In a word – yes!
It is not widely known but a quality down filled product (not feather, the difference is important) will have a range of benefits not least it will last and perform well far longer.
Furthermore, the health benefits from natural temperature regulation are not be underestimated – imagine the cumulative effect of a 10% improvement in sleep quality night after night for example?
So – more bang for your buck and fantastic health benefits? A good investment indeed!
