This one is, for the right sleeper. Its fill blend, 20% bamboo fibre and 80% siliconised polyester fibre, makes for a supportive, higher-loft pillow that stays breathable and, because there's no foam core, can go through the washing machine as a whole unit — something most bamboo pillows with a memory foam centre can't do. The trade-off is that it won't mould and hold a shape around your head and neck the way a memory-foam bamboo pillow does. If you want that close, contouring support, a foam-based bamboo pillow will suit you better; if you want a genuinely breathable, fully washable option, this is a solid choice.
