Developer's Vision | The Demand for "Sleep That Doesn't Choose a Place" - "I Want to Sleep Properly Even Outdoors"

The scenarios requiring bedding are diversifying yearly, including car camping, camping, sudden overnight guests, and napping during remote work. However, commercially available leisure mats and simple mattresses have issues such as "the hassle of bringing a separate pillow," "the pillow moves away during sleep," "too thin causing a bottoming-out feeling," and "the back slips on flooring or in the car," often failing to replicate "true sleep."

Japan-origin bedding brand GOKUMIN developed the pillow-attached, 5-fold portable mattress "Nemutrip Mattress" to meet the need to "bring a home-like sleeping comfort anywhere." By integrating the pillow and mat into one unit, it resolves common complaints about sleeping outdoors—forgetting items, shifting, and bottoming out—delivering a quality sleep experience even on the go.

Product Features

[Comfortable Design for Deep Sleep While Traveling] This pillow-attached mattress was created to change the experience of feeling tired after sleeping during car camping or camping. The firm 4.5cm urethane supports the body and reduces unevenness from the ground or seat. The design firmly supports the head, realizing a home-like sleeping comfort even away from home. It supports comfort the next morning in a wide range of situations, including car camping, napping, and outdoor activities.

[High-Density Structure Resistant to Sagging Even with Long-Term Use] To withstand nightly tossing and turning and prolonged use, it employs a high-density urethane that is densely packed. The material, which resists deformation and boasts a recovery rate of 99.1%, distributes body pressure and reduces strain on the body. With a firmer feel that prevents excessive sinking, it supports a natural sleeping posture. It fits easily regardless of gender or body type and offers durability that resists sagging over long periods. It is a high-grade specification combining comfort and reliability.

[Easy-to-Carry 5-Fold Storage Design] Recognizing the importance of storability for outdoor gear, it features a compact 5-fold design. When not in use, it can be folded for space-saving storage, fitting neatly in a car. Equipped with a handle for easy carrying, it is versatile for camping, car camping, napping, and disaster preparedness. It is a highly practical mat that creates a comfortable resting space simply by spreading it out when needed.

[Comfortable Specifications for Breathability and Cleanliness] The cover that touches the skin uses a thick 3D honeycomb mesh material with excellent breathability. It allows heat and moisture to escape, providing a comfortable sleep that resists stuffiness even during long use. Furthermore, it is treated to resist odors and bacteria, maintaining cleanliness even in situations with sweat and dirt. The cover is removable and washable, making maintenance easy. The specifications are thoughtfully designed for hygiene, ensuring comfortable use outdoors or in a car.

[Safe Design Pursuing Reliable Quality] As bedding used daily, quality and safety were thoroughly prioritized. With a low-formaldehyde specification that reduces chemical substances, it is easy to use even in homes with small children, and quality and safety have been confirmed by a third-party organization. Furthermore, it is produced in factories compliant with international standards for quality management and environmental management (ISO9001 and ISO14001), with meticulous control over details. This mattress pursues reliability for long-term, worry-free use, whether traveling or at home.
