☆Product Description☆

Brand: BRAIN SLEEP
Product Name: BRAIN SLEEP Mattress Plus Float
Color: White
Size: Single: Approx. W100 x L195 x H15/19 (cm)
Country of Manufacture: Japan


[NASA-Proposed Zero-Gravity Relaxing Posture]
It features a unique Float Structure that replicates the natural posture humans adopt in space (neutral posture). Your shoulders sink in smoothly, and your legs are slightly elevated, minimizing strain on your entire body. Experience blissful sleep as if you're floating in the air!

[Ultra-Body Pressure Dispersion for Smooth Turning]
The 7-layer cushioning material supports different body parts with varying firmness (Zoning Support). It prevents excessive sinking, maintains the ideal sleeping posture, and allows for effortless turning without expending extra energy, ensuring deep sleep until morning and a remarkably refreshed feeling upon waking.

[Exceptional Breathability & Washable with a Shower!]
Over 90% of the material is air, preventing heat and moisture buildup for year-round comfort. Furthermore, not only the cover but also the mattress core (inner material) can be washed with a shower! This inhibits the growth of dust mites and mold, keeping it clean and like new at all times.
