On May 12 and 13, 2026, KURUKURU Co., Ltd., based in Ginza, Tokyo, will launch the renewed GOKUMIN mattress series, presenting three distinct models that cater to diverse sleep preferences. This collection includes the "Dual Coil Mattress Premium Hard," the "Relive Fiber Mattress Topper," available on May 12, and the "Premium Hybrid Mattress NEO" in both tri-fold and quad-fold formats, available on May 13. Each model is tailored to meet various lifestyle needs and body postures, providing a tailored sleeping experience through a range of pricing, thickness, and structural options.

Catering to Diverse Sleep Preferences

As lifestyles become increasingly diverse, so too do the demands for bedding solutions. Whether it’s the solitary dweller or a family unit, preferences vary widely based on whether individuals favor a traditional bed or a more minimalist floor setup. Understanding these nuances, GOKUMIN is committed to addressing customer desires for customized firmness, the ability to maintain current bedding while enhancing comfort, and the yearning for high-quality hotel-style sleep experiences.

This revamped mattress lineup was developed in response to feedback from customer surveys, reviews, and post-purchase requests, thereby ensuring that each mattress meets individual preferences.
