I chose this because it was bouillotte French Manufacturing and Craft. I am more than satisfied with the quality. Beautiful thick fabric, strong seams, generous padding. I bought the smallest model, but its size is already quite large and allows it to be versatile. Hot water bottles "microwaveable" filled gel or moist peat always end up emptying gradually; flaxseed should not be a problem is. The most is that compartmentalize the seams trim and guarantee a homogeneous filling. For those who wish to offer it, the parcel and packaging cared allow you to have it delivered directly to the person, no surprises. A big thank you and good luck to cushion Zenitude.
