Side sleepers may prefer different levels of cushioning at the shoulder and hip. SORA is approximately 12 cm thick, with 50% wool in its comfort filling and a fuller, balanced-medium feel. HIMARI is approximately 10 cm thick in total, including an approximately 8 cm firm support core, with a medium-firm feel. Compare those constructions with the mattress you use now and your own preferences. Neither model has a published pressure measurement here; these are construction descriptions, not comfort test results.
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 changes the support and feel, so the shikibuton may not feel as intended.
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.
