For nightly sleep, start with HIMARI or SORA. If you specifically want a spring mattress or deep sink-in cushioning on a raised bed, a Japanese shikibuton may not be your first choice; compare it with your sleep preferences, space and budget.
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.
