<p>A batt, which may be used for a mattress, a seat cushion or a ground pad for a sleeping bag, is compressed so that it has reduced false loft and reduced false support, and is therefore more durable for consumer use. The batt is compressed so that, when subjected to use for an average life cycle (usually six years), it has a thickness reduction of less than 15 % and a reduction of load-at-half-height of less than 40 %.</p> |
