The Rollameter is a lightweight, portable, non-stretch, non-shrink, hygienic rool-up mattress of closed cell plastic foam designed for measuring the length of a 1st year infant. The Rollameter also is appropriate for hospital/field based research.
NB It is always desirable that infants be measured nude but for purposes of website illustration the nappy has been left on this male infant.
