## Abstract

A method and system for packaging multiple bedding products. The method includes compressing a stack of individual compressed and sealed mattresses between an upper shipping support and a lower shipping support and restraining subsequent expansion of the individual compressed and sealed mattresses with bands enclosing the upper and lower shipping supports and the stack of compressed and sealed mattresses.

## Claims

### Claim 1

A method for preparing mattresses for shipment, the method comprising the steps of:
compressing individually a plurality of mattresses;
retaining the compression by vacuum-sealing each mattress individually;
placing the plurality of compressed mattresses on a first support;
placing a second support on top of the plurality of compressed mattresses;
compressing further the plurality of compressed mattresses between the first support and the second support; and
coupling the first support and the second support together to form a stack assembly, the coupling restraining expansion of the plurality of further compressed mattresses and
restoring at least one mattress to its precompression thickness.

compressing individually a plurality of mattresses;
retaining the compression by vacuum-sealing each mattress individually;
placing the plurality of compressed mattresses on a first support;
placing a second support on top of the plurality of compressed mattresses;
compressing further the plurality of compressed mattresses between the first support and the second support; and
coupling the first support and the second support together, said coupling restraining expansion of the plurality of further compressed mattresses.
