The BrainSleep Cool series of functional cooling bedding, designed to address sleep challenges unique to the summer season, has continued to see rising demand since its launch in 2023, amid increasingly severe heat and humidity. Cumulative sales in FY2024 grew 165% year-on-year, and within the comforter category, sales in April–May 2025 exceeded 200% compared to the same period last year, showing remarkable growth.
Starting in July 2025, limited displays and sales have also begun at Tokyo Interior Kisarazu.
