I bought two of these mattresses for bunk beds in a guest room for young grandchildren.  They are super economical and will be perfectly suitable for the amount of time they will actually be used!  There was a slight chemical smell when I first unwrapped them, but that quickly dissipated within hours and I expect the little ones will not be at all bothered when they come.   I will update when the mattresses actually *et used, if there are any issues.
