4. ISPA’s Mattress Industry Trends Report
Summary
Mark and Mike speak to Mary Thorpe, Director of Industry Research and Analytics for ISPA, to dig into the methodologies, questions, and take-aways from their latest Mattress Industry Trends Report — which showed the fourth consecutive year of decline for the category.
Key Take-Aways
The U.S. mattress industry had a brutal 2025. According to ISPA, wholesale mattress units fell by 6.7% and dollar value fell by 4.0%, making last year a continuation of recent declines.
ISPA measures production, not retail sales. The report tracks mattresses produced or imported into the U.S., not what consumers ultimately bought.
Most of the domestic numbers are based on real data. Roughly 80–90% of the domestics totals come from actual manufacturer submissions, with the remainder estimated using ISPA's methodology.
Import tracking remains the biggest blind spot. Misclassified shipments and inconsistent customs codes make imported mattresses the least certain part of the industry's estimates.
Stationary foundations continue to disappear. They now accompany only about 40% of mattress shipments, roughly half the attachment rate of two decades ago.
Consumers continue moving toward larger mattresses. The long-term shift toward queen and king sizes helped cushion the decline in dollar value relative to unit volume.
No one has a clear explanation for the prolonged downturn. Even ISPA views the industry's slow recovery as one of its biggest unanswered questions.
Better participation from producers would improve the data. ISPA's top request is for more manufacturers to submit their numbers so future reports require less estimation.
