DE・MON Exhibits "Try-Before-You-Buy" Mattress Booth at "Million Fes 3 in Hakata Dontaku Idol Festival"

ULIFE Inc. (HQ: Chuo-ku, Tokyo; CEO: Takashi Sugiyama), through its bedding brand "DE・MON", exhibited at the "Million Fes 3 in Hakata Dontaku Idol Festival," a live event organized by WASH HOUSE held on Tuesday, May 5, 2026, at Bayside Place Hakata in Fukuoka. At the venue, a free trial booth for the DE・MON mattress (10cm model) was set up, providing a space where visitors could actually lie down and experience the concept of an "devilishly good sleep." ■ Experiencing "Hard-to-Convey-Online Bedding" in a Real-World Setting In recent years, while the bedding market has seen a trend towards e-commerce, the need for the experiential value of "trying it out by sleeping on it" remains high. Voices like "You can't know until you actually sleep on it" and "I want to test the firmness and how it feels when I turn over" are common, and the demand for pre-purchase trials remains strong. Based on this background, DE・MON continues its efforts to focus not only on online advertising but also on creating "places for actual experience." At this event, single and double-sized beds were set up, displaying the DE・MON mattress (10cm) for visitors to try freely. At the venue, natural communication unique to a live event was observed, with visitors lying down to check the comfort, sharing impressions with family and friends, and even idol performers visiting the booth and posting on social media. ■ Sharing Experiences in Visitors' Own Words through Social Media The booth also ran a social media-linked campaign where those who posted on X or Instagram after their trial received an original eye mask. The posts included photos of them lying on the mattress, their impressions of the experience, and the atmosphere of the event, resulting in promotion through the visitors' own words. DE・MON believes that the actual experience of touching the product, rather than "words created for advertising," is what helps people get to know the brand. ■ Customers Have Also Voiced Their Comfort During Sleep Customers using the DE・MON mattress have shared feedback such as: *Impressions are based on individual use and may vary. 60s Male: The moment I lay down, the feeling of my body sinking in was so comfortable, and I was surprised by how light my body felt the next morning. 40s Female: Even when my child turns over next to me, my sleeping posture isn't disturbed. The whole family uses it. 50s Male: Since I switched to this mattress, I can sleep soundly until morning. I really feel the high level of pressure distribution. 40s Female: Even though it's 10cm thick, it provides solid support. There's no feeling of bottoming out even when placed on the floor, and it's very comfortable. ■ Second Participation in a WASH HOUSE Organized Event This is the second time DE・MON has participated in a WASH HOUSE event, following "Million Fes 2 in Island Eye" in November 2025. By continuously participating in real-world events, DE・MON is expanding opportunities for people to get to know the brand not just as an "online-only brand," but as a "bedding brand you can actually try." ■ About DE・MON DE・MON is a bedding brand developed under the concept, "Sleep is not rest, but a time for regeneration." Mr. Motoi Matsuzaki, a professor at Chiba Institute of Technology (Ph.D. in Engineering) and winner of the 2022 Ig Nobel Prize in Engineering, participates in the research and development of the mattress structure. With its unique "Kuno-ji cut structure," it aims for a "design that presupposes turning over in one's sleep." ■ Company Overview · Company Name: ULIFE Inc. · Location: NB Annex Bldg. 3F, 6-1 Nihonbashi Yokoyamacho, Chuo-ku, Tokyo · Representative: Takashi Sugiyama, CEO · Established: July 2021 · Business: Planning, development, manufacturing, and sales of bedding products ■ DE・MON Official Website: https://www.de-mon.jp PR Inquiries: r_huang@yourlife.co.jp Customer Support Center: home@yourlife.co.jp (TEL: 0120-541-898) Instagram: https://instagram.com/demon_sleep_official Facebook: https://facebook.com/demon.sleep.official X (formerly Twitter): https://x.com/DE_MON_Japan TikTok: https://tiktok.com/@demon_sleep_official LINE: https://line.me/R/ti/p/@719zbeuz YouTube: https://youtube.com/@DEMON_Sleep_Official Contact Form: https://de-mon.jp/pages/contact
