The shikibuton itself provides thickness, cushioning, and support; sheets, fitted covers, the original mattress cover, and protectors handle daily cleaning and protection; a moisture pad sits beneath the futon to absorb dampness from the base and remind you to air it. HIMARI and SORA are the core daily-use lines.
For buyers researching shikibuton, shikifuton or a Japanese floor mattress, the key point is how this bedding is used: on a firm, ventilated surface, folded away when needed, and cared for as part of everyday Japanese living.
