 years it has not sunk in the middle like the other purchases for my 3 year old. Definitely worth the money.

Not as waterproof as I thought it would be
I thought this mattress was good value for the money we needed a good mattress quick for our toddler and it is a good cheaper option. It was labeled to be waterproof but the material soaks ip liquids and leaves stains from said liquids even with a mattress cover which bummed me out. I pull have preferred a material of the mattress to be something you could wipe with disinfectant wipes. It was easy to set up but I don't agree with it being waterproof.
