【Commitment to Quality: Original Mattress “FUKATTO Inazuma Kai”】 This upgraded version of “FUKATTO Inazuma” combines plush comfort and firm body pressure distribution. It features an extra-thick design that resists bottoming out, even on flooring. Excellent elasticity and moisture-wicking properties ensure a comfortable sleep experience. Despite its volume, it is lightweight and foldable in three parts, making it convenient for transport and storage.

The mattress measures approximately 100×210cm with a quilting allowance of +5% to -3%. The composition includes 100% polyester fabric and polyester batting weighing about 1kg. It has a urethane foam core approximately 5cm thick and firm cotton weighing about 2kg. The product uses Mighty Top (antibacterial, deodorant, anti-mite batting) and Polity (moisture-absorbing, quick-drying firm cotton). The main body weight is approximately 4.6kg, and the total weight with packaging is about 5.55kg. Due to the nature of cotton and urethane products, there may be slight individual weight differences. This product is made in Japan.

For care, it cannot be washed in a household washing machine; consult a cleaning service instead. To prevent damage and stains, use a cover or sheet, and wash them frequently. Air the mattress in the sun or use a futon dryer to increase warmth, loft, and resilience. If the mattress fabric becomes dirty, spot clean immediately and dry thoroughly. Note that due to the nature of dyes, color fading may occur with sweat or friction.

【Feedback Improved!】 The tag pins have been removed! Based on feedback that “tag pins pierce and cause batting to protrude during removal,” the tag pins have been eliminated and replaced with a clamped tag. Please note that some items with tag pins may still exist.

Mattresses are compressed products and should be opened promptly upon delivery. Please open within a week of receipt. Depending on the environment, timing, and materials, restoration may take 1–2 weeks. Urethane mattresses naturally restore over time, taking up to a month. Different parts may restore at different times. This is due to compression characteristics and is not a defect.

For futons, airing in the sun or using a futon dryer helps inflate it more smoothly. For urethane materials, use a cloth over the mattress before applying steam ironing. The packaging plastic can be opened by hand or scissors; avoid sharp tools like cutters to prevent damage. Urethane mattresses may feel soft immediately after opening but will return to their original firmness and stabilize over time.

【Other Considerations】 Efforts are made to match the actual color as closely as possible, but color may vary due to monitor settings. Weight is approximate and may vary slightly between items. The side with the sewn quality tag on the piping (product edge) is the profile (bumpy) side.
