Side sleepers usually want more cushioning at the shoulder and hip than back sleepers, so the fuller option is often the better starting point: SORA is approx. 12 cm thick, with a 50% premium wool blend and a balanced medium feel. HIMARI, approx. 10 cm with a firm support core, suits side sleepers who prefer steadier, firmer support.
How to choose
- Mostly on your side, and firm surfaces feel too hard: start with SORA 宙.
- You change position through the night and like stable support: HIMARI 日葵 is designed for back and side sleepers who prefer a steadier surface.
- Pillow height: on a shikibuton, as on any bed, side sleepers generally need a pillow that fills the space between the head and the shoulder.
A base that supports the feel
Use either model on a firm, level surface. A soft base underneath does not add comfort; it reduces support.
Comfort is individual
A shikibuton is bedding, not a medical device, and makes no claim to relieve pain. Return rules differ by country and are set out on each country’s Terms page, so compare the specifications carefully before ordering.
