摘要 |
The invention is directed to a rigid article comprising a soft foam member, preferably open cell polyurethane, adhered to at least one surface of said soft foam member, a hard polyurethane resin member; said adhesion being obtained by way of penetration of hard resin affording material into cells of said soft foam member for a distance sufficient to provide a substantially permanent bond between said two members, after curing said hard resin-affording material; and said hard resin member is sufficiently thick to provide configurational support for said article. Normally, the article includes a cover member. |
