In response to requests from ISPA members for long-term historical data about the mattress industry, ISPA has compiled selected industry data from all available reports that we have published since the 1970s.
In making this information available, it is important to bear in mind that our data collection criteria and procedures, as well as presentation formats, have changed several times over time years. This was especially true with regard to the monthly and quarterly data sets.
To help members identify when these changes have occurred, hard breaks in the spreadsheets indicate major shifts. For example, for a number of years (1993-2002), ISPA used the sample data from the monthly and quarterly data to estimate industry-wide activity. ISPA discontinued this practice in 2003. To transition from one of these shifts to the next, we have presented the data for the transitional years in both the “old” and the “new” manner.
