SORA 宙 is available in 200 × 100 cm and 200 × 140 cm, with an approximate thickness of 12 cm. Its 100% cotton outer surrounds a filling of 50% premium wool and 50% polyester. It is the flagship model, designed for a balanced, medium feel with slightly softer, fuller cushioning than HIMARI 日葵.
Use this answer as a buying guide before choosing between HIMARI and SORA: compare feel, thickness, storage, available size, and whether you want everyday Japanese bedding or a fuller flagship shikibuton.
