We bought this for my toddler son as his newborn baby sister took over his crib. We decided to just go with a twin sized bed and put bedrails all around it instead of getting toddler bed then twin.He was not a good sleeper at all and I was worried it would take him awhile to get used to the bed but he has taken to it from day one and it is thanks to this mattress!! It is extremely comfortable and I truly feel that thanks to it being completely organic cotton, no chemicals whatsoever, is helping him to sleep throughout the night. Exceptional product, worth every penny. Plan to get one for my daughter when she gets a bit older. Thank you!
