A classical theorem of Rogers states that for any convex body $K$ in
$n$-dimensional Euclidean space there exists a covering of the space by translates of
$K$ with density not exceeding
$n\,\log \,n\,+\,n\,\log \,\log \,n\,+\,5$. Rogers’ theorem does not say anything about the structure of such a covering. We show that for sufficiently large values of
$n$ the same bound can be attained by a covering which is the union of
$O\left( \log \,n \right)$ translates of a lattice arrangement of
$K$.
