Brought this for my 4 year old who is autistic and not a good sleeper.  He usually has me up every night and really suffers as he cant switch off!  Since buying this mattress the change in his sleeping pattern is astonishing.  He has slept through the night now for 5 nights!  Im the one waking up now wondering where he is!  I cant highly recommend this mattress, as it has done wonders for my child.
