◆ Slat design The slatted design with gaps allows for excellent ventilation. Let the wind flow and enjoy a refreshing life! Easy to clean Cleaning robots can easily enter. ◆ Breathability "Breathability" is essential for a good night's sleep. People sweat a cupful while they sleep. If there is no way for the sweat to escape, you will feel hot and sticky when you sleep. Also, if you leave a damp futon as is, it can get moldy. SBibury's slatted design eliminates dampness in the mattress and keeps the humidity inside the futon at a comfortable level.
