Abstract: Given a Class ${\cal F}$ of posets, let $ex({\cal F}, n)$ denote the
maximum number of covering pairs achieved by an $n$-element poset
in ${\cal F}$. We determine this number of the class of $N$-free
of Bollobas and RRival, who originally, ask for $ex({\cal L}, n)$
${\cal L}$ denotes the class of all lattices.
