Claims17
A mattress construction, comprising:
- a) an innerspring construction defining an upper primary surface and including at least one spring;
- b) a laminated liquid-resistant barrier layer for discouraging liquid passage, said barrier layer itself comprising:
- a liquid impervious layer for discouraging liquid passage;
- and
- a structural backing layer comprised on non-woven polypropylene fibers, said structural backing layer attached permanently to said liquid impervious layer;
- c) attachment means for attaching said laminated liquid-resistant layer to said innerspring construction such that said laminated liquid-resistant layer is positioned adjacent said upper primary surface of said innerspring construction;
- and
- d) a removable cover.

A mattress construction, comprising:
- a) an innerspring construction defining an upper primary planar surface and including at least one spring;
- b) a laminated liquid barrier layer for discouraging liquid passage, said barrier layer itself comprising:
- a liquid resistant layer for discouraging liquid passage;
- and
- a structural backing layer in planar contact with and permanently attached to said liquid resistant layer;
- c) attachment means for attaching said structural backing layer of said laminated liquid barrier layer to said innerspring construction such that attachment of said structural backing layer causes said liquid resistant layer to be likewise attached relative to said innerspring construction and whereby the presence of said structural backing layer tends to reduce tearing of said liquid impervious layer caused by said attachment means, and
- d) a cover.
