A no-gel latex foam is formed by curing a no-gel latex foam froth on a water vapor permeable foraminous support that has been coated with a flock. During curing, the foam froth dehydrates through an upper free surface and at its lower supported surface through the flock and the foraminous supporting means. When the cured foam is removed from the foraminous supporting means, a portion of the flock adheres to the foam undersurface and another portion of the flock is left as a residue.

A method for making no-gel latex foam comprising (a) distributing a layer of loosely associated flock onto a water vapor-permeable supporting means, (b) deposited a froth of uncured no-gel latex foam onto the supporting means over the flock layer to enable the froth to make surface contact with the layer of loosely associated flock, the supporting means being sufficiently layered with flock to enable the flock to prevent the uncured froth from directly contacting the supporting means through the flock layer, (c) heating the latex foam froth to dehydrate, cure and form the no-gel latex foam, and (d) separating the foam from the supporting means at the flock layer, the thickness of the flock layer being controlled to permit division of the flock layer into a first portion that is adhered to the separated foam to form an exposed surface coating of flock on the foam due to adhesion between the uncured foam froth and the loosely associated flock in contact with the foam froth, and a second nonadherent portion that remains freely disposed on the supporting means, and wherein the constituents of the foam adhered surface coating of flock are of a size and material that does not prevent the no-gel latex foam from being resiliently stretchable substantially in the same manner as without the flock coating.
