Best pillow I've ever used it's super supportive while staying cool and soft, it's literally the perfect pillow and I'd recommend it to anyone it is slightly firmer than the original bamboo pillow but it's full size so you can use your own pillow case if you want to and it's not like a rock or anything I'd rate it as 6.5/7 out of 10 for firmness so I nice support but still cradles your head and moulds to how you move and sleep perfect for all positions since I've tested, back, side and stomach and it supports all so all round great and 10/10
