The invention relates to a foam dressing with a bevelled edge and where the density at the edge is higher than the density at the central part of the foam. The high density at the edges causes gel blocking of the wound exudate thereby preventing leakage of exudate through the edges. In a preferred embodiment the foam dressing is non-adhesive. The foam dressing may have a water-impervious backing layer, which extends all the way over the top of the dressing and down to the wound-contacting surface. The wound dressing is particularly useful in treatment of venous ulcers in connection with compression bandages, as the bevelling of the edges markedly reduces the indentations in the leg following use of this dressing when compared to a dressing with straight edges.
