GOKUMIN Launches Three Types of Cooling Pillows Starting May 12 to Solve Summer Sleep Issues in Japan

KURUKURU Co., Ltd. (Headquarters: Ginza, Chuo-ku, Tokyo, CEO: Yasuhiro Sekizawa), which operates the comprehensive bedding brand 'GOKUMIN,' announced the sequential release of three types of cooling pillows to support comfortable sleep during summer, starting Tuesday, May 12, 2026. The lineup includes the 'Cool Fit Pillow' (released May 12), the 'Butterfly Zero-Gravity Gel Pillow' (released May 13), and the 'Cooling Mesh Pillow' (released May 22).

## Development Background | Addressing Hot Summer Nights with Three Distinct Approaches

The difficulty of sleeping on hot summer nights is not solely caused by heat accumulating in the head. Depending on the individual, the root of the problem varies, including stuffiness from night sweats, a pillow height that doesn't fit the sleeping posture, or localized stress on the neck and shoulders.

Based on customer surveys, reviews, and post-purchase feedback, GOKUMIN has significantly expanded its summer pillow lineup to address concerns such as 'I wake up frequently because of a stuffy pillow in summer,' 'Cooling pads are only cold at first and lose effect by morning,' and 'Gel pillows are too firm and make my head feel heavy.' With three different options varying in price, material, and structure, customers can choose the sleep experience that best suits them.

## Usage Guide

- For those concerned about night sweats/stuffiness, or wanting a fully washable pillow for children → Cooling Mesh Pillow
- For those wanting to manage the heat while maintaining a comfortable fit for the head, neck, and shoulders → Cool Fit Pillow
- For those seeking three-dimensional support for the neck and shoulders, and a zero-gravity floating sensation → Butterfly Zero-Gravity Gel Pillow

## 1. Cooling Mesh Pillow

A highly breathable pillow supervised by a senior sleep health instructor, featuring a full mesh structure to release head heat and moisture, along with a 3-zone independent design and 6-level height adjustment for a personalized fit. This model is ideal for those who wake up from night sweats or families prioritizing cleanliness.

### [Full Mesh Structure Prevents Stuffiness All Night]

By using soft 3D mesh entirely, it quickly releases the heat and moisture that tend to build up in pillows. Because it utilizes a special breathable structure rather than just a cold-touch material, it doesn't get overly cold and can be comfortably used year-round.

### [Personalized Height Adjustment via 3-Zone Independent x 6-Level System]

Adopting an innovative structure with three independent pockets to accommodate back, side, and stomach sleeping postures. By simply inserting or removing the 6 included height adjustment sheets (3 zones x 2 sheets each), users can tailor the height perfectly to their sleeping posture. It is also beneficial for those who toss and turn frequently.

## 2. Cool Fit Pillow

An integrated pillow combining cold-touch gel and memory foam. Heat easily escapes from the head, and the cooling sensation revives every time heat is released when tossing and turning. This model is for those who do not want to rely too much on air conditioning and want to balance a cool feel with a snug fit. It is also an excellent gift for Father's Day, Mother's Day, couples, or parents.

### [Integrated Cooling Gel for Long-Lasting Coolness on Hot Nights]

With a unique structure that integrates cold-touch gel and memory foam using special technology, it prevents gel cracking and shifting, issues common with add-on gel pads. The design ensures that every time the user rolls over, they touch a cool surface, maintaining a refreshing feel until morning even on extremely hot nights.

### [Memory Foam Envelops the Head, Neck, and Shoulders for a Perfect Fit]

The memory foam slowly contours to the shape of the head, gently dispersing the weight of the head, neck, and shoulders. Because it adheres without gaps, it firmly supports any sleeping posture, whether on the back, side, or stomach. It is highly recommended for those concerned about neck or shoulder fatigue upon waking, or those whose posture is unstable due to frequent tossing and turning.
