Warmth spreads from the moment it touches the skin, effectively preventing coldness in the cold season. It supports comfortable sleep with natural warmth without relying too much on air conditioning heating. ・【Excellent Breathability, Comfortable and Less Humid】 Even though it's thick, the breathable woven structure prevents stuffiness and stickiness. It provides a dry and comfortable sleep even after lying down for a long time. Recommended for those with sensitive skin and children. ・【Non-Slip All-Around Elastic】 360° all-around elastic that securely wraps the entire mattress. It doesn't slip even when you turn over and fits perfectly. Easy to put on and take off, and easy to care for. ・【Machine Washable & Antibacterial and Odor-Resistant】 You can wash it directly in your home washing machine, so it's always clean. It's less likely to lose its shape or fade, and the material dries quickly. Antibacterial and odor-resistant processing allows you to use it with peace of mind every day.
